Lungs are a crucial organ in many animals, including humans. While their function has always seemed pretty straightforward to take in oxygen, transfer it into blood, and exhale carbon dioxide scientists have found a previously unrecognized function of the lungs of mice: blood production.

The study, which was published in Nature by researchers at the University of California San Francisco, was performed by inserting fluorescent protein into the mouses genome.

The protein caused the platelets (small blood cells that bind together to help create blood clots when a blood vessel is damaged), in the mouse to glow, allowing scientists to trace the platalets paths. What they found was a massive number of megakaryocytes, a stem cell that produces in the lungs.

When researched further, scientists found that the lung was producing over 10 million blood-producing platelets per hour, and the platelets produced by the lung accounted for the majority of platelets in the mouses circulatory system. Researchers are theorizing that the megakaryocytes are created in the bone marrow, but then travel to the lung to produce platelets.

While it is known that human lungs produce platelets and produce blood, as small amounts of megakaryocytes have been found in lungs before, if these findings are reproduced in humans, it will prove that the sheer amount that lungs produce has been greatly underestimated.

The study also found a reservoir of stem cells with the ability to become blood cells in the lungs. Researchers implanted lungs with the fluorescent megakaryocyte cells into mice that had been engineered to have no blood stem cells in their bone marrow, and found that the fluorescent cells travelled from the lungs to the marrow, and helped to produce platelets and other ingredients in blood, including neutrophils. In cases where the bone marrow is dealing with platelet or stem cell deficiency, these stem cells were able to leave the lung and contribute to the refilling of platelets in the marrow.

If further research indicates that these findings also apply to humans which they very well may, considering the genetic and biological similarities between mice and humans it will not only disprove the current theory that states the bone marrow accounts for most of the human bodys platelet production, but it will also affect how scientists approach treating blood diseases in humans, particularly ones that result in a platelet deficiency, such as thrombocytopenia.

Stem cell differentiation can now be seen thanks to a combination of machine learning and microfabrication techniques developed by scientists at the RIKEN Quantitative Biology Center in Japan. The results, published in PLOS One, followed the differentiation of human mesenchymal stem cells (MSC) which are easily obtained from adult bone marrow.

MSCs have proven to be important for regenerative medicine and stem cell therapy because they can potentially repair many different types of organ damage, as they have the ability to differentiate into various cell types including bone, muscle and fat. Depending on the way the cells are grown the results can be quite different and so controlling differentiation is an important goal.

Observing MSC differentiation under different conditions is an essential step in understanding how to control the process. However, this has proved challenging on two fronts. First, the physical space in which the cells are grown has a dramatic impact on the results, causing significant variation in the types of cells into which they differentiate. Studying this effect requires consistent and long lasting spatial confinement. Second, classifying the cell types which have developed through manual observation is time consuming.

Previous studies have confined cell growth with fibronectin on a glass slide. The cells can only adhere and differentiate where the fibronectin is present and are thus chemically confined. However, this procedure requires high technical skill to maintain the confinement for an extended period of time. To overcome this, the first author of the study, Nobuyuki Tanaka, decided to look for a new way to confine them. Using a simple agarose gel physical confinement system, he found that he could maintain them for up to 15 days. Tanaka says, "It was wonderful to be able to do this, because agarose gel is a commonly used material in biology laboratories and can be easily formed into a micro-cast in a PDMS silicone mold."

He continues, "The advantage of this system is that once the PDMS molds are obtained the user only needs agarose gel and a vacuum desiccator to create highly reproducible micro-casts." The vacuum pump pulls the agarose gel into the mold. He explains, "We provided the protocol to our coauthors at ETH Zurich and they performed the agarose micro-casting and conducted the stem cell differentiation study. Stem cells were captured in the micro-structures and their differentiation was controlled under the captured condition."

Tanaka's paper also describes an automated cell type classification system, using machine learning, which reduces the time and labor needed to analyze cells. "Combined together, these tools give us a powerful way to understand how stem cells differentiate in given conditions."

According to Yo Tanaka, leader of the Laboratory for Integrated Biodevice, where the research was conducted, "We hope this will break down the barriers that have hindered research in this area so far and help to establish harmony between biologists and engineers. The focus of engineers has traditionally been to develop new technologies, but scientists prefer to use well established technologies. However, if our newly developed technology is simple enough it can spread rapidly, this is our goal."

New technique helps researchers determine how stem cells differentiate - Phys.Org

A small, but promising study suggests that stem cells from a childs own cord blood may offer an effective treatment for autism symptoms.

Most children on the spectrum who received an infusion from their own umbilical cord blood showed improvements in behavior, communication and socialization, among other measures, while experiencing no significant downsides from the treatment.

The findings come from a study of 25 kids with autism ages 2 to 5 published Wednesday in the journal Stem Cells Translational Medicine.

All of the children who participated in the research had their cord blood banked at birth. For the trial, the kids were given a series of behavioral and functional assessments before receiving a one-time cord blood infusion. Follow-up assessments were conducted at six and 12 months after the infusion.

Not only did the researchers find that the treatment was safe, but parent reports as well as clinical assessments indicated that more than two-thirds of the children saw improvements in autism symptoms.

Most of the behavioral gains were seen in the first six months after the infusion, the study found, but they were sustained over the following six months.

We are pleased that this study demonstrated the safety of treating children with ASD with their own cord blood, said Joanne Kurtzberg, a pediatric bone marrow transplant specialist at Duke Health who worked on the study. Were also encouraged that, while small and non-randomized, there were observed improvements in a majority of the children reported by clinicians and parents.

While the findings are encouraging, researchers said that further study involving more participants is needed before any firm conclusions can be reached about the effectiveness of cord blood infusions.

We are now hoping to replicate these preliminary results in a Phase II randomized clinical trial for which enrollment is nearly complete, Kurtzberg said.

Stem Cells Show Promise For Treating Autism - Disability Scoop

For about half a decade, its been something of an open secret in baseball that playerspitchers especiallyregularly undergo stem-cell therapy to stave off surgeries and lost playing time. Its a cutting-edge medical procedure, done by everyone from high-school standouts to major-league all-stars. Its rarely discussed by players, or by their coaches, parents, doctors, or employers.

So when the Los Angeles Angels went public in 2016 with the news that first Andrew Heaney and then Garrett Richards were undergoing stem-cell therapy for torn ulnar collateral ligaments (UCLs), it was both anticlimactic and a revelation. For the first time, baseball pitchers and their employers were openly admitting trying this novel procedure that, while fairly well-proven anecdotally, has yet to be validated by any well-designed scientific study.

