To analyze the relationship between c-myc gene expression and chondrocyte proliferation and maturation during endochondral ossification, Day 18-19 chick embryo sterna were pulse-labeled with [3H]thymidine, and serial sections were processed for autoradiography and in situ hybridization. Proliferating chondrocytes, located in four distinct areas of the(More)
During skeletal development, chondrocytes go through several stages of differentiation. The last stage, chondrocyte hypertrophy, occurs in areas of endochondral ossification. Mature hypertrophic chondrocytes differ from immature chondrocytes in that they become postmitotic, increase their cellular volume up to eightfold, and synthesize a unique set of(More)
