New Cardiac Stem Cell Therapy passes Phase I/II Trials – Labiotech.eu (blog)
By JoanneRUSSELL25
TiGenix announces positiveone-year results forits phase I/II trial of donor-derived cardiac stem cell therapy in acute myocardial infarction (AMI).
The Belgian biotech TiGenixis developing allogeneic stem cell therapies. Now the companyhasannouncedthat its cardiac stem cell therapyAlloCSC-01 reached its primary endpoints in aphase I/IItrial.
In 2015, the companyacquired Coretherapixin a292M deal for its allogeneic cardiac stem cell pipeline, which is being developed for the treatment of AMI.The first-in-human trial was designed to test the safety and feasibility of an intracoronary infusion of donor-derivedexpanded cardiac stem cells (AlloCSCs)in patients with AMI and left ventricular dysfunction.
AlloCSC-01consists of adult allogeneic cardiac stem cells isolated from the heartof donors and expanded in vitro. In vivo studies suggest that these cellshave cardio-reparative potential by activating regenerative pathways and promoting the formation of new hearttissue.
Thecurrent phase II study demonstrated thesafety of these allogeneic stem cells. Initial results also revealed a larger reduction of infarct size in a subgroup of patients.
Myocardial infarction caused by blockade of coronary arteries
TiGenix is well known forChondroCellect, which was the first cell therapyto reach the European market for the repair of knee cartilage.After the companyrecently withdrew its market authorization for this product, due to a lack of reimbursement, the biotech is focusing on another stem cell therapy, Cx601, in addition to AlloCSC-01. Under development for Crohns disease, Cx601 is currently awaitingEMA approval and is in phase III trials in the US.
For a late-stage clinical company, TiGenix has a low market cap of191M. Even so, the company seems to be doing well these days with the progress of Cx601 and AlloCSC-01.
If AlloCSC-01 obtains market approval, it could treat the more than 1.9 millionpeople affected by AMI, a major cause of heart failure. So far, most treatments are palliative or restore myocardial function by angioplasty and insertion of a stent to support the vascular lumen.
Stem cell therapy of the heart is definitely not a new topic, but many trials have been conducted using the patients own stem cells derived from the bone marrow. A recent meta-analysisof such trials has suggested that these therapies are safe, but do not enhance cardiac function. TiGenixs approach using allogeneic heart-derived stem cells may offer a new and promisingopportunity in thefield.

Bone marrow recipient encouraging others to "Be the Match" – KXLY Spokane
By JoanneRUSSELL25
SPOKANE, Wash. - A simple cheek swab and a few minutes of your time could save the life of someone in need of a bone marrow transplant.
In 2015, 34-year-old Danielle Vaughan had a stem cell transplant to save her life. For nearly a decade she suffered from mysterious symptoms and illnesses.
"So I had these spin and brain lesions that were very scary," said Danielle Vaughan of Spokane. "I had seizures. I was seeing doctors at Stanford, University of Washington and in Spokane, trying to figure out what was going on."
Eventually, doctors diagnosed Vaughan with Common Variable Immune Deficiency. Her sister, Dina Medin, also had the disorder and underwent a bone marrow transplant a few years ago. The sisters are two of six people in the world with CVID who have had transplants.
"All other treatment options had failed. There was nothing else, that was the only option," said Vaughan.
In September of 2015, Vaughan traveled to Seattle to prepare for the transplant. Vaughan's medical team turned to Be The Match, a national bone marrow donor registry to find her a match. Vaughan said 44 people came back as a perfect match. Her donor was a 27 year old man from the United States. She'd love to meet him one day.
"I would like to say thank you for really giving me a second chance at life. But mostly giving me the opportunity to watch my kids grow," said Vaughan.
Vaughan is now encouraging others to join Be The Match.
"You don't know who you could be helping and you are going to save that person's life," said Vaughan.
The Dairy Queen in Post Falls at 3560 E Seltice Way is hosting a Be The Match donor sign up on Thursday, March 16th from 1:45 p.m.- 4:00 p.m. To register all you need to do is fill out paperwork and swab the inside of your cheek with a special Q-tip.

This Holi, let your skin soak in benefits of Dead Sea Minerals – The Siasat Daily
By JoanneRUSSELL25
New Delhi [India]: Bura na mano holi hai., said Reena and ran away smearing a fistful of artificial colours on her sisters face.
Reena could have never imagined the after-effect this little prank would have on her sisters skin.
The festival of Holi can be a nightmare for people who are allergic to colours. While a couple of measures can be taken beforehand to prevent the skin from any damage, artificial colours can be nasty and can take time to leave your skin.
While a few like to protect themselves from the harsh colours and chemicals, fewer still, pay any heed to the potential skin damage before setting out to have fun.
Most of the inorganic colours have harmful chemicals that can cause allergies, reddening of the skin and burning sensation. Therefore, in order to usher in the festival of colours with pomp and celebration, it is essential to make sure that your skin comes out of the colour explosion perfectly fine.
Instead of scrubbing too much soap or heading to a beauty salon to get rid of the stubborn colours, this Holi, try your hand at Dead Sea Minerals that are high on magnesium, sodium and potassium, says Manisha Chopra, Co-Founder, SeaSoul Cosmeceuticals.
Dead Sea salts can act as an effective exfoliating agent and cleanser. To remove the stubborn colours, try out the dead sea facial mud mask that is loaded with essential ingredients such as Moroccan Argan oil, plant stem cells, noni fruit, goji berries, dead sea minerals, squalane, Aloe Vera, grape seed oil, sodium hyaluronate and Glycerin.
They dramatically help to clear the skin of all impurities and give a transformative effect on the face. Dead Sea Minerals help to get rid of the nasty colours and let you gain back smooth and healthy skin.
The products infused with Dead Sea salts are gentle and safe for all skin types as they are free of parabens and sulphates. Several medical journals have long exalted Dead Sea muds ability to promote radiance as well as its other therapeutic benefits for chronic skin conditions.
A facial polish works amazingly to get rid of the Holi colour as it removes the dead skin which has colours & then polishes the skin & cleanses the skin removing off the Holi colours. After removal of the colour, apply Dead Sea mud mask.
After removing the mask, apply Vitamin C serum to save your skin from after effects of Holi colours.
According to researchers, the Dead Sea water consists of 32% salts with a relatively high concentration of 21 minerals such as magnesium, calcium, bromide and potassium. The calcium present in the Dead Sea salt helps to cleanse pores and soothes and relieves the skin cells.
Magnesium works as an anti-allergic agent and boosts the metabolism of cells. The bromide present in the salt heals and relieves skin disorders and acts as an anti-inflammatory agent.
Sodium Chloride nourishes and hydrates skin cells and removes toxic waste, improving its permeability. Zinc promotes the natural regulation of cell growth and regeneration. It also aids in cell renewal and stimulates collagen and renews skin.
A great antioxidant, this mineral is a free-radical scavenger. It also improves anti-acne properties, anti-inflammatory properties and is a natural UV-rays blocker.
Thus, this Holi, steer clear of any rashes or breakouts on your skin as a result of stubborn colours and opt for miraculous Dead Sea products and play Holi stress-free.
Dead Sea salts can be found in facial care products such as cleansers, toners, moisturizers and masks. Avail the benefits of the wonderful minerals present in the Dead Sea and get ready to celebrate Holi to the fullest. (ANI)

