Adipogenic and osteogenic differentiation of three different lots of Ir-MSCs. (a–c) Quantitative measurement of the adipogenic differentiation of three different lots of BM-MSCs (lots B, C, and D) that were exposed to (white bars) or not exposed to (black bars) 0.1 Gy γ-radiation, as assessed by Oil Red O staining. (d–f) Quantitative measurement of the osteogenic differentiation of three different lots of BM-MSCs (lots B, C, and D) that were exposed to (white bars) or not exposed to (black bars) 0.1 Gy γ-radiation, as assessed by Alizarin Red S staining. Lot E of BM-MSCs was unavailable for this analysis due to an inadequate number of cells. Data are mean values ± SD. n = 4 per group (a, d) or n = 3 per group (b, c, e, f). *, p < 0.05
