DIA-based quantitative proteomics was used to determine how donor pooling and 3D culture reshape sEV cargo composition, reduce batch-level heterogeneity, and establish conserved protein signatures across tissue sources. The dataset identifies manufacturing-responsive molecular programs related to mitophagy, immune communication, phagocytosis, membrane repair, wound healing, and mitochondrial metabolism. Foreskin-derived MSC-sEVs showed the strongest response to pooled-donor and 3D culture conditions, supporting their potential as a platform for engineered immuno-mitochondrial and reparative vesicle products.Sun Jul 05 00:00:00 GMT+01:00 2026PXD0806219606
