A New Path for Cardiac Stem Cells – hopkinsmedicine.org
By daniellenierenberg
By the time Bill Beatty made it to the Emergency Department in Howard County, he was already several hours into a major heart attack. His physicians performed a series of emergency treatments that included an intra-aortic balloon pump, but the 57-year-old engineers blood pressure remained dangerously low. The cardiologist called for a helicopter to transfer him to Johns Hopkins.
It was fortuitous timing: Beatty was an ideal candidate for a clinical trial and soon received an infusion of stem cells derived from his own heart tissue, making him the second patient in the world to undergo the procedure.
Of all the attempts to harness the promise of stem cell therapy, few have garnered more hope than the bid to repair damaged hearts. Previous trials with other stem cells have shown conflicting results. But this new trial, conducted jointly with cardiologist Eduardo Marbn at Cedars-Sinai Medical Center in Los Angeles, is the first time stem cells come from the patients own heart.
Cardiologist Jeffrey Brinker, M.D., a member of the Hopkins team, thinks the new protocol could be a game-changer. That's based partly on recent animal studies in which scientists at both institutions isolated stem cells from the injured animals hearts and infused them back into the hearts of those same animals. The stem cells formed new heart muscle and blood vessel cells. In fact, says Brinker, the new cells have a pre-determined cardiac fate. Even in the culture dish, he says, theyre a beating mass of cells.
Whats more, according to Gary Gerstenblith, M.D., J.D., the animals in these studies showed a significant decrease in relative infarct size, shrinking by about 25 percent. Based on those and earlier findings, investigators were cleared by the FDA and Hopkins Institutional Review Board to move forward with a human trial.
In Beattys case, Hopkins heart failure chief extracted a small sample of heart tissue and shipped it to Cedars Sinai, where stem cells were isolated, cultured and expanded to large numbers. Hopkins cardiologist Peter Johnston, M.D., says cardiac tissue is robust in its ability to generate stem cells, typically yielding several million transplantable cells within two months.
When ready, the cells were returned to Baltimore and infused back into Beatty through a balloon catheter placed in his damaged artery, ensuring target-specific delivery. Then the watching and waiting began. For the Hopkins team, Beattys infarct size will be tracked by imaging chief Joao Lima, M.D., M.B.A.,and his associates using MRI scans.
Now back home and still struggling with episodes of compromised stamina and shortness of breath, Beatty says his Hopkins cardiologists were fairly cautious in their prognosis, but hell be happy for any improvement.
Nurse coordinator Elayne Breton says Beatty is scheduled for follow-up visits at six months and 12 months, when they hope to find an improvement in his hearts function. But at least one member of the Hopkins team was willing acknowledge a certain optimism. The excitement here, says Brinker, is huge.
The trial is expected to be completed within one to two years.

Fighting cancer with every step to Patagonia – Essex News Daily
By daniellenierenberg
Photo Courtesy of Michael MankowichAbove, Michael Mankowich and his wife, Kathleen, in Patagonia
NUTLEY, NJ When Nutley resident Michael Mankowichs lower back started to bother him, he figured it was a souvenir from his earlier athletic days. Mike, 58, had been a top-notch wrestler at 132 pounds at Long Islands Commack North High School. Hed been an all-American, in fact, as well as a two-time all-Ivy, three-time New York state champ and three-time EIWA tournament placer as a wrestler at Cornell University. An old wrestlers injury was all it was, he figured, a physical reminder of a quick takedown of an opponent 40 years long forgotten.
But the pain did not go away.
Mike began to see a doctor and a chiropractor, and eventually he got an MRI. The news he received at Memorial Sloan Kettering Cancer Center in February 2017 was not good. He was diagnosed with multiple myeloma, a cancer that attacks the blood plasma cells responsible for creating disease-fighting antibodies.
They figured it out quickly at Sloan, he said recently, seated with his wife, Kathleen, in their Rutgers Place home. I kept it from Kathleen.
With this news, he became withdrawn, and his wife realized something was wrong. Mike told her what he had learned, and, as so often happens when a couple puts their heads together, they found some reason for hope: multiple myeloma is a blood disease in the bone marrow and, as such, does not metastasize.
Thats where all the action takes place, in the bone marrow, Mike said. You have to keep your chin up.
For treatment, he became part of a six-month chemotherapy clinical study. Mike was glad to be in the study, because most multiple myeloma patients go on chemotherapy for three months and then undergo a stem-cell transplant. He, however, would not.
A stem-cell transplant blows out the immune system, he said.
Kathleen, an administrative coordinator at Felician University School of Nursing, said her husband, a real estate management employee, did not break stride and never missed the commute to New York City during the clinical study.
A member of Nutley High Schools Class of 1976, Kathleen got on the computer.
When your spouse is diagnosed with an incurable cancer, you do a bit of research, she said.
She discovered the Multiple Myeloma Research Foundation website and learned it was founded 30 years earlier by a woman named Kathy Giusti, who was living with the disease.
That gave me hope, Kathleen said.
She also learned about a collaboration between MMRF and CURE Media Group called Moving Mountains for Multiple Myeloma, or MM4MM.
This collaboration promotes endurance events, undertaken by multiple myeloma patients, to places like Mount Fuji, Mount Kilimanjaro and Iceland. The treks raise money for research, as well as public awareness about the disease. A patient selected to participate in one of these exotic treks had to raise funds, but the trip itself was underwritten by Celgene, a pharmaceutical company headquartered in Summit.
Mike was interested and applied in November 2018 for a spot on a team going to Patagonia. He was interviewed and accepted on condition of raising $10,000 for MMRF research. He suggested that Kathleen accompany him, and they eventually raised $30,000 through social media and by asking friends, family and neighbors.
The online MMRF page devoted to Mikes fundraising shows a photograph of him with his arms around Kathleen and their daughter, Mary, a Class of 2020 NHS student.
In a letter featured on the page, Mike informs the reader that MMRF is one of the worlds leading private funders of myeloma research, with 10 new treatments approved by the Food and Drug Administration.
In August 2019, Mike and Kathleen were flown to Oregon to meet their teammates and to get a taste of what was in store for them in Patagonia. According to the MM4MM website: Each team is carefully selected, representing a microcosm of the myeloma community patients, caregivers, health care professionals and clinical trials managers, as well as representatives from our pharma partners, from CURE Magazine and the MMRF to emphasize the collaboration necessary to drive toward cures.
The foundation sent the group to Mount Hood, Mike said. It was the first time we met. What a great group of people. There were around 15 from all over the country, and there was one other couple, but no one else from New Jersey.
Four other multiple myeloma patients were in the group, he said. he team climbed for nine hours and then headed home.
To prepare for the trip to Patagonia, a region containing part of the Andes mountain range, Mike and Kathleen began a regime of long walks. For instance, theyd walk from Nutley to South Orange and went hiking in New Yorks Harriman State Park.
The MMRF website described the journey as one of arduous adventure: This team will traverse Patagonia crossing over glaciers, through deep valleys, and ascending challenging peaks. This is a powerful and life-changing experience, as the team overcomes challenges, pushes beyond perceived limits and honors loved ones and friends living with multiple myeloma.
For the trek, the team flew to El Calafate, Argentina. As the team embarked on different climbs, documentary filmmakers accompanied them.
The hiking was physically difficult, Mike said. We hiked in rain and incredible winds. In one particular hike, as soon as you felt the winds, you hit the ground. I was surprised nobody got hurt. Some of those slopes were pretty steep. But the scenery was unworldly, and there were condors.
Both Mike and Kathleen agreed that the most memorable sight was La Condorera, which their itinerary described as a nearly vertical massif, offering a home to one of the greatest concentrations of endangered condors in the world. A massif is a group of mountains standing apart from other mountains.
It was a difficult hike, Kathleen said. Youre ready to pass out getting to the top. But its so worth it. The panorama is a view of glaciers and condors. It was spectacular.
Mike and Kathleen returned home on Nov. 16, but there were no goodbyes at the airport. The team had grown so incredibly close that everyone felt they would be seeing each other again, a feeling grounded in the knowledge that multiple myeloma can be challenged and hopefully, one day, defeated.
Our goal in all of this is that you can have multiple myeloma and still do incredible things, Kathleen said.
Its an incentive to other patients to get out there and enjoy their lives, Mike said. And find a cure for multiple myeloma. I have a little bias. I have it.

