Abstract

Chondrocytes enzymatically dissociated from 13-day-old mouse embryo tibia grow in monolayer culture with a fibroblast-like phenotype and express high levels of type I collagen. Chondrogenesis can be induced by transferring the adherent cells in suspension culture and maintaining them in the constant presence of mouse embryo extract. Round shaping of the cells and formation of multicellular aggregates rapidly follow the passage in anchorage-independent conditions. Cell differentiation is evidenced by a marked decrease in the level of type I collagen and by the induction of type II collagen which accumulates when ascorbic acid is included in the culture medium. The addition of the vitamin also triggers the aggregated chondrocytes to organize their extracellular matrix giving rise to a structure closely resembling the in vivo developing cartilage.
