Lorraine LaRosa faced a seemingly impossible decision.

She knew how fortunate she was to have not one, but three perfect matches for a bone marrow transplant, a procedure used to treat several cancerous and noncancerous diseases, such as leukemia and Hodgkins lymphoma. The statistics for finding a perfect match can be grim. The best odds rest in an immediate family member. Otherwise, a patient must rely on the bone marrow registry and the slim chance of matching with a stranger.

Ms. LaRosa had the benefit of a large family. Out of seven siblings, four were healthy enough to be tested. And three came back as matches: her sisters Jennifer Lappe and Melissa Senatore, who live in Calverton, and her brother Jason Klinge of Southampton.

I was in tears because I didnt know what to do and who was the better choice, Ms. LaRosa said.

A sense of urgency had arrived in early 2020. Ms. LaRosa, 62, who lives in Mattituck, was undergoing frequent blood transfusions due to a lack of platelets and low red blood cells.

Things were getting pretty bad at that point, she said.

She didnt want to put the burden on any of her siblings. She called her doctor to talk through her concerns. The time had come to move forward, so the doctor took the decision out of her hands.

After careful evaluation of all three siblings health and medical histories and considering Ms. LaRosas worsening situation the doctors choice became clear. The donor would be her sister Jennifer.

Ms. Lappe understood her sisters hesitancy to ask forsuch a serious commitment. But there was never a moment of doubt. She had seen her sister struggle for years with her illness and have to endure the uncertainty of misdiagnosis and multiple procedures.

I knew she was scared, Ms. Lappe said. Id be scared with what she had to go through. But shes a lot stronger than I think she thinks she is.

Ms. LaRosa texted her sister with the news that unfortunately she would be the donor.

To me there was never a question, said Ms. Lappe, 60. Ill do whatever you need. Im in a million percent. I said, Im selfish, I love you. I want you to be around forever.

The sisters, who were always so close from a young age and grew up in a tight-knit family, would soon form an unbreakable bond one saving the others life.

Before Ms. LaRosa received an ultimate diagnosis of myelodysplastic syndrome, or MDS, in February 2020, she endured years of joint pain and symptoms that seemed to mystify her doctors. One time when her shoulder hurt, she was told it was a torn rotator cuff, which turned out to be inaccurate. Before that, when she was struggling to walk with swollen feet, a podiatrist said she had a torn Achilles tendon, but she hadnt done anything that seemed to warrant an injury typically seen in athletes. Lupus was also incorrectly diagnosed.

She struggled on a continual journey from one doctor to another.

She ended up in an emergency room on Feb. 27, 2017, and a doctor there noticed that her platelets the smallest blood cells seemed low.

Two months later, a doctor at New York Cancer & Blood Specialists diagnosed large granular leukemia, a rare cancer of white blood cells. As time went on, however, her condition did not improve.

Ms. LaRosas daughter, Taylor, described her mom as a fighter who was always optimistic and never overly concerned about her health issues.

I was more so the worrywart, said Taylor, 29. I kind of forced her to go to all these appointments and all of these doctors chasing all of these kind of vague symptoms. No one could kind of come up with what was going on.

A 2009 Mattituck High School graduate, Taylor works as a physician assistant at Weill Cornell Medical Center in New York City. She connected her mom with Dr. Gail Roboz, who specializes in hematology/oncology, in November 2017. Dr. Roboz became well known as the doctor for Robin Roberts, an anchor of ABCs Good Morning America, who was diagnosed with MDS in 2012.

[Dr. Roboz] kind of took on my case and was monitoring me and was saying my blood didnt really make any sense, Ms. LaRosa said. There were mutations in my blood that werent making sense for the large granular leukemia diagnosis.

Extensive testing revealed that Ms. LaRosa had a predisposition to MDS, a bone barrow disorder and blood cancer that often goes unrecognized and under-diagnosed, according to the MDS Foundation.

Then it was kind of a weird watching and waiting game, Taylor said. I think we all hoped it couldnt turn into this [MDS], but we knew it could.

Low-risk patients who do not receive a bone marrow transplant face an average survival rate of up to six years, according to the MDS Foundation. High-risk patients face as little as five months.

Taylor said she braced herself for the possibility that her mother would need a bone marrow transplant at some point. Each December, her mother would undergo a checkup with her oncologist.

Taylor examined her mothers lab work after the December 2019 appointment and could see the results were abnormal. The family had booked a cruise around Christmastime, so Taylor reached out to her mothers oncologist to see if it would be safe to travel.

Dr. Roboz gave them the OK and said theyd deal with it when they returned.

We went on this cruise and I didnt know anything, Ms. LaRosa said. My husband didnt know anything, but my daughter had all this information. She had some emotional moments on the cruise. Now, looking back, I know why.

Taylor recalled the trip to the Bahamas like something out of a movie, where nothing went wrong.

It was like a perfect trip, she said.

When Ms. LaRosa returned to her doctor for a follow-up, the reality of the situation set in. Dr. Roboz referred her to Dr. Tsiporah Shore, who has expertise in bone marrow transplants, at Weill Cornell Medicine. They met on March 14, 2020.

She basically said we need to do this right away, Ms. LaRosa said. Things were really progressing.

Ms. Lappe could see her sisters health was declining.

Nothing they did was making her better and I know this was something she dreaded doing, she said.

Before determining who would be the match, Ms. Lappe said she underwent the most extensive testing of her life. To find a match, doctors analyze the patients tissue type, specifically the human leukocyte antigen, or HLA, tissue, the proteins found on most cells in the body, according to the nonprofit organization Be the Match.

Finding the match is just the initial step in assuring that the donor is suitable for the transplant and there are no other potential ailments that could be passed on.

Ms. Lappe had assumed her brother Jason would be the pick since she had an autoimmune disease and he did not. When she found out she had been selected, it coincided with the early stage of the pandemic. That added another layer of stress, since Ms. Lappe knew if she came down with the virus, it could upend the entire process.

Other questions loomed over her.

Youre worrying, is my body going to do what it needs to do? Is it going to work? Will her body reject it? she said.

To begin the donation last July, Ms. Lappe received injections to increase her white blood cell count. At the same time, her sister was undergoing radiation and chemotherapy to essentially wipe her immune system clear, eliminating a lifetime of protections that had been built up.

Ms. Lappe said she had been warned shed feel pain in her bones from the shots. When she didnt feel anything after the first shot, she worried it might not be working.

By the third and fourth shot, there was no mistaking the odd sensation.

You have these bone pains, she said. Ive never had that happen.

On the fifth day, the doctors did a blood test as the final determination to begin the donation process.

To read more about bone marrow donation, visit BeTheMatch.org.

The procedure, called peripheral blood stem cell donation, required Ms. Lappe to be connected to a machine for six hours as blood was removed via a port in her chest to separate out the blood-forming cells. The remaining blood circulated back into her body.

At the end of it, one bag of the pinkish liquid that would be used to save her sister had been accumulated.

I said to her afterwards, it was so emotional, Ms. Lappe said, adding that she knew she would feel an overwhelming sense of guilt if the procedure didnt work.

She took a picture of the bag and its label, which read, Donor: Jennifer Lappe and Recipient: Lorraine LaRosa. She texted the picture to her sister and said, Oh, my gosh.

Ms. Lappe finished her donation on a Wednesday and her sister began to receive her bone marrow the next morning, once the doctors had determined they had a sufficient number of stem cells to start the process.

Then the waiting game began.

The day of a transplant is Day Zero. Every day afterward continues an upward count toward engraftment, when the blood-forming cells received during the transplant begin to grow and create healthy blood cells.

I would say those days were the hardest, just waiting, Taylor said. They would draw her labs every morning at 4 a.m. and the results would be back at 6 a.m.

A nurse would write the number on a board, and for several days it remained at zero. To pass the time, Ms. LaRosa would play games like Yahtzee with her husband, Mark, who commuted each day into the city. Taylor would watch Netflix shows like Jane the Virgin with her mom. The days were largely a blur for Ms. LaRosa.

Taylor knew it could take one to two weeks for engraftment to begin. It was Day 11 when they saw the first sign of hope as a nurse wrote .1 on the board, signaling the first sign of growth.

I remember that day being like a huge relief and huge turn, Taylor said.

Ms. LaRosa spent over a month in the hospital for close monitoring as her counts continued to climb. Even after she was released, she had to stay at a nearby hotel for another week because of daily checkups. She set her sights on Day 100, another milestone moment in the recovery.

If you make past Day 100, its a good thing, she said.

Even after a successful procedure with a 100% match, theres never a moment of being entirely in the clear. Ms. LaRosa will continue to be monitored for the rest of her life and setbacks are always possible. Shes faced one setback already, with graft vs. host disease, which can be common after a bone marrow transplant. Shes also endured blood clots.

But the biggest thing is that shes now clear of MDS and feeling better than before the procedure. She still, however, faces residual effects from chemotherapy. Shes often tired.

