Osteogenic markers found in undifferentiated BM-MSC- and WJ-MSC-secreted EVs. Number of proteins found in extracellular vesicles (EVs) isolated by size exclusion chromatography (n = 3 different cell lines for BM-MSC and WJ-MSC). The osteogenic markers differentially overrepresented in BM-MSC EV samples are indicated. Results were obtained by LC-MS/MS, two peptides restricted, FDR<5%
