N normal phenotype
hematopoietic system
• purified GMPs from homozygous mice transfected with retroviral transduction of cre form only colonies composed of myeloblasts
• cultured CMPs form megakaryocyte/erythroid colonies as well as myeloblast colonies that appear to replace GM-related colonies that form when normal CMPs are cultured
