Unlocking the Potential: Investigating the Influence of Cellular Fitness on Adipose-Derived Mesenchymal Stem Cells in Regenerative Medicine.

Unlocking the Potential: Investigating the Influence of Cellular Fitness on Adipose-Derived Mesenchymal Stem Cells in Regenerative Medicine Adipose-derived mesenchymal stem cells (MSCs) hold considerable promise in regenerative medicine, but understanding the impact of individual cellular fitness on their functionality is a crucial research area. This study systematically examines this influence through a multi-phase approach. Initially, MSCs from nine human donors were assessed using the MTS assay for viability, the colony-forming unit (CFU) assay for clonogenic potential, and population doubling time (PDT) calculation for proliferative capacity. Three distinct cellular fitness groups—low, middle, and high—were established based on the results. In the subsequent phase, three cell pools were created, each comprising donors from their respective fitness groups. This allowed for collective effects examination within each pool. Simultaneously, individual donor and cell pool experiments were conducted, including cell migration studies, cell senescence measurement, osteogenic differentiation potential, as well as the MTS assay, and PDT calculation. Statistical analyses, particularly one-way ANOVA, revealed interesting findings. The high-fitness group exhibited increased cell viability and shorter PDT, correlating with lower senescence markers. However, osteogenic differentiation and cell migration studies did not show statistical significance across groups. Importantly, pooled cell results aligned well with individual donor cells within fitness groups. In conclusion, this study provides insights into how cellular fitness influences adipose-derived MSCs. The lower senescence rate in the high-fitness group suggests enhanced cell health and functionality. While cell pools accurately represented individual donors within their fitness group, future investigations will explore the influence of donor composition on results. This research lays the groundwork for understanding the intricate interplay between cellular fitness and the therapeutic potential of adipose-derived MSCs, offering valuable insights for further exploration in regenerative medicine.