By now, that so-called Tommy John surgery for a torn or damaged UCL has become a rite of passage for the top-flight professional baseball pitcher is a cliche of sports punditry. Every young arm that can fold and then unfold itself into tortuous patterns that facilitate throwing baseballs at 95 miles per hour or faster is bound for the knife, once those upper body contortions inevitably tears the tissue on the inside of their elbows connecting their upper and lower arms, the UCL.

The first Tommy John surgery (or more properly, UCL reconstruction) was performed in 1974 by the orthopedic surgeon Frank Jobe, then the team physician for the Los Angeles Dodgers, on the eponymous pitcher. It was a great success; Tommy John came back to pitch 14 more years in the pros, racking up 164 wins with four different teams.

TJ surgery is fairly straightforward: the connective tissue that makes up the UCL is either replaced with a tendon taken from elsewhere in the patients own body or from the donated tissue of a cadaver.

Nevertheless through the mid-1970s and into the 80s, TJ was something of a rarity; just a handful of baseball players underwent that particular knife. In the 1990s the numbers started to tick up, and then in the 2000s, they exploded. From 1995 to 2005, there was an average of 28 TJ surgeries per year across all levels of pro baseball; from 2005 to 2015, there was an average of 84 TJ surgeries per year.

Then something strange happened. In 2016, the total number of TJ surgeries performed dropped to 90, from 127 the year before, a 30% decline. Only one other year in Tommy John history, 2008, saw such a precipitous drop from the previous year. By 2009, TJ numbers were back to 2007 levels; obviously it remains to be seen whether 2017 will look more like 2015 or more like last year. But the data suggest that if TJ surgery numbers are in fact starting to trend downward, it might have something to do with the rise of stem-cell therapy.

What makes stem cells unique is that they are whats called undifferentiated; they can become other specialized cells depending on the bodys need at the time. There are two types of human stem cells, embryonic and adult. Embryonic stem cells come from a very early-stage embryo; these are what you likely think of when you hear the term stem cellstheyre at the center of one of most exciting fields of medical science research today. Embryonic stem cells are now used or are being studied for a shockingly wide range of applications, from Alzheimers and autism to vision impairment and infertility. However, thanks to the religious right-driven opposition to the harvesting, study, and use of embryonic stem cells, theyve been mired in controversy in the US.

On the other hand, the use of adult stem cellswhich can be harvested from bone marrow, fat, or blood of any person of any age (the name is a bit misleading)is widely accepted by both the medical community and politicians. They have less range, so to speak, than embryonic stem cells; they are primarily to repair and replace damaged tissue in the area they are found. That makes them just about perfect for repairing a torn UCL.

The first pro baseball player known to have undergone stem-cell therapy for a UCL weakness was Bartolo Colonand he was basically forced into talking about it. Following a long run of success culminating with a Cy Young Award season in 2005, Colon had four frustrating years racked with injury and ended up unsigned after 2009. He took a year off to recuperate and in spring of 2011, he was back, signed with the New York Yankees and feeling good. Serge Kovaleski, an investigative reporter with the New York Times, started digging into how Colon had made his comeback, and uncovered the name of Joseph Purita, an orthopedic surgeon and stem-cell therapy pioneer.

As Purita tells it, there was nothing illegal or nefarious about the work hed done on Colon; there was just never a plan to broadcast it, either. Then, he recalls, the Times called me up and said were going to write a story whether or not. So, Purita offered details. In April 2010, he told the paper, a team of Dominican doctors used stem-cell therapy to help repair Colons ligament damage and torn rotator cuff.

Colons recovery was a resounding success. Hes been an all-star twice, is the current active leader in major league wins, and, at age 44, is signed to a $12.5 million contract to be the Atlanta Braves number two starter for the 2017 season.

I cant give names but there are some professionalsBut instead of thrusting stem-cell therapy into the mainstream, the Colon incident forced it to stay underground. The treatment was not well understood at that point, and the circumstancesthat it was done offshore, that it was unearthed by investigative reporting, and that, in 2012, Colon was suspended for 50 games for testing positive for testosterone useclouded public opinion on it. Many were convinced Colon had gotten performance-enhancing drugs in the Dominican Republic. Purita denies this vociferously, and MLB inquiries back him up.

The upshot is that every doctor I spoke to who studies and performs stem-cell therapy for torn-ligament repair says some version of the same thing: I cant give names but there are some professionals who have come in for treatment, says Joshua Dines, an orthopedic surgeon at New Yorks Hospital for Special Surgery, and an assistant team physician for the New York Mets.

Purita says that since Colon, hes worked with some players that had team approvaland some just come on their own, but none wanted to go public about the procedure.

If use of your arm is mostly limited to spreadsheet jockeying and lifting forkfuls of pasta or salad from plate to maw, TJ is no big dealin that case, youre ready to go back to work in six weeks. But if you throw a ball at top speed past another pro athlete for a living, youre going to be out of commission for 18 months or more as you regain strength in your money arm.

And money is the (post) operative word. In 2016 alone, MLB teams lost nearly $60 million in player value because they had to fulfill dozens of contracts of players recovering from Tommy John. Thats nearly enough to field an entire pro teamdefinitely enough to roster a top-of-league pitching staff. And that $60 million doesnt come close to accounting for the losses suffered by players who had to undergo the knife during the last year of a contract, and found themselves released by their previous teams with no new offers on the table while they recovered.

There was never going to be a way to prevent the need for Tommy John surgeries. Baseball players throw far too hard, with far more breaking pitches, starting at far too young an age, to realistically stop UCLs from tearing (though all sports medicine experts do now warn coaches and parents to keep kids and teens at low pitch counts). The alternative was always going to be something that could cure ligament tearsbut better than TJ surgery, with a faster recovery time.

Everything weve seen in the past decade or so suggests stem-cell therapy is exactly that. At this point, platelet-rich plasma (PRP) injections are common first-line defenses against UCL injuries. The procedure entails harvesting PRP from the player and injecting it into the injured part of the body. PRP is dense with proteins specialized for injury repair.

You can think of these injections as a precursor to stem-cell therapy; both are considered biologic treatments and entail wielding the bodys own weapons against injury. Many of the doctors now doing stem-cell therapy started off with PRP procedures. When baseball players have a torn ligament, they typically try PRP first. If that fails, its Tommy John time.

Everyone in the field says that at this point PRP is last decades technologyExcept, everyone in the field says that at this point PRP is last decades technology, more than ready to be replaced by stem-cell therapy, which does much the same thing but better. Adult stem cells essentially are there for the very purpose of tissue repair. Why not take them from a part of the body thats all good, and send them to a region where reinforcements are desperately needed?