Amid advances in gene therapy, ‘bubble baby’ in SF gains hope – San Francisco Chronicle
By JoanneRUSSELL25
JaCeon Golden has only ever known the inside of hospitals. But the treatment hes receiving may have implications far beyond his as-yet isolated life.
Round-faced and big-eyed, with a perpetual pout that belies his sunny nature, he looks as healthy as any other 5-month-old. But JaCeon was born without a functioning immune system. Even the most banal of infections a cold, a diaper rash could be deadly.
Earlier this year, JaCeon became the first baby at UCSF Benioff Childrens Hospital at Mission Bay to undergo an experimental gene therapy treatment that, doctors hope, will nudge his body to build a new, robust immune system.
From right: Dannie Hawkins checks on her nephew Ja'Ceon Golden, who is being held by patient care assistant Grace Deng at UCSF Benioff Children's Hospital on Wednesday, March 8, 2017, in San Francisco, Calif. Golden, who is five months old, is diagnosed with severe combined immunodeficiency disease (SCID). He is a patient at UCSF, where he stays in a sterile room. The hospital is working on a new gene therapy treatment for SCID. Hawkins brought her nephew Golden from New Mexico for the experimental treatment.
From right: Dannie Hawkins checks on her nephew Ja'Ceon Golden, who...
So far, his results are promising. In a few weeks, JaCeons great aunt, whos also his guardian, hopes to introduce him to the world outside.
Am I going to see him smile when we walk out of here? Dannie Hawkins, 52, said with a glance at the baby, being fed from a bottle by a nurse wearing a gown and gloves. Hows he going to do in the free world?
It will be a while months, probably years before JaCeon is able to fully integrate with that wide world: go to school and birthday parties, ride a public bus, swim in a community pool. But that those activities may be in his future at all is extraordinary.
The treatment given to JaCeon is the result of decades of research into gene therapy that included a string of striking failures that led many doctors to abandon the pursuit altogether.
Gene therapy long had been considered a potential treatment for severe combined immunodeficiency disorder, or SCID, the condition JaCeon was born with, and some other genetic syndromes. The idea is to replace a single gene thats causing trouble.
Even as many doctors gave up on the promise of gene therapy, teams of stubborn scientists kept plugging away. And a few years ago, their experiments started to work, propelled by advances in the understanding of stem cells in this case, a type called hematopoietic stem cells that live in bone marrow and are responsible for generating blood and immune cells and improved methods of delivering genetic repairs.
JaCeon Golden is treated by patient care assistant Grace Deng (center) and pediatric oncology nurse Kat Wienskowski.
JaCeon Golden is treated by patient care assistant Grace Deng...
Now human gene therapy is being tested in trials at UCLA, where a team has treated 20 children with one type of SCID, and at UCSF in collaboration with St. Jude Childrens Research Hospital in Memphis. Both trials are funded by grants from the California Institute for Regenerative Medicine, the states stem cell agency, located in Oakland.
Researchers are studying similar therapies in hopes of curing genetic syndromes like sickle cell disease. And the stem cell agency is funding gene therapy research into potential treatments for HIV, brain cancer and Huntingtons disease, among others.
Gene therapy has been shown to work, the efficacy has been shown. And its safe, said Sohel Talib, a senior science officer at the state stem cell agency. The confidence has come. Now we have to follow it up.
JaCeon was born at a hospital in Las Cruces, N.M., and diagnosed with SCID just after birth as part of a standard newborn screening. He was flown to UCSF, one of a handful of facilities with expertise in SCID, when he was 3 weeks old. His great-aunt joined him about a month later, in November.
The immune disorder is commonly known as bubble baby disease, because until fairly recently kids born with it had to live in isolation, often in plastic bubbles in hospital rooms or their own homes to protect them from infections.
Babies born with SCID have a genetic mutation that leaves their immune system unable to develop disease-fighting cells. Without treatment, most will die within a year. Since the 1970s, some babies with SCID were cured with a bone-marrow transplant. But to be effective, a perfect match was required, almost always from a sibling, and only about a fifth of kids have such a match.
Ja'Ceon Golden is held by patient care assistant Grace Deng, as Deng bottle feeds Golden at UCSF Benioff Children's Hospital on Wednesday, March 8, 2017, in San Francisco, Calif.

The hospital is working on a new gene therapy treatment for SCID. Golden was brought from New Mexico for the experimental treatment.

The rest could undergo a bone marrow transplant from a partial match in JaCeons case, his great-aunt was one but even when that treatment was successful, kids were left with fragile immune systems that required constant maintenance with antibiotics and other boosts.
Gene therapy, though, may prove as effective as a bone marrow transplant from a perfect match.
The procedure starts with doctors harvesting stem cells from a babys own bone marrow, usually taken from the hip. In JaCeons case, his stem cells were sent in January to St. Jude in Memphis, where scientists are perfecting the gene-therapy delivery mechanism.
Sending away JaCeons stem cells was probably the most stressful time of my life, short of my own kids maybe being born, said Dr. Morton Cowan, the lead investigator of the UCSF trial, who has worked in SCID research for more than 30 years.
JaCeons stem cells were flown east over the first big weekend of major storms in California. Flights were being canceled around the clock, and doctors only had a window of about 36 hours to get the fresh cells to the labs in Memphis.
The trip was successful, but not without a hitch. After the cells were engineered and were being sent back to California, the material for a few heart-stopping hours got lost in the mail.
In a couple of months, Cowan said, he hopes to be able to do the gene-therapy delivery at UCSF labs, avoiding the travel headaches.
For now, that still happens at St. Jude. Doctors used a virus in fact, HIV, the virus that causes AIDS to deliver the gene therapy to JaCeons stem cells. The virus is neutered, with all of the disease-causing pieces inside removed.
Whats left is a missile-like shell designed to infiltrate a cell and deliver whatever payload doctors have inserted inside in this case, a healthy gene that will restore the stem cells ability to build normal immune cells.
Back in San Francisco, the cells were infused into JaCeon via a port in his chest. Because theyre his own cells, there was no fear his body would reject them.
He did have to undergo mild chemotherapy to kill off some of his own bone marrow and make room for the re-engineered stem cells to roost, but UCSF has been developing a technique for limiting the dosage of chemotherapy given in gene therapy procedures.
JaCeon suffered no obvious side effects from either the stem cell infusion or the chemotherapy drugs, doctors said.
Hes just thriving. Hes just hes great, Cowan said. He added, We cant open the Champagne just yet, but early tests show the new gene is active, and JaCeon has had an uptick of certain immune cells.
The infusion procedure took just 20 minutes, and JaCeon slept through it, but it felt momentous nonetheless.
It had been difficult to decide to enroll JaCeon in the trial, Hawkins said. Since she was a partial match for a bone marrow transplant, she had the option of giving him the traditional and well-tested therapy.
Shed said to his doctors, So youre telling me hes a guinea pig? They told her, she recalls, If it works, he can open the door for other kids.
That night, as Hawkins slept on the decision, I kept waking up, waking up, all night long, she said. If there was a possibility he could save someone else ... she added, and then broke off in tears.
She spends about six hours with JaCeon every day, beginning each morning with a bath in sterile water, brought by nurses in special tubs. Shes constantly wiping down his toys, clothes, bedding and stuffed animals.
Ive changed a lot of diapers in my time, but this is way more complicated than with other kids, Hawkins said, demonstrating the multistep process she uses to prevent diaper rash.
Im not going to say its been easy, she said. But hes doing fine. I wouldnt have it any other way.

