目的 明確萎縮性骨不連組織中表達(dá)上調(diào)的數(shù)種微小RNA（micro RNA，miRNA）與其相應(yīng)靶基因mRNA、蛋白在hBMSCs 成骨分化過程中的表達(dá)變化趨勢和生物學(xué)功能。 方法 取自體髂骨植骨手術(shù)患者的髂骨骨髓血，采用密度梯度離心法分離培養(yǎng)hBMSCs。取第4 代hBMSCs 以成骨誘導(dǎo)培養(yǎng)液誘導(dǎo)成骨分化，分別提取0、12 h，1、2、4、7、14 d 時(shí)的細(xì)胞總RNA 和蛋白，進(jìn)行miRNA 的實(shí)時(shí)定量PCR（quantitative real-time PCR，qRT-PCR）、相應(yīng)靶基因mRNA 的qRT-PCR 和蛋白Western blot 檢測。 結(jié)果 誘導(dǎo)hBMSCs 成骨分化時(shí)，成骨性靶基因堿性磷酸酶（alkaline phosphatase liver/bone/kidney，ALPL）、PDGF-α 多肽（PDGF-α polypeptide，PDGF-A）和BMP-2 的mRNA 和蛋白表達(dá)在多數(shù)時(shí)間點(diǎn)同對照（0 h）相比增加（BMP-2 在12 h 和1 d 時(shí)下降），1 ～ 7 d 變化最為顯著。不同時(shí)間點(diǎn)的miRNA、靶基因mRNA 和蛋白表達(dá)水平存在差異，其中hsa-miRNA-149 和hsa-miRNA-654-5p miRNA 含量的變化趨勢與各自靶基因ALPL 和BMP-2 的mRNA 及蛋白表達(dá)水平總體上成負(fù)相關(guān)（P  lt; 0.05），hsa-miRNA-221 與其靶基因PDGF-A 的變化趨勢無明顯負(fù)相關(guān)關(guān)系（P  gt; 0.05）。 結(jié)論 誘導(dǎo)hBMSCs 成骨分化過程中，hsa-miRNA-149 和hsa-miRNA-654-5p 對其相應(yīng)靶基因ALPL 和BMP-2 的mRNA 及蛋白存在密切調(diào)控關(guān)系。
