Abstract:
Rat's osteoblasts cultured in vitro were stimulated by recombinant bovine basic fibroblast growth factor(rb-bFGF). After 1-2 days, the osteoblast grew long protuberance, the numbers of osteoblasts were greater than the control groups', the vitality of osteoblasts was better than that of control groups. After 1 hour, the expression of c-fos in osteoblast increased when compared with that in the control group. After the osteoblasts having been stimulated for 1-2 days, the expression of c-fos increased more conspicuously. These results show that bFGF can boost the osteoblast to grow and proliferate and can enhance the expression of c-fos gene. The increase of c-fos gene's expression may be an important step in the signal transformation process of all kinds of stimulation boosting osteoblast to proliferate.

Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