Dines says that in his own practice, hes been able to cut down the need for Tommy John surgery by about a third, thanks to his reliance on stem-cell therapy. He doesnt believe that the procedure will lower the number of players that have to have TJ, but it will limit the number of overall TJ surgeriesbecause at this point, many pitchers have to get the surgery twice in their career. Dines says stem-cell therapy can get 15- or 16-year-old pitchers through their first partial tear. They may still need to get a full TJ surgery by age 24, but avoiding that first one is still a huge victory. (A growing number of middle-age first-time TJ patients could also explain the overall drop in Tommy John surgeries.)

Purita is even more optimistic. While most orthopedic surgeons say that, right now, stem-cell therapy is effective on partial, but not full, ligament tears, Purita is confident his version can handle any UCL. He sent Quartz a photo showing a patientan MLB pitcher who wishes to remain anonymous, Purita sayswho had a full UCL tear in November 2011 and, after receiving stem-cell therapy at Puritas clinic, made a full recovery by February 2013.

You never say something replaces something else entirely, Purita says. Stem-cell therapy is not going to replace every case [of Tommy John], but it could probably replace the majority of cases.

Talk to anyone who knows the field and theyll rattle off the same reasons why stem-cell therapy for UCL tears isnt already the standard of care: One reason is that, relative to the population, the number of UCL tear patients is extremely small, which means theres only a tiny pool from which to draw potential study participants. Two, a trial for a new medical treatment is typically only considered well-designed if the subjects are blindthat is, they dont know if they are getting the real treatment or a placebo. But what kind of team or player is going to risk a million-dollar arm on a properly designed study where theres a 50% chance that the injury gets a placebo?

Thats not to say that this is some sort of back-alley procedure. Its performed by some of the most prestigious orthopedic surgeons and medical research centers in the US, and the US Food and Drug Administration approves its use: US doctors are allowed to harvest a persons stem cells and use those cells to treat that same person, as long as you dont manipulate (e.g. genetically modify) the cells.

Someone making $20 million a year is not going to do something he hasnt checked out wellThe lack of literature on the procedure hasnt exactly inspired the confidence of players and teams to go public with their decision to pursue it; nor does the fact that the procedure for years had, as Dines puts it, a bad rap[it] would get lumped in with things that were illegal. There was this specter of cheating. But Dines, and others, say thats changing.

The needle is moving towards this being a valid way of treating things, says Purita. People are starting to recognize that someone making [or risking] $20 million a year is not going to do something he hasnt checked out well.

Amadeus Mason, a sports medicine and biologics expert at Emory University, compares stem-cell therapy today to Tommy John in the 1980s. It was, Okay, were going to try this and see, says Mason, who trained with orthopedic surgeon James Andrews. (Andrews is the Michael Jordan of ligament repairhes saved the arms and careers of some of the greatest pitchers in major league baseball history.) There wasnt a big fanfare going in when players started with Tommy John surgeries, Mason says, but when players came back to pitch [there] was. Same thing here.

Mason thinks stem-cell therapy hasnt quite reached the inflection point, but it is near. Here, too, he sees a comparison with Tommy John: It took a while for them to perfect the procedure so that more and more doctors could do the surgery and reproduce the results well.

Right now, Mason says, there is a relatively small handful of doctors who can do stem-cell therapy for UCL tears, but that list is growing rapidly. For example, the annual conference of the Orthobiologic Institutea professional organization for regenerative medicine researchers and practitionersstarted in 2009 with 20 or so doctors; last years event had nearly 1,000.

Some players can throw faster after they have the surgeryThe Angels didnt want to talk to me about why they decided to go public with Heaney and Richards stem-cell therapies. Perhaps thats because Heaneys, on May 2, 2016, was unsuccessful. The 25-year-old former first-round draft pick underwent Tommy John surgery in July of that year after failing to regain strength in his left arm. Hell miss the entire 2017 season, setting back a promising young career.

Richards had his stem-cell procedure just 14 days after Heaney. So far, it seems to have worked. He didnt return to pitch in 2016, but in spring training this year, he was throwing nearly 100 miles per hour. Probably the Angels best starting pitcher, Richards will take the mound on April 5, and all eyes will be on his right throwing armand on his face, to see if it is registering any pain.

If Richards stays healthy this yearand next year, and the year after thathe could become something like the 21st-century Tommy John. Every team will have a stem-cell therapy expert on its medical staff, or at least one on speed dial. Careers will be saved, and so will millions of dollars.

But wider use of stem-cell therapy also will force the MLB to confront an interesting potential side effect of the procedure. Some players can throw faster after they have the surgery, says Purita. By definition, its making the performance better. Right now, major league baseball does not include stem-cell therapy in its list of banned performance enhancers (pdf). But what happens when a baseball player, perhaps a fringe pitching prospect in the low minors, feels some elbow pain one day and gets an MRI, and is diagnosed with nothingbut decides to get stem-cell therapy anyway, since it could give him an extra four miles per hour on his fastball?

The MLB will have a decision to make: To accept potential competitive imbalances to save young arms, or to seek to preserve a level playing field (or even just the fiction of one) at the cost of some of the games best players. The question is all but inevitable.

Stem-cell therapy is poised to disrupt the Tommy John epidemic in baseball - Quartz

Around 6,000 hematopoietic stem cell transplantations are carried out annually in Iran using the patients own cells, and a far higher number are performed using cells from donors who are often close relatives of the patient, according to the Hematology-Oncology Research Center and Stem Cell Transplantation (HORCSCT) affiliated to the Tehran University of Medical Sciences. Ardeshir Qavamzadeh, head of the center, said the number of stem cell transplants is on par with developed countries. The success rate in the treatment of diseases requiring transplant is 67% at HORCSCT, ISNA quoted him as saying. Referring to the fast and progressive development of stem cell discipline in Iran, he said since 1983, when the adult leukemia specialty was initiated in the country, nearly 300 specialists have been trained in the field and there is at least one specialist in each province now. Today, one cannot find a treatment method of stem cell transplant in the worlds advanced research centers that is not available or practiced in Iran. We have reached a level where we can compete with the developed nations. HSCT Hubs There are 10 hubs for hematopoietic stem cell transplant (HSCT) in the country. Each includes medical universities from the provinces with one as the focal point. Medical universities of Zanjan, Qazvin, Alborz and Qom comprise one of the hubs with Zanjan as the center, said Mehdi Eskandari, education deputy at Zanjan University of Medical Sciences. HSCT is the transplantation of multi-potent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. It may be autologous (when the patients own stem cells are used) or allogeneic (stem cells from a donor). It is a medical procedure in the field of hematology, most often performed for patients with certain cancers of the blood or bone marrow, such as multiple myeloma or leukemia. Since HSCT is a relatively risky procedure with many possible complications, it is reserved for patients with life-threatening diseases. However, as the survival rate following the procedure has increased, its use has expanded beyond cancer, including in autoimmune diseases, blood diseases like thalassaemia major, metabolic disorders, alcoholic liver, and even rheumatism.