6 Patients with Rare Blood Disease Doing Well after Gene Therapy Clinical Trial – Lab Manager Magazine
By daniellenierenberg
At left, image shows white blood cells (red) from one of the X-CGD clinical trial participants before gene therapy. At right, after gene therapy, white blood cells from the same patient show the presence of the chemicals (blue) needed to attack and destroy bacteria and fungus.
UCLA Broad Stem Cell Research Center/Nature Medicine
University of California - Los Angeles (UCLA) researchers are part of an international team that reported the use of a stem cell gene therapy to treat nine people with the rare, inherited blood disease known as X-linked chronic granulomatous disease, or X-CGD. Six of those patients are now in remission and have stopped other treatments. Before now, people with X-CGDwhich causes recurrent infections, prolonged hospitalizations for treatment, and a shortened lifespanhad to rely on bone marrow donations for a chance at remission.
"With this gene therapy, you can use a patient's own stem cells instead of donor cells for a transplant," said Dr. Donald Kohn, a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA and a senior author of the new paper, published Jan. 28 in the journal Nature Medicine. "This means the cells are perfectly matched to the patient and it should be a much safer transplant, without the risks of rejection."
People with chronic granulomatous disease, or CGD, have a genetic mutation in one of five genes that help white blood cells attack and destroy bacteria and fungus using a burst of chemicals. Without this defensive chemical burst, patients with the disease are much more susceptible to infections than most people. The infections can be severe to life-threatening, including infections of the skin or bone and abscesses in organs such as lungs, liver or brain. The most common form of CGD is a subtype called X-CGD, which affects only males and is caused by a mutation in a gene found on the X-chromosome.
Other than treating infections as they occur and taking rotating courses of preventive antibiotics, the only treatment option for people with CGD is to receive a bone marrow transplant from a healthy matched donor. Bone marrow contains stem cells called hematopoietic, or blood-forming, stem cells, which produce white blood cells. Bone marrow from a healthy donor can produce functioning white blood cells that effectively ward off infection. But it can be difficult to identify a healthy matched bone marrow donor and the recovery from the transplant can have complications such as graft versus host disease, and risks of infection and transplant rejection.
"Patients can certainly get better with these bone marrow transplants, but it requires finding a matched donor and even with a match, there are risks," Kohn said. Patients must take anti-rejection drugs for six to 12 months so that their bodies don't attack the foreign bone marrow.
In the new approach, Kohn teamed up with collaborators at the United Kingdom's National Health Service, France-based Genethon, the U.S. National Institute of Allergy and Infectious Diseases at the National Institutes of Health, and Boston Children's Hospital. The researchers removed hematopoietic stem cells from X-CGD patients and modified the cells in the laboratory to correct the genetic mutation. Then, the patients' own genetically modified stem cellsnow healthy and able to produce white blood cells that can make the immune-boosting burst of chemicalswere transplanted back into their own bodies. While the approach is new in X-CGD, Kohn previously pioneered a similar stem cell gene therapy to effectively cure a form of severe combined immune deficiency (also known as bubble baby disease) in more than 50 babies.
The viral delivery system for the X-CGD gene therapy was developed and fine-tuned by professor Adrian Thrasher's team at Great Ormond Street Hospital, or GOSH, in London, who collaborated with Kohn. The patients ranged in age from 2 to 27 years old; four were treated at GOSH and five were treated in the US, including one patient at UCLA Health.
Two people in the new study died within three months of receiving the treatment due to severe infections that they had already been battling before gene therapy. The seven surviving patients were followed for 12 to 36 months after receiving the stem cell gene therapy. All remained free of new CGD-related infections, and six of the seven have been able to discontinue their usual preventive antibiotics.
"None of the patients had complications that you might normally see from donor cells and the results were as good as you'd get from a donor transplantor better," Kohn said.
An additional four patients have been treated since the new paper was written; all are currently free of new CGD-related infections and no complications have arisen.
Orchard Therapeutics, a biotechnology company of which Kohn is a scientific co-founder, acquired the rights to the X-CGD investigational gene therapy from Genethon. Orchard will work with regulators in the US and Europe to carry out a larger clinical trial to further study this innovative treatment. The aim is to apply for regulatory approval to make the treatment commercially available, Kohn said.
Kohn and his colleagues plan to develop similar treatments for the other forms of CGDcaused by four other genetic mutations that affect the same immune function as X-CGD.
"Beyond CGD, there are also other diseases caused by proteins missing in white blood cells that could be treated in similar ways," Kohn said.
Early onset Parkinsons might begin in the womb: Prevention a possibility – The New Daily
By daniellenierenberg
An intriguing experiment has led researchers to conclude that people who develop early-onset Parkinsons disease between the age of 21 and 50 may have been born with abnormal brain cells that go undetected for decades.
These disordered cells allow gradual accumulation of the -synuclein protein that forms abnormal deposits in the brain, and dysregulated lysosomal proteins that ordinarily play a role in clearing abnormal proteins from cells.
The researchers from Cedars-Sinai Medical Center say they are investigating an FDA approved skin cancer drug they believe might help correct these abnormalities before they become symptomatic.
In other words, they suggest that early-onset Parkinsons the form of the disease that Michael J. Fox was diagnosed with at the age of 29 may be treatable or even prevented. Its an astonishing claim.
To perform the study, the research team generate pluripotent stem cells master cells that can potentially produce any cell or tissue the body needs to repair itself from blood cells of three patients with young-onset Parkinsons disease.
The patients were aged 30-39 and had no known familial history of the disease and no Parkinsons disease mutations.
When generated in the laboratory, these master cells called induced pluripotent stem cells (iPSCs). In their experiment, the Cedars-Sinai researchers described this process as taking adult blood cells back in time to a primitive embryonic state.
The team used the stem cells to produce dopamine neurons from each patient and then cultured them in a dish and analysed the neurons functions.
In Parkinsons patients, brain neurons that make dopamine a neurotransmitter that works to coordinate muscle movement become impaired or die.
Our technique gave us a window back in time to see how well the dopamine neurons might have functioned from the very start of a patients life, said Dr Clive Svendsen, PhD, director of the Cedars-Sinai Board of Governors Regenerative Medicine Institute, and the studys senior author.
According to a statement from Cedars-Sinai, the researchers detected two key abnormalities in the dopamine neurons in the dish:
Dr Svendsen said the experiment allowed the researchers to see the very first signs of young-onset Parkinsons.
It appears that dopamine neurons in these individuals may continue to mishandle alpha-synuclein over a period of 20 or 30 years, causing Parkinsons symptoms to emerge.
The investigators went further, using their iPSC to test a number of drugs that might reverse the lab-born abnormalities.
They found that that one drug, PEP005 already approved by the Food and Drug Administration for treating pre-cancers of the skin reduced the elevated levels of alpha-synuclein in both the dopamine neurons in the dish and in laboratory mice.
The drug also countered another abnormality they found in the patients dopamine neurons elevated levels of an active version of an enzyme called protein kinase C. However, the role of this enzyme version in Parkinsons is not clear.
The drug PEP005 is only available in gel form and the researchers plans to investigate how it might be delivered to the brain to potentially treat or prevent young-onset Parkinsons.
In Parkinsons disease, the symptoms including slowness of movement, rigid muscles, tremors, loss of balance and impaired mood control get worse over time. In most cases, the exact cause of neuron failure is unclear, and there is no known cure.
Just about every week, a new insight into the disease is published. Last week, The New Daily reported on new research that found living less than 50 metres from a major road or less than 150 metres from a highway has been linked to significantly higher incidence of dementia and Parkinsons disease.
In 2018, we published an exciting Australian study that suggested subject to clinical testing the inflammation of the brain that causes so much of the progressive damage in Parkinsons disease (PD) could be halted by taking a single pill each day.
Both these studies might eventually prove to be correct. But its a long wait for the more than 10 million sufferers worldwide and their families.
This latest study could be a game-changer. But it could just as easily wither on the vine. Still, better to take heart than not.
Most patients are 60 or older when they are diagnosed, about 10 per cent are between 21 and 50 years old. .
Young-onset Parkinsons is especially heartbreaking because it strikes people at the prime of life, said Dr Michele Tagliati, director of the Movement Disorders Program, vice chair and professor in the Department of Neurology at Cedars-Sinai, and co-author of the study.
This exciting new research provides hope that one day we may be able to detect and take early action to prevent this disease in at-risk individuals.

