[Collagen synthesis by osteoblasts in the maxilla in rats during the embryonic period]

Under study was the intensity of the collagen synthesis by osteoblasts of the primordium of the rat's maxilla at different terms of embryogenesis. Autoradiographic method revealed that the greatest part of incorporated glycin was used for construction of collagenous molecules, and the least part--for the synthesis of other cytoplasmic proteins of osteoblast. Different intensity of the synthesis of de novo collagen was established at different stages of embryogenesis. The most intensive synthesis of collagen was found to begin from the 18th day of the maxillary bone primordium development.
