Bone Marrow Stem Cells Comments Off on Engineered bone marrow could make transplants safer – Science Daily | May 14th, 2017

12 May 2017 Bone marrow: be someones match A bone-marrow donation is not a scary procedure and doesnt involve drilling into your bones. We found out more.

Unfortunately many people still believe that donating bone marrow means doctors will need to drill into your bones. The reality is the donation process requires no surgery, no general anaesthetic and no drilling.

South African patients who have leukaemia or other blood disorders need a life-saving stem cell transplant and rely on the South African Bone Marrow Registry (SABMR) to find a match.

The challenges faced in growing the SABMR lies in the sentence itself, says Alana James, CEO of the Sunflower Fund. Its called The South African Bone Marrow registry, so when people see the word bone marrow they go Oh no I cant do that, it will hurt!

Understanding bone marrow

Bone marrow is found inside your bones its a soft, fatty tissue that helps with the production of red blood cells (to carry oxygen), white blood cells (to find infection) and platelets (to prevent bleeding). Some of the cells in the bone marrow can be pushed into the blood stream, where it can be collected and then used to help someone in need of a donation.

Real-life hero

Carey Symons, a blood stem cell donor and long-time support of The Sunflower Fund, was on the registry for 10 years before she was called to help a leukaemia patient.

The stats of a perfect match are 1 in 100 000 so you can only imagine my joy in being that 1 in 100 000 and that I was able to contribute to giving someone a second chance.

She travelled from Durban to Mediclinic Constantiaberg in Cape Town where she had a series of painless Neupogen injections that helped stimulate the production and release of blood stem cells.

Three days of injections later she was able to begin the donation process.

1. Two needles (similar to those used when you donate blood) were inserted in each arm. 2. Blood was drawn from one arm and circulated through a cell-separator machine. 3. Her stem cells were collected and the remaining blood was returned through the other arm.

Typically, the donation process takes between four and six hours.

I realised that the day I signed as a donor, I was only hoping to make a difference. I will never know whose life I made a difference to, and part of that mystery excites me. Its a blessing to give without knowing and without being thanked.

Harsh reality

There are just under 74 000 donors on the registry, but at least 400 000 are needed.

We definitely still have a mountain to climb and are committedly doing so. Registering as a donor on the SABMR is a simple process and can be very rewarding, says James. You could be someones perfect match.

Be someones 1 in 100 000

Signing up to be a donor is simple- if you do meet the criteria, you will receive a reference number and form to fill out. Next, youll go to your nearest Donor Recruitment Clinic where theyll take two test tubes of blood.

Your blood is analysed and put onto the national database. Unfortunately the tissue typing test is expensive (it costs R2 000) but you can make a donation to help free up their funds.

Youll receive your donor card in six to eight weeks, and if youre ever a match for a patient, you will be called.

A new biomimetic bone tissue may help improve bone marrow transplants.

Engineers at the University of California San Diego have developed a bone-like implant that eliminates the need for donor cells to wipe out the hosts pre-existing cells, by allowing donor cells the space to live and grow.

Weve made an accessory bone that can separately accommodate donor cells. This way, we can keep the host cells and bypass irradiation, bioengineering professor Shyni Varghese, from the UC San Diego Jacobs School of Engineering, said in a statement.

The implants are made of a porous hydrogel matrix that contains calcium phosphate minerals in the outer matrix and donor stem cells that produce blood cells in the inner matrix.

The researchers successfully tested the bone tissues in mice and the donor cells survived for at least six months, while supplying the mice with new blood cells.

The structures matured into bone tissues of the mice that have a working blood vessel network and a bone marrow inside that supplies new blood cells. After a month the implanted marrow contained a mixture of host and donor blood cells, which remained circulating in the bloodstream even after 24 hours.

In the future, our work could contribute to improved therapies for bone marrow disease, Yu-Ru (Vernon) Shih, a research scientist in Vargheses lab and the studys first author said in a statement. That would have useful applications for cell transplantations in the clinic.

The researchers also took stem cells from the implanted marrow and transplanted them into another group of mice with their marrow stem cells eradicated by radiation and drugs. The transplanted cells diffused into the bloodstream of the mice in the second group.

Were working on making this a platform to generate more bone marrow stem cells, Varghese said.

According to Varghese, the implants could only be used in patients with non-malignant bone marrow diseases, where there arent any cancerous cells that need to be eliminated.

The researchers said this discovery indicates that implanted marrow is functional and donor cells can form and survive for long periods of time in the presence of host cells. They also said that the host and donor cells can travel between the implanted marrow and the hosts circulating blood through the blood vessel network formed in the implanted bone tissue.

South African patients suffering from Leukaemia and other blood disorders who need a life-saving stem cell transplant, rely on the South African Bone Marrow Registry (SAMBR) to find a donor who is a genetic match.

But, the untrue and frightening belief that donating blood stem cells, or bone marrow, involves drilling through bones is a common misconception and is one of the challenges faced in growing the SAMBR.

These misconceptions, often stopping people from registering to become donors and giving someone the hope of life.

The Sunflower Fund educates, raises funds and recruits potential blood stem cell donors to this registry and pays for the tissue typing test cost for each person who joins.

