Impact of cell culture transition on adipose-derived mesenchymal stromal cells: Multi-omics analysis of small- vs large-scale production.

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
Mesenchymal stromal cells (MSCs) are being tested in numerous clinical trials, yet the limited progression of these trials to advanced stages indicates unresolved translational challenges. Expanding MSCs is a critical step in most therapeutic applications, and bioreactor-based culture offers large-scale production compared to monolayer cultures. Nevertheless, since MSCs sense their microenvironment, it is crucial to understand how these systems affect their properties. We expanded human adipose-derived mesenchymal stromal cells (AD-MSCs) from the same donors in both small- and large-scale platforms. Bulk-RNA sequencing (RNA-seq) and mass spectrometry analysis demonstrated that small-scale culture had a broader range of differentially expressed genes (DEGs) and proteins within immunomodulatory, cell migration, and cell adhesion pathways. In contrast, the large-scale culture showed a lower amount of DEGs and proteins associated mainly with extracellular matrix synthesis. Our findings demonstrate that expansion platforms significantly impact MSCs' properties, highlighting the need to optimize expansion conditions to obtain high cell yield without compromising MSCs' attributes.
