摘要:

骨髓间充质干细胞(bone mesenchymal stem cells,BMSC)是一种增殖能力强、具有多向分化潜能的干细胞,广泛应用于临床及基础研究。近年来利用BMSC治疗多种临床难治性疾病成为研究热点,尤其是骨科相关疾病的治疗。目前骨缺损、股骨头坏死、软骨损伤、脊髓损伤和椎间盘退变等疾病临床尚无有效的治疗方法。未来,随着研究的深入,BMSC可能成为治疗骨科疾病的有效方式。BMSC定向分化为成骨细胞在骨科疾病治疗中发挥着重要作用。BMSC定向分化受到多种信号通路的影响,包括RANKL/RANK/OPG信号通路、Wnt信号通路、MAPK信号通路和PI3K/Akt信号通路等,但目前普遍认为PI3K/Akt信号通路是影响BMSC成骨分化的关键信号通路。近年来PI3K/Akt信号通路调控干细胞成骨分化成为研究热点,但未见调控PI3K/Akt信号通路成骨相关影响因素的报道,文章就PI3K/Akt信号通路及相关因素作一综述。