The fund also prioritises educating people on the truths of becoming a donor and works hard to debunk any myths that exist. Sometimes it is just the words themselves that act as barriers. The challenges faced in growing the SABMR lies in the sentence itself, Alana James, CEO of the Sunflower Fund said. Its called The South African Bone Marrow registry, so when people see the word bone marrow they go Oh no I cant do that, it will hurt!.

Blood stem cell donor and long-time supporter of the Sunflower Fund Carey Symons shares her own story at events and conferences, spreading the message that the process of potentially saving a life is not as scary as we might think, encouraging others to do the same.

The stats of a perfect match are 1 in 100 000 so you can only imagine my joy in being that 1 in 100 000 and that I was able to contribute to giving someone a second chance, Symons said, who was called ten years after joining the registry to donate her stem cells to a patient suffering from leukaemia.

The Durban mother travelled to Constantiaberg hospital in Cape Town, to begin a series of painless Neupogen injections which stimulate the production and release of blood stem cells.

After three days of injections, she was ready to begin the donation process: Two needles, similar to the ones used when donating blood, were inserted; one in each arm. Blood was drawn from one arm, circulated through a cell-separator machine where her stem cells were collected and the remaining blood was returned through the other arm.

After 4-6 hours, the life-saving stem cells were harvested and for Symons, the process was over.

She said she often thought about the person she donated her stem cells to and sometimes wonders who they were. I realised that the day I signed as a donor, I was only hoping to make a difference. I will never know whose life I made a difference to, and part of that mystery excites me. Its a blessing to give without knowing and without being thanked.

There are just under 74 000 donors on the registry, but at least 400 000 are need. We definitely still have a mountain to climb and are committedly doing so. Registering as a donor on the SABMR is a simple process and can be very rewarding, James explained. You could be someones perfect match.

A project of the university's transfusion medicine department, the stem cell bank would roll out stem cell therapy to patients of thalassemia and sickle cell anaemia.

A public sector stem cell bank is set to come up at UP's King George's Medical University. A project of the university's transfusion medicine department, the stem cell bank would roll out stem cell therapy to patients of thalassemia and sickle cell anaemia. The proposal is awaiting clearance from state department of medical education.

Stem cells are found in human bone marrow and can be derived from the umbilical cord which contains blood vessels that connect baby in the womb to the mother to ingest nutrition required for development.

Research on the therapeutic use of stem cells is underway in US, Europe, China, South East Asia besides India. In UP, Sanjay Gandhi Post Graduate Institute of Medical Sciences (SGPGIMS) and KGMU are both trying to explore the potential of stem cells to treat various health problems. SGPGI has, so far, restricted itself to use of allogenic (stem cells derived from bone marrow of a person), while KGMU has used stem cells derived from the umbilical cord.

KGMU has sustained access to umbilical cord because of a very developed obstetrics and gynaecology department. The proposal is worth Rs 9 crore including infrastructure cost. Stem cell bank promises to become financially self-sustaining within 2-3 years of inception.

Be The Match BioTherapies LLC, a recently created subsidiary of the Minneapolis-based National Bone Marrow Program/Be The Match, this month emerged as a biotechnology venture investor with its participation in a $50 million financing round for a Massachusetts stem cell company. And, its leaders say, it likely wont be the last time the 17-month-old nonprofit spinoff will take part in venture funding to support the commercialization of biotech related to NBMP/Be The Matchs mission of advancing cell therapies for leukemia patients and others needing bone marrow/stem cell transplants. NMDP/Be The Match moved its 995 employees into a newly constructed headquarters building in the North Loop in December 2015. It runs a network of more than 486 organizations that support marrow transplant worldwide, including 178 transplant centers in the United States and more than 45 international donor centers and cooperative registries. Wholly-owned subsidiary Be The Match BioTherapies was among the Series B investors for Magenta Therapeutics of Cambridge, Massachusetts, a biotech company developing therapies to improve and expand the use of curative stem cell transplantation for more patients. Other participants in the oversubscribed round included new lead investor GV (formerly Google Ventures) and existing investors such as Atlas Venture, Third Rock Ventures, Partners Innovation Fund and Access Industries. A major feature of the Magenta deal was also Be The Match BioTherapies new involvement as a strategic partner for the company, under which the two sides will explore opportunities to work together across all of Magentas research efforts, from discovery through clinical development. Magentas lead drug candidate is MGTA-456, which it claims is capable of expanding the number of cord blood stem cells available for transplantation, thus achieving superior clinical outcomes compared to standard transplant procedures. John Wagner M.D., executive medical director of the Bone Marrow Transplantation Program at the University of Minnesota is leading the research. The strategic agreement allows Magenta to leverage Be The Match BioTherapies capabilities, including its cell therapy delivery platform, industry relationships, clinical trial design and management and patient outcomes data generated from the parent organization. According to NMDPs 2015 annual report, Be The Match BioTherapies was established on Dec. 4, 2015, and authorized to do business as a nonprofit limited liability company. The report said it was anticipated the subsidiary would conduct certain business in the field of cellular therapy consistent with the nonprofit mission of its parent corporation, National Marrow Donor Program, but outside the scope of NMDPs customary core business. Led by NMDP Chief Financial Officer Amy Ronneberg, Be The Match BioTherapies says it is making the parent organizations capabilities available to commercial entities developing new allogeneic and autologous cellular therapies. For example, it says it is collaborating with an unnamed biotech company to design a donor identification and cell harvest strategy for white blood cells from donors with specific human leukocyte antigen types. When asked if the subsidiarys venture investment into Magenta Therapies was a sign that it is staking out ground as a stem cell industry investment player, company spokeswoman Melissa Neill told TCB its indeed a scenario that could play out again. We are continually looking for ways to advance science and research in new cellular therapies, she said in an email. In the future, this might mean investments in or additional partnerships with companies whose goals align with our goal of developing and delivering cellular therapies to positively impact patients lives.