New Bedford firefighter dies of occupational cancer – SouthCoastToday.com
By daniellenierenberg
NEW BEDFORD The New Bedford Fire Department is mourning the death of one of their own.
On Monday morning Russ Horn, who worked for the department for over 30 years, died of occupational cancer, according to the president of New Bedford Firefighters Union, Billy Sylvia.
Sylvia said Horn, who was in his 50s, was forced to retire from the department after being diagnosed with multiple myeloma.
According to a patient blog on the Dana Farber Cancer Institutes website, Horn was diagnosed with cancer of plasma cells in 2014 after a minor slip at work sent him to the emergency room. There they discovered he had two broken ribs and a punctured lung as a result of the cancer already attacking his bones.
After receiving stem cell transplants and participating in clinical trials, Horn retired from the department in 2017.
Firefighters face a 1.53 times greater risk of getting multiple myeloma, according to the Firefighter Cancer Support Network.
Sylvia said he has seen a lot of cancer diagnoses among his colleagues in his 14 years as a firefighter, its adding up really quickly... its more than a handful.
We have active guys dealing with this, we have guys that are contracting it after retirement... studies show how much more susceptible we are, Sylvia said.
Its more than just the smoke theyre breathing thats putting them at risk, according to Sylvia; firefighters also can end up absorbing things through their skin and some of its coming from the gear thats supposed to protect us.
The issue is affecting firefighters across the country, Sylvia said, Were learning more and more, trying to get it under control, but theres still a lot of work that can be done.
Sylvia said Horns family has been proactive about making firefighters aware of their cancer risk and teaching them what to look for and the importance of early cancer screenings.
He was a very strong individual, both mentally and physically, Sylvia said of Horn, Eventually it just took its toll.
In 2019, Horn told Dana-Farber, Id do it all again, referring to his 30 years as a firefighter. This has been really hard, but having the guys behind me 100 percent makes it all a little easier.
Both the New Bedford Fire Department and the union have updated their profile pictures on Facebook to include a black stripe over their logos, honoring Horn.
In a post to the unions Facebook page announcing Horns passing, Sylvia said, Russ was the perfect example of what a firefighter, husband, father, and friend, that anyone could ever be. He was surrounded by his family, friends, brother and sisters firefighters throughout his fight and now beyond.
Sylvia closed the post with, We Love You Russ, Well see you again At the Big One.
On their own Facebook page the New Bedford Fire Department posted, "Our hearts are broken as we learned this morning that our retired brother, FF Russell Horn has lost his brave and courageous battle. We will never forget you and we will keep your family in our thoughts and prayers."
This story will be updated as more information becomes available.

Coronavirus is similar to SARS and causes infection through a heart regulating enzyme: Study – International Business Times, Singapore Edition
By daniellenierenberg
Comparing between SARS, MERS and 2019-nCOv
The Wuhan coronavirus or novel 2019 nCoV, has spread like a wildfire across China and reached the shores of 22 countries as of now. In a bid to stem the spread of the disease, countries have resorted to various preventive and arresting measures. Many laboratories are in the process of formulating a vaccine. However, combating this new pathogen is proving to be a global challenge.
A new study by researchers from the University of Minnesota suggests that understanding the Severe acute respiratory syndrome virus (SARS) or SARS-CoV, which caused global panic in 2002-2003 may help combat the new coronavirus.
After a structural study that lasted for ten years, the researchers have been able to demonstrate the manner of interaction between the SARS-CoV and animals, and human hosts that lead to infection in them. The scientists suggest that the mechanism of infection of the Wuhan coronavirus exhibits similarities to the SARS-CoV, which also is a coronavirus.
Using the data and information acquired from multiple strains of SARS-CoV from diverse hosts from different years, and studying the angiotensin-converting enzyme-2 (ACE2) receptors from various species of host animals, the scientists modelled predictions for the Wuhan coronavirus. Normally, the enzyme is associated with the regulation of cardiac functions. However, both these viruses have been found to gain entry into healthy cells by using ACE2.
"Our structural analyses confidently predict that the Wuhan coronavirus uses ACE2 as its host receptor," the researchers wrote in the study. They state that various other structural details of the new coronavirus are consistent with the ability of the SARS-CoV to recognise the ACE2 receptors to infect the cells, playing a determining role in transmission from hosts to human beings, and human to human.
The researchers also stressed that a single mutation has the ability to increase the potency with which the virus can infect humans. "Alarmingly, our data predict that a single mutation [at a specific spot in the genome] could significantly enhance [the Wuhan coronavirus's] ability to bind with human ACE2," they stated in the study.
It is because of this danger that the evolution of the Wuhan virus among patients must be monitored closely to spot novel mutations in its genomes, the scientists add. This continuous examination may help predict the possibility of an outbreak that could be far more serious than the ones being witnessed the authors stress.
"One of the long -term goals of our previous structural studies on SARS -CoV was to build an atomic -level iterative framework of virus-receptor interactions that facilitate epidemic surveillance, predict species-specific receptor usage and identify potential animal hosts and likely animal models of human diseases," highlighted the authors.
They conclude that this study provides translational and public health research communities with a reiterative framework that may help provide predictive insights enabling the better understanding and counter of the novel 2019 -nCoV.

Team based at Osaka University carries out world’s first transplant of heart cells generated from iPS cells – Medical Herald
By daniellenierenberg
A team based at Osaka University has conducted the first ever transplant of cardiac muscle cells generated from iPS cells, around the globe, in a clinical trial initiated physician.
A professor in the universitys cardiovascular surgery unit, Yoshiki Sawa, together with his colleagues at the university, in a clinical procedure to verify the efficiency and security of the therapy with the help of induced pluripotent stem cells, intend to transplant heart muscle cell sheets over the time of 3 years into 10 individuals undergoing severe heart malfunction a result of ischemic cardiomyopathy.
The team conducted, the present month, an operation on an individual, in an attempt to take a first step into the project. This operation was successful. The individual has now been moved to a general ward.
It is predicted that the cells on the degradable sheets which attach to the hearts surface will grow and eliminate a protein which has the power to regenerate blood vessels and advance cardiac function. Already, the iPS cells have been stored after being taken from the blood cells of healthy donors.
Every sheet that goes on the hearts surface is 4 to 5 centimeters in width, and 0.1 millimeter in thickness.
The team from Osaka University will be observing the patient throughout the year.
At a news conference, Yoshiki Sawa expressed his hopes of the transplant becoming the medical technology that succeeds in saving as many individuals as it can, since he has come across many lives that he was unable to save.
On Monday, the universitys researchers stated how they chose to carry out a clinical trial in a clinical researchs stead so they could gain timely approval from the health ministry for clinical applications.

