Scientists pinpoint key proteins in blood stem cell replication

Summary:

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. Many types of human blood cancers involve a similar disruption in the expression of that same family of molecules.
