  Mesenchymal stem cells (MSCs) have therapeutic potential in various diseases, including myocardial infarction. Recently, the importance of the therapeutic effects of secreted factors from MSCs is increasing, but their identification has not progressed. In this study, we uncover the secreted protein profiles of MSCs derived from bone marrow, adipose tissue and dental pulp. Shotgun proteome analysis of conditioned MSC media by mass spectrometry identified 1533 proteins totally and 124 secreted proteins commonly produced among all three MSCs. The commonly secreted factors include already well-known factors whose functions are linked to MSCs’ biological effects, such as CTGF, SERPINE1, TGFB1, DKK3 and MYDGF, and also include newly identified factors whose roles are not well investigated, for example AIMP1, CLEC11A, GAS6, HDGF, INHBA, and PCSK5.