When she returned home, she mostly stayed inside, unable to venture out with the threat of COVID-19 still hanging over everything. Her immune system was rebuilding from scratch. She remains on a special diet. She cant have plants in the house, which put her at risk of exposure to pathogens that can cause disease. She cant have alcohol.

I said, God, I really want a glass of wine, Ms. LaRosa said with a laugh.

Taylor said there are constant signs of progress. Her mother just recently had a port removed from her chest wall after close to nine months. She received her COVID-19 vaccine. Her hair is growing back.

Shes starting to like the style, Taylor said.

She looks forward to the next steps of returning to normal: going to a movie theater and eating dinner at their favorite restaurant, Grana in Jamesport. When they sit together and toast their wine glasses, Taylor said she knows shell cry. They have always shared a close bond, particularly since Taylor was adopted at around 3 months old after her mother endured years of infertility issues.

Shes been my best friend and my rock for my whole life, Taylor said.

Bone Marrow Stem Cells Comments Off on Stem Cell Therapy Market worth $401 million by 2026 – Exclusive Report by MarketsandMarkets – PRNewswire | May 3rd, 2021

Bone marrow aspiration and trephine biopsy are usually performed on the back of the hipbone, or posterior iliac crest. An aspirate can also be obtained from the sternum (breastbone). For the sternal aspirate, the patient lies on their back, with a pillow under the shoulder to raise the chest. A trephine biopsy should never be performed on the sternum, due to the risk of injury to blood vessels, lungs or the heart.

The need to selectively isolate and concentrate selective cells, such as mononuclear cells, allogeneic cancer cells, T cells and others, is driving the market. Over 30,000 bone marrow transplants occur every year. The explosive growth of stem cells therapies represents the largest growth opportunity for bone marrow processing systems.

THE FAMILY of a nine-year-old leukaemia patient have been given 10 days to raise funds for life-saving treatment.

Nathaniel Nabenas family are appealing as he "clings on to life" after they were told they have until May 12 to find 201,000 for a stem cell transplant.

2

Without the operation, his cancer will be terminal.

Nathaniel is not entitled to free NHS treatment because he is not a British national.

He flew to the UK to have a 5,000 prosthetic eye fitted privately after losing it to a tumour in his home country Nigeria.

Doctors at Londons Great Ormond Street Hospital, moved by Nathaniels plight, have revealed they have waived their private consultant fees to help.

And Paul OGrady, who presents ITV series Little Heroes at the childrens hospital, has voiced his support.

It was only when he arrived here in November that doctors discovered he had acute myeloid leukaemia, a cancer so aggressive that he could have died within weeks without chemotherapy.

A stem cell match has been found but the family now have to find 201,103.

This money goes to the NHS for the cost of the transplant, treatment and after-care, based on a typical in-patient admission of eight weeks and a three-month follow-up as an outpatient.

2

Nathaniels cancer is in remission after six rounds of chemo but his consultant says it could return at any time.

If they raise enough, then a transplant will go ahead after tests due to take place on May 14.

Parents Ebisidor, a business analyst, and wife Modupe, 38, who are staying with family in Croydon, South London, were initially told the hospital bill could be as much as 825,000.

Ebisidor, 45, told the Mirror: Weve seen a dramatic turnaround from the hopeless situation we were in six months ago and we cant thank Sunday People readers enough.

Its incredible that the doctors are treating him in their private work without charging. They are wonderful. We are so grateful to everyone for giving us hope but at the same time asking people to help Nathaniel cling on to life. We know its a lot to ask.

Professor Ajay Vora, a consultant paediatric haematologist at GOSH, said the superhero fan had been incredibly brave.

But he warned: The cancer could come back at any time and the longer we wait the more likely it will return. Then Nathaniel will only have the option of palliative care.

"The tests we are doing in two weeks will reassure us it hasnt started to come back before we give him the transplant.

Prof Vora added: All the consultants involved in his care are working in a private capacity and have waived their fee because they want to help him.

Our time is not borrowed from the NHS because we are treating Nathaniel in our private service in our time.

Doctors had hoped Nathaniel would be able to have a bone marrow transplant from one of his two sisters Nadia, 11, and Nicole, 21 months. But they were not a match.

Instead, stem cells from a stored umbilical cord will be used to save him.

Doctors will give Nathaniel high doses of chemotherapy to kill off his stem cells and replace them with healthy ones.

Dad Ebisidor said: The faster we can do this transplant the more chance Nathaniel has of survival.

"We dont have this sort of treatment back home. We didnt bring him to the UK sick. He got poorly while he was here. If the operation doesnt work our only option will be to take him to a hospice.

By law, non-UK residents get free emergency care but are charged for operations if they are admitted to hospital.

They pay for treatment at 150% of the NHS national tariff the cost normally incurred for eligible patients.

A Great Ormond Street spokesman said: Nathaniel has responded well to treatment, with our clinical teams working to provide the best care for him including looking at taking advantage of the short window of time for receiving a transplant.

Desperate family of boy, 9, with leukaemia have 10 days to save his life... - The Sun

Bone Marrow Stem Cells Comments Off on Desperate family of boy, 9, with leukaemia have 10 days to save his life… – The Sun | May 3rd, 2021

Cell and gene therapies are overlapping fields of research and treatments. While both aim to treat and potentially cure diseases, they have slightly differing approaches and have different historical backgrounds. Due to growing interest surrounding this field, the general public still has much to learn and understand about each of these potentially life-saving therapies.

Below, we provide a general overview and brief historical context for each type of therapy.

Cell therapyis the process of replacing damaged or dysfunctional cells with new, healthy ones by transferring live cells into a patient. These can be autologous (also known as self-to-self, using cells from the patient receiving the treatment) or allogeneic (using cells from a donor for the treatment). While this field of treatment has recently begun to expand, some forms of cell therapy like the cancer-treating hematopoietic stem cell transplantation(HSCT) have been in practice for decades.

While many people have heard of bone marrow transplants, few realize that this procedure is a stem cell therapy. While stem cells can be derived from many sources, such as umbilical cord blood and mobilized peripheral blood, bone marrow derived stem cell therapy is the most commonly used today and has been for more than 50 years.

The first transfusion of human bone marrow was given to a patient with aplastic anemia in 1939. After World War II researchers diligently worked to restore bone marrow function in aplasia patients caused by exposure to radiation produced by the atomic bomb. After a decade of work they were able to show, in a mouse model, that aplasia could be overcome by bone marrow treatment.

The first allogeneic HSCT, which led the way to current protocols, was pioneered by E. Donnall Thomas and his team at the Fred Hutchinson Cancer Research Center and reported in the New England Journal of Medicine in 1957. In this study six patients were treated with radiation and chemotherapy and then received intravenous infusion of bone marrow rich stem cells from a normal donor to reestablish the damaged or defective cells. Since then the field has evolved and expanded worldwide. While almost half of HSCT are allogeneic, the majority of HSCT are autologous, the patient's own stem cells are used for treatment, which carries less risk to the patient.

In 1988, scientists discovered that they could derive stem cells from human embryos and grow the cells in a laboratory. These newly derived stem cells, referred to as embryonic stem cells (hESCs), were found to be pluripotent, meaning they can give rise to virtually any other type of cell in the body. This versatility allows hESCs cells to potentially regenerate or repair diseased tissue and organs. Two decades after they were discovered, treatments based on hESCs have been slow in coming because of controversy over their source and concerns that they could turn into tumours once implanted. Only recently, testing has begun as a treatment for two major diseases: heart failure and type 1 diabetes.

In 2006, researchers made a groundbreaking discovery by identifying conditions that would allow some cells to be 'reprogrammed' genetically. This new type of stem cell became known as induced pluripotent stem cells (iPSCs). Since this discovery, the field has expanded tremendously in the past two decades. Stem cell therapies have expanded in use and have been used to treat diseases such as type 1 diabetes, Parkinson's and even spinal cord injuries.

There has also been a growing focus on using other immune cells to treat cancer. Therapies such as CAR T-cellare dependent upon a patient's T-cells, which play a critical role in managing the immune response and killing cells affected by harmful pathogens. These cells are then reengineered to target and kill certain cancerous cells. Several CAR T-cell therapies have been FDA approved, with the first approval being given in 2017 for Yescarta and Kymriah, to be used for the treatment of B-cell leukemia in children and young adults.

Gene therapyis a process that modifies the expression of a gene or alters the biological process of living cells for therapeutic use. This process can take the form of replacing a disease-causing gene with a new, healthy one, inactivating the mutated gene, or introducing a new gene to help the patient's body fight a disease.

While the use of gene therapy to treat humans is fairly new, the science behind it has been used in science for decades. Farmers and geneticists have collaborated for years on crop improvement using cross pollination, genetic engineering and microinjection techniques to create stronger, more resilient crops.

