A positive effect of p21cip1/waf1 in the colony formation from murine myeloid progenitor cells as assessed by retroviral-mediated gene transfer.


p21cip1/waf1 is a cyclin dependent kinase inhibitor. We have previously reported stimulation of p21cip1/waf1 by steel factor and GM-CSF in a factor dependent cell line and of p21cip1/waf1 involvement in hematopoiesis in vivo in p21cip1/waf1 gene knockout (-/-) mice. To further assess a role for increased p21cip1/waf1 in hematopoietic progenitor cells, we… (More)
