Abstract (original English)

Human mesenchymal stem cells (hMSCs) possess broad prospects in pre-clinical research. In vitro amplification of hMSCs requires appropriate medium to reach the number of seed cells with clinical significance. However, the uncertainty of the heterologous components of the traditional fetal bovine serum (FBS) culture medium has great safety risks. Moreover, existing commercial hMSCs medium is very expensive, therefore a safer and more optimal hMSCs medium is urgently needed. Accordingly, we developed five components adipose-derived hMSCs (hADMSCs) medium without xenogenic components, named E5 SFM. which is mainly composed of knockout serum replacement (KSR), and additionally four components such as fibroblast growth factor and transferrin. Here, we mainly compared the E5 SFM with traditional FBS-containing medium and a commercial medium by surface markers testing, proliferation assay as well as osteogenic, adipogenic and chondrogenic differentiation assessment. We demonstrated that hADMSCs cultured in the E5 SFM showed similar morphological characteristics and immunophenotypes to those in other media. Notably, cell proliferative capability was similar to that in the commercial medium, but higher than that in the FBS-containing medium and other media. Additionally, their capabilities of adipogenic and osteogenic differentiation were significantly higher than those of other media.
