the major changes that occurred in vitro were : an increase in the amount of lipid bodies in chondrocytes in the hypertrophic zone and in the bottom portion of the proliferative zone , failure of the chondrocytes in the bottom portion of the hypertrophic zone to increase in size , retention of intactness of the cell membrane of chondrocytes at the base of the hypertrophic zone , a decrease in the number of mitochondria in chondrocytes in the hypertrophic zone and in the middle and bottom portions of the proliferative zone , and a decrease in the number of holes in the cytoplasm of chondrocytes in the bottom one-half of the hypertrophic zone .