How ‘cannibalism’ by breast cancer cells promotes dormancy: A possible clue into cancer recurrence – Medical Xpress
By JoanneRUSSELL25
March 8, 2017 by Thomas Bartosh, The Conversation Cancer cells, in red, cannibalize a type of stem cell, shown in green. The red cells with small specks of green are breast cancer cells that have eaten the stem cell.
Breast cancer death rates overall have steadily declined since 1989, leading to an increased number of survivors. But while breast cancer survivors are grateful their bodies show no trace of the disease, they still face anxiety. Breast cancer can and does return, sometimes with a vengeance, even after being in remission for several years.
By studying the "cannabilistic" tendency of cancer cells, my research team has made some progress in finding out why.
The chances of recurrence and disease outcome vary with cancer subtype. About one-third of patients diagnosed with triple negative breast cancer, the most aggressive subtype, may experience a recurrence in another part of the body. This is called distant recurrence.
It has been difficult, if not impossible, to predict if and when the same cancer will recur and to stop it. Recurrent disease may arise from just a single cancer cell that survived the initial treatment and became dormant. The dormancy allowed it to hide somewhere in the body, not growing or causing harm for an unpredictable amount of time.
Determining what puts these dormant cells to "sleep" and what provokes them to "wake up" and begin multiplying uncontrollably could lead to important new treatments to prevent a demoralizing secondary cancer diagnosis.
Recently, my research team and I uncovered several clues that might explain what triggers these breast cancer cells to go dormant and then "reawaken." We showed that cell cannibalism is linked to dormancy.
How do bone stem cells affect breast cancer?
Breast cancer can recur in the breast or in other organs, such as the lungs and bone. Where breast cancer decides to grow depends largely on the microenvironment. This refers to the cells that surround it, including immune cells, cells comprising blood vessels, fibroblasts and the select proteins they produce, among other factors.
Over a century ago, a surgeon named Stephen Paget famously compared the organ-specific prevalence of cancer metastasis to seeds and soil. Because breast cancer often relapses in bones, in this metaphor, which still holds forth today, the bone marrow provides a favorable microenvironment (the "soil") for dormant breast cancer cells (the "seeds") to thrive.
Thus, a substantial amount of recent work has involved trying to determine the role in cancer dormancy of a special type of cell, called mesenchymal stem cells (MSCs). These are found in bone marrow.
MSCs in bone marrow are highly versatile. They are able to form bone, cartilage and fibrous tissue, as well as cells that support the immune system and formation of blood. They are also known to travel to sites of tissue injury and inflammation, where they aid in healing.
Breast cancer cells readily interact with MSCs if they meet in the bone marrow. They also readily interact if the breast cancer cells recruit them to the site of the primary tumor.
My research team and I recently focused on potential outcomes of these cellular interactions. We found an odd thing happens, which may provide insight into how these breast cancer cells hide for a long time.
In the laboratory setting, we produced breast tumor models containing MSCs. We also re-created the hostile conditions that naturally challenge developing tumors in patients, such as localized nutrient deficits caused by rapid growth of cancer cells and overcrowding.
We discovered that cancer cells under this duress become dormant after eating, or "cannibalizing," the stem cells.
Our analysis provided compelling data demonstrating that the cannibalistic breast cancer cells did not form tumors as rapidly as other cancer cells, and sometimes not at all. At the same time, they became highly resistant to chemotherapy and stresses imposed by nutrient deprivation.
Dormant cells are widely linked to recurrence. We hypothesize that cannibalism thus is linked to recurrence.
What is cellular cannibalism, and why is it important in cancer?
Cellular cannibalism, in general, describes a distinct phenomenon in which one cell engulfs and eliminates neighboring, intact cells.
The percentage of cancer cells that show cannibalistic activity is relatively low, but it does appear to increase in more aggressive tumors.
There are several reasons breast cancer cells would want to eat other cells, including other cancer cells. It provides them with a way to feed when nutrients are in short supply. It also provides them a way to eliminate the very immune cells that naturally stop cancer growth. Cell cannibalism might also allow cancer cells to inherit new genetic information and, therefore, new and advantageous traits.
Notably, in our study, cannibalistic breast cancer cells that ate the stem cells and entered dormancy began to produce an array of specific proteins. Many of these proteins are also secreted by normal cells that have permanently stopped dividing, or senescent cells, and have been collectively termed the senescence-associated secretory phenotype (or SASP). Although cellular senescence is a part of aging, we are now realizing that it is also important for a variety of normal bodily processes, development of embryos and injury repair in adults.
This suggests that although dormant cancer cells do not multiply rapidly or form detectable tumors, they are not necessarily sleeping. Instead, at times they might be actively communicating with each other and their microenvironment through the numerous proteins they manufacture.
Overall, this might be a clever way for dormant cancer cells to "fly under the radar" and, at the same time, modify their microenvironment, making it more suitable for them to grow in the future.
Can cell cannibalism be exploited for diagnosis and treatment?
Although our results are promising, it's important to be cautious. While there appears to be a strong correlation between cell cannibalism and dormancy, for now we do not know if it is directly linked to cancer recurrence in patients. Studies are underway, however, to corroborate our findings.
Still, the fact that breast cancer cells cannibalize MSCs is intriguing. It provides an important foundation for developing new diagnostic tools and therapies. Indeed, we currently have several ways of applying our recent discoveries.
One exciting idea is to exploit the cannibalistic activity of cancer cells to feed them suicide genes or other toxic agents, using MSCs as a delivery vehicle, like a tumor-seeking missile.
Importantly, MSCs can be easily obtained from the body, expanded to large numbers in the laboratory, and put back into the patient. Indeed, they have already been used safely in clinical trials to treat a variety of diseases due to their ability to aid in tissue repair and regeneration.
A different avenue for drug development would involve keeping dormant cells in a harmless and nondividing state forever. It might also be possible to prevent cancer cells from eating the stem cells in the first place.
In our study, we were able to block cell cannibalism using a drug that targets a specific protein inside cancer cells. With this treatment approach, the cancer might essentially starve to death or be more easily killed by conventional therapies.

Opinion/Commentary: Global stem cell therapy market to showcase growth – The Daily Progress
By JoanneRUSSELL25
LONDON Technavio analysts forecast the global stem cell therapy market to grow at a compound annual growth rate of close to 37 percent during the forecast period, according to their latest report.
The research study covers the present scenario and growth prospects of the global stem cell therapy market for 2017-2021. To determine the market size, the study considers revenue generated from allogenic and autogenic stem cell therapies.
The Americas are the largest regional segment of the global stem cell therapy market, responsible for generating over 56 percent of the total revenue (2016 figures). The region is expected to continue market dominance through the forecast period, driven by increasing demand for stem cell therapy products and investments into R&D.
Technavio analysts highlight the following factors as contributing to the growth of the global stem cell therapy market:
Increase in federal funding in stem cell therapy.
Sapna Jha, one of the lead research analysts at Technavio for medical imaging research, says, Many stem cell research institutes and small companies are involved in cutting-edge R&D and are yielding encouraging results. These institutions are witnessing an increased flow of investments from federal organizations, due to the realization of the importance of regenerative medicine.
The U.S. National Institutes of Health, a major funding government organization invested approximately USD 1.5 billion in stem cell research projects in 2016. Similarly, several state-level organizations such as California Institute for Regenerative Medicine has contributed USD 3 billion to stem cell research in 2014. Such funding will help various research institutes to discover and develop regenerative medicines, which will boost the global regenerative medicine market enormously.
Growing demand for personalized medicine.
The health care sector is creating a high demand for personalized medicine, which could offer game-changing opportunities for the vendors. These medicines offer treatments based on the individual characteristics, needs, and preferences, which will vastly improve the quality of health care. Individuals are increasingly banking their stem cells for future treatments. Research organizations are also extensively exploring ways to develop personalized treatments with stem cells, which could eventually erase the conventional medicine system and help in the effective treatment of various diseases such as diabetes and cancer.
Demand for development of effective drugs for cardiology and degenerative disorders.
There has been an increased demand to develop effective drugs for cardiology and degenerative disorders, for which there were no effective treatment plans before the advent of stem therapies. The discovery of possible cardiac stem cells uncovered new arenas to repair hearts injured due to acute myocardial infarction or coronary artery disease, says Sapna.
Researchers are studying and developing approximately 19 product candidates for the treatment of cardiac disorders, with eight of them in Phase III, and six in Phase II.
Technavio is a global technology research and advisory company. This report was made available through The Associated Press.

