Co-culture of HPCs with Ir-MSCs. Flow cytometric analysis showing the generation of hematopoietic cells from HPCs after 10 days of co-culture with lot A (a, b) and lot B (c, d) of BM-MSCs that were exposed to (white bars) or not exposed to (black bars) 0.1 Gy γ-radiation. The numbers of CD45⁺ cells, CD34⁺ cells, CD34⁺CD38⁻ cells, and CD34⁺CD38⁺ cells are shown in (a, c). Data are mean values ± SD. n = 5 per group. *, p < 0.05. Representative dot plots of CD34 versus CD38 expression are shown in (b, d). Numbers in each box indicate the percentage of cells
