Objective: Development of cell therapy and advanced therapy medicinal products depends on in vitro expansion of human cells in fetal bovine serum (FBS) supplemented media. Human-derived supplements, such as human serum (huS) and human platelet lysate (hPL), represent suitable alternatives to FBS. Various studies demonstrated that the use of these human alternatives result in comparable or even improved proliferation and expansion ratios. Methods: Within this study three human supplement alternatives, huS, hPL P (plasma containing hPL) and hPL N (plasma replaced by saline), were compared by 2D gel electrophoresis, an important tool in proteomic analysis. 2D gel electrophoresis allows the determination of the protein number and the detection of protein changes (decreasing/increasing concentration). Results and Conclusion: The comparison of huS, hPL P , and hPL N gels resulted in clearly visible differences in protein pattern, protein number and concentration, particularly when comparing huS with hPL and hPL P with hPL N .
