Figure Lengend Snippet: Cytocompatibility of Cu-PIAS. ( A ) Viability, as measured by ATP content, of human umbilical vein endothelial cells cultured with media containing extracts of 15-Cu-PIAS, Latex (Positive), or PCL (Negative) over three days. ( B ) Representative images of cell morphology after 24 h exposure to material extract-containing media, visualized by Calcein AM (Green) staining. Additional staining with ethidium homodimer-1 (red) indicates the presence of non-viable cells.

Article Snippet: Briefly, endothelial growth medium supplemented with 5% fetal bovine serum, growth factors, ascorbic acid, and hydrocortisone (Promocell C-22121) was incubated at 37 °C for 72 h under agitation alone, or in the presence of 15-Cu-PIAS (6 cm 2 /mL), PCL (6 cm 2 /mL), or latex (3 cm 2 /mL) sheets cut into several 6 mm × 6 mm squares.
