Histological appearance of MSC pellet cultures on day 28 after SB431542 treatment under chondrogenic conditions. No change in DMMB, ALP, collagen type II and collagen type X staining can be detected between chondrogenic control pellets (A, E, I, M) and pellets treated with low doses of SB431542 (B, C, F, G, J, K, N, O). High doses of SB431542 lead to a dedifferentiation of the cells shown by decreased DMMB staining (D) and collagen type II staining (L) (Scale bar=200 μm).