Cytovia's CAR NK Alliance With NYSCF, UCSF Aims to Overcome Negative Side Effects of CAR T Drugs - Precision Oncology News
Can Parkinsons be prevented as it stealthily develops? – Big Think
By daniellenierenberg
Parkinson's disease comes with slowness, rigidity, tremors, and loss of balance due to an insufficiency of the dopamine that coordinates muscle movement. This disease, of which the rate of diagnosis is rising, occurs when the neurons responsible for producing dopamine malfunction or die. About 500,000 Americans are diagnosed with Parkinson's each year.
Most of the time, Parkinson's disease is a condition of the elderly, diagnosed in people 60 and older. However, about 10% of the time, it's detected in people between 21 and 50. "Young-onset Parkinson's is especially heartbreaking because it strikes people at the prime of life," says Michele Tagliati, an author of a new study from Cedars-Sinai.
The study of brain cells from Parkinson's younger victims has found that the misbehaving neurons are present long before diagnosis typically taking some 20 or 30 years to produce detectable symptoms and may even be present prior to birth. The revelation raises hope for combatting Parkinson's because there's already an approved drug that can mitigate the damage done by the troublemaking neurons before the disease ever appears.
The research is published in the journal Nature Medicine.

The authors' investigation began with an examination of neurons based on cells from young-onset Parkinson's (YOPD) patients who had no known mutations. From the cells, induced pluripotent stem cells (iPSCs) were generated and differentiated into dishes containing cultures of dopamine neurons. Senior study author Clive Svendsen says, "Our technique gave us a window back in time to see how well the dopamine neurons might have functioned from the very start of a patient's life."
The scientists observed lysosomes within the YOPD neurons malfunctioning. Since lysosomes are counted on as "trash cans" for unnecessary or depleted proteins, the castoff chemicals began to pile up. In particular, substantial accumulations of soluble -synuclein, a protein implicated in different types of Parkinson's, were seen.
Says Svendsen, "What we are seeing using this new model are the very first signs of young-onset Parkinson's,"revealing that, "It appears that dopamine neurons in these individuals may continue to mishandle -synuclein over a period of 20 or 30 years, causing Parkinson's symptoms to emerge."
The researchers also saw unexpectedly high levels of the enzyme protein kinase C in its active form, though what that has to do with Parkinson's, if anything, is unknown.

The researchers tested a number of drugs on the cultures to see if any might address the observed accumulations of -synuclein. (They performed parallel tests of laboratory mice.) One drug, PEP005, which is already approved by the FDA for treating skin pre-cancers, did effectively reduce the -synuclein buildup, both in the iPSCs and the mice.
Since PEP005 is currently administered in gel form for treating skin, the researchers are now exploring how the drug might be modified so it can be delivered directly to the brain. The team also plans follow-on research to see if their findings apply equally to forms of Parkinson's beyond YOPD.

Cardio Round-up: Nanoparticles and Stem Cells in the Spotlight – DocWire News
By daniellenierenberg
This weeks Round-up looks to the future, as nanoparticles and stem cell-derived cardiac muscle cells get a closer look. More good news for lovers of yogurt, and a smelly but effective treatment for atherosclerosis as well.
Using stem cells extracted from the patients own blood and skin cells, this Japanese research team completed the first-in-human transplant of cardiac muscle cells derived from pluripotent stem cells. The team achieved this by reprogramming them, reverting them to their embryonic-like pluripotent initial state. I hope that (the transplant) will become a medical technology that will save as many people as possible, as Ive seen many lives that I couldnt save, Yoshiki Sawa, a professor in the Osaka University cardiovascular surgery unit, said in apress report.
Stem Cell-Derived Heart Muscle Transplanted Into Human for First Time: Researchers
Like something from a sci-fi horror novel, this team of researcher examined the role that nanoparticles that eat dead cells and stabilize atherosclerotic plaque may be able to play in the future of atherosclerosis treatment. We found we could stimulate the macrophages to selectively eat dead and dying cells these inflammatory cells are precursor cells toatherosclerosis that are part of the cause of heart attacks, one of the authors said in press release. We could deliver a small molecule inside the macrophages to tell them to begin eating again. The authors noted that after a single-cell RNA sequencing analysis, they observed that the prophagocytic nanotubes decreased inflammatory gene expression linked to cytokine and chemokine pathways in lesional macrophages, thereby treating the cell from the inside out.
Are Nanoparticles Potential Gamechangers for Treating Clogged Arteries?
In this large analysis of more than 120,000 individuals, the authors reported multivariable-adjusted hazard ratios (95% CI for all) for mortality were reduced in regular (more than four servings per week) consumers of yogurt, and there was an inverse relationship between regular consumption and cancer mortality as well as cardiovascular-related mortality in women. In our study, regular yogurt consumption was related to lower mortality risk among women, the authors wrote. Given that no clear doseresponse relation was apparent, this result must be interpreted with caution.
Yogurt Consumption Associated with Reduced Mortality Risk (Plus a Caveat)
This research teamlooked human microphages and compared them to dying cells in a dish. They observed that macrophages reclaim arginine and other amino acids when they eat dead cells, and then use an enzyme to convert arginine to putrescine. The putrescine, in return, activates a protein (Rac1) that causes the macrophage to eat more dead cells, suggesting to the authors that the problem of atherosclerosis may be, in part, a problem of putrescine. The findings, according to the accompanying press release, suggest that the compound could be use to potentially treat conditions with chronic inflammation, such as Alzheimers disease.

