furthermore found that cell divisions of purified CD34+CD45RAi*CD71 ~ cells in vitro is associated with a predictable decrease (37 base pairs per division) in mean telomere length in the cultured progeny of the cells. Taken together, these observations strongly suggest that the proliferative potential of hematopoietic (stem) ceils is not unlimited and that loss of telomeric DNA during successive cell divisions contributes to the loss of this potential. From a practical point of view, these observations favor the use of relatively large numbers of adult hematopoietic cells for transplantation or the use of fetal or cord blood cells. 1.

## Abstract An increasing body of evidence has accumulated in recent years supporting the existence of neural stem cells in the adult gut. There are at least three groups that have obtained them using different methodologies and have described them in vitro. There is a growing amount of knowledge o
## Abstract Neural stem cells (NSCs) are multipotential progenitor cells that have selfβrenewal activities. A single NSC is capable of generating various kinds of cells within the central nervous system (CNS), including neurons, astrocytes, and oligodendrocytes. Because of these characteristics, th
