So the recent discovery by a Harvard Stem Cell Institute team that a family of well-known transcription factors plays a major role in regulating the life span and longevity of hematopoietic, or blood, stem cells is of particular note. Transcription factors are proteins that participate in the synthesis of RNA using a DNA template."}
