(A) Viability of HUVECs seeded directly on polymer surfaces at specified timepoints, where @ = significantly different from TCPS, * = significantly different from 1% agarose, and ** = significantly different from 100%PCL as well as 1% agarose (if located above the 1% agarose bar, the only significant difference is to 100%PCL) (n = 4, p < 0.05). Confocal microscopy images of human coronary artery endothelial cells (hCAECs) 3 days post-seeding on (B) TCPS, (C) 100%PCL, (D) 96%PCL-04%ACPCL, (E) 89%PCL-11%ACPCL, and (F) 88%PCL-12%ACPCL exhibit trademark cobblestone morphology (Green: F-actin, Blue: Nuclei).