Thanks to advances in medicine, bone marrow transplants are no longer the last resorts they once were. Every year, thousands of marrow transplants are performed, a common treatment for ailments from bone marrow disease to leukemia. But because they first require a patient undergo radiation to kill off any existing bone marrow stem cells, marrow transplants remain incredibly hard on a patient.

Now, engineers at the University of California San Diego have developed a synthetic bone implant with functional marrow able to produce its own blood cells. So far, researchers revealed in a paper published in the Proceedings of the National Academy of Sciencesthis week, they have successfully tested the engineered bone tissues in mice. But one day, those biomimetic bone tissues could provide new bone marrow for human patients in need of transplants, too.

The implant does away with the need for radiation by giving donor cells their own space in the body to grow. Inside the implant, there is no threat of those cells being overtaken by the bodys native stem cells.

In mice, the researchers implanted the synthetic bone tissues with functional marrow under the skin. After six months, those donor cells were still alive and had begun supplying the mice with new blood cells.

The implants were designed to replicate the long bones in the body, with an outer bone compartment containing calcium phosphate minerals to build bone cells, and an inner area for donor stem cells that produce blood cells.

When implanted, they grew into bone tissues with working blood vessel network and functional bone marrow that supplied the body new blood cells. After 24 weeks, researchers found a mix of host and donor blood cells was still circulating in the bloodstream of the mice.

A treatment based on this technology would only work for patients with non-malignant bone marrow diseases, like aplastic anemia, a condition where the body cant make enough platelets and blood cells. Thats because while the technique can replenish types of cells that are lacking, it cant doing anything to fight off cells that have mutated and are spreading. Cancer patients would still need need to undergo radiation therapy to have their cancerous cells wiped out.

Much more research is needed, of course, before these implants are ready to make their way into human patients. But whats exciting here is that the synthetic bone tissues were not only functional, they allowed donor marrow to grow and survive for many weeks in the presence of host cells, and for the products of that marrow to make their way into the bodys circulatory system. Pretty neat.

Sensational 8-Year-Old Violinist Living With Painful Disease

WINSTON-SALEM, NC Its hard to walk through life without hitting a sour note or two. In Winston-Salem, there's a young boy with talent beyond his years and a disease that nearly crippled him. His father gave up his career to take care of his son and to get him healthy.

We only listen to classical music at home, said Lucas Sant, a father of three living in Winston-Salem. He sits with his youngest, Helen, 2, on his lap. His second oldest daughter, Maria-Anita, 7, sits on his right and his only son, Caesar, 8, sits to his left.

Hes telling WFMY News 2s reporter, Hope Ford, about his sons remarkable talent.

When he was just a baby, we bought Baby Einstein, and you know, they have the animals and the music. So, we bought him a little toy piano, Lucas began. And one day, when he was seven months old, we heard this music coming from the room. It sounded like the toy piano, but it was the music from the Baby Einstein.

Lucas turned to his wife, Aline, with a knowing smile and said, We have our work to do with this boy.

Videos uploaded to YouTube, show a baby Caesar, waving his arms along to classical music such as Beethoven, almost as if he were conducting a symphony.

Violin lessons started the age of two.*

He started playing Vivaldi. He would pick up things very quick, said Lucas. Everybody was very impressed.

GoFundMe

All the Sant children are homeschooled and it would be no surprise to learn Caesar is just as brilliant with a pencil as he is with an instrument. The young boy is ahead in math and other subjects and earned a black belt in karate at 5-years-old.

Lucas sat in his seat, as baby Helen decided she wanted to leave the room to see what her mom was up to. As she ran into the next room, Lucas continued his story.

Immediately, he started to get sick. Before five, he had the first stroke.

Caesar has sickle cell anemia.

You never know anything until you experience, Lucas said in a soft voice.

Sickle cell anemia is a blood disease. Normal red blood cells are round and flexible to carry oxygen throughout the body. Caesars blood cells are sickle-shaped or bent and get stuck, slowing the flood of blood and oxygen.

Lucas explained, Its different. Its my son and I never seen this thing.

Caesar, who up until this point sat quietly next to his father with his violin in his lap said, I feel bad. I dont feel good when Im sick.

The curly haired violinist has three strokes before the age of six. The first two left his arms weak, but he rebounded, performing the National Anthem at the Grasshoppers Game in 2013.

