Fig 1: Biocompatibility of tested ceragenins in relation to host cells. Hemoglobin release from isolated erythrocytes and viability of HGF-1 (ATCC CRL-2014™) cells upon exposure to LL-37, CSA-13, CSA-44, CSA-131, and CSA-255, omiganan (at doses ranging from 1 to 50 µg/mL) and mouthwashes (at concentrations from 1 to 50%) is presented on panels (A,B), respectively. Morphology HGF-1 (ATCC CRL-2014™) subjected to compounds is presented in panel (C). For panels (A,B), the results from four measurements are shown. For panel (C), results from one representative experiment are shown. Scale ~100 µm. Underlined values (panel (A)) and * (panel (B)) indicate statistically significant results when compared to untreated control samples (p < 0.05).
