Abstract (original English)

Mesenchymal stem cells (MSCs) are promising for cell-based therapies targeting a wide range of diseases. However, challenges in translating MSC-based therapies to clinical applications necessitate standardized protocols following Good Manufacturing Practices (GMP) guidelines. This study aimed at developing GMP-complained protocols for FPMSCs isolation and manipulation, necessary for translational research, by (1) optimize culture of MSCs derived from an infrapatellar fat pad (FPMSC) condition through animal-free media comparison and (2) establish feasibility of MSC isolation, manufacturing and storage under GMP-compliance (GMP-FPMSC). FPMSCs from three different patients were isolated following established protocols and the efficacy of two animal component-free media formulations in the culturing media were evaluated. The impact of different media formulations on cell proliferation, purity, and potency of MSCs was evaluated through doubling time, colony forming unit assay, and percentage of MSCs, respectively. Furthermore, the isolation and expansion of GMP-FPMSCs from four additional donors were optimized and characterized at each stage according to GMP requirements. Viability and sterility were checked using Trypan Blue and Bact/Alert, respectively, while purity and identity were confirmed using Endotoxin, Mycoplasma assays, and Flow Cytometry. The study also included stabili