Three Bangladeshis suffering from a highly debilitating muscular dystrophy, who arrived in Mumbai on Sunday have begun their treatment at a Navi Mumbai spine clinic.

Abdus, Rahinul and Shorab aged 24, 14 and 8 respectively were diagnosed with this crippling disease at the time of their birth.

They arrived on Sunday evening and we started the treatment on Monday, said Avantika Patil, spokesperson NeuroGen Brain and Spine Institute in Seawoods, Navi Mumbai, who is treating them for free.

They are undergoing an autologous bone marrow derived stem cell treatment. Stem cells are taken from the bone marrow in their hip bone, treated in our lab and then injected into to the patients again. We will provide a combination of stem cell therapy and neuro-rehabilitation which will also includes yoga and speech therapy sessions, Patil explained.

While the hospital is not willing to say what kind of progress can be expected in these particular cases, they revealed that in one case, a bed-ridden patient was able to walk slowly after six years of treatment.

In January, fruit seller Tofazzal Hossain sparked a rare debate about euthanasia in conservative Bangladesh in January when he pleaded with the authorities to allow his grandson and two sons to die.

Stem cell treatment begins for dystrophy patients from Bangladesh - Daily News & Analysis

Mumbai, Apr 4 (PTI) Three Bangladeshi patients, suffering from an incurable muscular dystrophy, today underwent first stem cell therapy at a Navi Mumbai based treatment centre.

"We applied a simple therapy to the patients. We took out the stem cells from their bone marrow in the hip bone and after the required processing we injected it back into their body.

"We will wait for the results as to how they respond to such treatment. Meanwhile, physiotherapy and occupational therapy is being offered to them as well," Avantika Patil, coordinator between the patients and the treating centre told PTI.

Patil, is part of the team of NeuroGen, a brain and spine institute that keeps the track of its patients.

"We learnt about the patients through an article in an international newspaper and decided to contact them as we specialise in treating such diseases.

"I am also in contact with one Noor Khan from Bangladesh, an activist who helped the three patients to furnish documents and visa procedures," she said.

A Mumbai-based organisation specialising in such diseases, Meditourz, in collaboration with NeuroGen based in Navi Mumbai, offered to provide treatment to them.

The trio have been suffering from a rare disease Duchenne Muscular Dystrophy since their birth. This is a genetic disorder which causes progressive muscle degeneration and patients rarely live beyond 30 years of age, Patil said.

Among the three, Shorab (8 year old) is having a mild disorder and early medical intervention will definitely help in terms of less painful life. Compared to him, the disease is progressive in other two patients, she said.

Tofazzal Hossain, a fruit vendor from rural Meherpur in Bangladesh, had sought mercy killing for his sons - Abdus (24) and Rahinul (14) - and grandson Shorab from his government as he could not afford the cost of their treatment.

The Navi Mumbai based centre approached the three patients through Indian government and expressed willingness to provide treatment to the disease.

Air India also offered free round trip tickets to the six persons -- three patients and three caretakers accompanying them to Mumbai from Kolkata following an appeal from Alok Sharma, neurosurgeon at the NeuroGen.

"The three patients and the three persons accompanying them took this evenings Air India flight from Kolkata to Mumbai and will also return by an Air India flight after treatment - entirely free of any charges," Air India said in a statement. PTI ND RMT

LORENA, Texas (KWTX) Lorena residents and others from around Central Texas turned out Monday to register as bone marrow donors in support of a first grade teacher with a rare medical condition, the only cure for which is a bone marrow transplant.

Melinda Colyer, who teaches at Lorena Primary School, was diagnosed with myelodysplastic syndrome with myelofibrosis about two weeks ago.

"It's actually a disease that causes the destruction of your stem cells in your bone marrow. They do consider it a form of cancer. The only cure that will be provided is through a bone marrow transplant, Colyer said.

She said receiving the news was tough, but she says shes a fighter.

I decided to pick myself up and was able to go forward and that's what I'm doing at this point, said Colyer.

Lorena Primary School Principal Liza Cunningham said Colyer shines with positivity despite the diagnosis.

"Ms. Colyer is one of the most upbeat people you will ever meet in your entire life. She always has a positive attitude, she has a love for kids. It's very apparent in everything she does, said Cunningham.

The drive Monday was held at Midway High Schools Distance Learning Center.

The process takes less than five minutes, and involves a mouth swab to collect DNA samples.

Prospective donors must be in good health and between the ages of 18 to 44.

Anyone interested in becoming a bone marrow donor can sign up with Scott & Whites Marrow Donor Program.

"She wants everybody to go out and be tested because even if we are not a match for her, we would be a match for somebody else. And that's really what she's been telling us about this whole event and that's very selfless of her, Cunningham said.

This study provides the first long term evidence of the safety and feasibility of utilizing a patient's own bone marrow concentrate stem cells to treat severe low back pain

Fort Collins, Colorado (PRWEB) April 03, 2017

Retired orthopedic spine surgeon, Kenneth Pettine, M.D. is excited to release the three year results of his bone marrow stem cell treatment study. Dr. Pettine has been a pioneer in the use of bone marrow concentrate stem cell injections. He was the first surgeon to inject biologics into the human spine as part of an FDA Study in the U.S. almost seven years ago. He has the only U.S. Patent on the method of treating orthopedic and spine pathology with a patient's own stem cells.

This study provides the first long term evidence of the safety and feasibility of utilizing a patient's own bone marrow concentrate stem cells to treat severe low back pain, said Dr. Pettine. Thats terrific news for patients who up until now only had the option of undergoing expensive and invasive back fusion or artificial disc surgery.

Degenerative disc disease is a common back pain diagnosis in the United States and affects millions of patients. The symptoms of the condition can become so painful that patients may be forced to miss work and are prevented from participating in regular daily activities. Treatment is often limited to palliative care such as chiropractic, physical therapy, narcotics, injections or invasive surgical procedures to try to decrease the daily chronic low back pain. Numerous studies have shown surgery improves back pain in the average patient only 40%. Stem Cell therapy improved the average patient 70% with long term follow up.

Dr. Pettines treatment uses a patient's own bone marrow concentrate stem cells to help reduce inflammation in the spine and stimulate the creation of new tissue in the spinal disc to help reverse the effects of the disease. The office procedure is performed with I.V. sedation and usually takes 45 minutes. The study noted that patients who received higher concentrations of stem cells in their injections saw a greater improvement in their back pain.. This three year follow-up research study shows utilizing a patient's own stem cells can provide long-term back pain relief and prevented the need for invasive surgery in 77% of the patients.