The first human patient to be treated with gene therapy was a four-year old girlsuffering from severe combined immunodeficiencyin 1990. She received treatment for a congenital disease called adenosine deaminase (ADA). Since then, gene therapies have been used to treat diseases such as cancer, cystic fibrosis and hemophilia.In 2017, the FDA gave its first approval of a gene therapy called Luxturna, which is used to treat patients with established genetic vision loss that may result in blindness. Gene therapies are still being studied and developed, with over 1,000 clinical trialscurrently underway.

LCol Laura Laycock on deployment.

LCol Laura Laycock

It was Oct. 7, 2019, and life was not just good, it was amazing.

My career in the Royal Canadian Air Force was going great. I loved my job and was getting promoted. Throughout my Canadian Armed Forces career of over 20years, I had represented Canada around the world with NORAD, NATO and the UN. I had married the most incredible man. We relocated to Ottawa, started to travel the world together, and were ready to start a family.

Then, on Oct. 8, 2019, everything changed.

I was diagnosed with Chronic Myeloid Leukemia(CML) after blood work for vertigo showed extremely elevated white blood cell counts. CML is a blood cancer where the bone marrow overproduces white blood cells, which eventually impairs the development of white and red blood cells and platelets. Its usually caused by a spontaneous mutation in DNA, which contains our genetic code.

LCol Laycock

Twenty years ago, researchers developed a new line of drugs that combat this overproduction of white blood cells. These targeted oral chemotherapy pills have been revolutionary in the fight against CML. Most people who take them do so for the rest of their lives and have good survival rates; however, a stem cell transplant remains the only actual cure. But its risky and not needed for most people.

Its now been about 17months since my diagnosis and my body has not tolerated this targeted chemotherapy. I fall into that small fraction of people who get debilitating or life-threatening side effects from this medication. My doctors are discussing other treatment options, one of which is a stem cell transplant, but my mixed ethnicity (European/Middle Eastern) has made it difficult to find a donor match.

My journey since my diagnosis has been to slow down and educate myself so that I can heal and advocate for my care; to appreciate every little moment of joy; and to do my best to overcome each challenge that arises. I have found strength in the extraordinary support Ive received from my family, my friends and my community, both old and new.

With the help of family and friends, I recently began a social media campaign to increase stem cell donor education and registration in Canada and around the world. Many people are unaware of the potentially lifesaving role they can play by registering to become stem cell donors. Stem cell transplants are vital treatment options for people with a range of medical conditions including spinal cord injuries, heart disease, diabetes, and some cancers.

The process to donate is simple. First, you register online with Canadian Blood Services or Hma-Qubec and do a mail-in cheek swab., and then you wait. It could be months or years before you are identified as a match. During this waiting period, you should update your contact information with the registry if it changes.

When you are matched, you will be contacted to continue with the donation process. This process is similar to giving blood, but it has its differences. The cells are usually collected intravenously from peripheral blood in a non-surgical procedure but, in rare cases, they are collected directly from the bone marrow in a surgical procedure. In either case, the risks associated with donating are minor.

In Canada, individuals aged17 to 35 can register to become stem cell donors (ages18 to 35 in Quebec). Both CBS and Hma-Qubec are part of an international network of donor registries from over 50countries. This network has a pool of over 38million donors but, unfortunately, matches are rare.

Your stem cells could potentially help others around the world, and throughout this process donor privacy is assured at all times.

LCol Laycock on her wedding day.

Stem cell matching relies on Human Leukocyte Antigen typing, which is highly influenced by ethnicity. This means that a patients best chance of finding a matching donor is from those who share similar ethnic backgrounds. Research conducted by Gragert et al.(2014) has shown that the likelihood of finding a match for certain ethnic groups can be as low as 16 percent and as high as 75 percent for others. This disparity highlights the need for more ethnically diverse stem cell donors in our registries.

Today, I am calling on my DND and CAF families to register as stem cell donors to help people, like me, who are fighting for our lives. If you arent able to register, please share this call with those who can. You, or someone you know, could be the match that saves a life a simple swab is all it takes to be a hero.

Children and young adults who underwent an allogeneic hematopoietic stem cell transplant (alloHSCT) after achieving complete response with CD19 CAR T-cell therapy experienced durable B-cell acute lymphoblastic leukemia (B-ALL) control, according to the results of a phase 1 trial (ClinicalTrials.gov Identifier: NCT01593696) published in the Journal of Clinical Oncology.

Although a proportion of patients who undergo CAR T-cell therapy go on to receive alloHSCT, the study authors stated that The role for [alloHSCT] following CD19-CAR T-cell therapy to improve long-term outcomes in [children and young adults] has not been examined.

The phase 1 trial evaluated 50 children and young adults with B-ALL who received CD19.28 CAR T-cell therapy. The primary objective was to determine the maximum tolerated dose of CAR T cells, toxicity, and feasibility of generating CAR T cells in the study population. In addition, this analysis retrospectively evaluated the effect of alloHSCT on survival after CAR T-cell therapy.

At baseline, the median age was 13.5 years (range, 4.3-30.4), and 40 (80%) of the patients were male. The median number of prior regimens was 4 (range, 4.3-30.4); 22 (44%) patients had at least 1 prior HSCT, 2 (4%) had prior CD19-targeted therapy, and 5 (10%) of the patients had prior treatment with blinatumomab.

Complete response was achieved in 31 (62%) of the patients. Among these patients, 28 (90.3%) were negative for minimal residual disease. Higher rates of complete response were associated with primary refractory disease, fewer prior lines of therapy, M1 marrow, or fludarabine/cytarabine-based lymphodepletion. The median overall survival was 10.5 months (95% CI, 6.3-29.2) during a median follow-up of 4.8 years.

Of the 28 patients who achieved complete response, 21 (75%) proceeded to undergo consolidative alloHSCT. The median overall survival for these patients was 70.2 months (95% CI, 10.4-not estimable), with an event-free survival not yet reached. The rate of relapse after alloHSCT was 4.8% (95% CI, 0.3-20.3) at 12 months and 9.5% (95% CI, 1.5-26.8) at 24 months.

Any grade cytokine release syndrome (CRS) developed among 35 (70%) patients, with 9 (18%) experiencing grade 3 to 4 CRS. Of the 10 patients (20%) who developed neurotoxicity, 4 cases were severe. One cardiac arrest occurred during CRS. All patients with CRS, neurotoxicity, and cardiac arrest recovered.

The authors concluded that CD19.28 CAR T cells followed by a consolidative alloHSCT can provide long-term durable disease control in [children and young adults] with relapsed or refractory B-ALL.

Kaytlyn Gerbin, left, runs the Wonderland Trail around Mount Rainier. She completed the 93-mile loop in just under 19 hours. Her friend Tara Fraga helped with pacing between miles 30-55. (Ryan Thrower Photo)

When Kaytlyn Gerbin moved to Seattle 10 years ago to attend graduate school at the University of Washington, a friend took her to Kerry Park in the Queen Anne neighborhood on her first visit. The celebrated viewpoint offered Gerbin a glimpse of Mount Rainier that ignited an ongoing passion.

At the time, I had absolutely no idea there was a trail all the way around it, and didnt know the first thing that went into climbing to the summit or running even a few miles on the trails, Gerbin said. Since then, Ive climbed Rainier 10 times, and spent countless hours on the mountain and trails in that park.

Along with her drive to get to know Washington states most famous landmark more intimately, Gerbin achieved her PhD in bioengineering at UW, where her research was focused on the therapeutic and regenerative potential of cardiac cells. For the past four years shes been a scientist at Allen Institute for Cell Science, where she studies stem cells and cardiomyocytes, or cardiac muscle cells.

Our latest Geek of the Week, Gerbin is an accomplished ultrarunner, and she now knows a lot more about that trail that encircles Mount Rainier.

With COVID-19 lockdowns impacting her international race season last summer, Gerbin, a sponsored athlete for The North Face, went after the fastest known time, or FKT, for a run around the Wonderland Trail. Together with teammate Dylan Bowman of Portland and a small crew of local filmmakers, they made Summer of Wonder, a short film about the experience, which you can watch in full here:

The average thru-hiker takes 10-14 days to complete the 93-mile Wonderland Trail, with its 24,000 feet of elevation gain. Gerbin did it in 18 hours, 41 minutes, 53 seconds, and the film is a breathtaking look at her endurance feat.

Gerbins passion for running started with 3-mile commutes back and forth between her apartment, her research lab, and campus during grad school. Eventually she started trail running,essentially as a life hack to see if she could squeeze a five-day backpacking route into a weekend between experiments.

It turned out I was actually pretty good at that, and that opened up opportunities to start racing at some of the most competitive trail races in the U.S. and Europe, Gerbin said.

Shes since raced with Team USA at the Trail World Championships, reached the podium at the iconic Western States 100, and won races such as the Canary Islands Transgrancanaria and Cascade Crest 100 in Washington. She also still holds the womens self-supported FKT for the Rainier Infinity Loop (set in 2019), which combines the Wonderland Trail with two summits and descents of Mount Rainier.

