| contents | Light Exposure as a Tool to Enhance the Regenerative Potential of Adipose-Derived Mesenchymal Stem/Stromal Cells. Sridharan, Kaarthik Waheed, Tawakalitu Okikiola Staehlke, Susanne Riess, Alexander Mand, Mario Meyer, Juliane Seitz, Hermann Peters, Kirsten Hahn, Olga Mesenchymal Stem Cells Humans Cell Proliferation Adipose Tissue Cell Movement Reactive Oxygen Species Cell Differentiation Light Cell Survival Adipogenesis Cells, Cultured Regeneration Photobiomodulation (PBM) utilizes different wavelengths of light to modulate cellular functions and has emerged as a promising approach in regenerative medicine. In this study, we examined the effects of blue (455 nm), red (660 nm), and near-infrared (810 nm) light, both individually and in combination, on human adipose-derived mesenchymal stem/stromal cells (adMSCs). A single, short-term exposure of adMSCs in suspension to these wavelengths using an integrating sphere revealed distinct wavelength- and dose-dependent cellular responses. Blue light exposure led to a dose-dependent increase in intracellular reactive oxygen species, accompanied by reduced cell proliferation, metabolic activity, interleukin-6/interleukin-8 secretion, and adipogenic differentiation. In contrast, red and near-infrared light preserved cell viability and metabolic function while enhancing cell migration, consistent with their documented ability to stimulate proliferation and mitochondrial activity in mesenchymal stem cells. These findings highlight the necessity of precise wavelength and dosage selection in PBM applications and support the potential of PBM as a customizable tool for optimizing patient-specific regenerative therapies. |
