Ribosomes, which build a protein (black) from an RNA strand (blue), may specialize in making particular sets of proteins.

The plant that built your computer isn't churning out cars and toys as well. But many researchers think cells' crucial protein factories, organelles known as ribosomes, are interchangeable, each one able to make any of the body's proteins. Now, a provocative study suggests that some ribosomes, like modern factories, specialize to manufacture only certain products. Such tailored ribosomes could provide a cell with another way to control which proteins it generates. They could also help explain the puzzling symptoms of certain diseases, which might arise when particular ribosomes are defective.

Biologists have long debated whether ribosomes specialize, and some remain unconvinced by the new work. But other researchers say they are sold on the finding, which relied on sophisticated analytical techniques. "This is really an important step in redefining how we think about this central player in molecular biology," says Jonathan Dinman, a molecular biologist at the University of Maryland in College Park.

A mammalian cell may harbor as many as 10 million ribosomes, and it can devote up to 60% of its energy to constructing them from RNA and 80 different types of proteins. Although ribosomes are costly, they are essential for translating the genetic code, carried in messenger RNA (mRNA) molecules, into all the proteins the cell needs. "Life evolved around the ribosome," Dinman says.

The standard view has been that a ribosome doesn't play favorites with mRNAsand therefore can synthesize every protein variety. But for decades, some researchers have reported hints of customized ribosomes. For example, molecular and developmental biologist Maria Barna of Stanford University in Palo Alto, California, and colleagues reported in 2011 that mice with too little of one ribosome protein have short tails, sprout extra ribs, and display other anatomical defects. That pattern of abnormalities suggested that the protein shortage had crippled ribosomes specialized for manufacturing proteins key to embryonic development.

Definitive evidence for such differences has been elusive, however. "It's been a really hard field to make progress in," says structural and systems biologist Jamie Cate of the University of California (UC), Berkeley. For one thing, he says, measuring the concentrations of proteins in naturally occurring ribosomes has been difficult.

In their latest study, published online last week in Molecular Cell, Barna and her team determined the abundances of various ribosome proteins with a method known as selected reaction monitoring, which depends on a type of mass spectrometry, a technique for sorting molecules by their weight. When the researchers analyzed 15 ribosomal proteins in mouse embryonic stem cells, they found that nine of the proteins were equally common in all ribosomes. However, four were absent from 30% to 40% of the organelles, suggesting that those ribosomes were distinctive. Among 76 ribosome proteins the scientists measured with another mass spectrometry-based method, seven varied enough to indicate ribosome specialization.

Barna and colleagues then asked whether they could identify the proteins that the seemingly distinctive ribosomes made. A technique called ribosome profiling enabled them to pinpoint which mRNAs the organelles were readingand thus determine their end products. The specialized ribosomes often concentrated on proteins that worked together to perform particular tasks. One type of ribosome built several proteins that control growth, for example. A second type churned out all the proteins that allow cells to use vitamin B12, an essential molecule for metabolism. That each ribosome focused on proteins crucial for a certain function took the team by surprise, Barna says. "I don't think any of us would have expected this."

Ribosome specialization could explain the symptoms of several rare diseases, known as ribosomopathies, in which the organelles are defective. In Diamond-Blackfan anemia, for instance, the bone marrow that generates new blood cells is faulty, but patients also often have birth defects such as a small head and misshapen or missing thumbs. These seemingly unconnected abnormalities might have a single cause, the researchers suggest, if the cells that spawn these different parts of the body during embryonic development carry the same specialized ribosomes.

Normal cells might be able to dial protein production up or down by adjusting the numbers of these specialized factories, providing "a new layer of control of gene expression," Barna says. Why cells need another mechanism for controlling gene activity isn't clear, says Cate, but it could help keep cells stable if their environment changes.

He and Dinman say the use of "state-of-the-art tools" makes the results from Barna's team compelling. However, molecular biologist Harry Noller of UC Santa Cruz doubts that cells would evolve to reshuffle the array of proteins in the organelles. "The ribosome is very expensive to synthesize for the cell," he says. If cells are going to tailor their ribosomes, "the cheaper way to do it" would entail modifying a universal ribosome structure rather than building custom ones.

A cancer survivor and transplant athlete from Warwick has issued a fresh plea for people to sign up to be an organ donor as he heads off to Malaga for the World Transplant Games.

Simon Perkin was diagnosed with blood cancer in 1991 at the age of 26 and after years of treatment and his deteriorating health, was left with no alternative but to have a bone marrow transplant in July 2012, when a donor match was found.

Since the operation, Simons health has steadily improved.

A major part of his recovery has been keeping himself in the best possible shape, which included taking part in the London Marathon just 18 months after his transplant.

In July 2016 Simon took part in the British Transplant Games in Liverpool, which is a qualifier for the World Transplant Games, where he won four gold medals.

Simon was selected for Team GB at this years World Transplant Games, and is part of the countrys largest ever team at the event, with 200 transplant athletes, including 20 juniors, 10 live donors, and 200-plus supporters.

The Games take place every two years, this year starting on the 25 June, and are supported by the International Olympic Committee.

They represent the largest organ donor awareness event in the world, featuring a week of 17 sporting events, 1000 transplant athletes, from 60 countries across the globe.

All of Team GBs athletes have survived either a heart, lung, kidney, pancreas, liver, small bowel or bone marrow transplant.

Simon has now launched a fresh plea to get more people to sign up to the Organ Donation Register.

He said: Every twenty minutes someone in the UK finds out they have a blood cancer.

Around 2,000 people in the UK are in need of a bone marrow or stem cell transplant every year. Like me, this is usually their last chance of survival

I was diagnosed with blood cancer in 1991 at the age of 26 and after years of treatment and deteriorating health, my only option was a bone marrow transplant. I was lucky as the Anthony Nolan Trust found a donor match in July 2012, and so my recovery began.

As training for the World Transplant Games enters its final phase, its a reminder of how far I have come and all I have achieved. It makes me feel so proud to be alive and representing Team GB at the Games.

To cover his own costs of getting to the World Transplant Games and raise money for Transplant Sport UK, Simon has launched a fundraising campaign that has so far, raised 2,030 of his of 2,500 target.

Warwickshire law firm Lodders has already donated 600 to Simons fundraising, making it his largest supporter to date.

Lynne Holt, Team GB Manager added: In spite of the constant training, fitting in work, school, exams, and hospital clinic appointments, these athletes receive no government support, and have to raise the funding themselves.

Sadly, many could not accept their place on the team, because of the heavy financial burden.

