Quantitative proteomics analysis of different sources of hMSCs


ABSTRACT: Mesenchymal stem cells (MSCs) are an attractive therapeutic tool for tissue engineering and re-generative medicine due to their regenerative and trophic properties. The best-known and most widely used are bone marrow MSCs, but they are now being harvested and developed from a wide range of adult and perinatal tissues. MSCs from different sources are believed to have dif-ferent secretion potentials and production, which may influence their therapeutic effects. To prove it, we performed a quantitative proteomic analysis based on the TMT technique of MSCs from 3 different sources: wharton’s jelly (WJ), dental pulp (DP) and bone marrow (BM). Our analysis has focused on MSC biological properties of interest for tissue engineering. We identified a total of 611 human proteins differentially expressed. WJ-MSCs shown the greatest variation compared to the other sources. WJ produced more extra-cellular matrix (ECM) proteins and ECM-affiliated proteins and appeared to more able to modulate the inflammatory and immune response. BM-MSCs display enhanced differentiation and paracrine communication capabilities. DP-MSC appeared to promote exosome production. The results obtained confirm the existence of differences between WJ, DP and BM-MSC and the need to select the MSC origin according to the therapeutic objective sought.
