What is the best immunocytochemical marker for endogenous stem cells?

Endogenous populations of stem cells are proving to be highly relevant to the treatment of degenerative disease and to the initiation of cancer. It is crucial, therefore, to know how many of these cells exist in tissues and how their numbers are manipulated by disease and treatments. Markers for stem cells are constantly being discovered, and many are proving of great use. However, different markers do not always recognize the exact same populations of cells. Therefore, the confusion of the incidence of endogenous stem cells persists. The discrepancy between the recognition potential of different markers can be…