The third one was a different stroke, said his dad.

Caesar lost feeling in his arms and legs after his third stroke, leaving him partially paralyzed for nearly six months.

At first, even his eyes was not moving. But, when he did wake up, all of a sudden your son not walk, not run, not stand up, Lucas said as if he was still trying to make sense of it all.

Doctors told the Sant family, It is very unlikely your son is going to die but do not expect much from him.

Lucas paused for a moment and continued, But the good thing there, you really meet God. What am I supposed to do God? Please tell me.

The only thing that seemed right at the time, was for Lucas to give up his career. The father of three was a neuroscientist at Wake Forest Baptist Medical Center.

Forget about my life. I said, Im going give my life to this boy.

Young Caesar in the hospital. (Photo: Sant family)

The Sant family built a small play gym in the basement of their home. Here, Lucas would help Caesar with physical therapy, as they could not afford to hire someone full time to help him regain strength and movement in his arms and legs.

Some days and good and some are bad. Three years after his last stroke, Caesar still winces in pain as he goes through his exercises. But, he finds moments to laugh with his siblings, who cheer him on. And as an 8-year-old, he is a little hard to get under control. For Lucas, the physical therapy takes a toll on his as well.

First, Im not a physical therapist. I have a lot of patience but its very hard for you see your son one way, said Lucas. Sometime, we have to take breaks because it is difficult and it sometimes weighs on my own health.

But, once again, Caesar regained his strength, returning to the Grasshoppers stadium in 2017 to perform the National Anthem once again.

Every month, Caesar and his family travel to Charlotte for blood transfusions to lower the risk of Caesar having another stroke. He'll have to do this for the unforeseeable future and there are risks.*

Frequent blood transfusions can lead to iron overload which is sometimes fatal. Caesar's family is trying for a bone marrow transplant which has a higher percentage of curing his sickle cell disease.

They have a donor- his baby sister, Helen.

As if she knew her name had been mentioned, the young girl, called the boss of the family, walked back into the room, sharing bites of her rice with her siblings and father.

Lucas and his wife wanted another child, but they also wanted to ensure the next child would not have the sickle cell anemia trait. they also wanted to ensure they would have a 100 percent genetic match for Caesar's procedure.

Maria-Anita was also born with sickle cell anemia, but unlike her brother, has yet to experience any complications.

So, Aline got pregnant via in vitro fertilization. Doctors only planted cells that were a genetic match and only healthy cells were selected. Thus, Helen was conceived and at birth, her umbilical cord was collected.

Helen, was born sickle-cell free.

They took the stem cells from the umbilical cord and now they have perfect cells, to do the transplant on him, said Lucas.

The Sant family is trying to raise money for a bone marrow/stem cell transplant. The process is long and costly. According to Johns Hopkins, one hospital that specializes in bone marrow/stem cell transplants, they say the cost can run as high as $500,000.

However, sickle cell anemia can be cured with the procedure.

Offering her big brother another big of food, Helen, Caesars sisterly hero, smiled and ran off.

Lucas continued to explain the familys financial situation.

Its difficult, with me not having a job. But, we have had people help us along the way. But, we are still trying so hard to raise money for the surgery.

A GoFundMe account was started in 2013. To date, $38,000 has been raised. The family also started a website to give updates and sell merchandise to help raise funds as well.

Caesar still walks with a limp and must be careful when sitting down. Lucas looked at his son and said Were so happy because he got back. He got back, but the job is not done. Faith, hope, these things so real. Cause if dont have what you can do? You give up right there.

Caesar piped in again, Sometimes I tell my father, papa, I dont know when Im going to be back, but God is always with me.

Lucas isnt giving up. His hope, to have son healthy by 2018.

And Caesars hope?

I want to be a musician and a conductor.

*This story has been updated to correct information. Lessons for Caesar started at the age of 2 and 300ml of his blood is replaced every month during his blood transfusions.

So how did they come together? It was less than 3 years ago that Edwards received the toughest news anyone can receive from a doctor.

"I was then diagnosed with leukemia, a rare form of leukemia," said Edwards.

The treatment for this rare form of blood cancer included multiple rounds of chemotherapy and radiation.

"All in all, it was enough toxins to kill a person if you ask me," said Edwards.

Edwards was also hoping to find help from someone else's blood.

"We started the search through Delete Blood Cancer and found a match," said Edwards.

The goal was to find a donor with a similar genetic makeup who could give Edwards their stem cells.

"We tried to match my brother and sister, but unfortunately there were not. So, we kept the search until we could find a match. It was a little nerve-racking, said Edwards.

That's where Halfkann comes in.

"I got a letter that I can be a stem cell donor, and I must go to the clinic in Cologne," said Halfkann.

Halfkann was already previously registered having signed up after one of her coworkers became ill. Although no successful matches were found back in Germany, in Minnesota, Halfkann was exactly who Merissa was looking for.

"Daniela is the only match in the world," said Edwards.

The news that Halfkann could save a stranger's life in the United States delighted the soft-spoken German.

"I'm so happy. I'm grateful," said Halfkann.

