Human mesenchymal stem cells (hMSC) hold great promise as tools in cell therapy. Since hMSCs are rare in adult tissues, the isolated cells must be expanded in-vitro to generate sufficient cells number for clinical use.
The use of serum-free (SF), xeno-free (XF) culture system is an advantage in order to minimize the health risk of using xenogeneic compounds, and to limit the immunological reactions in-vivo. Under SF, XF culture condition, a coating step is usually required to enable cells attachment, spreading and proliferation in-vitro.
The coating procedure is an obstacle step for scale up towards cells therapy. Thus, having an optimal coating- free culture platform may provide efficient, user-friendly and economical hMSC manufacturing process.
In the present study, different combinations of treated plastic ware (uncoated) and SF, XF media were evaluated.
Results show that MSC NutriStem® XF (BI) together with Corning® CellBIND® (uncoated culture ware) is a superior platform for the expansion and proliferation of hMSC from a variety of sources.