Space might be the perfect place to grow human organs – Popular Science
By daniellenierenberg
Three-dimensional printers have now assembled candy, clothing, and even mouse ovaries. But in the next decade, specialized bioprinters could begin to build functioning human organs in space. It turns out, the minimal gravity conditions in space may provide a more ideal environment for building organs than gravity-heavy Earth.
If successful, space-printed organs could help to shorten transplant waitlists and even eliminate organ rejection. Though they still have a long way to go, researchers at the International Space Station (ISS) hope to eventually assemble organs from adult human cells, including stem cells.
The medical field has only recently embraced 3D printing in general, particularly in biomedical fields like regenerative medicine and prosthetics. So far, these printers have produced early versions of blood vessels, bones, and different types of living tissue by churning out repeated layers of bioinka substance comprised of living human cells and other tissue thats meant to mimic the natural environment that surrounds growing organs.
Recently, researchers are finding that Earth might not be the best environment for growing freestanding organs. Because gravity is constantly pushing down on these delicate structures as they grow, researchers must surround the tissues in scaffolding, which can often debilitate the delicate veins and blood vessels and prevent the soon-to-be organs from growing and functioning properly. Within microgravity, however, soft tissues hold their shape naturally, without the need for surrounding supportan observation thats driven researchers to space.
And one manufacturing lab based in Indiana thinks its tech could play a key role in space. The 3D BioFabrication Facility (BFF) is a specialized 3D printer that uses bioink to build layers several times thinner than human hair. It cost about $7 million to build and employs the smallest print tips in existence.
The brainchild of spaceflight equipment developer Techshot and 3D printer manufacturer nScrypt, the BFF headed to the ISS in July 2019 aboard the SpaceX CRS-18.
Currently, the project focuses on building increasingly thick artificial cardiac tissue and delivering it back to Earth. Once the printed cardiac tissue reaches a certain thickness, it gets harder for researchers to ensure that a printed structures layers effectively grow into one another. Ultimately, though, theyd like the organs to arrive here fully formed.
Printed organs would eventually require vasculature and nerve endings to work properly, though that technology doesnt yet exist.
The next stagetesting heart patches under microscopes and within animalscould span over the next four years. As for whole organs, Techshot claims it plans to begin production after 2025. For now, the project is still in its infancy.
If you were to look at what we printed, it looks very modest, says Techshot vice president of corporate advancement Rich Boling. Its just a cuboid-type shape, this rectangular box. Were just trying to get cells to grow one layer into the next.
Cooking organs like pancakes
Compare the manufacturing process to cooking pancakes, Boling says. The space crew first creates a custom bioink pancake mix with the cells sent from Earth, which they load with syringe-like tools into the BFF.
Researchers then insert a cassette into the BFF containing a bioreactora system that mimics the normal bodily functions essential for growing healthy tissue, like providing nutrients and flushing out waste.
Approximately 200 miles below in Greenville, Indiana, Techshot engineers connect with ISS astronauts on a NASA-enabled secure digital pathway. The linkup allows Techshot to remotely command BFF functions like pump pressure, internal temperature, lighting, and print speed.
Next, the actual printing process occurs within the bioreactor and can take anywhere from moments to hours, depending on the shapes complexity. In the final production step, the cell-culturing ADvanced Space Experiment Processor (ADSEP) cooks the theoretical pancake; essentially, the ADSEP toughens up the printed tissue for its journey back to earth. This step could take anywhere from 12 to 45 days for different tissue types. When completed and hardened, the structure heads home.
The researchers have gone through three testing processes so far, each one getting more exact. This March, theyll begin the third round of experiments.
The bioprinter space race
The BFF lab is the sole team developing this specific type of microgravity bioprinter, Boling says. Theyre not the only ones looking to print human organs in space, though.
A Russian project has also entered the bioprinting space race, however their technique highly differs. Unlike the BFFs bioink layering method, Russian biotechnology laboratory 3D Bioprinting Solutions uses magnetic nanoparticles to produce tissue. An electromagnet creates a magnetic field in which levitating tissue forms the desired structuretechnology that appears ripped from the pages of a sci-fi novel.
After their bioprinter fell victim to an October 2018 spacecraft crash, 3D Bioprinting Solutions rebounded; the team now collaborates with US and Israeli researchers at the ISS. Last month, their crew created the first space-bioprinted bone tissue. Similar to the US project, 3D Bioprinting Solutions aims to manufacture functioning human tissues and organs for transplantation and general repair.
Just because we have the technology to do it, should we do it?
If the 3D BioFabrication Facility prospers in printing working human organs, theyd be subject to thorough regulation here on Earth. The US approval process is stringent for any drug, Rich Boling says, posing a challenge for this unprecedented invention. Techshot predicts at least 10 years for space-printed organs to achieve legal approval, though its an inexact estimate.
Along with regulatory acceptance, human tissue printed in microgravity may encounter societal pushback.
Each country maintains varying laws related to medical transplants. Yet as bioengineering advances into the the final frontier, the international scientific research community may need to shape new guidelines for collaboration among the stars.
As the commercialization of low-Earth orbit continues to ramp up in the next few years, it is certainly true that were going to have to take a very close look at the regulations that apply to that, says International Space Station U.S. National Laboratory interim chief scientist Michael Roberts. And some of those regulations are going to stray into questions related to ethics: Just because we have the technology to do it, should we do it?
Niki Vermeulen, a University of Edinburgh science technology and innovation studies lecturer, has researched the social implications of 3D bioprinting experiments. Like any Earth-bound project, she urges scientists not to get peoples hopes up too early in the process; individuals seeking organ transplants could read about the BFF online and think it could soon be ready to meet their needs.
The most important thing now, I think, is expectation management, Vermeulen says. Because its really quite difficult to do this, and of course we really dont know if its going to work. If it did, it would be amazing.
Another main issue is cost. Like other cutting-edge biotechnology innovations, the organs could also pose a major affordability challenge, she says. Techshot claims that a single space-printed organ could actually cost less than one from a human donor, since some people must pay for a lifetime of anti-rejection meds and/or multiple transplants. Theres currently no telling how long the BFF process would actually take, however, compared to the conventional donor route.
Plus, theres potential health risks for recipients: Techshot chief scientist Eugene Boland says cell manipulation always presents a possibility of genetic mutation. Modified stem cells can potentially cause cancer in recipients, for example.
The team is now working to define and minimize any dangers, he says. The BFF experiment adheres to the FDAs specific regulations for human cells, tissues, and cellular and tissue-based products.
Researchers on the ground now hope to perfect human cell manipulation: Over 100 US clinical trials presently test cultured autologous human cells, and several hundred test cultured stem cells with multiple origins.
What comes next
After the next round of printing tests this March, Techshot will share the bioprinter with companies and research institutions looking to print materials like cartilage, bone, and liver tissue. Theyre currently preparing the bioprinter for these additional uses, Boling says, which could advance health care as a whole.
To speed things up for space crews, Techshot is now building a cell factory that produces multiple cell types in orbit. This technology could cut down the number of cell deliveries between Earth and space.
The ISS has taken in plenty of commercial ventures in recent years, Michael Roberts says, and its getting crowded up there. Space-based experiments ramped up between 40 and 50 years ago, though until recently they mostly prioritized satellite communications and remote observation technology. Since then, satellites have shrunk from bus-sized to smaller than a shoebox.
Roberts has witnessed the scientific areas of interest broaden over the past decade to include medicine. Organizations like the National Institutes of Health are now looking to space to improve treatments, and everything from large pharmaceutical companies to small-scale startups want in.
Theyve got something stuck on every surface up there, he says.
As the ISS runs out of space and exterior attachment points, Roberts predicts that commercial ventures will build new facilities built for specific activities like manufacturing and plant growth. He sees it as a good opportunity for further innovation, since the ISS was originally designed for far more general purposes.
Space, as a whole, may start to look quite different from the first exploration age.
Baby boomers may remember glimpsing at a grainy, black-and-white moon landing five decades ago. Within the same lifetime, they could potentially observe the introduction of space-printed organs.

First pain treatment using human stem cells developed – THE WEEK
By daniellenierenberg
Scientists have developed the first treatment for pain using human stem cells, which provides lasting relief in mice in a single treatment, without side effects. If the treatment is successful in humans, it could be a major breakthrough in the development of new non-opioid, and non-addictive pain management, the researchers said.
"Nerve injury can lead to devastating neuropathic pain and for the majority of patients there are no effective therapies," said Greg Neely, an associate professor at the University of Sydney in Australia.
"This breakthrough means for some of these patients, we could make pain-killing transplants from their own cells, and the cells can then reverse the underlying cause of pain," Neely said in a statement.
The study, published in the journal Pain, used human induced pluripotent stem cells (iPSCs) derived from bone marrow to make pain-killing cells in the lab.
The iPSCs are cells which can develop into many different cell types in the body during early life, and growth.
The researchers then put the cells into the spinal cord of mice with serious neuropathic pain, caused by damage or disease affecting the nervous system.
"Remarkably, the stem-cell neurons promoted lasting pain relief without side effects," said study co-author Leslie Caron.
"It means transplant therapy could be an effective and long-lasting treatment for neuropathic pain. It is very exciting," Caron said.
Because the researchers can pick where to put the pain-killing neurons, they can target only the parts of the body that are in pain.
"This means our approach can have fewer side effects," said John Manion, a PhD student and lead author of research paper.
The stem cells used were derived from adult blood samples, the researchers noted.
Their next step will be to perform extensive safety tests in rodents and pigs.
They will then move to human patients suffering chronic pain within the next five years.

