Figure 6. SEM of HCE-T cells seeded over nanofibers to evaluate the attachment ability at different time intervals. A: SEM after 6 h post seeding shows almost no cell attachment. B: After 1st day, cells attached to the polymer surface, become large and flat in morphology. C: After 3rd day, SEM revealed confluent monolayer formation over nanofibers with good cell spreading. D: Micrograph on the 5th day depicted good cell attachment and spreading on the nanofibers surface. E: Micrograph on day 7 illustrated confluent epithelial layer over nanofibers surface similar as day five.
