Membrane vesicles mediate pro-angiogenic activity of equine adipose-derived mesenchymal stromal cells

摘要

Multipotent mesenchymal stromal cells (MSCs) have attracted a great deal of interest, due to several distinctive features, including the ability to migrate to damaged tissue and to participate in tissue regeneration. There is increasing evidence that membrane vesicles (MVs), comprising exosomes and shedding vesicles, represent a key component, responsible for many of the paracrine effects of MSCs. The aim of the present study was to establish whether equine adipose-derived MSCs (E-AdMSCs) produce MVs that are capable of influencing angiogenesis, a key step in tissue regeneration.
