Expression data from human perivascular stem cell-derived extracellular vesicles (PSC-EVs) and PSCs

The vascular wall from diverse human organs is a source of mesenchymal progenitor cells that are able to induce skeletal repair, primarily by paracrine mechanisms. To investigate these paracrine mechanisms, FACS purified human perivascular stem cells (PSC) were observed to induce mitogenic, pro-migratory, and pro-osteogenic effects on osteoprogenitor cells while in non-contact co-culture, and did so via elaboration of extracellular vesicles (EVs). PSC-derived EVs shared mitogenic, pro-migratory, and pro-osteogenic properties of their parent cell. EVs represent a mixture of protein, lipid, and RNA that may affect cellular processes of the recipient cell. To begin to examine this, the RNA content of PSC-EVs was examined in comparison to the parent cell using total RNA sequencing. Overall design: 6 Total samples were analyzed: 3 x PSC total RNA and 3 x Extracellular Vesicle RNA biologic replicates
