A research team led by Nancy Speck, PhD, Professor of Cell and Developmental Biology at the University of Pennsylvania School of Medicine, has identified the location and developmental timeline in which a majority of bone marrow stem cells form in the mouse embryo.

Taking blood stem cells collected from an umbilical cord into the lab and expanding their number before transplanting them to replace a patient's blood supply is as safe as a standard cord blood transplant, researchers reported today at the 50th Annual Meeting of the American Society of Hematology.

Investigators from Massachusetts General Hospital (MGH) have found a subpopulation of hematopoietic stem cells, the source of all blood and immune system cells, that reproduce much more slowly than previously anticipated.

Stem cell researchers at UCLA have proven definitively that blood stem cells are made during mid-gestational embryonic development by endothelial cells, the cells that line the inside of blood vessels.

A family of cancer-fighting molecules helps blood stem cells in mice decide when and how to divide, say researchers at the Stanford University School of Medicine. Blocking the molecules' function spurs the normally resting cells to begin proliferating strangely - making too much of one kind of cell and not enough of another.

New Technology Enhances and Expands “Homing”and Therapeutic Potential of Cord Blood Stem Cells in Bone Marrow Transplants

Researchers at UT Southwestern Medical Center have for the first time used drug-treated blood stem cells to repair heart damage in an animal model, results that might point to methods for healing injuries from heart attacks or disease.

Solving a long-standing biological mystery, UCLA stem cell researchers have discovered that blood stem cells, the cells that later differentiate into all the cells in the blood supply, originate and are nurtured in the placenta.
