Abstract
Prostaglandins are known to be involved in bone metabolism as evidenced by the ability of PGE2 to induce bone resorption. It was, therefore, of interest to determine if there was an association of specific prostaglandin metabolites with the various stages of developing bone by utilizing the matrix-induced endochondral bone formation system. During mesenchymal cell proliferation a peak of endogenous thromboxane B2 was detected. In the subsequent stages of chondrogenesis and chondrolysis PGF2α was in high concentration, whereas during bone formation PGE2, 6-Keto-PGF1α and thromboxane B2 were elevated. These changes in the peak levels of the various prostaglandin metabolites may reflect differences in the cell populations and function associated with various stages of endochondral bone formation.