Her preferred racing distance is anything between 50-100 miles long, the more elevation gain and technical the trail, the better. During peak training, Gerbin is usually hitting between 70-90 miles with over 20,000 feet of elevation gain each week. She calls the Pacific Northwest the best outdoor playground there is.

Although I love running fast, Im also really excited about pushing myself on more challenging terrain. So many of my other FKT goals and route ideas are along these lines, with more technical traveling than actual running, she said.

COVID permitting, her highest race priority this year is Ultra Trail du Mont Blanc, which is the most competitive world-stage for ultrarunning, at the end of August. The race circumnavigates Mont Blanc, passing through France, Italy, and Switzerland and covering around 105 miles and 33,000 feet of elevation gain.

While Gerbins experience as a scientist does inform her appreciation for what shes putting her body through during ultrarunning, shes equally passionate in the lab. At the Allen Institute shes seeking answers to broad questions about how cells work, including how single cells and all of their components are integrated into a functional system, while using imaging to build predictive models of cell behavior.

I get the opportunity to work with a multidisciplinary team of badass scientists, biologists, and engineers on really cool problems in cell biology, she said.

Learn more about our latest Geek of the Week, Kaytlyn Gerbin:

What do you do, and why do you do it? Science and ultrarunning for me have always come down to problem solving.

As a scientist, problem solving is inherent to experimental design, data analysis, and interpreting results. By asking hard questions, Im interested in pushing the field of cell biology forward, and challenging the current way of thinking.

As an ultrarunner, its a different kind of problem solving, but I lean on the same mindset to figure out how to push my athletic limits further and faster.

One thing that always amazes me is how adaptable the human body is. My training in cell science gives me context for how all of these stressors and inputs were putting on our bodies are fundamentally happening at the single cell level, and it keeps me thinking about the cells response to external cues in my research.

Whats the single most important thing people should know about your field? Yes, I do think about science and when Im running, and no, I do not geek out on heart rate monitors and training zones and all those numbers when Im running.

Where do you find your inspiration? Im inspired by brilliant women that are pushing whats possible in both science and in sports. I think we often set boundaries for ourselves about what we think is possible, without ever letting ourselves really hit that limit. Im inspired by women who set bold goals and bring others up and along for the ride, redefining whats possible.

Whats the one piece of technology you couldnt live without, and why? My Garmin 935. I use this watch daily to track miles run, elevation gain, etc. The battery life has lasted me for 100 miles of running and ~24 hrs, but its small enough to wear every day.

Whats your workspace like, and why does it work for you? Prior to 2020, I was splitting my time between the tissue culture hood (passaging cells, differentiating cardiomyocytes, setting up experiments), conference rooms (team science and collaboration means a lot of group discussions!), and my computer for writing and analysis. Since then, Ive shifted my work to be more remote while I work on a few different manuscripts. I have an office set up at home with a window, some good tunes, plenty of coffee, and a chair for my dog to wait impatiently on.

Your best tip or trick for managing everyday work and life. (Help us out, we need it.) I have always been a to-do list person. Most mornings start with me listing out tasks (and breaking those down into many sub-tasks). I feel productive as I cross things off, and it also helps me prioritize and plan ahead to make sure I can also fit my training runs in.

Mac, Windows or Linux? Mac as a personal preference, Windows for my work computer (I do work at the Paul Allen Institute 🙂

Transporter, Time Machine or Cloak of Invisibility? Transporter. I just promise not to use it in races.

Greatest game in history: Lode Runner. I havent played it since I was a kid, but the memories of yelling at the computer with my sister frantically hitting up-down-up-down arrows make me feel like it was just yesterday.

Best gadget ever: Garmin inReach mini satellite messaging and SOS call, all in a device small enough to throw in the bottom of a pack (or shorts pocket) and forget its there. I bring this with me anytime Im headed out into the wilderness/mountains, but I hope I never need to use it.

First computer: iMac G3.

Current phone: iPhone 11.

Favorite app: I have a love/hate relationship with Strava. Ive also been using DuoLingo during the pandemic and have a strong daily streak going!

Most important technology of 2021: COVID vaccines!!

Most important technology of 2023: Advancements in remote/low-resource medical care.

Final words of advice for your fellow geeks: Most problems can be solved with more snacks and some time (works for science and running).

Kaytlyn Gerbin is blazing trails in cell science and as an ultrarunner who has conquered Mount Rainier - GeekWire

Cardiac Stem Cells Comments Off on Kaytlyn Gerbin is blazing trails in cell science and as an ultrarunner who has conquered Mount Rainier – GeekWire | April 19th, 2021

By Guest Blogger Rich Whittle, Bioastronautics & Human Performance Lab at Texas A&M UniversityThe recent landing of the probe Perseverance on Mars, and the excitement generated by the high-resolution images currently being broadcast back to Earth, has inevitably started people thinking about human exploration of the Red Planet. However, the challenges faced by a manned journey to Mars are much more than just technical, but reflect some fundamental aspects of human physiology. In this guest article, Rich Whittle of the Bioastronautics and Human Performance Lab at Texas A&M University, reflects on some of the key issues.

NASA has ambitious plans to begin manned exploration of Mars, although its current focus is on sending the next man and first woman to the Moon as part of the Artemis programme, which will establish a permanent human presence there in the coming decade. A key part of this latter objective is to place a spaceship called Gateway in orbit around the Moon, from which landers will take astronauts to the surface and support their activities. Gateway will also conduct a wide variety of human and scientific missions, and in particular study the physiological effects of long journeys into space, in preparation for that first manned voyage to Mars.

The human body has evolved over hundreds of thousands of years to flourish on the surface of the Earth, and it is perhaps not surprising that the stresses of spaceflight pose unique physiological and medical problems. In fact, many of the basic issues associated with spaceflight, such as hypoxia, dysbarism, acceleration, and thermal support, have been well studied through aviation and diving medicine in the years prior to spaceflight. But while the last 50 years of manned space exploration have shown that humans can adapt to space, remaining productive for up to 1 year and possibly longer, there are still many problems associated with the prolonged exposure to a unique combination of stressful stimuli including acceleration, radiation, and weightlessness. The latter condition is a critical feature of spaceflight and has significant effects on human physiology, many of which were quite unexpected at the beginning of space exploration.

Scientists have known for a long time that the human body responds in specific ways to the microgravity environment of spaceflight. For example, a person who is inactive for an extended period loses overall strength, as well as muscle and bone mass. Unsurprisingly spaceflight has a similar effect, resulting in loss of bone mineral density (BMD), and increasing the risk of bone fractures in astronauts. It is predicted that a third of astronauts will be at risk for osteoporosis during a predicted 7-month long human mission to Mars. It is however possible to compensate for this loss of muscle and bone mass using resistive exercise devices that NASA has developed to allow for more intense workouts in zero gravity.

Overall, the pathophysiological adaptive changes that occur during spaceflight, even in well-trained, highly selected, and healthy individuals, have been likened to an accelerated aging process, and are being studied in research groups around the world. My own research at Texas A&M focuses on changes to the cardiovascular system caused by the microgravity environment of spaceflight. In an upright position under the Earths standard 1G gravity, arterial blood pressure is lower above the heart and higher below the heart. But in a weightless environment the body experiences a uniform arterial pressure, which decreases the cardiac workload, and reduces the need for blood pressure regulatory mechanisms. As a result, the muscles of the heart and blood vessels begin to atrophy, and consequently some astronauts experience orthostatic intolerance, the difficulty or inability to stand because of light headedness after return to Earth. During spaceflight, cardiovascular changes are noticeable immediately after the onset of weightlessness, with astronauts exhibiting characteristically puffy faces, stuffed noses, and chicken legs, as approximately 2L of fluid is shifted from the legs towards the head.

These fluid shifts affect not only the cardiovascular system but also the brain, eyes, and other neurological functions. The apparent increase in fluid within the skull is potentially linked to a collection of pathologies of the eye known as Spaceflight Associated Neuro-ocular Syndrome (SANS). This is principally manifested through a hyperopic shift in visual acuity, which in some cases does not resolve on return to Earth.

We believe that many of these problems can be overcome through effective countermeasures during spaceflight, and are often reversible after landing. Physical exercise programs are the main countermeasure used during spaceflight to protect the cardiovascular system. The technology involved has advanced from a rowing ergometer used in the early Skylab missions, through a motorized treadmill used in the ISS. This has been recently joined by a device for performing resistive exercise, and now rowing ergometers are once again being looked at for longer duration missions to Mars due to their small footprint.