Heart Disease | Harvard Stem Cell Institute (HSCI)
By JoanneRUSSELL25
The Harvard Stem Cell Institute is developing new techniques to grow and transplant heart cells, replacing those lost to cardiovascular disease.
The greatest threat to the long-term health and well-being of people living with diabetes is cardiovascular disease. The diabetic population as a whole is two to four times more likely than non-diabetics to develop heart disease or suffer a stroke. Type 1 diabetes, which is most often diagnosed in childhood and adolescence, is particularly devastating, as one New England Journal of Medicine study associated it with a ten-fold increase in cardiovascular disease.
The human adult heart has about five billion heart cells, all pulsing as a coordinated orchestra with every heartbeat. These cells can be killed by high blood pressure, blood clots, heart attacks, and other byproducts of cardiovascular disease. The heart has an age-related block in its ability to make new heart cells, so that damaged cells are not replaced in the latter half of life, precisely when we need them the most. A typical patient with heart failure has lost over a billion heart cells.
Harvard Stem Cell Institute (HSCI) investigators are developing ways to make replacement heart cells and provide them with the right cues so that the new cells play as needed in the orchestra.
Both embryonic stem cells and induced pluripotent stem cells mature cells that are manipulated back to a stem cell state can be harnessed to create new heart cells. The difficulty is that the heart cells made with stem cells resemble the heart cells of an infant, rather than adult heart cells. To function in adult hearts, the new heart cells must mature and then be able to survive within the constantly beating environment of the heart.
The scientific community has generated the technology to make heart cells that are immature, but very few heart cells derived from stem cells integrate into the normal heart tissue as mature heart cells. At the HSCI, our researchers are focused on understanding how to take these new heart cells all the way to maturity and stability, so they can be used as an effective therapy.
HSCI scientists are also developing ways of using the bodys heart matrix the rich, intricate scaffold of the heart that serves as the permanent home for our heart cells to guide maturation and prolong the survival of heart cells derived from stem cells after implantation.
The heart matrix is like the sheet music for the heart orchestra. It tells the heart cells where to sit and how to function with their neighbors so that a heartbeat is in sync. The problem of redrawing these matrix-directed instructions from scratch once seemed too daunting to tackle.
By breaking down the hearts scaffold material into thousands of individual chemicals, HSCI researchers hope to rebuild the environments that allow immature heart cells to mature. Armed with this knowledge, it will be possible to construct real adult heart tissue in the laboratory, as well as realistic approaches to transplanting patient-specific heart cells into their damaged organs.
In addition to these ambitious projects, HSCI is pursuing interim objectives before reaching the ultimate goal of reconstructing the heart. For example, a recent study led to the identification of a blood circulating factor that declines with age but, when injected, can reverse age-related heart enlargement and accompanying heart failure. If this is successful in human studies, we will have identified a new therapeutic approach for the aging heart.

Family appeals for bone marrow donor to save father – Easterneye (press release) (subscription)
By JoanneRUSSELL25
THE family of a man urgently in need of a bonemarrow transplant has appealed to the Asian community to donate their stem cells in the hope of finding a suitable match to save his life.
Father of two, Yevi Ilangakoon, was diagnosed with myelofibrosis in 2009. It is a rare condition where scar tissue builds up inside the bone marrow, affecting its ability to create healthy blood cells, which affects one person in every 100,000.
The 63-year-old, who is originally from Sri Lanka and now lives in Whitstable, has seen his health deteriorate rapidly and his illness could now progress into leukemia if he is not treated.
His only option is to have a bone-marrow transplant using stem cells. However, specialists have been unable to find a 100 per cent match despite searching worldwide registers.
From the entire register, only four per cent are from a south Asian background.
Yevis son Yovaan told Eastern Eye: Its a lifethreatening disease and has been managed with medication for the past eight years, but the condition has got more and more aggressive, especially over the last few months. If he doesnt have a stem-cell transplant, it will be a few months to a year that he will have to live.
So it is quite crucial that we get as close to 100 per cent match as we can. He gets very, very tired because his hemoglobin levels are low. If he has an injury, it takes ages to heal. We are praying and being positive and trying to raise awareness.
Yovaan highlighted the issue on social media, which attracted the attention of Sri Lankan cricketer Mahela Jayawardena, but the family are still urging members of the public to get on the bone marrow register to find a match for Yevi.
The 29-year-old added: It could be your family member your mum or your dad, you dont know what position you are going to be in in a few years time.
If you are on the register, you have the chance of saving someones life. Its a really easy process.
Signing up online takes two minutes and participants simply need to swab the inside of their cheek with a cotton bud they are sent, and send it back in a pre-paid envelope.
Sarah Rogers of the Anthony Nolan charity said: We urgently need more people from Indian and South Asian backgrounds to register as stem cell donors to make sure that everyone, regardless of background, can receive a second chance at life.
At the moment we find a perfect match for about 60 per cent of northern European patients who need a transplant, but that drops to around 20 per cent for any patient of ethnic minority.
If you are above 30, go to: http://www.dkms.org.uk/en/ register-now. Under 30, register at http://www.anthonynolan.org/apply-join-bone-marrow-register.