The team are supported by management, coaches, captains and a medical/physio team, all who are volunteers and are also self-financing.

Their motivation to be Fit for Life, the opportunity to represent their country, celebrate life and pay tribute to their donors who gave them life, is the goal.

These athletes certainly deserve the same recognition as the recent Olympic and Para Olympic Games. Not only are they ambassadors for our country, but they are also representing the charity, Transplant Sport, and hope to raise awareness here in the UK and globally, of the need for more people to sign on to the Organ Donor Register and discuss their wishes with their family and friends.

Scientists at the Broad Institute of MIT and Harvard have found that a set of genetic mutations in blood cells that arises during aging may be a major new risk factor for cardiovascular disease. In contrast to inherited genetic predispositions and traditional lifestyle risk factors, such as smoking or an unhealthy diet, the new mutations are "somatic mutations" that originate in stem cells in the bone marrow as people age.

Because the mutations are relatively common in older people (over 10% of people over the age of 70 harbor at least one of these mutations), potential future efforts to screen for the mutations in blood cells, identify people at increased risk for coronary heart disease, and reduce risk in those individuals through lifestyle changes or therapeutic interventions could have a significant clinical impact, according to the researchers.

"There is more work to be done, but these results demonstrate that pre-malignant mutations in blood cells are a major cause of cardiovascular disease that in the future may be treatable either with standard therapies or new therapeutic strategies based on these findings," said Benjamin Ebert, a co-senior author of the new study, an institute member at the Broad, a professor of medicine at Harvard Medical School, and a hematologist at Brigham and Women's Hospital.

Featured in the New England Journal of Medicine, the work also contributes to the broader understanding of pathogenesis in coronary heart disease by supporting the hypothesis that inflammation, in addition to elevated cholesterol levels, plays an important role in this illness and potentially other diseases of aging.

"A key finding from this study is that somatic mutations are actually modulating risk for a common disease, something we haven't seen other than in cancer," said first author Siddhartha Jaiswal, a pathologist at Massachusetts General Hospital and researcher in the Ebert lab. "It opens up interesting questions about other diseases of aging in which acquired mutations, in addition to lifestyle and inherited factors, could modulate disease risk."

Previous research led by Ebert and Jaiswal revealed that some somatic mutations that are able to confer a selective advantage to blood stem cells become much more frequent with aging. They named this condition "clonal hematopoiesis of indeterminate potential," (CHIP), and found that it increases the risk of developing a blood cancer more than 10-fold and it appeared to increase mortality from heart attacks or stroke. In the new study, the researchers analyzed data from four case-control studies on more than 8,000 people and found that having one of the CHIP-related mutations nearly doubled the risk for coronary heart disease, with the mutations conferring an even greater risk in people who have previously had a heart attack before age 50.

While the human genetics data showed a strong association between CHIP and coronary heart disease, the team hoped to uncover the underlying biology. Using a mouse model prone to developing atherosclerosis, the scientists showed that loss of one of the CHIP-mutated genes, Tet2, in bone marrow cells leads to larger atherosclerotic plaques in blood vessels, evidence that this mutation can accelerate atherosclerosis in mice.

Atherosclerosis is believed to be a disease of chronic inflammation that can arise in response to excess cholesterol in the vessel wall. To examine this on a cellular level the team turned to the macrophage, an immune cell found in atherosclerotic plaques that can develop from CHIP stem cells and carry the same mutations. Because Tet2 and other CHIP-related mutations are known to be so-called "epigenetic regulators" that can alter the activity of other genes, the team examined gene expression levels in the Tet2-mutated macrophages from mice. They found that the mutated cells appear to be "hyper-inflammatory" with increased expression of inflammatory molecules that contribute to atherosclerosis. In support of this finding, humans with TET2 mutations also had higher levels of one of these molecules, IL-8, in their blood.

The work demonstrates that CHIP associates with coronary heart disease in humans, that mutation of the CHIP-related gene Tet2 causes atherosclerosis in mice, and that an inflammatory mechanism likely underlies the process. More work is needed to show whether other genes that are mutated in CHIP also lead to increased inflammation. The team is also exploring whether interventions such as cholesterol lowering therapy or anti-inflammatory drugs might have benefit in people with CHIP.

Inflammation is also thought to modulate several other diseases of aging besides cardiovascular disease, such as autoimmune disorders and neurodegenerative disease. Because CHIP also increases in frequency with age, somatic mutations that alter inflammatory processes could influence several diseases of aging, though more work is needed to test this possibility.

"By combining genetic analysis on large cohorts with disease model and gene expression studies, we've been able to confirm the earlier hints of CHIP's surprising role in cardiovascular disease," said co-senior author Sekar Kathiresan, director of the Broad's Cardiovascular Disease Initiative, associate professor of medicine at Harvard Medical School, and director of the Center for Genomic Medicine at Massachusetts General Hospital. "Beyond the mutations that you inherit from your parents, this work reveals a new genetic mechanism for atherosclerosismutations in blood stem cells that arise with aging."

Aging-related mutations in blood cells represent major new risk factor for cardiovascular disease - Medical Xpress

Bone Marrow Stem Cells Comments Off on Aging-related mutations in blood cells represent major new risk factor for cardiovascular disease – Medical Xpress | June 22nd, 2017

Matthew Medinas doctors diagnosed him with a rare blood disease a few months ago and told him he would probably die without a bone marrow transplant.

With that prognosis came another: The 40-year-old Los Angeles police officer had a less than 50% chance of finding a donor because he is not white.

Most successful matches for bone marrow transplants involve a donor and patient of the same ethnicity. But the majority of the 25 million registered donors nationwide are white, and Medina is Filipino. So far, no match has been found.

Youre basically looking for a genetic twin, said Athena Mari Asklipiadis, who runs Mixed Marrow, an L.A.-based organization that is trying to increase diversity in the bone marrow donor registry. Its not like we have more of a chance we would get a disease, or that were harder to match, its just that theres not representation in the national registry.

Its a familiar problem for any nonwhite person who has needed a bone marrow transplant.

A white American of European descent has a 75% chance of finding a perfect match in the national donor registry, compared with a 40% chance for Filipinos. Few Filipinos in the U.S. have signed up as potential donors, and there is no registry in the Philippines.

Researchers are experimenting with ways to perform bone marrow transplants on people who cant find matches. But while those treatments are being perfected, thousands of people are diagnosed every year with leukemia, lymphomas and other blood diseases whose only hope for a cure is a marrow transplant. And for them, it can come down to ethnicity.

