Comparison of HSPCs recovery after radiation injury in each group MSCs and HSPCs co-culture model. A Schematic diagram of MSC-HSPCs co-culture model and radiation injury recovery experimental; B Cell morphology images of MSC and HSPCs co-culture models in each group 1–9 days after radiation injury, fibrous adherent cells are MSCs, round suspended cells are hematopoietic stem/progenitor cells, scale bar is 100 μm; C–D Change curves of total hematopoietic cell count and cell viability after radiation injury in each group of co-culture model, DSUP vs. WT group, ***p < 0.001; DSUP vs. CON group, ^###p < 0.001, n = 3,Mean ± SEM, by Student’s t-test