If you live in the Northern Colorado area and are experiencing neck or back pain due to degenerative disc disease, you can learn more about Dr. Pettines treatment and research by visiting his website at http://www.KennethPettine.com.

About Dr. Kenneth Pettine Dr. Pettine has been the principal investigator of 18 FDA studies about stem cells and their uses and is considered a pioneer in the field. He founded The Rocky Mountain Associates in Orthopedic Medicine in 1991 to offer patients a non-fusion surgical option for their neck and back pain. He co-invented the FDA-approved Prestige cervical artificial disc and the Maverick Artificial Disc. He is currently focused on the use of Mesenchymal stem cell therapy for patients desiring to avoid orthopedic or spine surgery.

Northern Colorado Surgeon Releases Three Year Results of Bone Marrow Stem Cell Treatment - PR Web (press release)

A new method of producing red blood cells outside the body on a large scale has been developed by researchers at the University of Bristol.

'We have demonstrated a feasible way to sustainably manufacture red cells for clinical use We've grown litres of it,' saidDr Jan Frayne, one of the authors of the research which waspublished in Nature Communications.

Previously the most effective technique involved taking stem cells from bone marrow, which makes blood cells in the body,and inducing them to do the same in lab conditions. This was of limited practical success because each stem cell will only make about 50,000 blood cells before dying by comparison, a few drops of blood can contain around one billion red cells.

Working with NHS Blood and Transplant, the Bristol team overcame this limitation by engineering the stem cells to make them 'immortal', using DNA. from the human papilloma virus (HPV) which causes cervical cancer. Red blood cells cannot continue to divide in the bloodstream, and as they mature they shed their nuclei and with it the virus DNA. Thus the adult cells that might in the future be given to patients, if the technique is applied in clinical trials, would not contain the any of the HPV genetic material.

'It's a brilliant approach, and they seemed to have solved several of the really important bottlenecks,' said Dr Robert Lanza, chief scientific officer at the Astellas Institute for Regenerative Medicine, who was not involved in the project.

The lab-grown blood is likely to be much more expensive than donated blood, but there may be a number of potential applications. Lab-grown blood could be used for patients with rare blood types for whom a match is difficult to find. It could also be useful in military or disaster situations where there is no time for blood typing people who are critically injured. Interest has also been expressed by researchers of malaria and other blood-borne diseases.

The first studies to assess the safety of manufactured blood are due to begin at the end of this year, although the first trial will not test this new type of blood cell. Even if safety is established, for the time being there is not currently enough capacity to produce it and industrialising the process could be costly.

'To make big huge vats of it would be outside of our ability in a research lab,' said Dr Frayne. 'We'd have to have company interest.'

Stem cells could be used to create 'endless supply of blood' - BioNews

A benefit dinner will be held April 1 in honour of seven-month-old Madalayna Ducharme. The Warrior Princess fundraiser starts Saturday at 5 p.m. at the Parkwood Gospel Temple. All proceeds will support the family's ongoing expenses related to her medical treatment.

Madalayna suffers from malignant infantile osteoporosis, a rare genetic disorder of bone development in which the bones become thickened and unhealthy. It leads to bone fractures, short stature, poor bone growth and a thicker skull which may delay development of teeth. Left untreated, it could be fatal.

Early this year, her family started a Facebook campaign that went viral asking for people to sign up to become stem cell or bone marrow donors. Thanks to the number of people who volunteered to be tested, a match was found and Madalayna underwent a bone marrow transplant earlier this month.

The recovery is expected to be lengthy as the transplant process is grueling on an infants body. Its expected that she will need to stay in a Toronto hospital for three months while she undergoes treatment.

In Brief Studies are being done on the value of replacing older blood with younger blood via transfusions. Other researchers are studying the effects of a certain protein, osteopontin, on blood cell production. 1000 Ways To Live Forever

Society is gradually changing its classification of aging as a natural phenomenon to a disease. We have made strides in our research on preventing and potentially reversing the effects of aging.In addition to the ongoing research in molecular biology ontelomeres, there is the interesting idea of utilizing young blood to combat aging. Ironically, the legends of Dracula might be vindicated in light of new research involving young blood to rehabilitate cognitive abilities in mice, which has inspiredclinical trials that may give patients a chance at beating the Grim Reaper.

Ambrosia, a company inspired by the work done by Stanford University neuroscientistTony Wyss-Coray with parabiosis in mice, charges $8,000 per patient for its human clinical trial ofparabiosis. Although there may be 600 people whotake part in the study transfusing 1.5 liters of plasma with donors between the ages of 16 and 25, thestudy is being done without the blessing of Wyss. He believes that the study does not genuinely represent the science and that, theres just no clinical evidence, and youre basically abusing peoples trust and the public excitement around this.

While Ambrosia is operatingwithout clinical evidence to support the trials, the science behind utilizing young blood in repairing and restoring aged cellular processes is worth taking a look at.

Red and white blood cells are produced from stem cellswithin bone marrow, and as we grow older, our bodys ability to replenish the number of red and white blood cells greatly depletes. Similar to the mouse trials ran by Wyss-Coray, researcherHartmut Geigerand his team at the University of Ulm in Germany looked at the bone marrow in mice at varying ages and determined that older rodents produce very low levels of the protein osteopontin.

Rather than looking at blood transfusions for apossible solution like Wyss-Corays team, Geigers team looked the potential of stem cells to test the importance of the deficient protein.The team introduced fresh stem cells into mice that had little to no osteopontin and noticed that the stem cells aged very quickly. When older stem cells were introduced to a dish with osteopontin and anactivator protein, the stem cells began to propagate blood cells.

While companies like Ambrosia are testing blood transfusions on humans to mimic an experiment that utilized a shared circulatory system between an older mouse and a younger mouse, Geigers team notes that long-term studies must be done on their work to verify the effect of osteopontin on rejuvenating cells completely.

The team is developing a drug with the protein and its activating factor, but they do not promise a fountain of youth. They do believe that there would be benefits for the immune systems of the elderly, which may be better positioned to fight diseases that are linked with cardiovascular agingafter takingthe drug.

While all this talk about immortality is exciting, it might be a while before we can actually reap the benefits of researchers studiesin the way we hope. In the meantime, we can keep dreaming away death.

"Dancing With the Stars" pro Maksim Chmerkovskiy has been posting pictures on social media while getting treatment for his calf injury and now he's speaking out for the first time.

