Optimization of Culture Media for Human Umbilical Cord-Derived Mesenchymal Stem Cell Production.
Article in Stem cells international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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 trilineage differentiation capacity and satisfied International Society for Cellular Therapy (ISCT) phenotypic criteria. Critically, no tumorigenic potential was detected in vitro or in vivo. Large-scale manufacturing using the selected medium (NutriStem XF + 2% HPL) confirmed consistent expansion kinetics, high viability, stable marker expression, and functional potency across seven production batches. This study provides a rigorous and clinically relevant framework for selecting culture media that ensure both scalability and functional integrity of UC-MSCs, highlighting the promise of serum-free systems for therapeutic manufacturing.