However, some astronauts have returned from the ISS with unexpectedly stiff arteries, of a magnitude expected from 10 20 years of normal aging. Arterial stiffening is often linked to an increased blood pressure and elevated risk for cardiovascular disease. Additionally, other studies have suggested that insulin resistance occurs during spaceflight, possibly due to reduced physical activity, which could lead to increased blood sugar and increased risk of developing type 2 diabetes. These results suggest that the astronauts exercise routine did not always counteract the effect of the microgravity environment and indicated that further countermeasures might be needed to help maintain astronaut health. Here at Texas A&M we are looking at both lower body negative pressure (LBNP) and artificial gravity generated through short radius centrifugation as exciting new countermeasures that could be used in long duration spaceflight.

As we begin to further understand the effects of spaceflight on human physiology, scientists are now starting to study some of the underlying cellular mechanisms using model organisms, cell cultures, organs on a chip and stem cells. And because many of the observed changes seen in space, such as cardiovascular dysfunction due to inflammation, lack of exercise, intracranial hypertension, and hormonal and metabolic changes, resemble those caused by aging or illnesses, the research we conduct may have important applications on Earth. Hopefully, our push for manned exploration of the planets of the solar system will lead to tangible benefits to the health and well-being of humans on our home planet.

The Physiological Challenges of Spaceflight - Cambridge Wireless

Cardiac Stem Cells Comments Off on The Physiological Challenges of Spaceflight – Cambridge Wireless | April 19th, 2021

The 1997 film Gattaca promised a future where humans would be free of disease and babies born on demand with the latest upgrades, including enhanced speed, intelligence, and beauty. Much like a new Tesla Roadster. However, despite the technological predictions offered by Hollywood moviemakers, were still living in a time when synthetic biology is working hard to make a dent in the world. No designer babies in sight. And stem cell technology promised so many radical breakthroughs back in the late 1990s, including growing organs for transplants and regenerating whole body parts, but the challenge of growing whole organs has been shown to be more complex than previously believed, including technologies like 3D bioprinting and xenotransplantation.

Despite the challenges and setbacks, investors believe were living in a different time, with more money pouring into the space over the last few years:

Indeed, the science and technology behind manipulating biological matter are still promising when it comes to health and medicine, especially with the rise of CRISPR gene editing. The idea that we could potentially switch on or off genes that cause disease using a cocktail of enzymes is just fantastical. While inserting CRISPR enzymes into a live human being is a bit challenging, there are regions of the body that are easily accessible, such as the eye. In a landmark clinical trial approved by the FDA and led by Editas Medicine (EDIT) and Allergan, now owned by AbbVie (ABBV), a CRISPR-Cas9 gene therapy was administered directly to patients to remove rare mutations that can cause childhood blindness.

McKinsey is calling this emerging technological renaissance the next Bio Revolution, with advances in biological sciences being accelerated by automation and artificial intelligence. The speed at which scientists and researchers were able to sequence the genome of the Rona virus is a testament to the power of these converging technologies. McKinsey predicts that synthetic biology could have a direct economic impact of $4 trillion per year, nearly half of which will be in the domain of human health.

Lets take a look through five companies that are harnessingthe revolutionary power of synthetic biology to design new therapies and treathuman diseases.

Founded in 2017 and headquartered in Alameda, California, Scribe Therapeutics is a biotechnology startup that is producing therapeutics using custom-engineered CRISPR enzyme technology. The company has raised a whopping $120 million from the likes of Andreessen Horowitz to build out a suite of CRISPR technologies designed to treat genetic diseases. Scribe Therapeutics was co-founded by Dr. Jennifer Doudna, the UC Berkeley biochemist who discovered and developed CRISPR gene-editing technology and won the Nobel Prize in Chemistry in 2020 for her pioneering work.

The team at Scribe Therapeutics has designed its XEditing (XE) technology by evolving the native CRISPR gene-editing enzymes available to us to redesign and engineer them to suit different needs. More specifically, they want to be able to modify or silence the genes of live humans to treat genetic diseases such as Huntingtons, Parkinsons, Sickle Cell Anemia, and Amyotrophic Lateral Sclerosis (ALS). Anything your parents unwittingly handed down to you, Scribe Therapeutics is looking to treat it. The research team tests thousands of redesigned enzymes and selects those with greater editing ability, specificity, and stability compared to current enzymes. Scribe Therapeutics is starting with a pipeline of therapeutics to treat neurodegenerative diseases and has its sights set on other, less common genetic conditions down the road.

Canadian biotechnology startup Notch Therapeutics was founded in 2018 and has raised $86 million to develop immune cell therapies against pre-cancer cells. The companys cell therapies are based on induced pluripotent stem cells (iPSC), which are pre-differentiated cells with the limited capacity to transform into different mature cell lines. Based on its Engineered Thymic Niche (ETN) platform, the company is developing universally compatible stem cell-derived immune cell therapies.

Normally, human immune cells only recognize othercells found in the same individual and will target cells from other individuals,which appear foreign to the immune system. Thats why donor organs can sometimesbe rejected by the recipients body the immune system sees the organ as a foreignobject. Notch Therapeutics is designing a system where the immune cellsproduced from the stem cells will be universally recognizable by allindividuals, bypassing the need to create immune cells from pluripotent stemcells derived from each recipient. These manufactured immune cells, whichinclude T cells or natural killer cells, can be programmed to target cancercells and eliminate them from the patient.

Founded in 2016, Massachusetts-based bit.bio is a synthetic biology startup thats working on merging the world of coding with biology. The company has secured $42 million after a Series A round that was completed in June 2020. A spinout of Cambridge University, bit.bio is looking to commercialize its proprietary platform, opti-ox, which can reprogram human stem cells to do its bidding cure diseases. Touted as the Cell Coding Company, bit.bio was founded by Dr. Mark Kotter, a neurosurgeon at the University of Cambridge who studied regenerative medicine and stem cell technology.

While the ability to program mammalian stem cells has been around since 1981, the company claims it can consistently reprogram human adult cells into pluripotent stem cells, and then transform them into other mature human cells within days. Currently, stem cell technology produces a statistical mixed bag of mature, differentiated cells, some of which can have potential side effects. opti-ox uses a precise combination of transcription factors to ensure stem cells mature into cardiac, muscle, liver, kidney, or lung cells with high efficiency. The holy grail for the company is to be able to produce every cell in the human body for any cell therapy safely, on-demand, and with purities approaching 100%. And well be here, waiting for that stem cell therapy for erectile dysfunction promised by the medical community.

Founded in 2020, Delonix Bioworks is a Shanghai-based synthetic biology company designing therapeutic solutions against infectious diseases. The startup received $14 million from a Seed round just back in March. The Delonix Bioworks team is focusing its initial efforts on anti-microbial resistant (AMR) infections. The emergence of resistance in some bacteria species against common antimicrobial compounds, so has led to an increasing number of infections that are difficult to treat with conventional strategies. These superbug strains are mostly spread in hospital or clinical settings due to the overuse of antibiotics.

The company is engineering attenuated, live bacteria thatcan act as vaccines against these types of infections. By introducing reprogrammed,but weakened, bacteria to express specific antigens on the surface of theirmembrane that match those of the strains that cause AMR infections into anindividual, the individuals immune system can recognize those antigens andrespond to future infections with greater speed. Its no different from how antiviralvaccines are designed, except most vaccines introduce an attenuated or inactivatedvirus to activate the immune system instead. And for those of you who skipped highschool biology, no, this is not a mind-control scheme orchestrated by biotech companies.

Founded in 2018, Octarine Bio is a Danish synthetic biology company thats building out a pipeline for high-potency cannabinoids and psilocybin derivatives for the pharmaceutical industry. Octarine Bio has brought in $3 million after a Seed round that was also completed in March. Medical studies on psychotropic compounds have been shown to help reduce anxiety, depression, and pain, and may have the potential to serve as novel psychiatric medications. A few companies have recently emerged to commercialize existing psychedelics. Octarine Bio believes it can do better by harnessing the power of synthetic biology to engineer microorganisms to produce these psychotropic compounds with better pharmacokinetic and therapeutic effects.

Normally, natural products are produced by plant and fungal species as an ill-defined mixture. The psychoactive properties of these compounds primarily stem from only a handful of compounds because their natural concentration is much higher than other derivatives in the organic material. For example, tetrahydrocannabinol (THC) is the main psychoactive agent in marijuana while psilocybin is the one found in mushrooms from the Psilocybe and other psilocybin-producing genera. However, these are just a few out of hundreds of potential psychoactive derivatives produced by these species.

Molecular derivatives may be produced at too low of concentration to test and analyze, or the plant or mushroom may have a deactivated metabolic pathway that could lead to a superior compound. By tweaking the molecular structure of the product compounds using both synthetic biology and traditional organic chemistry, the team at Octarine Bio is creating a platform to discover new potential therapeutics that may not have been available before. Magic mushrooms are about to get an upgrade for an extra potent trip.

Much like what was said about software by Marc Andreessen back in 2011, synthetic biology is starting to eat the world. While were a long way away from a dystopian future where babies are engineered with supernatural talents, were already seeing the potential side-effects of using CRISPR on the Chinese twin girls originally to immunize them from HIV, including enhanced cognition and memory. The cure for stupid is possibly lurking in the vaults of this pioneering technology. For now, well wait and see how synthetic biology and CRISPR gene editing shape up as potential therapeutics for real diseases.

