Repair-induced DNA strand breaks in hematopoietic cells after treatment with melphalan or cisplatin.

CD34⁺ and CD34^- cells from CB were exposed ex vivo to melphalan (A) or cisplatin (B) as in Figure 5. Cell aliquots were taken at different time points during or after treatment and comet analysis was performed as described in Figure 3 and in “Materials and methods.”
