Radical Stem Cell Transplant for Acute Renal Failure

Saturday, October 12th, 2013

AUSTRALIAN rock legend Jim Keays has narrowly survived acute renal failure after a radical stem cell transplant he hopes will save his life.

Keays was diagnosed with multiple myeloma – a cancer of the blood’s plasma cells – six years ago and has been battling the disease since.

Myeloma often attacks the kidneys and Keays had chemotherapy and was put on dialysis after seeing his kidney function drop to 5 per cent.

Early this year he had a transplant using stem cells harvested from his own blood.

Then in radical, and still experimental, surgery, he recently received stem cells from an unknown donor – a man who does not even share Keays’ blood group.

“There is a global register of stem cells donors, and the doctors told me they had found a reasonable match on it,” the former Master’s Apprentices’ frontman explained.

All Keays, who turned 67 last month, knows of the donor is that he is 28 years old and from New Jersey.

When doctors explained the treatment Keays was told it was his “last roll of the dice”.

“The alternative was to die,” said Keays.

The Alfred flew a staff member to America to pick up the donated stem cells while Keays was given radiation therapy to subdue his body’s natural defence against foreign tissue.

“They operated on me nine weeks ago after zapping my immune system,” he said. “It allowed (the donor) stem cells to come in unchallenged.”

It seemed to go well but, as Keays was warned it might, graft-versus-host disease developed – a regular complication from such procedures.

“They warned me that it was still experimental and that there would be drawbacks.”

Not only is the donor not Keays’ blood type, the singer will now “inherit” the donor’s blood group and immune system.

Doctors have kept Keays alive in a complex balancing act involving a mix of sometimes debilitating medications.

“They tweak it on a daily basis,” he explained.

Keays’ kidneys failed in August and he had to call his daughter along with his musical offsider, Russell Morris, to carry him out of the house and on to hospital.

“It’s the third time I’ve been close to death, but now they say I am tracking really well,” he said.

“The donor cells appears to have imbedded themselves properly. I should be virtually free of the cancer.”

Keays has been a fixture on the Australian music scene for more than 45 years after bursting out of Adelaide with the Masters in 1966.

The band’s hits included Undecided, Elevator Driver, 5.10 Man, Turn Up Your Radio and Because I Love You.

For 12 years he performed as part of Cotton Keays Morris until cancer claimed Darryl Cotton last year.

Myeloma is incurable, but Keays has been told it is now almost undetectable and that he no longer requires medication.

He is deeply indebted to the specialists at The Alfred Hospital who are among the foremost experts in his disease in the world. And Keays wants to encourage more blood donations. “Give blood, donate stem cells, be an organ donor,” he said.

Keays, who hasn’t worked in nine months, is looking at hooking up with Morris for some performances later in the year.

“Russell has waited for me. I’ll be able to live a normal life again.

“There’s a tunnel. But I’ve spotted a light.”

New Hearts To Be Grown From Stem Cells

Wednesday, October 2nd, 2013

By Ronda Wendler, Texas Medical Center News 

Building natural organs from stem cells is the way forward in regenerative medicine.

Building natural organs from stem cells is the way forward in regenerative medicine.

The Texas Heart Institute and the veterinary medicine college at Texas A&M University will share a $3 million award from the state of Texas’ Emerging Technology Fund to create the Center for Cell and Organ Biotechnology.

“This center will play a key role in securing Texas’ very critical emerging role in biotechnology,” Gov. Rick Perry said at a Press Conference at the Heart Institute. “The sky is truly the limit for what this center will be able to accomplish.”

The new collaboration will focus on cell therapies and regenerative medicine, including building natural organs from stem cells.

Doris Taylor, Ph.D., who in 2008 created a beating rat heart at the University of Minnesota, was recruited to the Texas Heart Institute last year and will head the new center.

“Dr. Taylor is certainly one of the stars in the adult human stem cell field, and we feel extremely fortunate to have her,” said James Willerson, M.D., the Texas Heart Institute’s president and medical director.

Taylor is the developer of a technique known as decellularization, which involves stripping cells from an animal heart, leaving only a shell or scaffold of the heart in place, then infusing the scaffold with human stem cells to grow a new human heart.

At the Heart Institute, Taylor has created human heart models that are currently functioning at one-fourth capacity. She hopes to engineer a heart that functions at close to 100 percent capacity by 2015. The goal is to test such bioengineered hearts in clinical trials, probably in less than 10 years, she said, and eventually offer a solution to patients waiting for donor hearts, which are always in short supply.

Other scientists around the world are striving to do the same, and Texas Heart Institute founder Denton Cooley, M.D., said during the press conference that successful culmination of the institute’s efforts to engineer a human heart would be a fitting continuation of the heart institute’s legacy.

The decellularization approach is also being tried with other organs, Taylor said, including livers, kidneys and lungs.

Texas A&M’s College of Veterinary Medicine and Biomedical Sciences will contribute animal disease models to be used in cell therapy trials, as well as bioengineers who will build scaffolding upon which heart cells will grow. and experts in anatomy, physiology and stem cell science.

Scientists from the Heart Institute and Veterinary College will collaborate not only to grow new organs, but also to detect diseases earlier and to devise new cell and gene therapies to help prevent and treat diseases and injuries.

Texas A&M has more than 20,000 veterinary cases a year of animals with disease, and therefore will be invaluable in providing animals that can contribute to and benefit from this research, Taylor said.

Veterinarians and Heart Institute scientists will collaborate in other ways as well, she said. For example, racehorses with tendonitis are already being treated with stem cell therapy, and lessons learned could help human athletes. Doberman Pinschers routinely get heart disease and could benefit from the regenerative medicine efforts underway at the heart institute.

“It was clear from the beginning that this partnership was special,” said Eleanor Green, D.V.M., dean of A&M’s College of Veterinary Medicine and Biomedical Sciences. “We know that the health of animals and people is inextricably linked, and this unique center will advance both human and animal health.”

The state of Texas’ Emerging Technology Fund that funds the new center is a technology investment fund created at the urging of Gov. Rick Perry to give Texas an advantage in developing and commercializing emerging technologies. Launched in 2005, the fund has given out more than $200 million to startup companies and educational institutions.

The Texas Heart Institute’s next step, Taylor said, is to hire a technology transfer expert who will help form spin-off companies and commercialize its inventions.
