Endothelial cell (EC) damage or dysfunction serves as the initial event in the pathogenesis of various cardiovascular diseases. Progenitor cells have been postulated to be able to differentiate into ECs, facilitate endothelial regeneration, and alleviate vascular pathological remodeling. However, the precise cellular origins and underlying mechanisms remain elusive.

Similar to other vascular diseases, stenosis of vein grafts is caused by several cell lines; however, the sources of these cells remain unclear. The objective of this study was to investigate the cellular sources that reshape vein grafts.

Sca1 stem/progenitor cells (SPCs) can generate de novo smooth muscle cells after severe vascular injury during vessel repair and regeneration. However, the underlying mechanisms have not been conclusively determined.

To investigate cells that are involved in disease development and tissue repair, various technologies have been introduced. Among these technologies, lineage tracing is a powerful tool to track the fate of cells in vivo, providing deep insights into cellular behavior and plasticity.

The main purpose of this study was to reveal the role and related molecular mechanism of microRNA-30c-5p (miR-30c-5p) in VSMC differentiation from adventitial progenitor cells expressing stem cell antigen-1(Sca-1).
Methods: In this study, we detected the expression of miR-30c-5p in human normal peripheral arteries and atherosclerotic arteries.
