重组人松弛素-3（Human Relaxin-3/rhRLX-3)

steopontin is a glycoprotein that was first identified in osteoblasts and is involved in bone remodeling，immune functions in fibroblasts，macrophages，and lymphocytes during inflammation and wound healing。 SPP1 binds tightly to hydroxyapatite。 SPP1 forms an integral part of the mineralized matrix。 SPP1 is vital to cell-matrix interaction。

Secreted Phosphoprotein-1 protects against cardiac ischemia-reperfusion injury via late preconditioning。 Expression of both Ostepontin and CD44 in hepatocellular carcinoma is linked with advanced tumor stage and contributes to prognosis information。 SPP1 is the most over-expressed gene in intrahepatic cholangiocarcinoma。 Secreted Phosphoprotein-1 overexpression is related with interstitial lung diseases。