The stem cell procedure was pretty simple. Daniela donated blood. The stem cells were filtered out, then sent to Merissa in Minnesota where they were injected.

"There's a lot of complications after the stem cell transplant that could've gone wrong. Fortunately it didn't, which made Daniela an even more perfect match than she already is," said Edwards.

When Edwards heard about the woman who extended her life, she connected with Halfkann online.

"At first we wrote email, and then we connected on Facebook," said Halfkann.

After just a few notes, it was quickly discovered that the two have more in common than the blood running through their veins.

"We like a lot of the same things. Both have 2 children. Both of our husbands are firefighters," said Edwards.

And Edwards continues to successfully battle cancer.

"Right now I am in remission. That doesn't mean that I'll necessarily be cancer-free, but knock on wood...that's the goal...that the cancer will never come back," said Edwards.

There was only one thing left for Edwards to do; meet the woman and family that saved her life. So just a few weeks ago, the pair met for the very first time at Duluth International Airport.

"She is so nice. She is so lovely. I'm so happy we can be here," said Halfkann.

In the ten days together, they and their families created many memories. Halfkann got a glimpse of the life Edwards is now able to hold on to, and it wasn't long before the pair found more in common.

"We seem to like the same things...fruity tea, crafting, sewing, just similar interests in hobbies. Another common interest, shoes," said Edwards.

Both husbands also enjoyed their time together. At the firehouse, Merissa's husband, Dennis, giving Daniela's husband, Stefan, a tour of some of the American rigs and a ride along during an emergency call.

Back at headquarters, the crew made a home-cooked dinner for Halfkann's family and someone else who helped make all of this happen: Amanda Schamper, a representative of the registry that matched Edwards and Halfkann.

"What we try to do is to raise awareness in all communities that this is a problem out there. People are searching for their donor match and can't find one," Schamper.

Schamper also showed everyone just how easy it is to sign up to be a bone marrow and stem cell donor.

"We do have a statistic that nearly 14,000 patients are told that they needed a transplant each year, and less than half can't get one because they can't find a donor match on the registry, said Schamper.

During the visit, Edward's extended family threw a get-together in honor of Halfkann. Edward's sister-in-law Kris Hansen is just as grateful.

"Just to know that she's here and they've met each other, and that she can save a life...it's incredible. It's nice to be able to see her and her family and her two adorable daughters," said Hansen.

Through the countless hugs at the party, family members repeated one phrase that transcends all languages.

"I guess the biggest thing we have to say is Danka Daniella!" said Hansen.

"Thank you for saving my life. Thank you for letting me be a Mom. Thank you for coming here so I can meet you and meet your beautiful children and your husband," Edwards said to Halfkann.

And with thanks, comes gratitude.

"I'll forever be grateful to you. You will always be a part of my family." said Edwards.

And this bond that will last a lifetime.

"We're forever connected," said Edwards.

"Yes. Forever," said Halfkann.

Edwards says she and her family are making plans to visit the Halfkann's in Germany.

If you're interested in signing up to become a bone marrow or stem cell donor, it's free and only takes a few moments. A link to that website can be found here.

LUCKNOW: In what may come as a relief to over 1 lakh patients of thalassemia in India, a public sector stem cell bank is set to come up at UP's King George's Medical University here. A project of the university's transfusion medicine department, the stem cell bank would roll out stem cell therapy to patients of thalassemia and sickle cell anaemia. The proposal is awaiting clearance from state department of medical education.

Stem cells are omnipotent and can take shape of any cell inside the body. If infused in the pancreas, stem cells will become pancreatic while in the liver, they will become liver cells.

These are found in human bone marrow and can be derived from the umbilical cord which contains blood vessels that connect baby in the womb to the mother to ingest nutrition required for development.

Research on the therapeutic use of stem cells is underway in US, Europe, China, South East Asia besides India. In UP, Sanjay Gandhi Post Graduate Institute of Medical Sciences (SGPGIMS) and KGMU are both trying to explore the potential of stem cells to treat various health problems. SGPGI has, so far, restricted itself to use of allogenic (stem cells derived from bone marrow of a person), while KGMU has used stem cells derived from the umbilical cord.

Head of transfusion medicine department of KGMU, Prof Tulika Chandra said, "Several private sector stem cell banks like Life Cell and Cord Life India are operating in India but they serve only those who have deposited the baby's cord, while our bank will help everyone."

KGMU has sustained access to umbilical cord because of a very developed obstetrics and gynaecology department. The cord is gathered from the placenta in the uterus of pregnant women which nourishes and maintains the baby through the umbilical cord.

Sources in medical education department said the proposal is worth Rs 9 crore including infrastructure cost. "Stem cell bank promises to become financially self-sustaining within 2-3 years of inception," said a directorate officer.

Talking about why children with thalassemia and sickle cell anaemia were chosen, Chandra said, "Global literature shows umbilical cord stem cells can induce extraordinary results on such children. In fact, success rate is around 70-75% and higher score can be achieved if therapy is provided at an earlier age."

Sensational 8-Year-Old Violinist Living With Painful Disease

WINSTON-SALEM, NC Its hard to walk through life without hitting a sour note or two. In Winston-Salem, there's a young boy with talent beyond his years and a disease that nearly crippled him. His father gave up his career to take care of his son and to get him healthy.

