Morphological examination (A–C) and cell viability (D) of hAD-MSCs encapsulated with a UV dose of 1.2 J/cm² in 5% GelMA with 50% degree of functionalization (DoF) formulated with 50% PBS and 50% FCS, 50% HS, or 50% hPL. The hydrogels were cultivated in (A) FCS, (B) HS, or (C) hPL supplemented medium. After cultivating the cells for 1, 3, and 7 days, they were stained with calcein-AM; 4× objective, scale bar 500 μm. (D) The CellTiter-Blue (CTB) assay was performed on day 1, day 3, and day 7 of cultivation. Data represent the mean ± SD for a threefold determination. *p < 0.05, **p < 0.01, ***p < 0.001.
