Arsenic Primes Human Bone Marrow CD34+ Cells for Erythroid Differentiation

Figure 1

Proliferation and ATO-induced cytotoxicity of BM CD34+ cells. (a) Comparison of cell proliferation when cultured in StemPro-34 medium without and with added cytokines. Viable cells were identified by trypan blue exclusion. Data are mean from two experiments. (b) Effects of ATO at different concentrations on cell viability assessed by flow cytometry. Cells were treated with ATO for 7 days in StemPro-34 ().
