Abstract:BACKGROUND: Icariin has been shown to enhance bone formation.
OBJECTIVE: The present study aimed to investigate whether icariin also promotes bone fracture healing and its mechanisms.
METHODS: First, we isolated and cultured rat bone marrow stromal cells (rBMSCs) with icariincontaining各种浓度的血清(0%,2.5%,5%和10%)然后测量了碱性磷酸酶(ALP)活性以及核心结合因子,α1(CBFα1),骨形态发生蛋白-2(BMP-2)(BMP-2)和骨形态发生蛋白-4(BMP-4)的表达。其次,我们在大鼠中建立了一个骨折愈合模型,并进行了20天的肿瘤治疗。 Then, we detected bone biochemical markers (ELISA kits) in the serum, fracture healing (digital radiography, DR), and osteocalcin expression (immunohistochemistry).
RESULTS: Icariin treatment increased ALP activity and induced the expression of Cbfα1, RBMSC中的BMP-2和BMP-4以剂量依赖性方式。此外,伊卡林蛋白增加了骨钙素(OC)的血清水平,骨特异性碱性磷酸酶(BAP),I型胶原蛋白(NTX-1)的N末端端肽(NTX-1),I型I胶原蛋白(CTX-1)的C-末端端肽(CTX-1)和tartrate-nistrate-contrate-contrate-contrate-contrate-contrate-contrate-contrate-contrate-contrate-contrate-contrate-consistant-Acidant-Acid phassantastase phopphospasase 5b(tracspasase 5b)(易变)5B(易);在骨折部位促进骨钙素分泌;并加速骨折愈合。
结论: icariin可以促进骨形成标记的水平,加速骨折愈合,并激活Wnt1/β-catenin osteenin-osteenin-osteenin osteenic信号通路