In exclusive video obtained by "Good Morning America," the past Mirror Ball champ is talking via video to his "DWTS" partner Heather Morris and telling her that he does not intend to lose this season.

Chmerkovskiy sat out Monday's show and Morris was paired up with pro stand-in Alan Bersten.

"I still feel like we have a chance," he tells Morris and Bersten in the video. "You deserve it and I want to give you 150 percent effort and be physically active as I was at my best."

"I want to come back and win," he says.

Chmerkovskiy has been posting several selfies from the hospital, with one captioned, "Gettin' un-broken."

Chmerkovskiy's fiancee Peta Murgatroyd previously told "Access Hollywood" that he is getting surgery for what could be tears in his calf muscle.

"It's gonna take a couple of weeks at least to get better," she said. "He's having a surgery done," but she added that he's a fighter and will be back as soon as he can.

"GMA" anchor Lara Spencer said today that doctors made a concentrate from Chmerkovskiy's bone marrow stem cells and injected them into his calf to speed up the recovery process.

Earlier in the week, the dancer thanked his fans for all their "love and support!"

"Please rest assured that I'm taking this thing very seriously and, although I don't have a concrete return date, I'll give it my all!" he said on Wednesday.

"Dancing With the Stars" returns Monday night on ABC.

Alexes Harris tells KUOW's Katherine Banwell her story.

When ProfessorAlexes Harris learned she had a rare form of leukemia, she knew she was in a fight for her life. But she didn't realize how difficult it would be to find a bone marrow match as a woman of color. This is her story.

I have a rare blood cancer called myelodysplastic syndrome.

I was diagnosed in May 2016 after a year of various tests.Prior to being diagnosed, my only health complaints were a random onset of what felt like asthma attacks during my cycling classes (the only reason I went to the doctor), feeling very tired, and not always thinking clearly. I was told that if I did not begin treatment right away I would have two years to live.

Im a 41-year-old mother of a 9 year old and 5 year old (and wife to an amazing husband), so my only true option was to begin treatment.

After being presented with treatment options, we opted for an intensive round of in-patient chemotherapy, which I underwent in June 2016 and managed symptoms in July, 2016.During my initial diagnosis I learned that I would eventually need a bone marrow or stem cell transplant. This would be my only hope of a cure.

We immediately started research to learn about how matches were found and I discovered that because I am a person with a mixed race and ethnic background (African American, Filipino and white) I would have a difficult time finding a full donor match.

While whites have a 75 percent chance of finding a full match in the existing bone marrow registry, African Americans only have a 19 percent likelihood of finding a match. African Americans comprise only 7 percent of the United States registry.

And, it is projected that by 2017 our likelihood of finding a match will only raise to 21 percent. Within the United States registry, the likelihood for finding a full match is higher for people of Mexican (37 percent), Chinese (41 percent), South Asian (33 percent), Hispanic Caribbean (40 percent) and Native American (52 percent) ancestry than for African Americans, but still significantly lower than the likelihood for whites.

Finding a non-related full match is difficult if you are a person of color, especially people of mixed race origin. Having a 100 percent match is crucial in predicting positive outcomes post-transplant. While the Seattle Cancer Care Alliance has been searching for a match, today, I still do not have a full bone marrow donor match and am moving forward with an alternative stem cell transplant using donated umbilical cord blood. My transplant for using cord blood was in September.

This is why we are organizing a national bone marrow donation registry campaign.I want to make my cancer matter, so my great friends stepped in to make this happen. Our goal is to have 4,000 new people registered by this effort. We need people of all backgrounds to become potential matches to help people like me live.

I am a professor of sociology and teach about social stratification, inequality and racial outcomes in institutional processing.I research class and racial differences in criminal justice processing and outcomes. I am the daughter of a black and Filipino man, wife to a black man, sister to black men, and mother of a black son and daughter.I live in the United States and, as many of us know, understand the racial inequalities in our broader society.Many times I feel overwhelmed about the lack of ability to make institutional differences, be it in our systems of education, criminal justice and health care.

Yet, when it comes to bone marrow donation, and other blood products and organ donation, we can make a difference. We can, for ourselves, save ourselves. Becoming involved in donation empowers us in a way like no other to alleviate health care disparities.

You can learn a lot about my story and this campaignatteamalexes.com. We had bone marrow registries in five cities last fall Seattle, Los Angeles, Houston, Washington, D.C., and New York.

Please consider signing up for the bone marrow registry. You can literally be a superhero and save someones life.

Dr. Alexes Harris is a professor of sociology at the University of Washington. This essay was originally published on her personal website.

I'm a woman of color with cancer. Here's why I can't find a bone ... - KUOW News and Information

Dodgers left-hander Rich Hill put some distance between himself and his spring of discontent Friday night, while Angels right-hander Garrett Richards put the finishing touches on his spring time of renewal.

Hill allowed four hits in 3 2/3 scoreless innings in a 3-1 exhibition victory at Angel Stadium, striking out two and walking one, a marked contrast from the 8.03 earned-run average he posted in five Cactus League starts, when he walked 14 and struck out 13 in 12 1/3 innings.

Hill said he was not particularly worried about his spring numbers. After all, he posted an 11.25 ERA last spring, then a 2.12 ERA during the season. Still, he was pleased with his performance Friday.

Everything is going in the right direction, he said. Today was a good outing, a good way to finish up spring training.

He said his curve and slider were the sharpest they had been all spring.

It was pretty weak contact throughout the game, he said. I think thats an indication of how the ball is coming out of your hand.

Richards allowed one run and two hits in four innings, striking out three and walking one in a 57-pitch tuneup for his regular-season debut Wednesday in Oakland.

His only blemish was a 1-and-1 slider that Justin Turner lined over the left-field wall in the fourth for a solo home run, giving the Dodgers third baseman, who is batting .385, a team-leading four homers and 16 runs batted in for the spring.

That Richards will open the season in the rotation is something of a miracle considering his setback last spring. He tore the ulnar collateral ligament in his right elbow in May and seemed headed for Tommy John ligament-replacement surgery.

Instead, he opted for stem-cell therapy, in which stem cells from his own bone marrow were injected into his elbow. A procedure that didnt work for teammate Andrew Heaney worked for Richards, who pitched in the instructional league last fall and has looked strong this spring, his fastball clocked in the 96-mph range.

I just feel very blessed, very thankful, for my teammates, who stood by me the whole time, for our training staff and doctors, Richards said. Everybody did such a great job with me, and I really appreciate it. Its been a long time, and Ive got to watch a lot of baseball, so its good to be out there competing again.

Richards said any doubts about the integrity of his elbow were eliminated in the instructional league. He had to overcome a similar mental hurdle in the spring of 2015 when he returned from major left-knee surgery.