Gene Therapy: A Breakthrough for Sickle Cell Anemia? – Auburn Citizen
By JoanneRUSSELL25
WEDNESDAY, March 1, 2017 (HealthDay News) -- Researchers are reporting early success using gene therapy to treat, or even potentially cure, sickle cell anemia.
The findings come from just one patient, a teenage boy in France. But more than 15 months after receiving the treatment, he remained free of symptoms and his usual medications.
That's a big change from his situation before the gene therapy, according to his doctors at Necker Children's Hospital in Paris.
For years, the boy had been suffering bouts of severe pain, as well as other sickle cell complications that affected his lungs, bones and spleen.
Medical experts stressed, however, that much more research lies ahead before gene therapy can become an option for sickle cell anemia.
It's not clear how long the benefits will last, they said. And the approach obviously has to be tested in more patients.
"This is not right around the corner," said Dr. George Buchanan, a professor emeritus of pediatrics at the University of Texas Southwestern Medical Center in Dallas.
That said, Buchanan called the results a "breakthrough" against a disease that can be debilitating and difficult to treat.
Buchanan, who wasn't involved in the research, helped craft the current treatment guidelines for sickle cell.
"This is what people have been wanting and waiting for," he said. "So it's exciting."
Sickle cell anemia is an inherited disease that mainly affects people of African, South American or Mediterranean descent. In the United States, about 1 in 365 black children is born with the condition, according to the U.S. National Heart, Lung, and Blood Institute.
It arises when a person inherits two copies of an abnormal hemoglobin gene -- one from each parent. Hemoglobin is an oxygen-carrying protein in the body's red blood cells.
When red blood cells contain "sickle" hemoglobin, they become crescent-shaped, rather than disc-shaped. Those abnormal cells tend to be sticky and can block blood flow -- causing symptoms such pain, fatigue and shortness of breath. Over time, the disease can damage organs throughout the body.
There are treatments for sickle cell, such as some cancer drugs, Buchanan pointed out, but they can be difficult to manage and have side effects.
There is one potential cure for sickle cell, Buchanan said: a bone marrow transplant.
In that procedure, doctors use chemotherapy drugs to wipe out the patient's existing bone marrow stem cells -- which are producing the faulty red blood cells. They are then replaced with bone marrow cells from a healthy donor.
A major problem, Buchanan said, is that the donor typically has to be a sibling who is genetically compatible -- and free of sickle cell disease.
"We've known for a long time that bone marrow transplants can work," Buchanan said. "But most patients don't have a donor."
That's where gene therapy could fit in. Essentially, the aim is to genetically alter patients' own blood stem cells so they don't produce abnormal hemoglobin.
In this case, the French team, led by Dr. Marina Cavazzana, of Necker Children's Hospital's biotherapy department, focused on a gene called beta globin. In sickle cell anemia, beta globin is mutated.
First, the researchers extracted a stem cell supply from their teen patient's bone marrow, before using chemotherapy to wipe out the remaining stem cells.
Then they used a modified virus to deliver an "anti-sickling" version of the beta globin gene into the stem cells they'd removed pre-chemo. The modified stem cells were infused back into the patient.
Over the next few months, the boy showed a growing number of new blood cells bearing the mark of the anti-sickling gene. The result was that roughly half of his hemoglobin was no longer abnormal.
In essence, Buchanan explained, the therapy "converted" the patient to sickle-cell trait -- that is, a person who carries only one copy of the abnormal hemoglobin gene. Those individuals don't develop sickle cell disease.
"This is encouraging," said Dr. David Williams, president of the Dana-Farber/Boston Children's Cancer and Blood Disorders Center.
But, he cautioned, "the caveat is, this is one patient, and 15 months is a short follow-up."
Williams and his colleagues are studying a different approach to sickle cell gene therapy. It aims to restart the body's production of healthy fetal hemoglobin -- to replace the abnormal "adult" hemoglobin seen in sickle cell.
The hope, Williams said, is that gene therapy will ultimately offer a one-time treatment that cures sickle cell. But no one knows yet whether that will happen.
According to Williams, two key questions are: What's the long-term safety? And will the altered stem cells last for a patient's lifetime?
If gene therapy is proven to work, there will no doubt be practical obstacles to its widespread use, according to Buchanan. It's a high-tech treatment, and many sickle cell patients are low-income and far from a major medical center, he said.
But, Buchanan said, the new findings have now "opened a door."
The study was partly funded by Bluebird Bio, the company developing the therapy.
The results were published March 1 in the New England Journal of Medicine.

Will Sickle Cell Be the Next Disease Genetic Engineering Cures? – Gizmodo

Sickle cell disease is a slow, vicious killer. Most people diagnosed with the red blood cell disorder in the US live to be between 40 and 60. But those years are a lifetime of pain, as abnormal, crescent-shaped hemoglobin stops up blood flow and deprives tissues of oxygen, causing frequent bouts of agony, along with more severe consequences like organ damage. Now, after decades of searching for a cure, researchers are announcing that, in at least one patient, they seem to have found a very promising treatment.
Two years ago, a French teen with sickle cell disease underwent a gene therapy treatment intended to help his red blood cells from sickling. In a paper published Thursday in the New England Journal of Medicine, the researchers revealed that today, half of his red blood cells have normal-shaped hemoglobin. He has not needed a blood transfusion, which many sickle cell patients receive to reduce complications from the disease, since three months after his treatment. He is also off all medicines.
To reiterate, the paper is a case study of just one patient. Bluebird Bio, the Massachusetts biotech company that sponsored the clinical trial, has treated at least six other trials underway in the US and France, but those results have not yet been fully reported. The gene therapy has not worked quite as well in some of those other patients; researchers say they are adjusting the therapy accordingly. It is also possible that the boy may eventually experience some blood flow blockages again in the future.
The results, though early, are encouraging. They represent the promise of new genetics technologies to address a disease that has long been neglected and tinged with racism. Sickle cell disease affects about 100,000 people in the US, most of whom are black. It is an inherited genetic disease caused by a mutation of a single letter in a persons genetic code.
This single-letter mutation makes it a promising candidate for cutting edge technologies, like the gene-editing technique CRISPR-Cas9, and other gene therapies. Recently, a rush of new research has sought to address it. Two other gene therapy studies for sickle cell are underway in the US one at UCLA and another at Cincinnati Childrens Hospital. Yet another is about to start in a collaboration between Harvard and Boston Childrens Hospital. Last fall, researchers all demonstrated the ability to correct the mutation in human cells using CRISPR, though that strategy will yet have to surpass significant scientific and political hurdles before reaching clinical trials.
In the new study, researchers took bone marrow stem cells from the boy and fed them corrected versions of a gene that codes for beta-globin, a protein that helps produce normal hemoglobin. The hope was that those altered stem cells would interfere with the boys faulty proteins and allow his red blood cells to function normally. They continued the transfusions until the transplanted cells began to produce normal-shaped hemoglobin. In the following months, the numbers of those cells continued to increase until in December 2016, they accounted for more than half the red blood cells in his body. In other words, so far so good.
Currently, the only long-term treatment for sickle cell disease is a bone marrow transplant, a high-risk, difficult procedure which many patients are not even eligible for. Pain and other side-effects are treated with blood transfusions for temporary relief. New technologies offer the hope of a solution that could provide long-term relief and allow patients to live some semblance of a normal life.
For decades, gene therapies have been touted as a cure for everything. But so far, successes have been infrequent, and often for very rare diseases. But early success in treating sickle cell disease means that soon, if were lucky, the benefits of this technology may reach hundreds of thousands of people.

Schizophrenia May Begin In The Womb, Skin Cells Suggest – ReliaWire
By JoanneRUSSELL25
The skin cells of four adults with schizophrenia provide a unique insight into how the disease began before they were born.
Scientists call the findings the first proof of concept for the hypothesis that a common genomic pathway lies at the root of schizophrenia. They add the work is a step toward the design of treatments that could be administered to pregnant mothers at high risk for bearing a child with schizophrenia, potentially preventing the disease before it begins.
Michal K. Stachowiak, professor of pathology and anatomical sciences at the University at Buffalo, says:
In the last 10 years, genetic investigations into schizophrenia have been plagued by an ever-increasing number of mutations found in patients with the disease. We show for the first time that there is, indeed, a common, dysregulated gene pathway at work here.
The authors used skin cells from four adults with schizophrenia and four adults without the disease. The cells were reprogrammed back into induced pluripotent stem cells and then into neuronal progenitor cells.
By studying induced pluripotent stem cells developed from different patients, we recreated the process that takes place during early brain development in utero, thus obtaining an unprecedented view of how this disease develops, said Stachowiak. This work gives us an unprecedented insight into those processes.
Stachowiak says the research is a proof of concept for a hypothesis he and colleagues published in 2013 that proposed that a single genomic pathway, called the Integrative Nuclear FGFR 1 Signaling (INFS), is a central intersection point for multiple pathways involving more than 100 genes believed to be involved in schizophrenia.
This research shows that there is a common dysregulated gene program that may be impacting more than 1,000 genes and that the great majority of those genes are targeted by the dysregulated nuclear FGFR1, Stachowiak says.
When even one of the many schizophrenia-linked genes undergoes mutation, by affecting the INFS it throws off the development of the brain as a whole, similar to the way that an entire orchestra can be affected by a musician playing just one wrong note, he says.
The next step in the research is to use these induced pluripotent stem cells to further study how the genome becomes dysregulated, allowing the disease to develop.
We will utilize this strategy to grow cerebral organoidsmini-brains in a senseto determine how this genomic dysregulation affects early brain development and to test potential preventive or corrective treatments.
The work was funded by NYSTEM, the Patrick P. Lee Foundation, the National Science Foundation, and the National Institutes of Health.

