Abstract

Mesenchymal stem/stromal cells (MSCs) show tremendous potential for regenerative medicine due to their self-renewal, multi-differentiation and immunomodulatory capabilities. Largely studies had indicated conventional tissue-derived MSCs have considerable limited expandability and donor variability which hinders further application. Induced pluripotent stem cell (iPSCs)-derived MSCs (iMSCs) have created exciting source for standardized cellular therapy. However, the cellular and molecular differences between iMSCs and the cognate tissue-derived MSCs remains poorly explored. In this study, we first successfully reprogrammed human umbilical cords-derived mesenchymal stem/stromal cells (UMSCs) into iPSCs by using the cocktails of mRNA. Subsequently, iPSCs were further differentiated into iMSCs in xeno-free induction medium. Then, iMSCs were compared with the donor matched UMSCs by assessing proliferative state, differentiation capability, immunomodulatory potential through immunohistochemical analysis, flow cytometric analysis, transcriptome sequencing analysis, and combine with coculture with immune cell population. The results showed that iMSCs exhibited high expression of MSCs positive-makers CD73, CD90, CD105 and lack expression of negative-maker cocktails CD34, CD45, CD11b, CD19, HLA-DR; also successfully differentiated into osteocytes, chondrocytes and adipocytes. Further, the iMSCs were similar with their parental UMSCs in cell proliferative state detected by the CCK-8 assay, and in cell rejuvenation state assessed by β-Galactosidase staining and telomerase activity related mRNA and protein analysis. However, iMSCs exhibited similarity to resident MSCs in Homeobox (Hox) genes expression profile and presented better neural differentiation potential by activation of related pathway. Moreover, iMSCs owned enhanced immunosuppression capacity through downregulation pools of pro-inflammatory factors, including , etc. and upregulation anti-inflammatory factors , etc. signals. In summary, our study provides an attractive cell source for basic research and offers fundamental biological insight of iMSCs-based therapy.

摘要

间充质干/基质细胞(MSCs)因其自我更新、多向分化和免疫调节能力,在再生医学领域展现出巨大潜力。大量研究表明,传统组织来源的MSCs扩增能力相当有限且存在供体差异,这阻碍了其进一步应用。诱导多能干细胞(iPSCs)来源的MSCs(iMSCs)为标准化细胞治疗提供了令人兴奋的细胞来源。然而,iMSCs与同源组织来源的MSCs之间的细胞和分子差异仍未得到充分探索。在本研究中,我们首先通过使用mRNA混合物成功地将人脐带间充质干/基质细胞(UMSCs)重编程为iPSCs。随后,iPSCs在无血清诱导培养基中进一步分化为iMSCs。然后,通过免疫组织化学分析、流式细胞术分析、转录组测序分析,并结合与免疫细胞群体共培养,对iMSCs与供体匹配的UMSCs进行增殖状态、分化能力、免疫调节潜力评估比较。结果显示,iMSCs高表达MSCs阳性标志物CD73、CD90、CD105,不表达阴性标志物混合物CD34、CD45、CD11b、CD19、HLA - DR;也成功分化为骨细胞、软骨细胞和脂肪细胞。此外,通过CCK - 8法检测,iMSCs在细胞增殖状态方面与其亲代UMSCs相似;通过β - 半乳糖苷酶染色以及端粒酶活性相关mRNA和蛋白质分析评估,iMSCs在细胞年轻化状态方面也与亲代UMSCs相似。然而,iMSCs在同源盒(Hox)基因表达谱方面与驻留MSCs相似,并通过相关途径的激活表现出更好的神经分化潜力。此外,iMSCs通过下调包括等促炎因子池以及上调抗炎因子等信号,拥有增强的免疫抑制能力。总之,我们的研究为基础研究提供了一种有吸引力的细胞来源,并为基于iMSCs的治疗提供了基本的生物学见解。