I feel normal, Richards said. My body is finally feeling complete again. Im over the knee, my arm feels good.

Richards only concession to the elbow injury will be a pitch limit that the Angels hope to keep at around 100. A workhorse by nature, Richards threw 118 pitches and 115 pitches in consecutive April games last season.

I dont think well see 110-pitch outings from Garrett, but theres nothing to say he wont pitch deep into games, Angels Manager Mike Scioscia said. I think the extremes with Garret are something well avoid. Early in the season, were not going to see him throw 115 pitches. It just doesnt make sense.

The Dodgers were encouraged by Hills command Friday night, when he walked one of 16 batters after walking 14 of 58 batters in Arizona. He struck out Albert Pujols looking at a looping curve to end the first. He pitched out of a two-on, two-out jam in the second and retired the side in order in the third.

Left fielder Andrew Toles helped Hill with a running, lunging catch of Jefry Martes drive to the wall in the fourth, and Hill finished his night by striking out Danny Espinosa looking at a full-count curve.

The Dodgers scored twice off Angels reliever Kirby Yates in the eighth when Erick Mejia and Franklin Gutierrez led off with doubles and Cody Bellinger hit a two-out RBI double.

Angels right-hander Blake Parker may have solidified a bullpen spot when he struck out the side in the ninth, extending his consecutive strikeout string to 17 batters.

Dodgers closer Kenley Jansen struck out two of three in the fifth, and probable Angels closer Cam Bedrosian retired the side in order in the seventh, giving him nine scoreless innings this spring.

Having someone elses marrow or stem cells is called a donor transplant, or an allogeneic transplant. This is pronounced a-low-gen-ay-ik.

The donors bone marrow cells must match your own as closely as possible. The most suitable donor is usually a close relative, such as a brother or sister. It is sometimes possible to find a match in an unrelated donor. Doctors call this a matched unrelated donor (MUD). To find out if there is a suitable donor for you, your doctor will contact The Anthony Nolan Bone Marrow Register.

To make sure that your donors cells match, you and the donor will have blood tests. These are to see how many of the proteins on the surface of their blood cells match yours. This is called tissue typing or HLA matching. HLA stands for human leucocyte antigen.

Once you have a donor and are in remission, you have your high dose chemotherapy and radiotherapy. A week later the donor comes into hospital and their stem cells or marrow are collected.

You then have the stem cells or bone marrow as a drip through your central line.

If you've had a transplant from a donor, there is a risk of graft versus host disease (GVHD). This happens because the transplanted stem cells or bone marrow contain cells from your donor's immune system. These cells can sometimes recognise your own tissues as being foreign and attack them. This can be an advantage as the immune cells may also attack cancer cells left after your treatment.

Acute GVHD starts within 100 days of the transplant and can cause

If you develop GVHD after your transplant, your doctor will prescribe drugs to damp down this immune reaction. These are called immunosuppressants.

Chronic GVHD starts more than 100 days after the transplant and you may have skin rashes, diarrhoea, sore joints and dry eyes. Your doctor is likely to suggest that you stay out of the sun because GVHD skin rashes can often get worse in the sun.

There is more detailed information about graft versus host disease.

JEROMESVILLE Heidi Steiber was 27 years old when she was diagnosed with Multiple Sclerosis.

MS is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body, according to the NationalMultiple SclerosisSociety.

"I've experienced various symptoms," Steiber said. "Loss of vision, my left and right hands and left leg don't work very well."

MS is a progressive ailment, Steiber added, which means the damage the disease causes can not be corrected.

Now, 15 years later, the 42-year-old Steiber is hoping to raise enough money to spend a month in Puebla, Mexico to undergo a hematopoietic stem cell transplant.

HSCT is a transplant of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood.

Steiber applied for a similar program in Chicago, but was turned away because they wanted to research MS patients who have had the disease for 10 or less years.

The treatment will cost $55,000 and will keep Steiber in isolation for a month, she said. The treatment will destroy her immune system after her stem cells are taken from her marrow. After the immune system is removed the stem cells will be replaced into her body. She hopes to make her appointment on June 19 at Clinica Ruiz

"It's like Heidi 2.0 or Heidi rebooted," she joked.

She is using a crowd sourcing website to gather donations. So far, she has been excited by the results in one month, raising $32,000 of the $70,000 she is looking for to pay for her treatments and the following recovery. Steiber said her insurance will not contribute to the medical expenses.

"People have been extremely generous. One of my donators did a matching donation, so I raised $3,000 in a day-and-a-half.

Steiber, now residing in Raleigh, North Carolina, will be heading back to her hometown of Jeromesville to the American Legion for a benefit dinner, May 13. It will run from 3 p.m. to 10 p.m.

"You know the expression, it takes a village? That's the village they were talking about Jeromesville," the Hillsdale High graduate said. "It's amazing to have people coming together for you."

Adelaide woman Kate Rafertys son just started school, her daughter is two.

She doesnt like to speak about it with her doctors, but she may not get the chance to see them grow up.

Ms Raferty has a severe form of Leukaemia, which relapsed early in 2017.

She needs a life-saving bone marrow transplant a simple one-day procedure for the donor but of the millions of registered donors around the world, none are a match.

It was a bit hard to absorb because everything happened so fast when I was first diagnosed, she told SBS.

They focused on my sister being a match, and that took weeks to work out that she wasn't a match.

Only about 30 per cent of patients are able to find a match within their family - the chance of a single sibling being a match is 25 per cent.

At about the same time, they told me there wasn't a match worldwide, but never really worked out or advised why, MsRaferty said.

The likely reason is as uncomfortable one Ms Rafertys mother is Hungarian and her father is a white Australian.

The unique background is an inherent part of what makes Kate Raferty who she is, but it may have doomed her chances of finding a donor.

Bone marrow transplants require a partial genetic match relating to an array of genes known as the HLA system - family members are the best chance of a match, but failing that it's likely a donor will have to be found from people with a similar ethnic background.

People like us who have migrated to Australia, or are children of those who migrated and help make up multicultural Australia, have one of the worst chances of finding a match, Ms Rafertysaid.

Paul Berghoffer, Operations Manager with the Bone Marrow Donor Centre, says that while donor matching is based on a range of factors, a HLA match is critical - it's the system which your immune defences use to distinguish your own cells from foreign cells.

You inherit half of your HLA type from your mother and half from your father, and because it is an entirely inherited trait, we find there are HLA clusters within particular ethnic groups," he said.

Within Australia's 170,000-strong donor pool, northwest Europeans are probably over-represented, he said.

