Formation of cartilage in organ-cultured leg buds of chick embryo.
When the leg buds from chick embryos at stages 17-23 were cultured as organ cultures in F12 medium, which contained chick serum and an extract of chick embryos, leg cartilage structures developed that included pelvic girdle, femur, tibiofibula, and tarsometatarsus. The proportion of explants with definite distal elements increased when the leg buds from later embryos were used. Supplementation with chick serum was essential. These results suggest that the pattern of formation of limbs in chick embryos can be studied in organ culture.
