a comparative study of type x collagen expression , chondrocyte morphology , and the expression of two genes controlling chondrocyte morphology ( beta-actin and fibronectin ) was carried out on chondrocytes derived from a tissue that remains as permanent hyaline cartilage in vivo ( embryonic chicken caudal sterna ) , from a tissue that undergoes endochondral replacement ( embryonic chicken ventral vertebrae ) and caudal sternal chondrocytes treated with 1,25 ( oh ) 2d3 .
