Stem Cells News and Research

RSS

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Scientists overcome obstacles to stem cell heart repair

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) at Imperial College London have overcome two significant obstacles on the road to harnessing stem cells to build patches for damaged hearts.

High-dose chemo and stem cell transplant shows little or no survival benefit for breast cancer

High-dose chemotherapy and autologous stem cell transplantation, the controversial, arduous, yet once-popular combination treatment that fell out of favor as a therapy for breast cancer, has proven not to be beneficial as an adjuvant therapy for women with node-positive disease, according to an expansive analysis conducted by researchers at The University of Texas M. D. Anderson Cancer Center.

Patients without advance care plans more likely to die

Researchers at the University of Nebraska Medical Center (UNMC) in Omaha and the Fred Hutchinson Cancer Research Center in Seattle found only half of patients undergoing stem cell transplantation had advance care plans - documents such as living wills, power of attorney for health care, or life-support instructions - and those without plans were three times more likely to die during or after surgery.

Mild chemo before stem cell transplant causes long-term remission of follicular lymphoma

Treating relapsed follicular lymphoma patients with a milder chemotherapy regimen before they receive a blood stem cell transplant from a donor resulted in long-term complete remission for 45 of 47 patients in a clinical trial, researchers at The University of Texas M. D. Anderson Cancer Center report at the 49th annual meeting of the American Society of Hematology.

Umbilical cord blood transplant may confer advantages over bone marrow transplant for kids with life-threatening metabolic disorders

Children born with inherited metabolic disorders that cause organ failure and early death can be treated successfully with umbilical cord blood transplants from unrelated donors and, in some cases go on to live for many years, according to a study led by Duke University Medical Center researchers.

Vaccine improves event-free survival for leukemia patients

Patients whose immune system responded to a peptide vaccine for leukemia enjoyed a median remission that was more than three times longer than non-responders, a team led by researchers at The University of Texas M. D. Anderson Cancer Center reports at the 49th Annual Meeting of the American Society of Hematology.