Medinas wife, Angelee, has watched dozens of people at sign-up events across Southern California, particularly in the Filipino community, volunteer to donate bone marrow with the hope of curing her husband. Were very thankful for that, she said. Were hoping something comes up.

For now, Medina is being kept alive with transfusions.

All you want is for that loved one to have a chance, said Officer Dante Pagulayan, Medinas partner at the LAPD and a childhood friend. Thats what were praying for.

Medina went to the doctor in March because he had a rash. His blood work revealed something far more dangerous.

Medina was diagnosed with aplastic anemia, a disease in which the bone marrow stops working. Bone marrow is spongy material inside bones that produces the essential components of blood white blood cells, red blood cells and platelets.

Between 600 and 900 Americans are diagnosed with aplastic anemia each year, according to the Aplastic Anemia and MDS International Foundation. The disease can be caused by exposure to toxic chemicals or a virus, but most cases, including Medinas, are unexplained.

One day he wakes up and the doctor tells him he has this. It could happen to anyone, said Pagulayan, who went to high school and Cal State Long Beach with Medina and now works alongside him in the gang unit in the LAPDs Harbor Division.

Blood transfusions can sustain Medina for now, but the only possible cure for aplastic anemia is a transplant, said Dr. Len Farol, a bone marrow transplant specialist at City of Hope National Medical Center and one of Medinas physicians.

Medina is quarantined at his home in Bellflower, where he lives with his wife and two young daughters. But he needs a transplant soon because his immune system is so weakened from his disease that exposure to a common virus could kill him, Farol said.

Doctors checked to see if Medinas sister could be a match, but she wasnt siblings provide a match only about 25% of the time. They started combing through the registry, but trying to find a donor there can be like finding a needle in a haystack, Farol said.

Doctors look to see if the patient and potential donor share eight cell markers called human leukocyte antigens, or HLA. All eight have to match, but thats rare because there are thousands of possibilities for each marker, experts say.

There could be billions of combinations, said Stephen Spellman, director of immunobiology and observational research for the Center for International Blood and Marrow Transplant Research. Within any group, finding a match for HLA is difficult.

Spellman said that people whose ancestors are from the same place tend to have the same markers because they evolved over time in response to different pathogens and diseases that were present in their environment.

According to a 2014 report in the New England Journal of Medicine, a person of white European descent has the highest chance of finding a perfect match eight out of eight HLA markers in the national registry of any ethnic group.

What's your chance of finding a perfect match? If you're...

Pagulayan, who is also Filipino, said neither he nor Medina knew ethnicity would affect his chances of being cured. Finding out that less than 1% of people in the registry were Filipino was very disheartening, he said.

There are international registries, but the vast majority of people worldwide whove signed up to donate bone marrow are from the U.S and Europe.

Plus, nonwhite populations in general tend to have more genetic diversity. African Americans, for example, have highly diverse genetics because of mixing with other groups since arriving in the United States, experts say. Filipinos are also very diverse because of the countrys long history of colonization.

Still, experts say that everyone who wants to help Medina should sign up for the registry, regardless of ethnicity.

Matches often break down along ethnic lines, but not always. Sometimes markers in one population also appear in another, or people dont know their lineage.

Maya Chamberlin, who is half Indian and half white, had two bone marrow transplants after she was diagnosed with a rare blood disease called HLH in 2009 when she was 4.

Mayas first donor was half Japanese and half Latino, and her second was half Japanese and half Filipino.

So you never know how this works until you get on the registry, said her mother, Mina Chamberlin, who lived in Torrance when Maya was diagnosed but has since relocated to Cincinnati to be closer to physicians who specialize in her daughters disease. You just never know.

Angelee Medina canceled her familys vacation to Mexico scheduled for this summer. Shed been commuting to a job as a graphic designer 20 miles from home when Matt was diagnosed, but found a closer place to work so she could take care of the kids and be near her husband.

It was very, very overwhelming in the beginning, she said. With all the support were getting from everyone around us, it feels hopeful.

More than 1,000 people have signed up to donate bone marrow over the past few months through dozens of drives for Medina, said Chris Chen, a recruitment coordinator for Little Tokyo-based nonprofit A3M, which focuses on getting more Asians to sign up for the Be the Match registry to donate bone marrow.

Potential donors submit cell samples by having the inside of their cheek swabbed. The cells are then analyzed to determine their HLA markers.

About 70% of transplants employ a process called peripheral blood stem cell donation, which is similar to a blood donation but can take several hours. In the other 30% of cases, donors are admitted to the hospital and anesthetized so doctors can remove marrow from their pelvic bone with a needle.

Ayumi Nagata, recruitment manager for A3M, knows that asking people to volunteer for a medical procedure they dont need themselves can be a hard sell. But she tries to impress upon them how they could be the cure for someones cancer or other disease and save their life.

How often do we have that kind of opportunity? Nagata said.

The Medinas 8-year-old daughter, Cassiah, made a sticker thats distributed at donor drives that says, Keep calm and help our daddy fight! When Angelee picked up Cassiah from day care recently, she found out that her daughter had been asking the other kids parents: Did you get swabbed? Have you gotten swabbed yet?

Doctors are testing ways to perform transplants on patients who cant find a bone marrow match. Some are using umbilical cord blood, donated by mothers whove just given birth, which scientists say has a lower chance of rejection even if its not a complete match.

Haploidentical transplants, in which the donor and patient share only half of the eight markers, have also been successful in clinical trials, Spellman said.

Medinas doctors think his best shot is still a perfect match for a bone marrow transplant, his wife said.

Thats just what were waiting for, she said. I remind him one day soon, hopefully everything will be better.

Founded in 2004, LifeCcell has technological collaboration with the US-based Cryo-Cell Internationalthe worlds first private stem cell bank with over 25 years of experience. (PTI)

Chennai-based LifeCell, the provider of preventive healthcare services for family wellness, is the worlds second-largest provider of umbilical cord stem cells. Founded in 2004, the company has technological collaboration with the US-based Cryo-Cell Internationalthe worlds first private stem cell bank with over 25 years of experience. As many as 2 lakh Indian parents have chosen to trust their newborns umbilical cords to LifeCell through its umbilical cord banking service BabyCord. The company has a 60% share in the Indian market.Stem cells are mother cells that have the potential to become any type of cell in the body. One of the main characteristics of stem cells is their ability to self-renew or multiply, while maintaining the potential to develop into other types of cells. These cells can repair and rebuild damaged tissue. The uses of stem cells are still being researched. In fact, stem cell tissues have proved effective in cancer treatment too. The applications have been steadily increasing in the last few years. They have been used for treating wound healing, including diabetic foot ulcers. In a country where concepts like bone marrow donations and stem cell banking are still not widely known, Mayur Abhaya, the CEO and managing director of the company, is betting on these treatments of the future.

