Stem and progenitor cell death status. Live, early-apoptotic, late-apoptotic, and necrotic circulating hematopoietic stem and progenitor cells (CPC) as percentage of total analyzed CPC. Percentages did neither differ between cell isolation—by density gradient centrifugation (DGC) or red blood cell lysis (RBCL)—nor gating over lymphocytes or mononuclear cells. It is to note that live and early-apoptotic CPC make up almost 100% of analyzed CPC. There were only very few late-apoptotic CPC visible after DGC and a complete lack of necrotic CPC. Data are displayed as arithmetic mean and standard deviation. n = 6. Repeated-measures ANOVAs with Bonferroni post hoc comparisons were used for analysis. Significant differences are indicated as follows: non-significant, n.s