The challenge for donor registries in Australia and around the world is to build genetically diverse registries that are reflective of those who need help."

While factors vary case to case, those with a mixed genetic background, such as Kate Raferty, can have even rarer HLA types.

Looking at the law of averages, its definitely more challenging for people of mixed backgrounds to find a HLA match," he said.

"Given there are roughly 29 million donors registered world-wide, the fact that people still can't find a match just stands to show how variable HLA types are."

The answer, he says, is recruitment focused onethnic minorities and people with mixed backgrounds.

Kate Raferty and her husband and children, Christmas 2014.

In her desperation to stay alive to see her children grow up, Ms Raferty has taken to social media to raise awareness and increase donor registration.

Our cure is out there in someone else in the world, we just need them to register, she said.

The Raferty family isnt the only one looking.

Tania in South Australia has a mixed Balkan background.

Baby Ruby in the UK has a mixed Latin American background.

Six-month-oldAustin in the UKis of mixed Polish background.

Five-year-old Valerie in the UK has an African background.

Each family is desperate to find a match, andthey work with each other as part of an international drive to increase the genetic diversity of registered donors.

I am determined, determined to ask each and every one of you to help to save people like my son by signing up to become a stem cell donor for patients in need, said baby Austins father, Lewis.

Some campaigns have signed up thousands of extra donors, and turned up matches for multiple other patients.

Because people are often unaware of the diversity of their own genetic make-up, their campaigns target people very broadly.

My mum is from Hungary but thinks her grandma was from Czechoslovakia, Ms Rafferty said.

Possibly also any bordering country might share the same tissue types.

While doctors have toldMsRafterty her chances of finding a match are slim, she remains optimistic.

Others have found their matches by campaigning like this, but sadly others have died in their search, she said.

Enrolled in a drug trial and receiving blood cord transplants, she now has some extra time with her children, but she says her only hope of a cure is a transplant.

Someone with mixed Jewish-Chinese heritage just found their match, she said, so we live in hope.

You can join Australian Bone Marrow Donor Registry if you are aged between 18 and 45 years, in good health and meet the eligibility criteria. Joining the registry requires a blood test. If you are found to be a match, donating can be done through a blood donation or a relatively simple day procedure.

Why mixed-race minorities struggle to find life-saving transplant matches - SBS

BRADENTON, Fla. By now, the time line for recovery from Tommy John surgery is familiar even to the casual baseball fan. It takes at least a year, usually more. It takes tedious, monotonous work on the part of the player.

Alternatives exist, but until now their use among established major leaguers has been limited if tried at all. This season could provide a referendum on two of them. One surgical procedure could cut the recovery time in half. Another treatment could help a player avoid surgery altogether.

I think it can definitely help the game, right-hander Seth Maness, who had a modified elbow ligament surgery in August, said by phone from spring training in Arizona. But the circumstances have to be right.

Maness had a surgery on his right elbow known as a primary repair or primary brace. The procedure reattaches the elbows ulnar collateral ligament to the bone with collagen-coated Arthrex tape. Los Angeles Angels starter Garrett Richards received a stem cell injection into his right elbow to heal his damaged UCL. So far, its working.

The last thing you want to do is have surgery, and if you do what your body does naturally, thats going to be stronger than any replacement surgery, Richards said, also by phone from spring training in Arizona. I just hope that this further gives guys a little bit of knowledge that you have options.

Neither procedure will replace Tommy John. Stem cells dont work in every case, and if the UCL is torn across the middle of the ligament, it needs to be replaced. The sample size for both is also small. But both provide options involving less recovery time for pitchers whose injuries fit a certain profile.

Maness, 28, spent four seasons pitching out of the St. Louis Cardinals bullpen and signed a minor league contract with the Kansas City Royals in February. Maness ligament had pulled away from the bone rather than tearing across the middle. Instead of needing a full Tommy John surgery, which requires grafting a tendon from the wrist or hamstring into the elbow to replace the UCL and at least a year of recovery, Maness was a candidate for a primary repair.

Really this primary brace technology had been used more widely in Europe, particularly for ligament injuries of the knee and the ankle, said Dr. George Paletta, St. Louis Cardinals head orthopedic surgeon who performed Maness surgery. So the concept or the idea was, OK, its working well there, is there a way to adapt it to the elbow?

Paletta had done roughly 60 primary repairs on amateur pitchers prior to operating on Maness and saw an average recovery time of 6 months. That background helped him establish three criteria he needed a young pitcher, an otherwise healthy ligament and, most importantly,the ligament needed to pull off the bone on one end rather than tear in the middle.

Weve had a lot of experience with ligaments healing directly to bone and we have a good understanding of that timetable, so we knew that by about 12 weeks after surgery, this repair should be pretty well healed and pretty solid at that point, Paletta said.

Cardinals reliever Mitch Harris also had the primary repair, as did a third pitcher with major league experience, according to the St. Louis Post-Dispatch, with whom Maness first discussed the procedure in January. Cardinals non-roster outfielder/pitcher Jordan Schafer had the procedure this month.

The UCL in Richards right elbow had a tear running along the ligament, not across it. He sought second opinions from noted orthopedic surgeons Dr. James Andrews and Dr. Neal ElAttrache.

Dr. Andrews pretty much told me, Hey Garrett, if you were my son, I would try the stem cell first, Richards said.

Doctors removed stem cells from his pelvis and injected them into his elbow, in hopes the cells would heal the UCL. Stem cells, extracted from bone marrow, are able to develop into multiple different tissues and can promote healing.

It just feels tight. Youre putting fluid into a place that pretty much doesnt have any room for any more fluid, Richards said of the injection. If you can imagine youre just overfilling a certain area with this nice special sauce.

Teams sometimes use platelet-rich plasma injections, where blood is spun in a centrifuge to isolate growth factors Takashi Saitos PRP injection in 2008 was believed to be the first for a major league pitcher, and Masahiro Tanaka also has pitched successfully with a partially torn UCL after PRP treatment but stem cells are less common. Bartolo Colon, soldiering into his 20th major league season at 43 years old, had a stem cell treatment in 2010. Boston Red Sox left-hander Drew Pomeranz had a stem cell injection in his elbow this winter to address lingering soreness.But Pomeranz went on the disabled list Thursday with left forearm flexor strain.

It doesnt always work. Richards teammate, lefty Andrew Heaney, needed Tommy John last summer after stem cells didnt do the trick.

Richards six-week exam showed significant growth. His three-month check showed even more. He reported no issues this spring, his high-90s mph fastball is back and he is on track to open the season in the rotation.

Everything feels great, Richards said. Basically I took the year off, let my arm heal and now Im back doing what I always do. I just feel refreshed.