Spinal injury researchers find a sweet spot for stem cell injections – New Atlas
By daniellenierenberg
As they do in many areas of medicine, stem cells hold great potential in treating injured spinal cords, but getting them where they need to go is a delicate undertaking. Scientists at the University of California San Diego (UCSD) are now reporting a breakthrough in this area, demonstrating a new injection technique in mice they say can deliver far larger doses of stem cells and avoid some of the dangers of current approaches.
The research focuses on the use of a type of stem cell known as a neural precursor cell, which can differentiate into different types of neural cells and hold great potential in repairing damaged spines. Currently, these are directly injected into the primary cord of nerve fibers called the spinal parenchyma.
As such, there is an inherent risk of (further) spinal tissue injury or intraparechymal bleeding, says Martin Marsala, professor in the Department of Anesthesiology at UCSD School of Medicine.
In experiments on rodents, Marsala and his team have demonstrated a safer and less invasive approach. The scientists instead injected the stem cells in between a protective layer around the spine called the pial membrane and the superficial layers of the spinal cord, a region known as the spinal subpial space.
This injection technique allows the delivery of high cell numbers from a single injection, says Marsala. Cells with proliferative properties, such as glial progenitors, then migrate into the spinal parenchyma and populate over time in multiple spinal segments as well as the brain stem. Injected cells acquire the functional properties consistent with surrounding host cells.
Following these promising early results, the scientists are hopeful that stem cells injected in this way could one day greatly accelerate healing and improve the strength of cell-replacement therapies for several spinal neurodegenerative disorders, including spinal traumatic injury, amyotrophic lateral sclerosis and multiple sclerosis. But first will come experiments on larger animal models closer to the human anatomy in size, which will help them fine tune their technique for the best results.
The goal is to define the optimal cell dosing and timing of cell delivery after spinal injury, which is associated with the best treatment effect, says Marsala.
The research was published in the journal Stem Cells Translational Medicine.

What the Axolotl’s Limb-Regenerating Capabilities Have to Teach Us – Discover Magazine
By daniellenierenberg
As amphibians go, axolotls are pretty cute. These salamanders sport a Mona Lisa half-smile and red, frilly gills that make them look dressed up for a party. You might not want them at your soiree, though: Theyre also cannibals. While rare now in the wild, axolotls used to hatch en masse, and it was a salamander-eat-salamander world. In such a harsh nursery, they evolved or maybe kept the ability to regrow severed limbs.
Their regenerative powers are just incredible, says Joshua Currie, a biologist at the Lunenfeld-Tanenbaum Research Institute in Toronto whos been studying salamander regeneration since 2011. If an axolotl loses a limb, the appendage will grow back, at just the right size and orientation. Within weeks, the seam between old and new disappears completely.
And its not just legs: Axolotls can regenerate ovary and lung tissue, even parts of the brain and spinal cord.
The salamanders exceptional comeback from injury has been known for more than a century, and scientists have unraveled some of its secrets. It seals the amputation site with a special type of skin called wound epithelium, then builds a bit of tissue called the blastema, from which sprouts the new body part. But until recently, the fine details of the cells and molecules needed to create a leg from scratch have remained elusive.
With the recentsequencingandassemblyof the axolotls giant genome, though, and thedevelopment of techniques to modify the creatures genes in the lab,regeneration researchers are now poised to discover those details. In so doing, theyll likely identify salamander tricks that could be useful in human medicine
Already, studies are illuminating the cells involved, and defining the chemical ingredients needed. Perhaps, several decades from now, people, too, might regrow organs or limbs. In the nearer future, the findings suggest possible treatments for ways to promote wound-healing and treat blindness.
The idea of human regeneration has evolved from an if to a when in recent decades, says David Gardiner, a developmental biologist at the University of California, Irvine. Everybody now is assuming that its just a matter of time, he says. But, of course, theres still much to do.
In a working limb, cells and tissues are like the instruments in an orchestra: Each contributes actions, like musical notes, to create a symphony. Amputation results in cacophony, but salamanders can rap the conductors baton and reset the remaining tissue back to order and all the way back to the symphonys first movement, when they first grew a limb in the embryo.
The basic steps are known: When a limb is removed, be it by hungry sibling or curious experimenter, within minutes the axolotls blood will clot. Within hours, skin cells divide and crawl to cover the wound with a wound epidermis.
Next, cells from nearby tissues migrate to the amputation site, forming a blob of living matter. This blob, the blastema, is where all the magic happens, said Jessica Whited, a regenerative biologist at Harvard University, in a presentation in California last year. It forms a structure much like the developing embryos limb bud, from which limbs grow.
This movie shows immune cells, labeled to glow green, moving within a regenerating axolotl fingertip. Scientists know that immune cells such as macrophages are essential for regeneration: When they are removed, the process is blocked.
Finally, cells in the blastema turn into all the tissues needed for the new limb and settle down in the right pattern, forming a tiny but perfect limb. This limb then grows to full size. When all is done, you cant even tell where the amputation occurred in the first place, Whited tellsKnowable Magazine.
Scientists know many of the molecular instruments, and some of the notes, involved in this regeneration symphony. But its taken a great deal of work.
As Currie started as a new postdoc with Elly Tanaka, a developmental biologist at the Research Institute of Molecular Pathology in Vienna, he recalls wondering, Where do the cells for regeneration come from? Consider cartilage. Does it arise from the same cells as it does in the developing embryo, called chondrocytes, that are left over in the limb stump? Or does it come from some other source?
To learn more, Currie figured out a way to watch individual cells under the microscope right as regeneration took place. First, he used a genetic trick to randomly tag the cells he was studying in a salamander with a rainbow of colors. Then, to keep things simple, he sliced off just a fingertip from his subjects. Next, he searched for cells that stuck out say, an orange cell that ended up surrounded by a sea of other cells colored green, yellow and so on. He tracked those standout cells, along with their color-matched descendants, over the weeks of limb regeneration. His observations, reported in the journalDevelopmental Cellin 2016,illuminated several secrets to the regeneration process.