The company is the most accredited stem cell bank in the country, with certifications from national and international organisations for standards. It is also the only player in the industry providing comprehensive stem cell solutions, including menstrual stem cell banking, R&D and point-of-care stem cell therapy for orthopaedic and vascular specialities.Mayur has been heading LifeCell since 2008. He comes from the family that set up Shasun Group of companiesthe provider of contract pharmaceutical manufacturing services for global companies. Mayur studied biotechnology in India and the US, and then worked in the US for a year. Before moving to LifeCell, he worked for many years at Shasun Pharmaceuticals, where he led their new product development, intellectual property and licensing initiatives. In 2013, LifeCell International got an investment of Rs35 crore from Helion Venture Partners, an India-focused venture fund, to support its plans of increasing market penetration of stem cell banking in India and enabling the development of novel cell-based therapies.

Also Watch: Mayur says LifeCell currently operates in 150 cities, employing more than 1,500 people. We have given an opportunity to our sales people to become their own bosses. They remain on company rolls and get to enjoy all the company benefit plans, such as insurance and welfare schemes. They grow with the company and also have the opportunity to explore and add non-conflicting products or services to their distribution network and enhance their earnings. These internal franchisees bring 50% of our revenue and it is growing. More than 50 such entrepreneurs have been created.LifeCell recently bought over the stake held by Helion Ventures with borrowings from family-owned firms. Three months ago, it changed its business model. We are introducing an on-demand model for sharing cord blood cells, Mayur says. Parents can let the company know if their babies cord blood cells can be used for other needy patients. Cancer patients cannot be treated with their own stem cells. Patients usually do not have much time. Cord cells can be used even if all the six parameters that are required to transplant tissues do not match. By letting their stem cells be used by others, parents and their children get access to cord blood cellsof the entire cord blood cell bankwhen they are in need. So far, stem cells were banked only for the baby from whom these were removed.

Our inventory will come to the aid of people who do not have babies. We will refund the amount paid for having their babys stem cell stored. The processing fee is Rs17,000 and the storage fee each year is Rs4,000. Mayur says that the worlds largest birthing country has a long way to go to create a viable stem cell bank. We are going to follow the blood bank model and hope to bank 2,50,000 cords, which is the critical amount, he adds. We hope to contribute significantly to the ever-developing scope of transplant medicine. Currently, India is importing cord cells, which are prohibitively expensive. With scale, prices will come down in the country. Parents in India will have higher future access to stem cells than even those enjoyed by patients in advanced countries such as the US. We will have a linkage with global inventory. Earlier this month, LifeCell was invited by AABB (formerly American Association of Blood Banks) to present the concept of Community Stem Cell Banking at the 15th International Cord Blood Symposium held in San Diego, US. In 15 years, it is the only second stem cell bank to present its innovation at such a prestigious global platform.

With a turnover of Rs126 crore, LifeCell is operationally profitable. It has enough cash to run its business, but is yet to make net profits. However, Mayur believes very soon LifeCell will turn profitable, and that this year the number of stem cells brought into the labs will be higher by at least 30%. Mayur has extended LifeCells services to introduce and popularise the concept of essential preventive diagnostics for mothers and babies. BabyShield has been introduced to bring down infant mortality ratio. Addressing gaps in marketplace and with innovative business models, it has established market leadership in newborn screening. It has also acquired a prenatal screening service provider. In India, only 2% babies go through prenatal and newborn screening. Nobody has focused on this. We will also be providing diagnostic medication. Doing this can prevent so many false positives. We are building all this together as a package and are offering it at an affordable price, he says.

Dawson Deschaine passed away on June 10th after a 2-and-a-half year battle with leukemia. He was only 8-years-old.

While most kids try to earn gold stars for their work, Dawson Deschainefelt a little pride every time he earned a bead.

"The Beads of Courage program is these beads that [represent] every poke, every hospital stay, every bone marrow biopsy, every chemotherapy," said Breanna Deschaine, Dawson's mother.

Dawson was diagnosed with leukemia in January 2015 at just 6-years-old. The battle would last two-and-a-half years. It was all Dawson ever knew.

"He mostly knew nurses, doctors, family," said Jason Deschaine, Dawson's father. "He had a lot more adult conversations than kid ones."

Breanna said he was an old soul. He even drank a cup of coffee every morning (decaf, of course).

"They accidentally sent him coffee [instead of hot chocolate] to his room one day," said Breanna.

Now you know an infectious smile like Dawson's comes with some pretty funny stories.

Last August, Nevada County made Dawson an honorary firefighter. They called it 'Dawson Day' with a ceremony and all.

Dawson was given a badge, his own turnouts, and boots. He even got to respond to an injured biker.

"He kept telling the EMTs how to wrap the leg!" said Breanna.

And his firefighter card, he never took for granted.

"He was getting ready to go to clinic one day," said Jason. "He comes back running in the house saying 'I need my ID Card!'...'No no, I need it. Just in case mom gets pulled over, [I can say police officer,] I am with the fire department.

It's reminiscing and laughing about stories like this that keep his family strong and smiling even when it hurts.

"People always ask how we're doing. As you can tell we smile. Dawson would never let us cry in the room," said Breanna.

Dawson's community made sure his last months in this world was full of adventure. Sadly, he got too sick for his Make-A-Wish: to go to Hawaii and swim with dolphins.

On June 10th at 6:05 AM, with his parents and his sister by his side, Dawson passed away.

Even up until his very last moment, he gave his family a thumbs up.

"He couldn't talk very much. Just the thumbs up that he was still good. He was Awesome Dawson," said Breanna, through tears. "It was his signature. No matter what...I told him 'It's OK Dawson. You fought the hardest battle and you won.'"

"You're not supposed to cry!" said Melody, Dawson's grandmother. "He's watching you."

And if Dawson was watching, what would they say?

"I would say thank you, for the opportunity...you pulled our community together and made our family so strong," said Melody. "We all love him very, very much. And miss him."

Breanna said she would read to him again from his favorite book 'Love You Forever.'

"His favorite saying from his favorite book: 'I love you forever. I like you for always. As long as I'm living, my baby you'll be," said Breanna.

Dawson's family hopes to continue his legacy by bringing the Beads of Courage program that got him through his darkest days into more hospitals.

Donations can be made on the Beads of Couragewebsite, under Dawson's name.

And until they see Dawson again, the family says they'll live by this motto: 'Don't cry because it's over. Smile because it happened.'

