Abstract (original English)
Mesenchymal stromal cells (MSCs) are promising candidates for innovative cell therapeutic applications. For clinical scale manufacturing regulatory agencies recommend to replace fetal bovine serum (FBS) commonly used in MSC expansion media as soon as equivalent alternative supplements are available. We already demonstrated that pooled blood group AB human serum (HS) and thrombin-activated platelet releasate plasma (tPRP) support the expansion of multipotent adipose tissue-derived MSCs (ASCs). Slight differences in size, growth pattern and adhesion prompted us to investigate the level of equivalence by compiling the transcriptional profiles of ASCs cultivated in these supplements. A whole genome gene expression analysis was performed and data verified by polymerase chain reaction and protein analyses. Microarray-based screening of 34,039 genes revealed 102 genes differentially expressed in ASCs cultured with FBS compared to HS or tPRP supplements. A significantly higher expression in FBS cultures was found for 90 genes (fold change ≥2). Only 12 of the 102 genes showed a lower expression in FBS compared to HS or tPRP cultures (fold change ≤0.5). Differences between cells cultivated in HS and tPRP were hardly evident. Supporting previous observations of reduced adhesion of cells cultivated in the human alternatives we detected a number of adhesion and extracellular matrix-associat
