Abstract:
:Growth and differentiation factor 7(GDF7), also later called as bone morphogenetic protein (BMP)12, is a new member of the BMP superfamily, which induces formation of tendon-like tissue formation in the ectopic implantation experiments. We examined the effect of BMP12 on proliferation and expression of phenotype-related genes in rat osteoblastic osteosarcoma ROS17/2.8 cells. BMP12 treatment enhanced proliferation of ROS17/2.8 cells within 3 days and this effect was observed at least up to day 6 of the treatment. The cell number was increased by about 50% on day 3 and about two-fold by day 6. These effects were observed at the dose range between 40 and 1,000 ng/ml. Treatment with BMP12 also enhanced alkaline phosphatase activity by about 50% in ROS17/2.8 cells within 24 h of the treatment. The effect peaked at 48 h and was still observed at 72 h. The enhancing effect of BMP12 on alkaline phosphatase was observed similarly at the doses ranging from 40 to 1,000 ng/ml. These data indicate that BMP12 has positive effects on proliferation and phenotypic expression of ROS 17/2.8 cells.
