VEGF production is altered by scaffold geometry. BMMC were seeded on the indicated fibronectin-coated electrospun scaffolds for 48 h and then activated with IL-33 (100 ng/mL). Supernatants were collected 16 h later and analyzed via ELISA for VEGF. Results are presented as mean ± SEM of eight to nine samples from three independent experiments. **, p < 0.01; ***, p < 0.001.
