Stress decreased CD31⁺/c‐Kit⁺ cells in BM and PB. A, Representative dot plots and quantitative data for the numbers of CD31⁺/c‐Kit⁺ (per 2×10⁴ cells) in BM and PB (n=6–7, Mann–Whitney U test). B, BM‐derived c‐Kit⁺ cells were subjected to proliferation and apoptotic assays using Ki67 antibody or TUNEL staining, respectively. Representative images and quantitative data show proliferative and apoptotic cells (n=5–7, Student t test). Data are mean±SE. *P<0.01 vs controls. Scale bar, 50 μm. BM indicates bone marrow; PB, peripheral blood; TUNEL, TdT‐mediated dUTP nick‐end labeling.
