[Abstract]  Microvesicle (MVs) are submicron-sized membranous vesicles that are either actively released from cells via secretory compartments or shed from cell surface membranes. MVs are generated by many cell types and serve as vehicles that transfer biological information (e.g., protein, mRNA, and miRNA) to distant cells, thereby affecting their gene expression, proliferation, differentiation, and function. Although their physiological functions are not clearly defined, recent studies have shown their therapeutic potential for tissue repair and regeneration. While MVs can be isolated readily from mesenchymal stem cells (MSCs) and other cell types from various sources, the yield of MVs under conventional culture condition in vitro is one of the limiting factors for both the in ... [摘要]  微囊泡(MV)是亚微米尺寸的膜泡囊,其通过分泌室从细胞中积极释放或从细胞表面膜脱落。 MV由许多细胞类型产生并且用作将生物信息(例如,蛋白质,mRNA和miRNA)转移到远端细胞的载体,从而影响其基因表达,增殖,分化和功能。 虽然他们的生理功能没有明确定义,但最近的研究已经显示出其组织修复和再生的治疗潜力。 虽然MV可以从间充质干细胞(MSC)和来自各种来源的其他细胞类型容易地分离,但在体外常规培养条件下MV的产量是限制因素之一, 功能研究以及体外分析分析。 在这里,我们提供了一个通过大鼠脑提取物预处理MSC增加微泡产量的方案。
【背景】通过直接重编程或利用间充质干细胞进行细胞替代治疗来产生神经干细胞或神经细胞是神经变性疾病的潜在选择(Adib等人,2015)。最近的研究已经证明,来自MSC的微泡代表了增强组织再生,例如神经元再生,免疫调节,脑损伤中的血管发生的其他细胞替代方法的新颖且安全的替代方案(Kim等人,2013) ; Porro等,,2015; Lee等人,2016)。对受损组织外源信号如何影响微泡数量和组成的了解甚少。 MSCs的功能分泌物的含量和数量可以根据微环境的显着变化(Qu等人,2007)。例如,已知缺血性脑提取物或缺氧诱导合成有益于组织再生过程的许多细胞因子和生长因子(Chen等,2007; Shin et ...
