【摘要】：目的:探尋小鼠ADSCs的體外分離培養(yǎng)方法以及成骨誘導(dǎo)前后造血調(diào)控因子分子水平的表達(dá)情況。方法:采用酶消化法獲得脂肪來源的細(xì)胞,傳代培養(yǎng)至第三代,分別進(jìn)行成脂與成骨細(xì)胞誘導(dǎo),用實(shí)時熒光定量多聚酶鏈反應(yīng)(qRT-PCR)檢測成骨誘導(dǎo)前后的造血調(diào)控因子β-catenin、SDF-1、N-cadherin、SCF、MIP-1α和Jag 1,GM-CSF的表達(dá)。同時采用流式細(xì)胞儀測定ADSCs細(xì)胞表面標(biāo)志物CD29、CD34、CD106、CD49d的表達(dá)。結(jié)果:小鼠脂肪來源的細(xì)胞在體外培養(yǎng)過程中,呈梭形貼壁生長,可穩(wěn)定傳代;細(xì)胞表面標(biāo)志的流式細(xì)胞儀檢測:CD29表達(dá)率強(qiáng)陽性,CD34表達(dá)率較低,CD106、CD49d低表達(dá);進(jìn)行成脂細(xì)胞誘導(dǎo)后,油紅“O”染色呈陽性,成骨細(xì)胞誘導(dǎo)后,茜素紅染色和von Kossa染色均為陽性,表明其是ADSCs。通過qRT-PCR檢測多種造血調(diào)控因子相對表達(dá)量,發(fā)現(xiàn)β-catenin表達(dá)量最高,SDF-1和N-cadherin次之,其余各因子SCF、MIP-1α、Jag1、GM-CSF均為低表達(dá)。統(tǒng)計(jì)分析后,發(fā)現(xiàn)各因子在成骨誘導(dǎo)前后表達(dá)差異均無統(tǒng)計(jì)學(xué)意義。結(jié)論:本研究證實(shí),小鼠脂肪來源的細(xì)胞具有MSC特征就是ADSCs,其成骨誘導(dǎo)前后的造血調(diào)控因子均有不同程度的表達(dá),但差異無統(tǒng)計(jì)學(xué)意義。
[Abstract]:Aim: to investigate the isolation and culture of mouse ADSCs in vitro and the expression of hematopoietic regulatory factors before and after osteogenesis. Methods: the adipose derived cells were obtained by enzyme digestion and cultured to the third generation. The adipogenic cells and osteoblasts were induced respectively. The expression of hematopoietic regulatory factors 尾-catenin,SDF-1,N-cadherin,SCF,MIP-1 偽 and Jag 1 GM-CSF before and after osteogenesis was detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR). At the same time, flow cytometry was used to detect the expression of CD29,CD34,CD106,CD49d on the surface of ADSCs cells. Results: the murine adipose derived cells were fusiform adherent to the wall in vitro and could be subcultured stably. Flow cytometry showed that the expression rate of CD29 was strongly positive, the expression rate of CD34 was low, and the expression of CD106,CD49d was low. After adipoblast induction, oil red "O" staining was positive, and osteoblast induction, alizarin red staining and von Kossa staining were positive, indicating that it was ADSCs.. The relative expression of various hematopoietic regulatory factors was detected by qRT-PCR. It was found that the expression of 尾-catenin was the highest, followed by SDF-1 and N-cadherin, and the other factors SCF,MIP-1 偽 and Jag1,GM-CSF were all low expression. After statistical analysis, it was found that there was no significant difference in the expression of each factor before and after osteogenesis. Conclusion: this study confirmed that the expression of hematopoietic regulatory factors before and after osteogenesis induced by ADSCs, was the characteristic of MSC in adipose derived cells of mice, but the difference was not statistically significant.