That is what Dawson would've wanted.

Asian American Donor Program encourages minorities and mixed heritage to join national registry

Oakland Lisa Marie Evangelista, a 31-year-old Filipina woman who lives in Sacramento, is in a literal fight for her life. Lisa is a speech language pathologist and works at the U.C. Davis Medical Center.

On Dec. 27, 2016, she was diagnosed with Chronic Myelomonocytic Leukemia, a rare and aggressive blood cancer. She needs a bone marrow transplant to survive. Lisas sister is a 5/10 or half match. However, doctors prefer Lisa find a 10/10-donor match. To find a perfect match, Lisa needs a stranger to step forward and help save her life.

Lisa has partnered with the Asian American Donor Program to find a donor similar to her genetic makeup. A bone marrow transplant, which is needed soon, is Lisas only hope for her long-term survival. A committed 10/10 marrow-matching donor must be located to have a successful transplant. Since Lisa is of Filipino, a matching donor will also need to be of Filipino or Asian descent.

More about Lisa

Lisa learned about her diagnosis just nine months after her father died of a blood cancer. Family and friends note how she brings laughter, joy, warmth, and kindness to each day. Lisa is a speech-language pathologist and board certified specialist in swallowing and swallowing disorders. Her clinical interests include the evaluation and treatment of dysphagia resulting from radiation and chemotherapy treatments to the head and neck. She works directly with patients diagnosed with throat cancer. Lisa has lectured at the regional and national levels on pulmonary health and ethical considerations in dysphagia management. Lisa is described by her colleagues as a brilliant clinician and scientific thinker who is devoted to helping her patients. Lisas hobbies include traveling, hiking, and dancing.

Lisa grew up in Laguna Hills in Orange County, California. She attended Laguna Hills High School. From California State University, FresnoLisa received abachelors degree in 2007 and a masters degree in 2009. Lisa received her clinical science doctorate in medical speech-language pathology from the University of Pittsburgh, Pittsburgh, PA in 2014.

Whats the solution?

Minorities are more likely to die of leukemia and other blood cancers because there is a shortage of ethnic and mixed-ethnic donors on the Be The Match national registry. It is vital to expand and build a more diverse registry so everyone has an equal opportunity to survive blood cancers.

Encouraging more people of ethnically diverse backgrounds and those of mixed heritage to be committed and join the Registry, potentially saving a life. Each of us can Be TheOne to Save a Life!

The Asian American Donor Program (AADP,www.aadp.org) is a 27-year-old nonprofit organization, based in Alameda, CA, that works to educate community members about the shortage of ethnic marrow donors and the importance of joining the Be The Match national registry. It is the oldest nonprofit of its kind in the country. AADP staffis dedicated to increasing the availability of potential stem cell donors for patients with life threatening diseases curable by a blood stem cell or marrow transplant.AADP is an official recruitment center for Be The Match.

There is a shortage of committed non-Caucasians on the Be The Match national registry, says Carol Gillespie, the AADP executive director. We need everyone of mixed race ancestry to step forward and join the Registry.When a marrow match is not readily available, patients have to wait longer than is ideal to find a match.Once a match has been found, their disease may have progressed to the point that they are no longer eligible for a transplant.

Shortage of ethnic/multi-ethnic donors

Approximately every three minutes one person in the United States is diagnosed with a blood cancer. An estimated combined total of 172,910 people in the US are expected to be diagnosed with leukemia, lymphoma or myeloma in 2017. New cases of leukemia, lymphoma and myeloma are expected to account for 10.2 percent of the estimated 1,688,780 new cancer cases diagnosed in the U.S. in 2017. (From:http://www.lls.org/http%3A/llsorg.prod.acquia-sites.com/facts-and-statistics/facts-and-statistics-overview/facts-and-statistics)

Of the approximately 816,000 Asians on the Be the Match registry, .5 percent are Filipinos, while Filipino Americans constitute 19.7 percent of Asian Americans (Source: 2010 Census). The Be The Match registry recruits hundreds of thousands of donors each year through an extensive network of more than 155 local and regional Community Engagement Representatives and organizations. You only need to join the Be The Match registry once.

Finding a marrow/stem cell match can be like finding a needle in a haystack, says Gillespie. Multi-racial patients face the worst odds. Those diagnosed with a blood disease need a marrow/stem cell transplant as soon as possible. Building the Registry with committed donors is what patients need. You could potentially match anyone in the world, this is truly a global effort.

Marrow/stem cell matches are very different than blood type matches. Just as we inherit our eyes, hair, and skin color, we inherit our marrow and stem cell tissue type.

For thousands of severely ill blood cancer patients, there is a cure, Gillespie says. You could be the cure. Those whose marrow/stem cells are not a match for a patient in need now may be a match for someone else down the road, anywhere in the world. I encourage multi-ethnic individuals to commit to registering. It is simple to register just a swab of the inside of your cheek.

Filipina urgently needs bone marrow donor - Asianjournal.com

Bone Marrow Stem Cells Comments Off on Filipina urgently needs bone marrow donor – Asianjournal.com | June 17th, 2017

MUMBAI: Three-year-old Kinaya Shah was diagnosed with thalassemia at the tender age of three months and has been undergoing regular blood transfusions ever since. The only cure for thalassemia is a bone marrow transplant (BMT), a form of stem cell therapy. Typically, the donor of the stem cells would be a sibling of the patient such that the stem cells of the donor are a near perfect match to those of the patient. The only complication was that Kinaya was a lone child.

So, city doctors in a first used stem cells donated by Kinaya's father - who was only a half or haploidentical match - to cure the child of the blood disorder. "We went to Vellore, Bangalore and Pune but no one was willing to do the transplant without a full match donor," said Kinaya's parents, Aneri and Shripal Shah. They approached Dr Santanu Sen at the Kokilaben Dhirubhai Ambani Hospital, Andheri, in October of 2016, after reading about a similar surgery that he had performed.

While haploidentical bone marrow transplants are carried out to cure leukaemia, it has only been done about half a dozen times for thalassemia in a couple of Indian cities. ``Haploidentical transplants are gradually increasing because of better techniques,'' said Dr Sen.

Dr Sen has completed 36 BMTs in the last two years, of which 12 were haploidentical donors. ``But this is the first time that a haploidentical transplant has been done in western India to cure thalassemia,'' he said.

Chennai-based haematologist Dr Revathy Raja said that there is a 85% chance of cure in thalassemia with a fully matched donor. ``The success rate falls to 70% with a half-match or haploidentical donor. We have hence not started it at our Chennai centre. Hopefully, techniques will further improve in the coming years,'' she said.

