Biocompatibility of the PCU-Sil and 3D printing. a) Cell viability for PCU-Sil pellets, 3D-printed PCU-Sil samples, and controls obtained following a seven-day cell culture (asterisk indicates statistical significance, p < 0.05), b) Normalized NO production after seven days in cell culture (no statistically significant differences between all pairs, p > 0.05). c) HPMEC activation was not observed upon exposure to PCU-Sil pellets or 3D-printed PCU-Sil samples, as determined by intact VE-cadherin-mediated cell-cell junctions and a quiescent pattern of actin cytoskeletal organization. (All scale bars are 40 μm)
