心脏特细胞 (CT) 移植对心肌梗死 (MI) 的中期影响以及参与 CT 移植有益效果的细胞机制尚不清楚。在本研究中,我们发现 CT 移植能够在 MI 后 14 周显着减小梗塞面积并改善心功能。已证实CT移植对心肌产生保护作用,并且这种保护作用至少维持14周。这种对 MI 有益作用背后的细胞机制部分归因于心脏血管生成的增加、CT 网络重建的改善和心肌纤维化的减少。这些综合作用减少了梗塞面积,改善了左心室的重建并增强了心肌梗塞时的心肌功能。我们的研究结果表明,CT 可被视为一种潜在的治疗用途细胞来源,可单独使用或与干细胞联合使用,以改善 MI 后的心脏修复和功能。
The midterm effects of cardiac telocytes (CTs) transplantation on myocardial infarction (MI) and the cellular mechanisms involved in the beneficial effects of CTs transplantation are not understood. In the present study, we have revealed that transplantation of CTs was able to significantly decrease the infarct size and improved cardiac function 14 weeks after MI. It has established that CT transplantation exerted a protective effect on the myocardium and this was maintained for at least 14 weeks. The cellular mechanism behind this beneficial effect on MI was partially attributed to increased cardiac angiogenesis, improved reconstruction of the CT network and decreased myocardial fibrosis. These combined effects decreased the infarct size, improved the reconstruction of the LV and enhanced myocardial function in MI. Our findings suggest that CTs could be considered as a potential cell source for therapeutic use to improve cardiac repair and function following MI, used either alone or in tandem with stem cells.
