Absence of amplification of MDM2 gene, a regulator of p53 function, in myelodysplastic syndromes.

abstract：:The blast cells of acute myeloblastic leukemia may be considered as a renewal population maintained by stem cells that are capable of both self-renewal and differentiation. Blast stem cells grow in culture usually when stimulated by growth factors normally active on myelopoietic cells. Two culture methods permit an ev...
