Radioprotective effect of vitamin D on bone marrow stroma1 cells (BMSCs) was studied. Mice were administrated subcutaneously with a daily dosage of 1,25 dihydrxyvitamin D for three days from 48h prior to 6.0Gy gamma-irradiation until they were sacrificed. The number of CFU-F, the apoptosis rate of bone marrow stromal cell, and the expressions of caspase-3 in BMSC were detected. The number of CFU-F significantly decreased after irradiation and vitamin D administration preserved the number of CFU-F in irradiated mice at same level as control. The apoptosis rate and relative level of caspase-3 in BMSC were significantly increased after irradiation and vitamin D administration ameliorated this effect. These data suggest that vitamin D can protect BMSC from apoptosis induced by irradiation.