5 Novel Therapies Using Synthetic Biology - Nanalyze

Cardiac Stem Cells Comments Off on 5 Novel Therapies Using Synthetic Biology – Nanalyze | April 19th, 2021

Cut off a piece of a zebrafish heart, and the little creature wont be at the top of its game for a few days.

But after a month, the heart will grow back to normal and life goes on as normal.

Given that a heart attack in humans known as a myocardial infarction is akin to losing a piece of your heart (because tissue dies), scientists for years have been trying to understand how zebrafish heal themselves, with a view to replicating the process in people.

Now, scientists at the Victor Chang Cardiac Research Institute have identified the genetic switch in zebrafish that prompts heart cells to divide and multiply after a heart attack, resulting in the complete regeneration and healing of damaged heart muscle in these fish.

Dr Kazu Kikuchi, who led the research, published in Science on Friday, said he was astonished by the findings.

Our research has identified a secret switch that allows heart muscle cells to divide and multiply after the heart is injured, Dr Kikuchi said in a statement.

data-s="video/mp4">

It kicks in when needed and turns off when the heart is fully healed. In humans where damaged and scarred heart muscle cannot replace itself, this could be a game changer.

The researchers investigated a critical gene known as Klf1, which previously had only been identified in red blood cells.

They discovered Klf1 plays a vital role in healing damaged hearts.

The gene works by making uninjured heart muscle cells called cardiomyocytes more immature and changing their metabolic wiring, a process called dedifferentiation.

This allows them to divide and make new cells

Cardiomyocytes are the heart cells primarily involved in the contractile function of the heart that enables the pumping of blood around the body.

Ordinarily, adult mammalian hearts have a limited ability to generate new cardiomyocytes whereas zebrafish will keep making new cells until their hearts are completely healed.

Its been known for more than a decade that cardiomyocytes become more youthful in order to regenerate and Dr Kikuchi was one of the researchers to demonstrate this.

What wasnt known was how this was made to happen.

Our new paper suggests it is Klf1 which triggers this, Dr Kikuchi said.

This isnt the same as stem cell technology. In fact, dedifferentiating cardiomyocytes has proved to be a more effective healing process than stem cells.

It all comes down to that genetic switch.

Dr Kikuchi said that when the gene was removed, the zebrafish heart lost its ability to repair itself after an injury such as a heart attack, which pinpointed it as a crucial self-healing tool.

Professor Bob Graham, head of the Institutes Molecular Cardiology and Biophysics Division, says this world-first discovery made in collaboration with the Garvan Institute of Medical Research may well transform the treatment of heart attack patients and other heart diseases.

The team has been able to find this vitally important protein that swings into action after an event like a heart attack and supercharges the cells to heal damaged heart muscle. Its an incredible discovery, Professor Graham said.

The gene may also act as a switch in human hearts. We are now hoping further research into its function may provide us with a clue to turn on regeneration in human hearts, to improve their ability to pump blood around the body.

Importantly, the team also found the Klf1 gene played no role in the early development of the heart and that its regenerative properties were only switched on after a heart injury.

Synthego, the genome engineering company, today announced the launch of Eclipse, a new high-throughput cell engineering platform designed to accelerate drug discovery and validation by providing highly predictable CRISPR-engineered cells at scale through the integration of engineering, bioinformatics, and proprietary science. The launch of this unique CRISPR-based platform is driving the companys growing impact in biopharma R&D, reinforcing Synthegos position as the genome engineering leader.

CRISPR-engineered cells have a wide range of applications in research and development across disease areas, including in neuroscience and oncology. Synthego created the Eclipse Platform to enhance disease modeling, drug target identification and validation, and accelerate cell therapy manufacturing.

"By industrializing cell engineering, Synthegos Eclipse Platform will enable economies of scale, turning a historically complex process into one that is flexible, reliable, and affordable, said Bill Skarnes, Ph.D., professor and director of Cellular Engineering at The Jackson Laboratory and Synthego advisory board member. Offering CRISPR edits at scale, similar to what Synthego did with sgRNA reagents, puts researchers on the cusp of being able to study thousands of genes, and examine hundreds of variants of those genes. This will allow scientists to more faithfully model the complexity of a human disease, which could lead to the development of therapeutic drugs or next-generation gene therapies for many serious diseases.

To ensure the success of any type of edit, Eclipse uses machine learning to apply experience from several hundred thousand genome edits across hundreds of cell types. With this machine learning, combined with automation, the new platform can reduce costs and increase the scalability of engineered cell production. The Eclipse Platform is modular in design, allowing for fast deployment of upgrades or add-ons. It is engineered to use a cell-type agnostic process and immediately benefit researchers working with induced pluripotent stem (iPS) cells and immortalized cell lines.

We are living in a new era of life sciences innovation one that has added to DNA sequencing and being able to read out of biology, now being able to write into and engineer biology. We created our Eclipse Platform at the convergence of science and technology to make genome editing more precise, scalable, and accessible, said Paul Dabrowski, CEO and co-founder of Synthego. We are excited to expand our impact on advancing the life sciences innovation with the launch of this unique CRISPR-based platform.

Google is discontinuing the Google Play Movies and TV app for Samsung, LG and Vizio smart TVs, as well as Roku devices. Come June 15th, 2021, you wont be able to access the software on those platforms anymore. Instead, youll need to go through YouTube to watch any content youve bought in the past. Any Google Play credits associated with your account will still be there, allowing you to buy new movies and TV shows. However, your Watchlist wont transfer over, and support for family sharing is more limited.

Google shared the news last month, but it went mostly unnoticed until after websites like Liliputing and 9to5Google published stories on the shutdown earlier today following an email the company sent to users. To be clear, Play Movies and TV itself isnt joining the Google graveyard on June 15th. Google plans to eventually merge the app with its new Google TV software, but that's an ongoing process with the former still available to download on Android and iOS.

From NIH Research Matters

Long-term, or chronic, stress puts people at risk for a variety of health problems. These can include depression and anxiety, as well as problems with digestion and sleep. Chronic stress has also long been linked to hair loss, but the reasons werent well understood.

Hair growth involves three stages. In growth (anagen), strands of hair push through the skin. In degeneration (catagen), hair ceases to grow, and the follicle at the base of the strand shrinks. In rest (telogen), hair falls out and the process can begin again. Hair is among the few tissues that mammals can regenerate throughout their lifetime.

The hair growth cycle is driven by stem cells that reside in the hair follicle. During growth, stem cells divide to become new cells that regenerate hair. In the resting period, the stem cells are inactive. Until now, researchers hadnt determined exactly how chronic stress impaired hair follicle stem cells.

A team led by Dr. Ya-Chieh Hsu of Harvard University studied the underlying mechanisms that link stress and hair loss. The study was supported in part by NIHs National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS). Results appeared in Nature, on March 4, 2021.

The researchers began by testing the role of the adrenal glands, which produce key stress hormonescorticosterone in rodents and cortisol in humans. Removing the adrenal glands from mice led to rapid cycles of hair regrowth. Hair follicle regeneration didnt slow as these mice grew older, like it did in control mice. Rather, hair follicle stem cells continued to enter the growth phase and regenerate hair follicles throughout the animals lifespans. The team was able to restore the normal hair cycle by feeding the mice corticosterone.

Subjecting mice to mild stress over many weeks increased corticosterone levels and reduced hair growth. Hair follicles remained in an extended resting phase. Together, these findings supported the role of corticosterone in inhibiting hair regrowth.

The scientists next examined how corticosterone affects hair follicle stem cells. They found that the stress hormone was not regulating stem cells directly. By deleting the receptor for corticosterone from different cells, they determined that the hormone acts on a cluster of cells underneath the hair follicle called the dermal papilla.

Further studies revealed that corticosterone prevented the dermal papilla from secreting GAS6, a molecule they showed can activate hair follicle stem cells. Delivering GAS6 into the skin restored hair growth in mice fed corticosterone or undergoing chronic stress.

Last year, findings from Hsus team advanced the understanding of how stress causes gray hair. These results reveal a key pathway involved in hair loss from chronic stress. These findings may also lead to further insights into how stress affects tissue regeneration in other parts of the body.

In the future, the Gas6 pathway could be exploited for its potential in activating stem cells to promote hair growth, says first author Dr. Sekyu Choi of Harvard University. However, further study is needed to understand whether the same mechanism is at work in people.

In response to emailed questions, Cellino Biotech CEO and Co-founder Dr. Nabiha Saklayen, talked about the formation of the company and its goal to make stem cell therapies more accessible for patients.

Why did you start this company?

