Human mesenchymal stem cells (hMSC) are becoming increasingly popular in tissue engineering. They are the most frequently used stem cell source for clinical applications due to their high potential to differentiate into several lineages. Cartilage is known for its low capacity for self-maintenance and currently there are no efficient methods to improve cartilage repair. Chondrogenic differentiation of hMSC isolated from different tissues is widely employed due to a high clinical demand for the improvement of cartilage regeneration. Calcium channels that are regulated by physical stimuli seem to play a pivotal role in chondrogenic differentiation of MSCs. These channels increase intracellular calcium concentration, which leads to the initiation of the relevant cellular processes that are required for differentiation. This review will focus on the impact of different physical stimuli, including electrical, electromagnetic/magnetic and mechanical on various calcium channels and calcium signaling mechanisms during chondrogenic differentiation of hMSC.
人骨髓间充质干细胞(hMSC)在组织工程中越来越受欢迎。由于其向多个谱系分化的巨大潜力,它们是临床应用中最常使用的干细胞来源。软骨的自我维持能力较低,目前尚无有效的方法来改善软骨修复。由于临床上对改善软骨再生的需求很高,因此广泛采用分离自不同组织的 hMSC 的软骨分化。受物理刺激调节的钙通道似乎在 MSC 的软骨分化中起着关键作用。这些通道增加细胞内钙浓度,从而启动分化所需的相关细胞过程。本综述将重点介绍不同物理刺激(包括电、电磁/磁场和机械刺激)对 hMSC 软骨分化过程中各种钙通道和钙信号机制的影响。