Child Prodigy

We only listen to classical music at home," said Lucas Sant, a father of three living in Winston-Salem. He sits with his youngest, Helen, 2, on his lap. His second oldest daughter, Maria-Anita, 7, sits on his right and his only son, Caesar, 8, sits to his left.

Hes telling WFMY News 2s reporter, Hope Ford, about his sons remarkable talent.

When he was just a baby, we bought Baby Einstein, and you know, they have the animals and the music. So, we bought him a little toy piano, Lucas began. And one day, when he was seven months old, we heard this music coming from the room. It sounded like the toy piano, but it was the music from the Baby Einstein.

Lucas turned to his wife, Aline, with a knowing smile and said, We have our work to do with this boy.

Videos uploaded to YouTube, show a baby Caesar, waving his arms along to classical music such as Beethoven, almost as if he were conducting a symphony.

Violin lessons started the age of two.*

He started playing Vivaldi. He would pick up things very quick, said Lucas. Everybody was very impressed.

GoFundMe

All the Sant children are homeschooled and it would be no surprise to learn Caesar is just as brilliant with a pencil as he is with an instrument. The young boy is ahead in math and other subjects and earned a black belt in karate at 5-years-old.

A Painful Disease

Lucas sat in his seat, as baby Helen decided she wanted to leave the room to see what her mom was up to. As she ran into the next room, Lucas continued his story.

Immediately, he started to get sick. Before five, he had the first stroke.

Caesar has sickle cell anemia.

You never know anything until you experience, Lucas said in a soft voice.

Sickle cell anemia is a blood disease. Normal red blood cells are round and flexible to carry oxygen throughout the body. Caesars blood cells are sickle-shaped or bent and get stuck, slowing the flood of blood and oxygen.

Lucas explained, Its different. Its my son and I never seen this thing.

Caesar, who up until this point sat quietly next to his father with his violin in his lap said, I feel bad. I dont feel good when Im sick.

The curly haired violinist has three strokes before the age of six. The first two left his arms weak, but he rebounded, performing the National Anthem at the Grasshoppers Game in 2013.

The third one was a different stroke, said his dad.

Caesar lost feeling in his arms and legs after his third stroke, leaving him partially paralyzed for nearly six months.

At first, even his eyes was not moving. But, when he did wake up, all of a sudden your son not walk, not run, not stand up, Lucas said as if he was still trying to make sense of it all.

Doctors told the Sant family, It is very unlikely your son is going to die but do not expect much from him.

Lucas paused for a moment and continued, But the good thing there, you really meet God. What am I supposed to do God? Please tell me.

The only thing that seemed right at the time, was for Lucas to give up his career. The father of three was a neuroscientist at Wake Forest Baptist Medical Center.

Forget about my life. I said, Im going give my life to this boy.

The Sant family built a small play gym in the basement of their home. Here, Lucas would help Caesar with physical therapy, as they could not afford to hire someone full time to help him regain strength and movement in his arms and legs.

Some days and good and some are bad. Three years after his last stroke, Caesar still winces in pain as he goes through his exercises. But, he finds moments to laugh with his siblings, who cheer him on. And as an 8-year-old, he is a little hard to get under control. For Lucas, the physical therapy takes a toll on his as well.

First, Im not a physical therapist. I have a lot of patience but its very hard for you see your son one way, said Lucas. Sometime, we have to take breaks because it is difficult and it sometimes weighs on my own health.

But, once again, Caesar regained his strength, returning to the Grasshoppers stadium in 2017 to perform the National Anthem once again.

A Small Miracle

Every month, Caesar and his family travel to Charlotte for blood transfusions to lower the risk of Caesar having another stroke. He'll have to do this for the unforeseeable future and there are risks.*

Frequent blood transfusions can lead to iron overload which is sometimes fatal. Caesar's family is trying for a bone marrow transplant which has a higher percentage of curing his sickle cell disease.

They have a donor- his baby sister, Helen.

As if she knew her name had been mentioned, the young girl, called the boss of the family, walked back into the room, sharing bites of her rice with her siblings and father.

Lucas and his wife wanted another child, but they also wanted to ensure the next child would not have the sickle cell anemia trait. they also wanted to ensure they would have a 100 percent genetic match for Caesar's procedure.

Maria-Anita was also born with sickle cell anemia, but unlike her brother, has yet to experience any complications.

So, Aline got pregnant via in vitro fertilization. Doctors only planted cells that were a genetic match and only healthy cells were selected. Thus, Helen was conceived and at birth, her umbilical cord was collected.

Helen, was born sickle-cell free.

They took the stem cells from the umbilical cord and now they have perfect cells, to do the transplant on him, said Lucas.

The Next Step

The Sant family is trying to raise money for a bone marrow/stem cell transplant. The process is long and costly. According to Johns Hopkins, one hospital that specializes in bone marrow/stem cell transplants, they say the cost can run as high as $500,000.

However, sickle cell anemia can be cured with the procedure.

