Dedifferentiated chondrocytes derived from 6-day-old chick embryo tibiae when transferred on agarose, revert to the chondrocytic phenotype and mature to hypertrophic, type X collagen-producing chondrocytes (Castagnola et al. (1986). J. Cell Biol. 102, 2310-2317). The continuous presence of 180 mM dimethyl sulfoxide (DMSO) during the culture specifically inhibited synthesis of type X collagen and accumulation of its mRNA. The synthesis of the cartilage-specific type II collagen and the level of its mRNA were essentially unchanged in treated and control untreated cells.