In this image, three days after amputation, the skin (uncolored) has already covered the wound. (Credit: Josh Currie)
For one thing, cell travel is key. Cells are really extricating themselves from where they are and crawling to the amputation plane to form this blastema, Currie says. The distance cells will journey depends on the size of the injury. To make a new fingertip, the salamanders drew on cells within about 0.2 millimeters of the injury. But in other experiments where the salamanders had to replace a wrist and hand, cells came from as far as half a millimeter away.
More strikingly, Currie discovered that contributions to the blastema were not what hed initially expected, and varied from tissue to tissue. There were a lot of surprises, he says.
Chondrocytes, so important for making cartilage in embryos, didnt migrate to the blastema (earlier in 2016, Gardiner and colleaguesreported similar findings). And certain cells entering the blastema pericytes, cells that encircle blood vessels were able to make more of themselves, but nothing else.
The real virtuosos in regeneration were cells in skin called fibroblasts and periskeletal cells, which normally surround bone. They seemed to rewind their development so they could form all kinds of tissues in the new fingertip, morphing into new chondrocytes and other cell types, too.
To Curries surprise, these source cells didnt arrive all at once. Those first on the scene became chondrocytes. Latecomers turned into the soft connective tissues that surround the skeleton.
How do the cells do it? Currie, Tanaka and collaborators looked at connective tissues further, examining the genes turned on and off by individual cells in a regenerating limb. In a 2018Sciencepaper, the team reported thatcells reorganized their gene activation profileto one almost identical, Tanaka says, to those in the limb bud of a developing embryo.
Muscle, meanwhile, has its own variation on the regeneration theme. Mature muscle, in both salamanders and people, contains stem cells called satellite cells. These create new cells as muscles grow or require repair. In a 2017 study inPNAS, Tanaka and colleagues showed (by tracking satellite cells that were made to glow red) that most, if not all, ofmuscle in new limbs comes from satellite cells.
If Currie and Tanaka are investigating the instruments of the regeneration symphony, Catherine McCusker is decoding the melody they play, in the form of chemicals that push the process along. A regenerative biologist at the University of Massachusetts Boston, she recently published arecipe of sorts for creating an axolotl limb from a wound site. By replacing two of three key requirements with a chemical cocktail, McCusker and her colleagues could force salamanders to grow a new arm from a small wound on the side of a limb, giving them an extra arm.
Using what they know about regeneration, researchers at the University of Massachusetts tricked upper-arm tissue into growing an extra arm (green) atop the natural one (red). (Credit: Kaylee Wells/McCusker Lab)
The first requirement for limb regeneration is the presence of a wound, and formation of wound epithelium. But a second, scientists knew, was a nerve that can grow into the injured area. Either the nerve itself, or cells that it talks to, manufacture chemicals needed to make connective tissue become immature again and form a blastema. In their 2019 study inDevelopmental Biology, McCusker and colleagues guided byearlier work by a Japanese team used two growth factors, called BMP and FGF, to fulfill that step in salamanders lacking a nerve in the right place.
The third requirement was for fibroblasts from opposite sides of a wound to find and touch each other. In a hand amputation, for example, cells from the left and right sides of the wrist might meet to correctly pattern and orient the new hand. McCusckers chemical replacement for this requirement was retinoic acid, which the body makes from vitamin A. The chemical plays a role in setting up patterning in embryos and has long been known to pattern tissues during regeneration.
In their experiment, McCuskers team removed a small square of skin from the upper arm of 38 salamanders. Two days later, once the skin had healed over, the researchers made a tiny slit in the skin and slipped in a gelatin bead soaked in FGF and BMP. Thanks to that cocktail, in 25 animals the tissue created a blastema no nerve necessary.
About a week later, the group injected the animals with retinoic acid. In concert with other signals coming from the surrounding tissue, it acted as a pattern generator, and seven of the axolotls sprouted new arms out of the wound site.
The recipe is far from perfected: Some salamanders grew one new arm, some grew two, and some grew three, all out of the same wound spot. McCusker suspects that the gelatin bead got in the way of cells that control the limbs pattern. The key actions produced by the initial injury and wound epithelium also remain mysterious.
Its interesting that you can overcome some of these blocks with relatively few growth factors, comments Randal Voss, a biologist at the University of Kentucky in Lexington. We still dont completely know what happens in the very first moments.
If we did know those early steps, humans might be able to create the regeneration symphony. People already possess many of the cellular instruments, capable of playing the notes. We use essentially the same genes, in different ways, says Ken Poss, a regeneration biologist at the Duke University Medical Center in Durham who describednew advances in regeneration, thanks to genetic tools, in the 2017Annual Review of Genetics.
Regeneration may have been an ability we lost, rather than something salamanders gained. Way back in our evolutionary past, the common ancestors of people and salamanders could have been regenerators, since at least one distant relative of modern-day salamanders could do it. Paleontologists have discovered fossils of300-million-year-old amphibians with limb deformities typically created by imperfect regeneration.Other members of the animal kingdom, such as certain worms, fish and starfish, can also regenerate but its not clear if they use the same symphony score, Whited says.
These fossils suggest that amphibians calledMicromelerpetonwere regenerating limbs 300 million years ago. Thats because the fossils show deformities, such as fused bones, that usually occur when regrowth doesnt work quite right. (Credit: Nadia B Frbisch et al./Proceedings of the Royal Society B, 2014)
Somewhere in their genomes, all animals have the ability, says James Monaghan, a regeneration biologist at Northeastern University in Boston. After all, he points out, all animals grow body parts as embryos. And in fact, people arent entirely inept at regeneration. We can regrow fingertips, muscle, liver tissue and, to a certain extent, skin.
But for larger structures like limbs, our regeneration music falls apart. Human bodies take days to form skin over an injury, and without the crucial wound epithelium, our hopes for regeneration are dashed before it even starts. Instead, we scab and scar.
Its pretty far off in the future that we would be able to grow an entire limb, says McCusker. I hope Im wrong, but thats my feeling.
She thinks that other medical applications could come much sooner, though such as ways to help burn victims. When surgeons perform skin grafts, they frequently transfer the top layers of skin, or use lab-grown skin tissue. But its often an imperfect replacement for what was lost.
Thats because skin varies across the body; just compare the skin on your palm to that on your calf or armpit. The tissues that help skin to match its body position, giving it features like sweat glands and hair as appropriate, lie deeper than many grafts. The replacement skin, then, might not be just like the old skin. But if scientists could create skin with better positional information, they could make the transferred skin a better fit for its new location.
Monaghan, for his part, is thinking about regenerating retinas for people who have macular degeneration or eye trauma. Axolotls can regrow their retinas (though, surprisingly, their ability to regenerate the lens is limited to hatchlings). He is working with Northeastern University chemical engineer Rebecca Carrier, whos been developing materials for use in transplantations. Her collaborators are testing transplants in pigs and people, but find most of the transplanted cells are dying. Perhaps some additional material could create a pro-regeneration environment, and perhaps axolotls could suggest some ingredients.
Carrier and Monaghan experimented with the transplanted pig cells in lab dishes, and found they were more likely to survive and develop into retinal cells if grown together with axolotl retinas. The special ingredientseems to be a distinct set of chemicals that exist on axolotl, but not pig, retinas.Carrier hopes to use this information to create a chemical cocktail to help transplants succeed. Even partially restoring vision would be beneficial, Monaghan notes.
Thanks to genetic sequencing and modern molecular biology, researchers can continue to unlock the many remaining mysteries of regeneration: How does the wound epithelium create a regeneration-promoting environment? What determines which cells migrate into a blastema, and which stay put? How does the salamander manage to grow a new limb of exactly the right size, no larger, no smaller? These secrets and more remain hidden behind that Mona Lisa smile at least for now.