In order to perform the surgery, Dr Sen conditioned Kinaya's immune system over three months, with slight chemotherapy, to increase the chances of her body accepting the graft. "We found that her father's stem cells were a 70% match through genetic tests and decided to use them for the transplant. In the case that the graft was rejected we froze a couple of Kinaya's stem cells as insurance. The positive is that children have lower rejection rates for foreign cells as they have barely developed any active immunity," said Dr Sen. "BMT is the most viable treatment to cure thalassemia, the only barrier thus far was the necessity of a full match donor," he added.

However, Vinay Shetty of NGO Think Foundation, which works for thalassemia patients, said that it would be prudent to wait for a statistically significant number of successful halploidentical transplants before recommending it to all patients.

Post the three months of conditioning, stem cells were collected from her father's bone marrow and the transplant was performed on May 10, 2017. After several tests to confirm that the graft was accepted, Kinaya was finally discharged from the hospital on June 13.

"The future of thalassemia treatment probably lies in gene therapy, but at the moment, haploidentical transplants have made BMT much more accessible," said Dr Sen, adding that he has two more cases such as Kinaya lined up. Kinaya is expected to be completely independent of medication and any trace of thalassemia in the coming six months.

What is Thalassemia?

Thalassemia is a genetic blood disorder when the body produces abnormal hemoglobin. Patients require regular blood transplant and well as dietary control to ensure that blood irons level stay suppressed.

Objective: Attempting in vivo healing of cyclophosphamide-induced ovarian insufficiency in a mouse model using bone marrow mesenchymal stem cells (BMMSCs). Methods: Female BALB/c white mice were used to prepare a model for premature ovarian failure by single intraperitoneal injection of cyclophosphamide (80 mg/kg). Ten mice were injected with BMMSCs and then sacrificed after 21 days for morphometric evaluation of the ovaries. Hormonal profile was evaluated while mice were being sacrificed. Another 10 mice were left for natural breeding with male mice, and 5 of these were injected with BMMSCs. Oocyte-like structures were obtained from 3 mice and were subjected to in vitro fertilization/intracytoplasmic sperm injection. Results: Morphometric analysis of the ovaries demonstrated the presence of newly formed primordial follicles. Contribution of MSCs to the formation of these follicles was proven by a labeling technique. There was a drop in estradiol and rise in follicle-stimulating hormone levels, followed by resumption of the hormonal levels to near normal 21 days after MSCs therapy. The 5 mice that were injected with MSCs became pregnant after natural breeding. Fertilization and further division was reported in 5 oocytes subjected to intracytoplasmic sperm injection, but division did not continue. Conclusion: From this proof-of-concept trial, we can say that healing of damaged ovaries after chemotherapy in mice is possible using in vivo therapy with BMMSCs. This should open the gate for a series of animal studies that test the possibility of in vitro maturation of germinal epithelium of the ovary into mature oocytes.

Bone marrow mesenchymal stem cell repair of cyclophosphamide-induced ovarian insufficiency in a mouse model - Dove Medical Press

Newswise You might think stem cells only exist inside a fetus, but your adult body has a stockpile of stem cells, armed and ready to respond. These remarkable cells can develop into any other type of cell, like muscle or bone or nerve cells.

Researchers know heart attacks and strokes summon these cells. They flock to your heart or brain from all over your body to help you stay alive.

But, scientists did not realize other injuries, like a torn ACL of the knee, could command the army of stem cells to deploy.

Kevin Baker, Ph.D., Beaumont director of Orthopedic Research, conducted a study with Beaumont orthopedic surgeon Kyle Anderson, M.D., and others that revealed ACL tears send a signal to stem cells throughout our body.

After an ACL tear, Dr. Baker and his colleagues found a six-fold increase in stem cells circulating around the knee, similar to the bodys response to a major, life-threatening event like a stroke or heart attack.

However, when the stem cells arrive to help regenerate and repair the injured ligament, they get stuck. They cant get through the thick membrane that surrounds the knee joint.

We think this discovery will help us to understand how the body responds to an ACL injury, and also how post-traumatic osteoarthritis develops after a joint injury, Dr. Anderson said.

Post-traumatic osteoarthritis is a form of arthritis that develops after a knee injury. Its a common injury that affects veterans, athletes and anyone who puts stress and strain on their knees. But, until now, little was known about how the body attempts to heal these injuries.

As we age, the number of stem cells in our body declines. This could explain why your knee joint doesnt heal as well after a trauma when you are older, Dr. Baker said.

Osteoarthritis affects more than 30 million adults in the United States, according to the Centers for Disease Control and Prevention, and many of these cases occur after trauma to a joint. Its also a leading cause of disability.

The next step of our research will be finding methods to get the stem cells inside the joint. If the stem cells can get through the membrane around the knee, they could help speed up the healing process and perhaps delay or prevent arthritis, Dr. Baker added.

The study, funded in part by the American Orthopedic Society of Sports Medicine, is entitled, Acute mobilization and migration of bone marrow-derived stem cells following anterior cruciate ligament rupture. The authors believe it is the first study of its kind to reveal the bodys systemic stem cell response to an ACL injury.

Dr. Baker and Dr. Andersons research will appear in an upcoming edition of the journal Osteoarthritis and Cartilage. Other members of the research team are Perry Altman, M.D., Beaumont orthopaedic surgery resident, as well as Asheesh Bedi, M.D., and Tristan Maerz, Ph.D., of the University of Michigan.

Researchers Discover Body's Stem Cell Army Hits a Wall When ... - Newswise (press release)

AUSTIN, Texas -- Gov. Greg Abbott has signed a new law that allows terminally ill or those which chronic diseases receive stem cell treatments in Texas.

Stem cell therapy is the use of stem cells to treat or prevent a disease or condition, and is often patient's last hope for improvement.

Bone marrow transplant is the most widely used stem-cell therapy, and can often help those with multiple sclerosis and other diseases.

House Bill 810, which was introduced by Rep. Tan Parker, R-Flower Mound, passed in both the Texas House and Senate.

"It is easy to fall into the trap of viewing legislation as just words on a piece of paper," said Sen. Paul Bettencourt, R-Houston, the bill's sponsor in the Senate. "But for the many people who are ill with multiple sclerosis and other diseases that stem cell therapy has the hope of solving in our lifetime, I look at this bill, I look at the possibility of what can happen in the 21st Century, with Texas taking the lead on adult stem cell treatments and this bill has the potential to extend lives and make a difference for these patients."

The Texas Medical Board will be responsible for writing the rules for the treatment.

