Large Extracellular Vesicles from Induced Pluripotent Stem Cell-marrow Stem Cells Enhance Limb Angiogenesis Via ERK/MAPK
Overview
Affiliations
This study aims to investigate the effects of large extracellular vesicles (EVs) induced by pluripotent stem cell-derived mesenchymal stem cells on lower limb ischemic disease and explore its potential mechanisms. The pathology of muscles was accessed by H&E staining and immunofluorescence staining. , we conducted wound-healing assay, tube formation assay, RT qPCR, ELISA, RNA sequencing and proteomic analysis. iMSCs-lEVs alleviated the injury of ischemic lower limb and promoted the recovery of lower limb function. , iMSCs-lEVs promoted the proliferation, migration, and angiogenesis of HMEC-1 cells by regulating the ERK/MAPK signing pathway. This study demonstrated that iMSCs-lEVs promoted endothelial cell angiogenesis via the ERK/MAPK signaling pathway, thereby improving function after lower limb ischemic injury.
