Cardiomyocyte cell proliferation on a PLGA density of 0.025 g/mL after (A) 24, (B) 72, and (C) 120 hours on 100 nm diameter PLGA:CNF composite materials of interest in this study.

Notes: Seeding density was 5 × 104 cells/cm². Data are shown as the mean count of n = 3. The control was the glass substrate. *P < 0.05 versus control; **P < 0.05 versus similar PLGA:CNF composite ratios and different densities; ***P < 0.05 versus similar PLGA:CNF composite ratios between 24 and 72 hours, and ****P < 0.05 versus PLGA:CNF composite ratios between 72 and 120 hours.

Abbreviations: CNF, carbon nanofibers; PLGA, poly(lactic-co-glycolic-acid).
