Abstract (original English)

The development of robust and scalable culture systems is essential for the clinical-scale production of human umbilical cord (UC)-derived mesenchymal stem/stromal cells (MSCs) (UC-MSCs). While various basal and serum-free media are commercially available, systematic comparisons of their efficacy in supporting the expansion and functional properties of UC-MSCs remain limited. In this study, we conducted a comprehensive evaluation of multiple culture systems, including basal media (α-MEM, DMEM, and DMEM/F12) supplemented with human platelet lysate (HPL), and commercial serum-free media (Corning MSC Xeno-Free SFM, NutriStem XF Medium, Prime-XV MSC Expansion XSFM), for their ability to sustain UC-MSCs proliferation, maintain phenotypic properties, and support functional potency. The results demonstrated that all basal media supported cell growth, with α-MEM (Gibco) and DMEM/F12 showing superior performance over DMEM. Among serum-free formulations, Prime-XV with 2% HPL yielded the highest primary culture output and the shortest population doubling (PD) time (PDT) during passaging. Notably, cells expanded in commercial serum-free media exhibited reduced diameter and higher uniformity. Functional analyses revealed that NutriStem XF Medium supplemented with 2% HPL elicited the strongest immunomodulatory effects in mixed lymphocyte reactions (MLRs). Furthermore, all media maintained tr
