Abstract (original English)

Skin aging involves changes in extracellular matrix components, such as wrinkles and pigmentation. Caviar extract (CE) is a promising compound for skin rejuvenation, but effective topical delivery requires optimized carriers. This study evaluated polyvinyl alcohol/carboxymethyl chitosan (PVA/CMC) hydrogels loaded with CE at concentrations of 2%, 3.5%, and 5% as scaffolds to influence the epithelial differentiation of adipose-derived mesenchymal stem cells (ADMSCs). Hydrogels were synthesized using a freeze-thaw method and characterized by Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy, swelling and degradation tests, and mechanical analysis. Biocompatibility and cell migration were assessed using MTT and scratch assays; at the same time, expression of cytokeratin-18 ( CK-18 ) and pan-cytokeratin (pan-CK) was measured via reverse transcription-quantitative polymerase chain reaction and immunocytochemistry (ICC), respectively. FTIR confirmed successful CE incorporation, and SEM revealed a porous structure. Hydrogels with 3.5% and 5% CE demonstrated a good balance between swelling and degradation over 336 h. The biocompatibility tests showed that 5% CE supported enhanced long-term cell growth. The scratch assay indicated improved cell migration, and transcriptional analysis revealed significantly higher CK-18 levels in ADMSCs treated with PVA/CMC/CE 5
