title: Effects of serum, fibroblast growth factor, and platelet-derived growth factor on explants of rat tail tendon: a morphological study.
abstract: Eighteen tail tendon fascicles were explanted from a 40-day postpartum rat and maintained in both serum-supplemented and serum-free Eagle's minimal essential medium for 2 weeks. Epitendon and paratendon connective tissues were excluded from these explants. Tendon fibroblasts maintained in serum-supplemented medium proliferated and synthesized collagen. Tendon fibroblasts explanted in serum-free medium remained viable but did not proliferate. Fibroblast growth factor and platelet-derived growth factor were shown to stimulate proliferation of mature tendon fibroblasts in serum-free medium.