I see a huge need to develop a technology platform to enable the manufacture of cell therapies at scale. We recently closed a $16 million seed financing round led by Khosla Ventures and The Engine at MIT, with participation from Humboldt Fund. Cellino is on a mission to make personalized, autologous cell therapies accessible for patients. Stem cell-derived regenerative medicines are poised to cure some of the most challenging diseases within this decade, including Parkinsons, diabetes, and heart disease. Patient-specific cells provide the safest, most effective cures for these indications. However, current autologous processes are not scalable due to extensive manual handling, high variability, and expensive facility overhead. Cellinos vision is to make personalized regenerative medicines viable at large scale for the first time.

How did you meet your co-founders?

Nabiha Saklayen.

I met my co-founder Marinna Madrid in my Ph.D. research group. We had worked together for many years and had a fantastic working relationship. I then met our third co-founder Matthias Wagner through a friend. Matthias had built and run three optical technology companies in the Boston area and was looking to work with a new team. I was thrilled when we decided to launch the startup together at our second meeting. Matthias built the first Cellino hardware systems in what I like to call Matthias garage. In parallel, I was doing hundreds of expert interviews with biologists in academia and industry, and it started to narrow down our potential applications very quickly. Marinna was doing our first experiments with iPSCs. We iterated rapidly on building new versions of the hardware based on the features that were important to industry experts, such as single-cell precision and automation. Its incredible to witness our swift progress as a team.

What specific need or pain point are you seeking to address in healthcare/life sciences?

In general, autologous therapies are safer for patients because they do not require immunosuppression. The next iteration of cell therapies would use patient-specific stem cells banked ahead of time. Anytime a patient needs new cells, such as blood cells, neurons, or skin cells, we would generate them from a stem cell bank.

Today, patient-specific stem cell generation is a manual and artisanal process. A highly skilled scientist sits at a bench, looks at cells by eye, and removes unwanted cells with a pipette tip. Many upcoming clinical trials are using manual processes to produce stem cells for about ten to twenty patients.

At Cellino, we are converging different disciplines to automate this complex process. We use an AI-based laser system comes to remove any unwanted cells. By making stem cells for every human in an automated, scalable way, we are working towards our mission at Cellino to democratize personalized regenerative medicine.

What does your technology do? How does it work?

Cellinos platform combines label-free imaging and high-speed laser editing with machine learning to automate cell reprogramming, expansion, and differentiation in a closed cassette format, enabling thousands of patient samples to be processed in parallel in a single facility.

In general, autologous, patient-specific stem cell-derived therapies do not require immunosuppression and are safer for patients. Today, patient-specific stem cells are made manually, by hand. To scale the stem cell generation process, Cellino converges different disciplines to automate this complex process. We train machine learning algorithms to characterize cells before our AI-based laser system removes any unwanted cells. By making stem cells for every human in an automated, scalable way, our mission at Cellino is to democratize personalized regenerative medicine. Thats why our vision statement is Every human. Every cell.

Whats your background in healthcare? How did you get to where you are today?

When I arrived at Harvard University for my Ph.D. in physics, I wanted to be closer to real-world applications. Biology is inherently complex and beautiful, and I was interested in developing new physics-based tools to engineer cells with precision. During my Ph.D., I invented new ways to edit cells with laser-based nanomaterials. I collaborated with many brilliant biology groups at Harvard, including the Rossi, Scadden, and Church labs. Working closely with them convinced me that lasers offer a superior solution to editing cells with high precision. That realization compelled me to launch Cellino.

Do you have clinical validation for your product?

Our immediate goal for the next year is to show that our platform can produce personalized, high-quality, R&D-grade stem cells for different patients, which has not been established in an automated manner in the regenerative medicine industry so far. There is significant patient-to-patient variability in manual cell processing, which we eliminate with our platform.

When it comes to Alzheimers versus science, science is on the losing side.

Alzheimers is cruel in the most insidious way. The disorder creeps up in some aging brains, gradually eating away at their ability to think and reason, whittling down their grasp on memories and reality. As the worlds population ages, Alzheimers is rearing its ugly head at a shocking rate. And despite decades of research, we have no treatmentnot to mention a cure.

Too much of a downer? The National Institutes of Health (NIH) agrees. In one of the most ambitious projects in biology, the NIH is corralling Alzheimers and stem cell researchers to come together in the largest genome editing project ever conceived.

The idea is simple: decades of research have found certain genes that seem to increase the chance of Alzheimers and other dementias. The numbers range over hundreds. Figuring out how each connects or influences anotherif at alltakes years of research in individual labs. What if scientists unite, tap into a shared resource, and collectively solve the case of why Alzheimers occurs in the first place?

The initiatives secret weapon is induced pluripotent stem cells, or iPSCs. Similar to most stem cells, they have the ability to transform into anythinga cellular Genie, if you will. iPSCs are reborn from regular adult cells, such as skin cells. When transformed into a brain cell, however, they carry the original genes of their donor, meaning that they harbor the original persons genetic legacyfor example, his or her chance of developing Alzheimers in the first place. What if we introduce Alzheimers-related genes into these reborn stem cells, and watch how they behave?

By studying these iPSCs, we might be able to follow clues that lead to the genetic causes of Alzheimers and other dementiaspaving the road for gene therapies to nip them in the bud.

The iPSC Neurodegenerative Disease Initiative (iNDI) is set to do just that. The project aims to stimulate, accelerate, and support research that will lead to the development of improved treatments and preventions for these diseases, the NIH said. All resulting datasets will be openly shared online, for anyone to mine and interpret.

In plain language? Lets throw all of our new biotech superstarswith CRISPR at the forefrontinto a concerted effort against Alzheimers, to finally gain the upper hand. Its an Avengers, assemble moment towards one of our toughest foesone that seeks to destroy our own minds from within.

Alzheimers disease was first recognized in the early 1900s. Ever since, scientists have strived to find the cause that makes a brain waste away.

The most prominent idea today is the amyloid hypothesis. Imagine a horror movie inside a haunted house with ghosts that gradually intensify in their haunting. Thats the amyloid horrora protein that gradually but silently builds up inside a neuron, the house, eventually stripping it of its normal function and leading to the death of anything inside. Subsequent studies also found other toxic proteins that hang around outside the neuron house that gradually poison the molecular tenants within.

For decades scientists have thought that the best approach to beat these ghosts was an exorcismthat is, to get rid of these toxic proteins. Yet in trial after trial, they failed. The failure rate for Alzheimers treatmentso far, 100 percenthas led some to call treatment efforts a graveyard of dreams.

Its pretty obvious we need new ideas.

A few years ago, two hotshots strolled into town. One is CRISPR, the wunderkind genetic sharpshooter that can snip way, insert, or swap out a gene or two (or more). The other is iPSCs, induced pluripotent stem cells, which are reborn from adult cells through a chemical bath.

The two together can emulate Dementia 2.0 in a dish.

For example, using CRISPR, scientists can easily insert genes related to Alzheimers, or its protection, into an iPSCeither that from a healthy donor, or someone with a high risk of dementia, and observe what happens. A brain cell is like a humming metropolitan area, with proteins and other molecules whizzing around. Adding in a dose of pro-Alzheimers genes, for example, could block up traffic with gunk, leading scientists to figure out how those genes fit into the larger Alzheimers picture. For the movie buffs out there, its like adding into a cell a gene for Godzilla and another for King Kong. You know both could mess things up, but only by watching what happens in a cell can you know for sure.

Individual labs have tried the approach since iPSCs were invented, but theres a problem. Because iPSCs inherit the genetic baseline of a person, it makes it really difficult for scientists in different labs to evaluate whether a gene is causing Alzheimers, or if it was just a fluke because of the donors particular genetic makeup.

The new iNDI plan looks to standardize everything. Using CRISPR, theyll add in more than 100 genes linked to Alzheimers and related dementias into iPSCs from a wide variety of ethnically diverse healthy donors. The result is a huge genome engineering project, leading to an entire library of cloned cells that carry mutations that could lead to Alzheimers.

In other words, rather than studying cells from people with Alzheimers, lets try to give normal, healthy brain cells Alzheimers by injecting them with genes that could contribute to the disorder. If you view genes as software code, then its possible to insert code that potentially drives Alzheimers into those cells through gene editing. Execute the program, and youll be able to observe how the neurons behave.

The project comes in two phases. The first focuses on mass-engineering cells edited with CRISPR. The second is thoroughly analyzing these resulting cells: for example, their genetics, how their genes activate, what sorts of proteins they carry, how those proteins interact, and so on.

By engineering disease-causing mutations in a set of well-characterized, genetically diverse iPSCs, the project is designed to ensure reproducibility of data across laboratories and to explore the effect of natural variation in dementia, said Dr. Bill Skarnes, director of cellular engineering at the Jackson Laboratory, and a leader of the project.

iNDI is the kind of initiative thats only possible with our recent biotech boost. Engineering hundreds of cells related to Alzheimersand to share with scientists globallywas a pipe dream just two decades ago.