Stem Cells Saved His Life. Two Years Later, He Met The Donor – NDTV
By JoanneRUSSELL25
Kolkata: Joy knew no bounds for 42-year-old Nilesh Sinha, when he hugged his saviour, 27-year-old Sajat Jain. Mr Sinhacalls it the warmest and most meaningful hug of his life.
Two years ago, Mr Sinha was suffering fromAplastic Anemia, a rare disease in which the bone marrow and the hematopoietic stem cells that reside there are damaged. Only a stem cell transplant could have saved himfrom his deteriorating condition and Mr Jains were a perfect match.
The peripheral blood stem cell or PBSC transplant took place at Kolkatas Tata Memorial Centre in 2015. Last week, the two came face-to-face for the first time at an event organised by Datri, Indias largestadult unrelated blood stem cell donors registry, which aided the transplant between the two.
Mr Sinha said he was ecstatic to find the opportunity to say thanks to the man he owes his life to. Sajat is my childrens new superhero, he said.Mr Jain toocould not believe that his simple act saved someones life.
Mr Sinha told NDTV that he is sure that once people get to know about Mr Jain, they will also come forward to register themselves as stem cell donors and after them, the next generation will also get motivated.
Mr Jain, who runs a healthcare start-up, said that he became a donor while researching for his company and could save Mr Sinhas life just in time, after a donor backed out. He wants more young people to register so that someone in need can be benefited.
I was actually pretty excited. I know I was able to save someones life and not too many people can say that in their lifetime. When I actually saw his face, I remembered his previous condition and was delighted to see how fit he had become, Mr Jain told NDTV.
Kolkata has seen 300 successful stem cell transplants so far. Director of Tata Memorial Centre, Kolkata, Dr Mammen Chandy told NDTV that there is a need for more donors in India. When a donor asks me what is the risk of a donation, I would say, what is the risk of crossing the street outside my hospital and not being hit by a bus? he said.
In 2009, Datri came to the aid of people suffering from life threatening blood disorders like leukaemia, lymphoma, severe aplastic anemia, sickle cell disease, thalassemia among others. It started with 3,000 people pledging to donate stem cells and today there are 93,000 registered donors with them. With this small number of registered donors, however, the possibility of finding a match for an Indian anywhere in the world is very bleak.
Blood stem cells from a donor can give someone a second chance at life and a patient has 25 per cent chance of finding a match within the family. There are three sources of blood-forming cells used in transplants: bone marrow, peripheral blood stem cell or PBSC and umbilical cord blood collected after a baby is born.
The peripheral blood stem cell donation is a painless, non-surgical, outpatient procedure that involves only a needle in the arm vein, similar to platelet donation. However, if a marrow is requested, then it is a surgical procedure.

Study shows adipose stem cells may be the cell of choice for therapeutic applications – Medical Xpress
By JoanneRUSSELL25
February 24, 2017
An international team of researchers, funded by Morris Animal Foundation, has shown that adipose (fat) stem cells might be the preferred stem cell type for use in canine therapeutic applications, including orthopedic diseases and injury.
Researchers at the University of Guelph, University of Western Ontario and Aarhus University, Denmark, ran a battery of tests comparing the physiology characteristics of stem cells derived from adipose tissue versus bone marrow. They found that stem cells from both sources had similar functional properties, including tissue generation and immunomodulating capabilities (ability to adjust immune response), but adipose stem cells grow at a faster rate than bone marrow stem cells. Harvesting adipose stem cells also is less invasive than harvesting bone marrow. The study recently was published in PLoS ONE, an online scientific journal.
In the last decade, the use of stem cell therapy in animals and humans has dramatically increased. In dogs, stem cell therapy is used in the treatment of a variety of orthopedic diseases and injuries. Stem cells are harvested from either fat tissue or bone marrow, purified and grown in culture, then placed back in the patient.
Given the ease of harvesting, adipose tissue has become the site of most stem cell collections in canine patients. But questions persisted regarding the differences between these two sources of stem cells, and which is better suited to therapeutic applications.
"Faster proliferation along with the potential for a less invasive method of their procurement makes them (adipose stem cells) the preferred source for canine mesenchymal stem cells," concluded the research team.

Blood donation system enough to protect blood stem cell donors – India.com
By JoanneRUSSELL25
Kolkata, Feb 23 (PTI) India does not require any specific policy for blood stem cell donations as the existing blood donation system was enough to protect the donors and recipients, a senior doctor said today.
I dont think we need any more (policy) for blood stem cell donation than the one which exists in the current blood banking system to protect the donor and the patient. I dont think more legislation is needed because that will complicate things more, Dr Mammen Chandy, director Tata Memorial Centre, Kolkata said today.
Stating that bone marrow transplantation is the last choice for treating a patient suffering from fatal blood disorders like blood cancer and thalassemia, Dr Chandy rubbished claims of any malpractice in the country relating to bone marrow donation.
Transplantation is the last choice because its not that simple And I dont think there is any malpractice in India currently in relation to bone marrow donation. This may not be true with organ transplantation but certainly there is no unethical practice regarding bone marrow transplantation in any of the sectors, he stated.
On whether there is a need for a law on this matter, the doctor said that the existing rules and regulations were adequate at the moment.
Because here there is nothing involved in it because you are donating something like blood. I think the existing rules and regulations are adequate at the moment, Dr Chandy said.
Cost of bone marrow transplantation is obviously a matter of concern, he said.
On whether there is a need for a policy to keep a control on the expenses involved in transplantation, he said, Cost is obviously a major problem. I dont think that there is anything other than the intrinsic costs of the drugs, the facilities that are required which make this such an expensive procedure

