Abstract (original English)

Introduction Human adipose-derived stem cells (hADSCs) are considered a promising source for cell replacement therapy in degenerative and traumatic conditions. This study explores the effects of phenylacetate and calcium on the neural differentiation of hADSCs for regenerative medicine. We assessed cell viability and cytotoxicity using the MTT assay, revealing that treatment with 1μM phenylacetate significantly enhanced cell viability compared to control groups over five days, while higher concentrations resulted in cytotoxic effects. Method Additionally, qualitative analysis through Acridine orange/ethidium bromide (AO/EB) staining indicated normal cellular characteristics at lower phenylacetate concentrations, whereas higher doses led to observable cell death. A subsequent evaluation of intracellular calcium levels demonstrated a significant increase when hADSCs were treated with both phenylacetate and calcium. Results The neural differentiation potential was further assessed through the relative quantification of neuronal-specific genes, showing marked upregulation of NSE, Oligo-2, β-tubulin III , and MAP-2 in all treatment groups compared to controls. Immunohistochemistry confirmed elevated protein expression of neural markers in cultures supplemented with phenylacetate and calcium. Conclusion These findings suggest that phenylacetate, particularly in conjunction with calci
