Progenitor cells were isolated from six young adult horses, expanded in monolayers with FGF-2, and cultured with autogenous acellular pulverized tendon and IGF-I for seven days.

In the cell: pulverized tendon cultures, cell viability, expression of collagen types I and II, and cartilage oligomeric matrix protein (COMP) mRNAs, collagen and glycosaminoglycans (GAG) syntheses were assessed. Tendon-derived cells proliferated significantly more rapidly in the initial monolayer expansion cultures in comparison to bone marrow-derived cells.