Stem Cell Treatments Could Be The Next Frontier In Fixing Broken … – Deadspin
By JoanneRUSSELL25
In an interesting dispatch from spring training, Yahoos Jeff Passan reports on Los Angeles Angels pitcher Garrett Richardss recovery from a May 2016 elbow injury that shut him down for the season.
Instead of electing to undergo standard Tommy John surgery, Richards decided to try to heal his injury by getting an injection of stem cells directly into his elbow. Passan, whose 2016 book The Arm showed hes not afraid to make his readers feel queasy, described the procedure as such: Richards was fortunate to only suffer a partial tear, which is naturally easier to repair than a full tear.
A doctor guided a needle into the iliac crest of his pelvic bone and began to extract bone marrow.
[...]
Within a few minutes, the harvested marrow was hurried to a centrifuge, spun to separate the good stuff, mixed into a slurry of platelet-rich plasma and readied to inject into Richards damaged right elbow.
Gross, but it apparently worked. Passan reports Richards is feeling great and throwing 98 mph at spring training. Richards is clearly pleased with the tentatively positive outcome: Science, bro. Im a believer now, Richards told Passan.
Dr. Neal ElAttrache, sports premiere orthopedic surgeon, says he is looking forward to seeing where the research on the efficacy of orthobiologics goes, but he also has a theory that the simple resting of the muscle could be the impetus for muscle repair. Or, at least, that the two factors combined can be effective.
A stem cell procedure is less invasive than UCL surgery, of course, and right now it looks like the healing process could be much shorter than that of Tommy John surgery, at least for pitchers with partial UCL tears. Standard TJ recovery time is 14 monthsnearly long enough to inspire an oh yeah, that guy reaction when the player eventually returns. Richards underwent his stem cell procedure in May 2016 and Passan reports that he was throwing by August and was ready to go by October.
Richards will, of course, be kept on a short leash this season as he and the Angels look to avoid a setback or worse, but the potential for an expedited return from partial UCL tears is a major development for the science of pitching.
If stem cell treatments can get electric pitchers like Richards healed and back on the field quicker than surgery can, thats obviously a good thing for baseball. Still, its hard to read Passans story and not come away from it asking, Whats a PED again? Heres Richards talking about his stem cell treatment in the Los Angeles Timesback in 2016:
Stem cells are a remarkable thing. The body heals itself, so thats awesome. Were not out of the woods yet, but todays a good day.
HGH doesnt exactly work the same way this stem cell treatment appears to, but their essential benefits are the same. While the term performance enhancing drugs is still commonly associated with the mega-roids 1990s, HGH is of value to athletes largely for its ability to quicken injury recovery and extend careers. Doctors pushing orthobiologics experiments on their patients are free of the whiff of impropriety, but it seems that has less to do with their virtue than it does their good fortune at being on the right side of baseballs arbitrary PED laws.

Neurons Signal Spinal Cord Vascularisation – Technology Networks (press release) (registration) (blog)
By JoanneRUSSELL25
Severely hyperbranched vascular network surrounding the spinal cord (red dotted box) of zebrafish embryo blood vessels in white.
A team of researchers at Karlsruhe Institute of Technology (KIT) shake at the foundations of a dogma of cell biology. By detailed series of experiments, they proved that blood vessel growth is modulated by neurons and not, as assumed so far, through a control mechanism of the vessel cells among each other. The results are groundbreaking for research into and treatment of vascular diseases, tumors, and neurodegenerative diseases. The study will be published in the journal Nature Communications.
Our work is pure basic research, Professor Ferdinand le Noble of KITs Zoological Institute says, but provides a completely new perspective on how blood vessels grow, branch out, or are inhibited in their growth. For decades, researchers have been looking for ways to promote or impede the formation of new blood vessels. Whereas heart attack and stroke patients would profit from new arteries, cancer patients would benefit from tumor starving by putting a stop to ingrowing blood vessels.
The key figures in the newly discovered extremely finely balanced process are signaling molecules: the brake on growth soluble FMS-like tyrosine kinase-1, referred to as 1sFlt1, and the vascular endothelial growth factor, referred to as VEGF. Even though, so far, it has been largely unknown how VEGF is regulated by the body, inhibition of this growth factor has been applied for years already in the treatment of cancer patients and of certain eye diseases. The therapy, however, is successful only in part of the patients and has several undesired side effects.
So far, research assumed the blood vessels to more or less regulate their own growth, explains le Noble. In case of oxygen deficiency, he points out, tissue, among others, releases the growth factor VEGF, thus attracting the blood vessels carrying VEGF receptors on their surfaces. We wanted to know how this blood vessel growth is regulated at the time of a creatures birth. The team around le Noble hence studied the continuous growth of nerve tracts and circulatory vessels in zebrafish model organisms. The eggs of zebrafish are transparent and develop outside of the mothers body, allowing researchers to watch and observe the development of organs or even individual cells without injuring the growing animal.
By means of fluorescent dyes, postgraduate Raphael Wild in a first step documented colonization of neuronal stem cells and subsequent vascular budding in the vertebral canal of zebrafish. To understand the exact process, the team started a detailed biochemical and genetic analysis.
The researchers proved that at different development stages, the nerve cells of the spinal cord produce more or less sFlt1 and VEGF and, in this way, modulate the development of blood vessels. At the early development stage, neuronal sFlt1 brakes blood vessel growth by binding and inactivating the growth factor VEGF. In the spinal cord, this creates an environment poor in oxygen, which is essential to the early development of the neuronal stem cells. With increasing nerve cell differentiation, concentration of the soluble sFlt1 decreases continuously, and the brake on vascular growth is loosened because more active VEGF is now available. Subsequently, blood vessels grow into the young spinal cord to provide it with oxygen and nutrients.
In addition, Raphael Wild and his colleague Alina Klems show that the concentration of the growth factor is crucial as regards the density of the developing blood vessel network. Whereas, when the brake sFlt1 in nerve cells was switched off completely, a dense network of blood vessels formed which even grew into the vertebral canal, the growth of blood vessels was suppressed when sFIt1 was increased. Even small variations in substance concentration thus led to severe vascular developmental disorders.
Since vascular cells also have own forms of sFlt1 and VEGF, the question arose as to whether blood vessel growth may, to a certain degree, regulate itself. To find out, the researchers applied the still young and extremely elegant CRISPR/Cas method: Whereas there was no effect when sFlt1 was switched off only in vascular cells, an intensive growth of blood vessels was observed when the production of sFlt1 was switched off in the nerve cells only.
From the results we conclude that by a fine modulation of sFlt1 and VEGF, nerve cells very dynamically regulate the density of their blood vessel network according to requirements or according to the respective development stage, le Noble points out. The previous assumption that growing blood vessel cells control the succeeding vascular cells is a cell biology dogma whose foundations are being shaken.