"Everyone has a zest for life. This adult stem cell treatment possibility gets government out of the way to let these new therapies flourish and give these patients hope for a future good quality of life," Bettencourt added.

The legislation takes effect Sept. 1.

-- Value of Stem Cell Therapy --

According to the National Institues of Health, stem cellshave the remarkable potential to develop into many different cell types in the body during early life and growth.

In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive.

When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Doctors say stem cells are important for living organisms for many reasons.

In the 3- to 5-day-old embryo, called ablastocyst, the inner cells give rise to the entire body of the organism, including all of the many specialized cell types and organs such as the heart, lungs, skin, sperm, eggs and other tissues.

In some adult tissues, such as bone marrow, muscle, and brain, discrete populations of adult stem cells generate replacements for cells that are lost through normal wear and tear, injury, or disease.

Governor Signs Law to Allow Chronic, Terminally Ill in Texas to Get Stem Cell Treatments - Spectrum News

Bone Marrow Stem Cells Comments Off on Governor Signs Law to Allow Chronic, Terminally Ill in Texas to Get Stem Cell Treatments – Spectrum News | June 14th, 2017

Dr. Keith Roach, Syndicated Columnist

DEAR DR. ROACH: I hope you can answer some questions about myelodysplastic syndrome. What does it do to your body? Is there a known cause or cure? What is the prognosis? P.B. ANSWER: The myelodysplastic syndromes are a group of similar diseases, specific types of blood cancers, that prevent your bone marrow from working properly. They also can transform into acute leukemia. These are uncommon cancers, with perhaps 30,000 cases per year in the U.S. The specific myelodysplastic syndromes are now categorized by appearance, genetic abnormalities of the cells, and condition of the bone marrow.

MDS may arise from damage to DNA, such as from radiation or other toxic exposures. However, many cases have no known cause, and its likely that these are spontaneous mutations in the bone marrow cells.

Because MDS is a group of related diseases, the treatment and prognosis vary among the different subtypes. However, supporting the bone marrow with transfusions of red blood cells and platelets often is necessary. Medications to stimulate both red and white blood cell production can be used. A few people will be recommended for bone marrow (stem cell) transplant, but the decision to consider this treatment must be made cautiously, as many people who get MDS will not benefit from this treatment due to age or other medical conditions.

The prognosis depends on the age of the person affected and their specific MDS. A person younger than 60 with a low-risk MDS has a median survival (based on data published in 1997) of about 12 years. However, high-risk MDS has a much worse outcome: Half of people succumb within six months. Advances in treatment since these data were published have improved these results, but not as much as hoped.

DEAR DR. ROACH: My 89-year-old mother suffers from fluttering in her heart. She saw an expert in cardiac arrhythmias, who diagnosed her with tachy-brady syndrome and sick sinus syndrome. A nurse also said she has PVCs. She is taking metoprolol, but still has episodes of fluttering. What are these conditions? Are there other medications she could take to correct this heart condition? M.D.P.

ANSWER: Tachy-brady syndrome (from the Greek roots for fast and slow) and sick sinus syndrome are the same thing. The sinus in sick sinus syndrome refers to the sino-atrial node of the heart, which is the hearts natural pacemaker. It is where every beat normally starts. This part of the heart can become diseased, and the heart can beat both too quickly (tachycardia) and, at other times, too slowly (bradycardia). Sick sinus syndrome can come from many different conditions and, rarely, from medications.

Medications are sometimes used for sick sinus syndrome. Beta blockers, like the metoprolol your mother is taking, are given to slow down the tachycardic component of sick sinus, but it can make the bradycardia worse. Most often, the treatment for sick sinus syndrome is a permanent pacemaker. Not everyone needs it, but Im sure your mothers cardiologist is monitoring her and will recommend a pacemaker if needed. If one is necessary, 89 years old is not too old to put in a pacemaker.

PVCs are very common and do not usually indicate disease in the heart, although they are more common in people with heart disease, especially poor blood flow to the heart. Premature ventricular contractions themselves seldom need treatment.

Release from the University of Virginia Health System:

CHARLOTTESVILLE, Va., June 14, 2017 - University of Virginia Cancer Center has earned recognition as a national center of excellence for its care of patients with myelodysplastic syndrome (MDS), a cancer of the bone marrow that often leads to leukemia.

UVA is the only center in Virginia to receive this designation from the MDS Foundation for the treatment of this condition, which UVA hematologist Michael Keng, MD, said is often referred to as a bone marrow failure disorder.

Bone marrow produces stem cells that make white blood cells, red blood cells and platelets. In patients with MDS, the marrow does not produce enough healthy cells. When there are not enough healthy cells, there is an increased risk of infection, bleeding, easy bruising and anemia. Approximately 30 percent of patients diagnosed with MDS will progress to a diagnosis of acute myeloid leukemia.

According to the MDS Foundation website, centers of excellence have:

UVA provides tailored care for each MDS patient through a multidisciplinary team. UVAs care team includes medical oncologists/hematologists, pharmacists, care coordinators, nurses, infectious diseases specialists, clinical trial coordinators, and support services such as social workers, case workers, and therapists.

UVA is devoted to providing support, research, treatment and education around MDS to all patients, caregivers, physicians, nurses and other healthcare providers, Keng said.

Fat doesn't just sit on top of your bones according to recent research it can also be found inside of your bone marrow too, and running can help shrink it.

According to Dr. Maya Styner, the study's lead researcher and an assistant professor of endocrinology and metabolism at the University of North Carolina at Chapel Hill, exercise has the ability to improve bone quality, particularly in obese mice.

Though the research on mice is not directly translated to human results, Styner says, "The kinds of stem cells that produce bone and fat in mice are the same kind that produce bone and fat in humans."

Marrow is the spongy tissue found inside some of your bones and is comprised of stem cells, nerves, blood vessels and fat. In healthy adults, bone marrow is half red and half yellow.

The yellow portion of bone marrow is used to store fats and provide sustenance required for bone function. In the event of severe blood loss or fever, yellow marrow can turn red.

Styner's study suggests that, like other types of body fat, marrow fat can be used as a source of energy.

"There's been intense interest in marrow fat because it's highly associated with states of low bone density, but scientists still haven't understood its physiologic purpose," said Styner. "We know that exercise has a profound effect on fat elsewhere in the body, and we wanted to use exercise as a tool to understand the fat in the marrow."

The study, which looked at the marrow fat in mice, found after six weeks obese mice who ran on a wheel had a significant reduction in the size of their fat cells, and in some cases appeared identical to lean mice.

