Study on the Dynamic Biological Characteristics of Sca-1⁺ Hematopoietic Stem and Progenitor Cell Senescence

Figure 4

Distribution of cell cycle of Sca-1⁺ HSPCs (%, , ). Group A: 3-4-week-old mice, 13–16 g in body weight. Group B: 8-9-week-old mice, 20–25 g in body weight. Group C: 6-month-old mice, 35–40 g in body weight. Group D: 12-month-old mice, 39–43 g in body weight. Group E: 18-month-old mice, 37–45 g in body weight. (a–k) represent a significant difference of these columns ().
