Establishment and characterization of a new human megakaryoblastic cell line (SET-2) that spontaneously matures to megakaryocytes and produces platelet-like particles.

abstract：:We have previously shown that chronic lymphocytic leukemia (CLL) B cells secrete vascular endothelial growth factor (VEGF) in vitro, have constitutively active VEGF receptors R1 and R2, and respond to exogenous VEGF by specifically upregulating Mcl-1 and XIAP in association with decreased cell death. We found that epi...
