摘要 应力环境可调节骨组织的生长、吸收和重建。在细胞水平上,机械刺激可以影响成骨细胞的生理活性,如增殖、碱性磷酸酶活性、骨钙素合成等。力转导是将生物物理力转化为细胞的生化响应的过程,它是许多生理功能的基础,早期响应基因(c- fos,c- jun) ,第二信使系统(Ca2 + ,NO,c AMP) 。 The stress environment regulates the factors of growth, resorption and remolding in bone tissue. Mechanical stimulation at cell physical level affects the physiological activity of osteoblasts, including proliferation, ALP activity and osteocalcin production. Mechanotransduction is a procedure which transduces the biophysical force into biochemical responses. It is also the basis of many physiological functions. The early response genes (c-los, c-jun), the second message systems(Ca^2+ , NO, cAMP)and the mechano-sensitive cation channel are involved in the mechanotransduction course when osteoblasts respond to the mechanical stimulation.