Aprea Therapeutics Receives FDA Breakthrough Therapy Designation for APR-246 in Combination with Azacitidine for the Treatment of Myelodysplastic…
By daniellenierenberg
BOSTON, Jan. 30, 2020 (GLOBE NEWSWIRE) -- Aprea Therapeutics, Inc. (NASDAQ: APRE), a biopharmaceutical company focused on developing and commercializing novel cancer therapeutics that reactivate mutant tumor suppressor protein p53, today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation for APR-246 in combination with azacitidine for the treatment of myelodysplastic syndromes (MDS) with a susceptible TP53 mutation.
MDS represents a spectrum of hematopoietic stem cell malignancies in which bone marrow fails to produce sufficient numbers of healthy blood cells. Approximately 30-40% of MDS patients progress to acute myeloid leukemia (AML) and mutation of the p53 tumor suppressor protein is thought to directly contribute to disease progression and a poor overall prognosis.
Breakthrough Therapy Designation further supports our development program for APR-246 in combination with azacitidine in MDS patients with a TP53 mutation, said Christian S. Schade, Chief Executive Officer of Aprea. Outcomes for MDS patients with a TP53 mutation are poor and there are no current therapeutic options specifically for these patients. We look forward to continued interaction with FDA regarding our ongoing Phase 3 clinical study and our clinical development program to advance APR-246.
The FDAs Breakthrough Therapy Designation is intended to expedite the development and review of a drug candidate that is planned to treat a serious or life-threatening disease or condition when preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapies on one or more clinically significant endpoints.
About p53 and APR-246
The p53 tumor suppressor gene is the most frequently mutated gene in human cancer, occurring in approximately 50% of all human tumors. These mutations are often associated with resistance to anti-cancer drugs and poor overall survival, representing a major unmet medical need in the treatment of cancer.
APR-246 is a small molecule that has demonstrated reactivation of mutant and inactivated p53 protein by restoring wild-type p53 conformation and function and thereby induce programmed cell death in human cancer cells. Pre-clinical anti-tumor activity has been observed with APR-246 in a wide variety of solid and hematological cancers, including MDS, AML, and ovarian cancer, among others. Additionally, strong synergy has been seen with both traditional anti-cancer agents, such as chemotherapy, as well as newer mechanism-based anti-cancer drugs and immuno-oncology checkpoint inhibitors. In addition to pre-clinical testing, a Phase 1/2 clinical program with APR-246 has been completed, demonstrating a favorable safety profile and both biological and confirmed clinical responses in hematological malignancies and solid tumors with mutations in the TP53 gene.
A pivotal Phase 3 clinical trial of APR-246 and azacitidine for frontline treatment of TP53 mutant MDS is ongoing. APR-246 has received Orphan Drug and Fast Track designations from the FDA for MDS, and Orphan Drug designation from the EMA for MDS, AML and ovarian cancer.

Robots don’t have to be so embarrassing – The Outline
By daniellenierenberg
Robots are pathetic. You need only watch a robot soccer fail compilation to see that humans ancient quest to build synthetic replicas of ourselves out of nuts, bolts and wiring has been a bust. Every new, groundbreaking robot inevitably turns out to be an ungodly abomination, either physically inept or utterly incapable of social interaction. Our latest attempt at a full-on humanoid, Sophia, looks like a pre-loved department store mannequin and sounds like a 2007-era chatbot dialed to the VERY DEPRESSED setting. Shed be a walking repudiation of brainless techno-optimism, if she could actually walk.
Even attempts to build simpler, dog-like droids, such as Boston Dynamics Spot, have produced robots barely worthy of the name. They dont look much better than what youd expect from an adult Erector set enthusiasts weekend garage projects. Some people find these things terrifying, but I take my cues from the manufacturers, who seem incredibly proud when one of their creations performs a task as easy as opening a door.
Imitating human intelligence in software has also proven a task more difficult than expected. Despite the well-financed wet dreams of companies like Uber, the automotive industry has begun to quietly admit that truly self-driving cars are going to happen in decades, not just a few years from now. The Blue Brain project, which received a billion euros from the EU in 2013 and promised to simulate a human brain by 2019, did not succeed. Blue Brain seems to have had some success building a 3D atlas of a mouse brain, but the projects supercomputer, which takes up an entire room, is heaving and groaning under the strain of doing the same for a human mind. Valiant efforts to simulate a transparent, one millimetre nematode called C. elegans, ongoing since 2004, have yielded similarly slow progress. C. elegans has 302 neurons. The human brain has 86 billion.
These stuff-ups are endlessly amusing to me. I dont want to mock the engineers who pour thousands of hours into building novelty dogs made of bits of broken toasters, or even the vertiginously arrogant scientists who thought they could simulate the human brain inside a decade. (Inside a decade! I mean, my god!) Well, okay, maybe I do want to mock them. Is it a crime to enjoy watching our cultures systematic over-investment in digital Whiggery get written down in value time and time again?
On the other hand, maybe the people doing this stuff have just figured out that attaching the terms robot or artificial intelligence to whatever youre up to is a great way of attracting investment from rich idiots. Sometimes I feel naive for thinking anyone takes these wild claims seriously, but that is precisely the power of a good ideology. The promises of robotics and AI are so seductive that people suspend their critical faculties. Whether you are a business like Uber striving to eliminate the messy and expensive production input known as human beings, or a normal person desperate for easy transportation or someone to keep your elderly relatives company, the way we talk about robots and AI suggests these smart solutions are just around the corner. Even people with their heads screwed on properly dont seem to understand how credulously the media hypes up their coverage of AI.
What these doomed overreaches represent is a failure to grasp the limits of human knowledge. We dont have a comprehensive idea of how the brain works. There is no solid agreement on what consciousness really is. Is it divine? Is it matter? Can you smoke it? Do these questions even make sense? We dont know the purpose of sleep. We dont know what dreams are for. Sexual dimorphism in the brain remains a mystery. Are you picking up a pattern here? Even the seemingly quotidian mechanical abilities of the human body running, standing, gripping, and so on are not understood with the scientific precision that you might expect. How can you make a convincing replica of something if you dont even know what it is to begin with? We are cosmic toddlers waddling around in daddys shoes, pretending to work at the office by scribbling on the walls in crayon, and then wondering where our paychecks are.
The world is an astonishing place, and the idea that we have in our possession the basic tools needed to understand it is no more credible now than it was in Aristotles day, writes philosopher Thomas Nagel. But accepting this epistemic knuckle sandwich doesnt mean abandoning the pursuit of robotics.
Enter the frogbot, a living machine synthesized by a research team at the Allen Discovery Center at Tufts University in Boston.
Frogbots (called xenobots by their creators, a stupid name I refuse to use), are tiny little artificial animals made out of stem cells from the African clawed frog. They cant do much yet move around on two stumpy legs, carry tiny objects in a pouch but to me, they are stranger and scarier than any robot weve made out of metal and plastic.
A "frogbot" developed by researchers at Tufts University.
There are three basic steps to the frogbot process. First, stem cells that will develop into frog skin and frog heart are grown in a dish. (The proto-heart cells produce rhythmic contractions, which is how the finished frogbots move around.) Second, a computer runs an algorithm that simulates thousands and thousands of different frogbot designs in a virtual environment to see which ones are capable of whatever action you want them to perform. Finally, the designs that are likely to work are physically produced from clusters of stem cells using microsurgery, then let loose in another dish to see what they actually do. So far, they do pretty much whatever we want them to do, within reason.
This is very cool. Even though frogbots are tiny and stupid at the moment, they impress me way more than the conga line of faildroids weve managed to cobble together so far. Of course it makes sense to use materials from existing animals; weve been doing this using selective breeding techniques since the dawn of time. What are pigs or cows or sheep but frogbots built over thousands of years? The key innovation here is modelling selective evolution quickly, instead of standing around like idiots for millenia, waiting for hundreds of generations of dogs to fuck.
It makes perfect sense. Why try to reinvent the wheel when you could simply hijack biological processes that already exist? This is a classically human way of solving a problem, cleverer and yet also lazier than the futile pursuit of purely artificial robotics. A big congratulations to the scientists who figured this out, using only keen wit, a positive attitude, and a gigantic pile of money from the U.S. military research agency.
Yes, naturally this exciting new field of science is being used to develop weapons of war. This, not simply the prospect of new intelligences, is the upsetting thing about groundbreaking developments in robotics and AI. Will frogbots be a military invention that simply slides into everyday life, like the internet, canned food, and microwaves? Or will they be used to administer dangerous MKULTRA hallucinogens to innocent populations America decides are in its way? In a world controlled by a small and powerful elite that can essentially do whatever it wants, were forced to be suspicious of new technologies. Will the frogbot become bigger, smarter, and stronger? Yes, probably. Will it be my comrade? Thats another question entirely.
