【摘 要】 目的 探討人羊水來源c-kit+ 間充質(zhì)干細胞（c-kit+ human amniotic fluid-derived mesenchymal stem
cells，c-kit+ HAFMSCs）的生物學(xué)特征及心肌誘導(dǎo)分化能力。 方法 通過產(chǎn)前診斷或自愿引產(chǎn)獲取50 份孕中期羊水標
本，經(jīng)流式細胞儀分選c-kit+ HAFMSCs，MTT 法觀察細胞增殖情況，并通過流式細胞儀、細胞免疫化學(xué)染色觀察行細胞表
型鑒定。在體外經(jīng)成骨及成脂誘導(dǎo)分化，于誘導(dǎo)培養(yǎng)后21 d 采用von Kossa 染色觀察鈣沉積顆粒，油紅O 染色觀察脂滴
形成情況。實時熒光定量PCR 檢測細胞經(jīng)5 氮-2’ 脫氧胞苷心肌誘導(dǎo)前后，NKx2.5、Tbx5、GATA-4、α-MHC 4 種心肌特
異性基因表達情況。 結(jié)果 經(jīng)流式細胞儀分選，人孕中期羊水中c-kit+ HAFMSCs 含量約為貼壁細胞的3.07% ± 1.03%；
體外增殖迅速，表達MSCs 表面標志CD29、CD44、CD73、CD90、CD105，不表達造血干細胞表面標志CD34、CD45；表
達人類白細胞抗原（human leukocyte antigen，HLA）-ABC，不表達HLA-DR。細胞免疫化學(xué)染色示CD29、CD44、CD73、CD90、CD105、Oct-4 染色呈陽性，CD34、CD45 染色呈陰性。MTT 檢測示第5、10、15 代c-kit+ HAFMSCs 具有相似的生長曲線。成骨和成脂誘導(dǎo)培養(yǎng)后21 d，細胞內(nèi)有鈣鹽沉積和脂滴形成。實時熒光定量PCR 檢測示，心肌誘導(dǎo)后14 d， NKx2.5、Tbx5、GATA-4、α-MHC 4 種心肌特異性基因表達均較誘導(dǎo)前明顯增加，差異有統(tǒng)計學(xué)意義（P  lt; 0.05）。 結(jié)論 通過流式細胞儀分選的c-kit+ HAFMSCs 在體外可以誘導(dǎo)分化為心肌樣細胞，可能成為心肌再生性治療的種子細胞。
