Serum‐free media for the production of human mesenchymal stromal cells: a review

The regenerative potential of mesenchymal stromal cells (MSC) holds great promise in using them for treatment of a wide range of debilitating diseases. Several types of culture media and systems have been used for large‐scale expansion of MSCs in vitro; however, the majority of them rely heavily on using foetal bovine serum (FBS)‐supplement for optimal cell proliferation. FBS‐based cultures pose the potential threat of spread of transmissible spongiform encephalopathy and bovine spongiform encephalopathy to MSCs and then to their recipients. A recent trend in cell culture is to change from serum‐use to serum‐free media (SFM). In this context, the current review focuses specifically on employment of various SFM for MSCs and discusses existences of various options with which to substitute FBS. In addition, we analyse MSC population growth kinetic patterns using various SFM for large‐scale production of MSCs.