Offering her big brother another big of food, Helen, Caesars sisterly hero, smiled and ran off.

Lucas continued to explain the familys financial situation.

Its difficult, with me not having a job. But, we have had people help us along the way. But, we are still trying so hard to raise money for the surgery.

A GoFundMe account was started in 2013. To date, $38,000 has been raised. The family also started a website to give updates and sell merchandise to help raise funds as well.

Caesar still walks with a limp and must be careful when sitting down. Lucas looked at his son and said Were so happy because he got back. He got back, but the job is not done. Faith, hope, these things so real. Cause if dont have what you can do? You give up right there.

Caesar piped in again, Sometimes I tell my father, papa, I dont know when Im going to be back, but God is always with me.

Lucas isnt giving up. His hope, to have son healthy by 2018.

And Caesars hope?

I want to be a musician and a conductor.

*This story has been updated to correct information. Lessons for Caesar started at the age of 2 and 300ml of his blood is replaced every month during his blood transfusions.

Its our goal for this to be a normal NHS procedure, so everyone who has a heart problem [and could benefit from this] will be able to. There are few downsides because theres no rejection as theyre your own stem cells, and every patient who has successfully had this treatment ends up taking less medication.

Jenifer is overjoyed with the progress already made, and knows that Ian would be, too, had he lived to tell his story.

For Ian, the treatment gave him an extra three years of life, but in 2006 he died from heart failure, at the age of 70.

He would be so thrilled, says Jenifer. His concern would be were not doing it quick enough, because for him everything had to be done immediately. But to have achieved this much well, the medical world says weve done it all in a very short space of time.

The couple spent their final years together alternating between their family home in St Johns Wood, north London, and a holiday home in Miami.

They were both each others second spouses, having married in 1980 after a whirlwind romance in Cannes Jenifers first husband had died, while Ian had divorced his wife and did not have children together. But Ian had two children from his first marriage, as well as two young grandchildren who he was able to spend those extra three years with.

Most of the Gulfs thalassemia sufferers can now be cured of the debilitating blood disease through a safe and effective bone marrow transplant procedure performed in the US, said one of the worlds leading pediatric hematologists, ahead of International Thalassemia Day on May 8.

Thalassemia is a genetic blood disease, common across the wider Middle East and South Asia, in which victims are not able to make enough hemoglobin a necessary component in healthy red blood cells, carrying oxygen to all parts of the body and, thus, suffer from severe anemia and eventual organ failure, and, ultimately, premature death.

The condition is typically treated with life-long, cost-prohibitive supportive care, with most thalassemia sufferers dying before the age of 40. However, the latest advances in bone marrow transplantation significantly reduce both treatment time and cost, giving Gulf thalassemia patients and their families new hope, said a statement.

With thalassemia, we want to treat the underlying disease, not just the symptoms, and this approach requires bone marrow transplantation, said Dr Rabi Hanna, pediatric oncologist at US-based Cleveland Clinic.

Now, finding a matching bone marrow donor is much easier, as we only require a haplo-donor half-match, meaning every patient can find a donor (father, mother or half-sibling), as opposed to only 25 per cent, which has been the case for the last 25 years, added Dr Hanna. Bone marrow transplantation is the process by which a compatible donor, typically a matching sibling, has his or her stem cells transplanted into the thalassemia patients bloodstream via a tube called a central venous catheter. The stem cells travel through the blood into the bone marrow, thus enabling the growth of healthy, oxygen-carrying red blood cells.

The leading US hospital also believes it can work far more effectively with Gulf-based physicians to reduce the standard one-year treatment timeline for transplantation patients, as well as the associated costs and familial inconveniences associated with patient relocation. Some patients may only need to spend as few as three months in the US, it said.

The Dubai Thalassemia Center at the Dubai Health Authority will be one of several healthcare providers in the region to consider the new curative treatment option for its patients.

One such patient, 14-year-old UAE national was seen and treated by Dr Hanna at Cleveland Clinic last year and has benefited from a successful novel reduced intensity Haplo bone marrow transplant in November of 2016.

My life is now completely normal, and I expect to live into old age. I even have high energy levels, enabling me to experience activity for the first time in my life, said the patient.

I no longer require regular blood transfusions, and I can attend school without missing classes and other activities, she said. TradeArabia News Service

New 'cure' for thalassemia sufferers - Trade Arabia

Bone Marrow Stem Cells Comments Off on New ‘cure’ for thalassemia sufferers – Trade Arabia | May 7th, 2017

Last February, Timothy Ray Brown a.k.a. the Berlin patient celebrated his 10th birthday. Well, sort of. His 10th birthday actually refers to the 10th anniversary marking his recognition as the only person in the world to be cured of HIV, the virus that causes AIDS.

Browns incredible story began in 1995 when he was diagnosed with HIV. For over 10 years, he was able to stave off the disease by taking antiretroviral drugs. But disaster decided to strike again. Aside from HIV, it turned out that he had developed cancer as well, specifically, acute myeloid leukemia.

