人间充质干/基质细胞(humanmesenchymalstemstromalcells,hMSCs)由于其多向分化潜能和免疫调节作用而在再生医学领域引起了广泛的关注。虽然hMSC可以从不同的组织中获得,但临床应用中可用的细胞数量总是很低,因此需要体外扩增。目前大多数hMSC扩增方案都使用胎牛血清(FBS)作为富含营养的补充剂。然而,监管指南鼓励新的无异种替代品来定义更安全和标准化的hMSC扩增方案,以保留其内在的治疗潜力。由于hMSCs是贴壁细胞,因此贴壁表面和细胞粘附组分对其成功扩增也起着至关重要的作用。本文综述了无FBS培养基和表面/涂层的优点/缺点,避免使用动物血清,克服伦理问题,并以安全和可重复的方式提高hMSC的临床应用扩展。
Human mesenchymal stem/stromal cells (hMSCs) have generated great interest in regenerative medicine mainly due to their multidifferentiation potential and immunomodulatory role. Although hMSC can be obtained from different tissues, the number of available cells is always low for clinical applications, thus requiring in vitro expansion. Most of the current protocols for hMSC expansion make use of fetal bovine serum (FBS) as a nutrient-rich supplement. However, regulatory guidelines encourage novel xeno-free alternatives to define safer and standardized protocols for hMSC expansion that preserve their intrinsic therapeutic potential. Since hMSCs are adherent cells, the attachment surface and cell-adhesive components also play a crucial role on their successful expansion. This review focuses on the advantages/disadvantages of FBS-free media and surfaces/coatings that avoid the use of animal serum, overcoming ethical issues and improving the expansion of hMSC for clinical applications in a safe and reproducible way.
