[Influence of stretch strain and pressure on expression of osteoblasts' FOS protein].
Uniaxial stretch strain and compressive pressure of 2 atm were applied to rat's osteoblasts, and then immunohistochemistrical staining was used to detect the expression of osteoblasts' c-fos gene. The experiment result indicated the osteoblasts' FOS proteins increased prominently, and the FOS proteins concentrated in nucleolus after having endured two different kinds of loadings. It is very important to prompt stress and strain in promoting osteoblast proliferation.