To fight off the cancer, Browns doctors decided to use chemotherapy and radiation to destroy his immune system, then use donated stem cells via a bone marrow transplant to rebuild it. It was supposed to be a standard treatment, but the doctors tweaked it a bit. The stem cell donor they chose was immune to HIV. Scientifically, this means that the donor had a gene mutation that caused him not to have CCR5 in his cells; CCR5 is the protein that allows HIV to get into a persons blood cells.

Brown received two bone marrow transplants, and the results were nothing short of a miracle he was cured of both HIV and cancer!

That extraordinary feat resulted in a common consensus that it was the transplant that saved Brown from his two lethal diseases. Based on new evidence, however, that conclusion might have to be re-evaluated. It might not have been the transplant that cured him. Rather, his immune systems reaction to the transplant that finally did the trick.

The immune reaction is known as graft-versus-host disease. Essentially, what happens is this: the donors immune cells attack the recipients cells. In Browns case, the donors cells attacked his immune cells (including the HIV contained in the cells). The result was the death of the HIV in his system.

At the IrsiCaixa AIDS Research Institute in Spain, six patients with HIV and cancer who received treatment similar with Browns now appear to be cleared of HIV.

Something to think about, though. Among the six patients, only one received the exact same treatment as Browns the bone marrow donor had the CCR5 gene mutation. Yet all six of them developed graft-versus-host disease.

Unless they stop taking their anti-HIV drugs, it cant be confirmed if they have been completely cleared of HIV. So far, though, all HIV tests on the six of them have been negative for 2 years. And that can certainly add support to the idea that its the graft-versus-host disease that kills HIV, not the transplant.

Still, if this does turn out to be accurate, it might not be such an appealing approach to use because its virtually a deliberate attempt to kill a patients immune cells which can easily turn fatal. Especially for patients who have the means to afford the expensive anti-HIV drugs, exposing ones self to further risk via transplantation is not really a logical option.

Although theres some consolation in the fact that at least there are anti-HIV drugs that can keep the disease at bay as long as you continue taking the drugs, its obviously far from being satisfactory given the fact that not everyone can afford such an expensive lifetime treatment. Which is why so much studying still needs to be done to better understand HIVs behavior and how this nasty virus can be eradicated. Lets hope science eventually leads us to a safer and more affordable cure.

Bone Marrow Stem Cells Comments Off on Vitamin A deficiency is detrimental to blood stem cells – Science Daily | May 7th, 2017

May 5, 2017

Lack of vitamin A in the body has a detrimental effect on the hematopoietic system in the bone marrow. The deficiency causes a loss of important blood stem cells, scientists from the German Cancer Research Center (DKFZ) and the Heidelberg Institute of Stem Cell Research and Experimental Medicine (HI-STEM) now report in the latest issue of the journal Cell. These findings will open up new prospects in cancer therapy.

Many specialized cells, such as in the skin, gut or blood, have a lifespan of only a few days. Therefore, steady replenishment of these cells is indispensable. They arise from so-called "adult" stem cells that divide continuously. In addition, there is a group of very special stem cells in the bone marrow that were first discovered in 2008 by a research team led by Andreas Trumpp, who is a division head at the DKFZ and director of HI-STEM. These cells remain in a kind of dormancy most of the time and only become active in an emergency such as bacterial or viral infections, heavy blood loss, or in the wake of chemotherapy. Once their work is done, the body sends its most potent stem cells back to sleep. The scientists assume that this protects them from dangerous mutations that may lead to leukemia.

The mechanisms that activate these special stem cells or make them go back to sleep after their work is done have remained elusive until now. The scientists have now identified retinoic acid, a vitamin A metabolite, as a crucial factor in this process. If this substance is absent, active stem cells are unable to return to a dormant state and mature into specialized blood cells instead. This means that they are lost as a reservoir. This was shown in studies with specially bred mice whose dormant stem cells are green fluorescent. "If we feed these mice on a vitamin A deficient diet for some time, this leads to a loss of the stem cells," said Nina Cabezas-Wallscheid, who is the first author of the publication. "Thus, we can prove for the first time that vitamin A has a direct impact on blood stem cells."

This finding not only enhances our understanding of the development of blood cells, it also sheds new light on prior studies that demonstrate that vitamin A deficiency impairs the immune system. "This shows how vitally important it is to have a sufficient intake of vitamin A from a balanced diet," Cabezas-Wallscheid emphasized. The body cannot produce its own vitamin A.

The scientists also have hopes for new prospects in cancer treatment. There is evidence that cancer cells, like healthy stem cells, also rest in a state of dormancy. When dormant, their metabolism is almost completely shut downand this makes them resistant to chemotherapy. "Once we understand in detail how vitamin A or retinoic acid, respectively, sends normal and malignant stem cells into dormancy, we can try to turn the tables," explained Trumpp. "If we could make cancer cells temporarily enter an active state, we could thus make them vulnerable to modern therapies."

In addition, in collaboration with colleagues from the European Bioinformatics Institute in Cambridge, the team performed genome-wide analyses of single cells and discovered that the transition from dormant to active stem cells and then on to progenitor cells is a continuous one and follows a different path for each individual cell. So far, scientists had assumed that specific cell types develop step by step in a defined pattern. This finding revolutionizes the previous concept of how cell differentiation in the body takes place.