How researchers in Vail are pursuing breakthroughs to help injuries heal faster and some day slow down the way … – The Denver Post
By JoanneRUSSELL25
VAIL Hallways at the world-famous Steadman Clinic are lined with framed, autographed jerseys of star athletes who have had surgery here, including John Elway, Mario Lemieux and Alex Rodriguez.
The clinic and its associated Steadman Philippon Research Institute (SPRI) attract world-class talent from all fields including U2 drummer Larry Mullen Jr., who joined the institutes board after he was a patient here but perhaps its top recruit was a renowned scientist researching ways to help injuries heal faster and slow down the way our bodies age.
Were trying to develop the iPhone 9 of medicine, said Dr. Johnny Huard, chief scientific officer and director of the institutes Center for Regenerative Sports Medicine. Your iPhone 6 and 7 are great, its doing everything you want, but youre looking on the web at what the iPhone 8s going to do. We want to have surgeons here doing surgery on our best football, hockey, basketball players, and instead of losing a year to heal, can we heal them in six months? Three months? Would that be great?
Joe Amon, The Denver Post
The field is called biologics, and its transforming orthopedics by using cells that heal produced in the patients body in concentrated injections that can hasten tissue repair directly at the site of the injury. Huard is leading cutting-edge research into stem cells and platelet-rich plasma (PRP) therapy that he believes will some day delay age-related diseases and cut the recovery time from serious injuries, such as to the knee, in half.
Stem cells are undifferentiated cells that can become specialized cells muscle, bone, cartilage to help repair tissue. Platelets carry proteins that help in the healing process. The breakthroughs Huard and his colleagues are pursuing hold exciting promise for weekend warriors as well as for star athletes.
I dont think we can reverse aging, but I think we can age better and recover from injury better, said Dr. Marc Philippon, managing partner of the Steadman Clinic and co-chairman of the research institute. As a surgeon my biggest challenge is, if I cut on you theres always that healing phase. We want to recover faster. But the most important thing is prevention of injury. If your cells are aging better, youll have less injury. The way I look at it, thats going to put us out of business, but thats OK. Its a good way to go out of business.
A world-class scientist, Huard discovered muscle-derived stem cells in 1998. Before joining SPRI two years ago he was the director of the Stem Cell Research Center at the University of Pittsburgh.Researchers here believe injections of stem cells and PRP can help delay or prevent the need for joint replacements, and at the adjacent clinic they can test their theories in clinical trials. They have shown in animal studies that young stem cells can rejuvenate old stem cells.
To that end Huard advocates passionately that when a child is born, stem cells from the umbilical cord should be harvested and frozen at minus-80 degrees Fahrenheit. As bodies age, stem cells diminish in number and vitality, but they can be preserved in suspended animation while frozen. Those cells later can be thawed and reintroduced into the body as younger and more robust stem cells than the ones that have aged in the patient, performing like a fountain of youth.
Thats the best gift you can give to that baby, said Huard, a French Canadian with a playful wit. Its the best gift you can give to that mother, too, because that (umbilical cord) is part of her, too. Its not only part of the baby. Can you believe the impact of that?
Stem cells, aging and exercise
Because stem cells can develop into every cell type in the body, researchers believe they can be used to hasten repair of nerves, bone and muscle. Bone marrow transplants are the most common form of stem cell therapy currently in use, but stem cells may be useful in fighting neurodegenerative diseases and other conditions.
We can use them to repair bone, cartilage, the heart, the bladder, Huard said. We have clinical trials now ongoing for bladder and the heart.
Imagine a Broncos running back blowing out his anterior cruciate ligament in training camp but being able to return to the field during the regular season. Huardforesees that day, as well as a time when patients whose stem cells were harvested and stored at birth will be able to have them injected into their knees decades later after ACL repair, for example, which theoretically could allow the person to recover much faster.
If I harvest stem cells from your muscle today, lets say I find 100 stem cells, but if I do the same thing 30 years ago I may have gotten 10,000, Huard said. Not only that, but the 100 stem cells you have are tired. They have been dividing and trying to repair your muscle.
When one of Huards children was born 17 years ago and it came time for Huard to cut the umbilical cord, he asked the nurse what they were going to do with it.
My wife said, Can you stop being a scientist and be my husband for a minute here? Huard tells the story with amusement, but he is passionate that umbilical cord stem cells should be saved.
I tell people, No more flowers, just freeze the stem cells from that newborn, Huard said. Thats the best gift you can give to that kid.
In the meantime, Huard believes exercise remains the best anti-aging mitigation we have. Beyond the benefits already well known, he is convinced exercise increases the production of stem cells and delays the aging process.Researchers found that mice that run on treadmills heal significantly faster than sedentary mice. Mice who exercised also had a better survival rate after being injected with cancer cells than those that were sedentary.
Huardbelieves exercise helps the brain as well as the heart in ways that might not be fully understood but might have implications for the prevention or delay of dementia and Alzheimers.
Stem cells come from blood vessels, Huard said. What can we do to increase the number of blood vessels? If we can do that, then we can probably improve tissue repair. If you exercise, you increase the number of blood vessels in your tissues.
Platelet-rich plasma therapy
PRP therapy is already in widespread use, not just in elite athletes but in recreational athletes as well. Sometimes it works well, and sometimes it doesnt work at all. Huard is trying to find out why.
Platelets in the blood carry proteins called growth factors that help the body repair injured tissue. In PRP therapy, a patients blood is removed and spun in an centrifuge or filtered to separate platelets. Then the platelet-rich plasma is injected into the site of an injury with hopes of speeding the healing process.
When you injure something, you bleed, Philippon said in his office with a view of Vails ski trails. Some of the first elements going there are your platelets, and theres a reason for that. Platelets have the growth factors, also what we call the chemotactic factors, to attract whats needed (to heal).
Philippon has used PRP to hasten healing of hip tendons in football players, for example.
What we found was that those I injected with PRP early recovered faster, Philippon said. We have that data here. We know, for a tendon injury, PRP is a great therapy.
Huard had elbow surgery last year after snapping a tendon off the bone in a ski accident I like to go fast, he said with a grin and Steadman surgeon Peter Millett asked Huard if he wanted a PRP injection in hopes of hastening recovery.
I said, Of course! You know what? I never wore a sling, Huard said. The week after, I was running. Three weeks after, I was back skiing.
But did the PRP help?
I dont know, Huard said.
So Huard is studying the success rate of PRP therapy in patients who receive it after surgery at the Steadman Clinic. When Philippon uses PRP on a patient, for example, he will set aside a fraction of that PRP and give it to Huard to analyze in the lab. Huard will catalog the different growth factors in each sample and then wait to see how the patients respond.
After this Im going to go back to Marc and say: Which patient worked? Which one was your best patient? Huard said. If he tells me patient No. 24 and 32 and 48, Im going to go back and try to see what those three patients PRP had in common in terms of growth factors.
Then Huard will be able to better advise surgeons before using PRP.
Lets say we find when IGF1 (insulin growth factor one) is high in your blood, PRP always works, Huard said. You know what Im going to give to those surgeons? Im going to say, Before you give PRP, take a blood draw, we go in the lab, test for IGF1, and if IGF1 is high, 95 percent chance PRP is going to help. But another patient, if IGF1 is not high, Based on our tests, I dont think PRP is going to help.
Another thing we found in PRP, it is a mixed bag. You have good things in PRP but you have bad things, too. So were doing science where Im going to take PRP, Im going to take out the bad guys.
As with stem cells, Huard foresees a day when a young patients PRP can be frozen and used decades later to delay aging, administered in conjunction with stem cell injections to work in synergy.
I think the two can be combined somehow, Huard said. They are different, but the stem-cell therapy and the PRP somehow can be together. If I have your PRP from 20 years ago and I have your stem cells from 20 years ago, I can make a very nice mixture, inject this into you. Sometimes adding one thing to another, biologically, it equals not two but three.
Having his laboratory in the same building as the Steadman Clinic, which has eight surgeons on staff, is a boon for Huard in his research. He takes ideas to them and vice versa.
I dont do science just to do science, he said. I do science to improve quality of life, and I think I can make a major contribution in the field. If you delay aging by 10 years, you delay all those age-related disorders by 10 years. The implications for health care is amazing.
Biologics: Using tools produced by a patients body such as stem cells and platelet-rich plasma (PRP) to help the patient heal faster and better.
Regenerative medicine: This and tissue engineering are promising treatment approaches that can enhance or promote musculoskeletal tissue healing and regeneration following surgery or injection therapy. Biological treatments such as growth factor supplementation, PRP and bone marrow concentrate have been shown to improve patient function and quality of life.
Platelet-rich plasma: A biologic treatment that is produced by concentrating the patients own blood to yield a high platelet count. Platelets are important blood components that secrete hundreds to thousands of biological factors that initiate musculoskeletal tissue healing and regeneration.
Stem cells: Stem cells have the ability to transform into specific musculoskeletal tissue cells. These types of cells also secrete biological factors that initiate musculoskeletal tissue healing and regeneration. There are several forms of stem cells, such as muscle-derived stem cells, bone marrow-derived stem cells, adipose-derived stem cells and others.