"One of the main clinical implications of this research is that exercise is not just good, but amazing for bone health," said Styner. "With obesity, it seems that you get even more bone formation from exercise. Our studies of bone biomechanics show that the quality and the strength of the bone is significantly increased with exercise and even more so in the obese exercisers."

Legacy of Houston's first 'Bubble Boy' helping children born decades later

Though he only lived for 12 years, the life of Houston's David Vetter captivated the public as he grew up isolated from germs and human touch due to a rare, inherited condition calledSevere Combined Immunodeficiency Disorder, or SCID.

This weekend HoustonChronicle.com told the story of a Houston child named Sebastian Romero who suffers from the same condition.

Vetter lacked the white blood cells that fight infection, meaning any germ was a potential killer. When he was born in 1971, there was no treatment. The "Star Wars"-loving kid died in February 1984after doctors attempted an experimental bone marrow transplant.

Story continues below...

A TV movie starring John Travolta partially based on Vetter's story was released in 1976, but it took many liberties with his situation. Hollywood has also attempted to turn bubble boy cases into comedy with 2001's "Bubble Boy" starring Jake Gyllenhaal and a 1992 episode of Seinfeld.

Born in February, the cute, chubby-faced Romero has decades of medical research on his side that Vetter did not. But Romero isn't completely out of the woods, as reporter Mike Hixenbaugh writes on HoustonChronicle.com. His family has a hard road ahead of them. SCID is still a very scary condition in any decade, but the doctors at Texas Children's Hospital are calling on lessons from 33 years ago to help save the boy's life.

Over the past few years, Texas Children's has treated several SCID babies, and most had been cured through bone marrow or stem cell transplants.

After a nationwide search, no matching donor could be found for Sebastian. Texas Children's instead proposed giving a stem cell transplant from a half-matching family member, the same treatment that failed to cure David more than 30 years ago.

If Sebastian is going to survive, it will be his mother's stem cells and lessons from the Bubble Boy that will save him.

The Romero family is currently holding an online fundraiser to help them pay for some of the expenses related to Sebastian's ongoing care.

When President Donald Trump urged the biopharmaceutical industry to reduce the price of new medicines and to increase its manufacturing in the United States, many took it as a threat.

We believe its a call to action. Americas ingenuity in biomedical research is unsurpassed. However, our country is losing out to other nations in the fastest growing biotechnology sector, called regenerative medicine: harnessing the capacity of our cells to repair and restore health and sustain well-being.

Second place is not an option. The regenerative medicine market is growing about 21 percent a year and is expected to be worth over $350 billion by 2050. Today, the U.S. regenerative medicine sector is generating $3.6 billion in revenues and has produced 14,000 jobs. By 2050, the industry could create nearly a million new jobs nationwide.

Regenerative medicine will also reduce the cost of disease. Such therapies will replace drugs, devices, and surgery, saving lives, increasing productivity, and reducing the cost of care. This transformation will add trillions in value to our economy.

Finally, regenerative medicine will also make America more secure. Our nation still lacks the ability to quickly and cheaply mass produce vaccines, antidotes, and cell therapies to counter pandemics and bioterrorism. Our fighting forces need reliable sources of these countermeasures and deserve immediate access to treatments that give them back their lives. We shouldnt outsource the safety and well-being of our nation and our Armed Forces to other countries.

To regain leadership in regenerative medicine, U.S. firms dont need government loans, tax credits or massive de-regulation. Instead, it needs the opportunity to invest in reducing the time and cost of manufacturing cellular therapies. To the extent that regenerative medicine is curative it must be made available at vaccine like prices. At present, only a handful of people can afford such treatments.

China and Japan are now in forefront of reducing the cost of producing stem cells, tissue, and other products with restorative biological properties. As a result, they are attracting more capital and forming more new companies than the U.S.

In 2014 Japan became the first country in the world to adopt an expedited approval system specifically for regenerative medical products and to allow outsourced cell culturing. Two products were approved under the new system within a year of its adoption.

By contrast, the Food and Drug Administration regulates any use of manufactured stem cells as equally risky without regard to prior use, health benefit, or therapeutic potential. Indeed, many of the most common stem cell therapies including bone marrow transplants and blood transfusions would require 10 years of FDA review if they were brought to market today.

The problem isnt over-regulation. Its outdated regulation. Safety checks and benchmarks for cell manufacturing should be based on real world evidence of past applications. Regulation should focus on the specific potential side effects for each specific potential use. In this regard, we agree with incoming FDA Commissioner Scott Gottlieb, who has noted, Expediting the development of these novel and transformative technologies like gene- and cell-based therapies doesnt necessarily mean lowering the standard for approval, as I believe other countries have done. But it does mean having a framework thats crafted to deal with the unique hypothetical risks that these products pose.

In fact, the United States has the best regenerative medicine manufacturing technology in the world. But it is literally sitting unused in warehouses.

For example, under the Accelerated Manufacture of Pharmaceuticals program, private companies partnered with the Defense Advanced Research Projects Agency to develop mobile cell and tissue manufacturing plants that can be set up almost anywhere. The facilities can produce cells and tissues at a fraction of the current cost. These mobile factories make real-time production of vaccines and biologics for potential bioterrorist threats and pandemics possible. They are also low-cost, high-tech platforms for experimental evaluation of any type of regenerative medicine.

AMPs are operating in Indonesia, Singapore, China, and Japan where cell products including vaccines are being mass produced. Not a single AMP is being used in the United States because of outdated regulations.

To remove this regulatory obstacle, the Trump administration should establish a separate regenerative medicine pathway. This pathway, which could be developed by DARPA, FDA, and the Centers for Disease Control and Prevention, would develop regulatory standards for the safe manufacturing and testing of development of regenerative products to treat battlefield related traumas such as traumatic brain injury, life-threatening limb damage, and drug-resistant pathogens.

The focus on the conditions and circumstances unique to war or counter-terrorism is both appropriate and strategic. After World War II, Franklin Roosevelt directed that the scientific and entrepreneurial talents used to achieve ramp up war-time production of penicillin and blood plasma be used in the days of peace ahead for the improvement of the national health, the creation of new enterprises bringing new jobs, and the betterment of the national standard of living.

What was created exceeded that vision. The cooperative efforts to achieve mass production of penicillin and blood plasma inspired and supported the creation of industries that employ millions of people today.

Similarly,developing an affordable source of cell therapies to heal our fighting forces and protect the homeland will yield a wide array of affordable technologies and cures that will produce, in FDRs words, a fuller and more fruitful employment and a fuller and more fruitful life. Simply put, by making the manufacture of regenerative medicine affordable can help make America great.
