Figure Lengend Snippet: Cytotoxicity assessment of biomaterials enriched with CAPE derivatives on hFOB 1.19 osteoblasts. ( a ) MTT assay conducted by using 24 h extracts of the biomaterials after 48 h cell culture (PS medium—polystyrene extract served as negative control of cytotoxicity; * statistically significant results compared to PS medium, # statistically significant results compared to mat_control, $ statistically significant results compared to mat_ 1d _L, ^ statistically significant results compared to mat_ 1a _L, p < 0.05, One-way ANOVA followed by Tukey’s test); ( b ) confocal laser scanning microscope images showing live/dead staining of cells cultured on the surface of biomaterials for 48 h (Nomarski contrast was applied to show biomaterial microstructure; viable cells—green fluorescence; dead cells—red fluorescence; magnified 100×, scale bar = 200 µm).

Article Snippet: Normal human fetal osteoblast cell line (hFOB 1.19, ATCC CRL-11372) was cultured in a 1:1 mixture of Dulbecco’s Modified Eagle’s Medium and Ham’s F12 Medium, supplemented with 2.5 mM L-glutamine, 0.3 mg/mL G418 (Sigma-Aldrich Chemicals, Warsaw, Poland), and 10% FBS (Pan-Biotech GmbH, Aidenbach, Bavaria, Germany) and maintained at 34 °C (5% CO 2 in air atmosphere).