To be clear, the project doesnt just generate individual cells. It uses CRISPR to make cell lines, or entire lineages of cells with the Alzheimers gene that can pass on to the next generation. And thats their power: they can be shared with labs around the world, to further hone in on genes that could make the largest impact on the disorder. Phase two of iNDI is even more powerful, in that it digs into the inner workings of these cells to generate a cheat codea sheet of how their genes and proteins behave.

Together, the project does the hard work of building a universe of Alzheimers-related cells, each outfitted with a gene that could make an impact on dementia. These types of integrative analyses are likely to lead to interesting and actionable discoveries that no one approach would be able to learn in isolation, the authors wrote. It provides the best chance at truly understanding Alzheimers and related diseases, and promising treatment possibilities.

A Massive New Gene Editing Project Is Out to Crush Alzheimer's - Singularity Hub

Are you stressed out? Your skin can show it. Studies show that both acute and chronic stress can exert negative effects on overall skin wellness, as well as exacerbate a number of skin conditions, including psoriasis, eczema, acne, and hair loss.

But its not just a one-way street. Research has also shown that skin and hair follicles contain complex mechanisms to produce their own stress-inducing signals, which can travel to the brain and perpetuate the stress response.

You may already have experienced the connection between the brain and skin. Have you ever gotten so nervous that you started to flush or sweat? If so, you experienced an acute, temporary stress response. But science suggests that repeated exposure to psychological or environmental stressors can have lasting effects on your skin that go far beyond flushing and could even negatively affect your overall well-being.

The brain-skin axis is an interconnected, bidirectional pathway that can translate psychological stress from the brain to the skin and vice versa. Stress triggers the hypothalamus-pituitary-adrenal (HPA) axis, a trio of glands that play key roles in the bodys response to stress. This can cause production of local pro-inflammatory factors, such as cortisol and key hormones in the fight-or-flight stress response called catecholamines, which can direct immune cells from the bloodstream into the skin or stimulate pro-inflammatory skin cells. Mast cells are a key type of pro-inflammatory skin cell in the brain-skin axis; they respond to the hormone cortisol through receptor signaling, and directly contribute to a number of skin conditions, including itch.

Because the skin is constantly exposed to the outside world, it is more susceptible to environmental stressors than any other organ, and can produce stress hormones in response to them. For example, the skin produces stress hormones in response to ultraviolet light and temperature, and sends those signals back to the brain. Thus, psychological stressors can contribute to stressed-out skin, and environmental stressors, via the skin, can contribute to psychological stress, perpetuating the stress cycle.

Psychological stress can also disrupt the epidermal barrier the top of layer of the skin that locks in moisture and protects us from harmful microbes and prolong its repair, according to clinical studies in healthy people. An intact epidermal barrier is essential for healthy skin; when disrupted, it can lead to irritated skin, as well as chronic skin conditions including eczema, psoriasis, or wounds. Psychosocial stress has been directly linked to exacerbation of these conditions in small observational studies. Acne flares have also been linked to stress, although the understanding of this relationship is still evolving.

The negative effects of stress have also been demonstrated in hair. One type of diffuse hair loss, known as telogen effluvium, can be triggered by psychosocial stress, which can inhibit the hair growth phase. Stress has also been linked to hair graying in studies of mice. The research showed that artificial stress stimulated the release of norepinephrine (a type of catecholamine), which depleted pigment-producing stem cells within the hair follicle, resulting in graying.

While reducing stress levels should theoretically help to alleviate damaging effects on the skin, theres only limited data regarding the effectiveness of stress-reducing interventions. There is some evidence that meditation may lower overall catecholamine levels in people who do it regularly. Similarly, meditation and relaxation techniques have been shown to help psoriasis. More studies are needed to show the benefit of these techniques in other skin conditions. Healthy lifestyle habits, including a well-balanced diet and exercise, may also help to regulate stress hormones in the body, which should in turn have positive effects for skin and hair.

If you are experiencing a skin condition related to stress, see a dermatologist for your condition, and try some stress-reducing techniques at home.

Leukemia cutis can happen when leukemia cells enter your skin. This rare condition causes patches of discolored skin to appear on the body.

In some cases, the appearance of leukemia cutis lesions on the skin is the first sign of leukemia a cancer of the blood and bone marrow.

Along with standard leukemia therapies, this complication can usually be addressed with topical treatments to help heal the damaged skin. If you have leukemia cutis, your outlook will usually depend on your age and the type of leukemia you have.

Leukemia cutis is an uncommon complication, affecting only about 3 percent of people with leukemia. However, it is often a sign that the cancer is at an advanced stage.

With leukemia, malignant leukocytes (white blood cells) are usually only present in the bloodstream. In the case of leukemia cutis, the leukocytes have entered the skin tissue, causing lesions to appear on the outer layer of your skin. The word cutis refers to the skin, or dermis.

Generally, leukemia cutis results in one or more lesions or patches forming on the outer layer of skin. This condition can mean that the leukemia is more advanced and may have spread to your bone marrow and other organs.

Because there are fewer healthy white cells to combat infections caused by other diseases, rashes and sores may be more common among people with leukemia. Low blood platelets from leukemia can cause damage to blood vessels that appear as red spots or lesions on the skin.

These may include:

However, these skin changes are different than those brought on by leukemia cutis.

While the legs are the most common area for leukemia cutis lesions to appear, they can also form on the arms, face, trunk, and scalp. These skin changes can include:

The lesions usually dont hurt. However, with certain types of leukemia particularly acute myeloid leukemia (AML) the lesions may bleed.

A dermatologist may initially diagnose leukemia cutis based on a physical examination of the skin and a review of your medical history. A skin biopsy is needed to confirm the diagnosis.

Leukemia cutis is a sign of leukemia. It wont develop if the body isnt already dealing with this type of blood cancer.

But leukemia isnt just one disease. There are multiple types of leukemia, each one classified by the kind of cell affected by the disease.

You can also have an acute or a chronic form of leukemia. Acute means it comes on suddenly and usually with more severe symptoms. Chronic leukemia develops more slowly and often with milder symptoms.

The types of leukemia that most commonly trigger leukemia cutis are AML and chronic lymphocytic leukemia (CLL).

Scientists arent sure why cancerous leukocytes migrate to skin tissue in some people with leukemia. It may be that the skin is an optimal environment for healthy leukocytes to transform into cancerous cells.

One possible risk factor that has emerged is an abnormality in chromosome 8, which has been found more often in individuals with leukemia cutis than in those without it.

Treating leukemia cutis usually includes treatment for leukemia as the underlying condition.

The standard leukemia treatment is chemotherapy, but other options may be considered depending on your overall health, your age, and the type of leukemia you have.

Other leukemia treatment options include:

For blood cancers, external beam radiation is a typical form of treatment. With this therapy, a focused beam of radiation is delivered outside the body from various angles. The goal is to injure the DNA in cancer cells to stop them from reproducing.

Immunotherapy, a type of biological therapy, uses the bodys own immune system to fight cancer. It is typically given by an injection that either stimulates immune system cells activity or blocks the signals cancer cells send to suppress the immune response.

Immunotherapy may also be given orally, topically, or intravesically (into the bladder).

Stem cell transplantation is more commonly known as a bone marrow transplant. Bone marrow is where blood stem cells develop. Stem cells can become any type of cell.

Through stem cell transplantation, healthy blood stem cells replace stem cells damaged by the cancer or by chemotherapy or radiation therapy. However, not everyone is a good candidate for this treatment.

Only treating the leukemia cutis lesions will not address the underlying disease of leukemia. That means treatments designed to remove or reduce lesions should be done in combination with systemic treatment for leukemia itself.

Treatments for leukemia cutis symptoms can include:

Again, these treatments will only treat the leukemia cutis lesions, but systemic treatment of the leukemia itself will be needed as well.

The length of time leukemia cutis lesions may last depends on many factors, including how well the leukemia itself is responding to treatment. If the leukemia goes into remission, its unlikely more lesions will appear.

With effective treatment, existing lesions could fade. However, other factors, including your age and overall health, can affect how widespread the lesions are and how long they may last.

There are encouraging trends in the treatment of leukemia, but it remains a challenging disease to treat and live with.

For people with AML who dont have leukemia cutis, research suggests that the survival rate at 2 years is about 30 percent. However, the survival rate drops to 6 percent among people with the skin lesions.

A separate study of 1,683 people with AML found that leukemia cutis was associated with a poor prognosis, and that those with AML and leukemia cutis may benefit from more aggressive treatment.

The outlook for people with CLL is better, with about an 83 percent survival rate at 5 years. The presence of leukemia cutis doesnt seem to change that outlook very much, according to a 2019 study.

Leukemia cutis is a rare complication of leukemia. It happens when malignant leukocytes invade the skin and cause lesions on the skins outer surface.

AML and CLL are more often associated with leukemia cutis than other types of leukemia.

While leukemia cutis usually means the leukemia is in an advanced stage, there are treatments for both the cancer and this uncommon side effect that may help extend life and improve its quality.
