成体间充质干细胞(MSC)正在进一步研究其在干细胞治疗中的用途。然而,由于它们在成人组织中的数量非常低,因此需要体外扩增才能产生临床应用所需的 MSC 数量。由于人口老龄化的增加,肌肉骨骼疾病的患病率增加,对有效的细胞疗法的需求不断增加。本综述调查了捐献者的年龄和性别以及接种密度等因素如何影响 MSC 扩增。捐赠者的年龄和性别的研究结果参差不齐,而接种密度研究对众多 MSC 来源产生了一致的结果,有利于较低的接种密度。需要进一步的研究来降低感染风险、细胞培养物中细胞特征的丧失,并通过无论患者因素如何快速扩增 MSC 来使基于细胞的疗法更具成本效益。
Adult mesenchymal stem cells (MSCs) are being investigated further for their use in stem cell therapies. However, as they are found in very low numbers in adult tissue, expansion in vitro is required to produce desired MSC numbers for clinical application. The need for effective cell-based therapies is increasing due to a rise in the ageing population, increasing the prevalence of musculoskeletal disorders. This review investigates how factors, age and gender of donor, as well as seeding density can affect MSC expansion. Age and gender of donor have received mixed results from studies, whereas seeding density studies have produced consistent results for numerous MSC sources, favouring lower seeding densities. Further research is required to reduce the risk of infection, loss of cell characterisation in cell culture, and making cell-based therapies more cost effective through creating rapid expansion of MSCs regardless of patient factors.
