FIG. 1.

Cell morphology and proliferation on PCL scaffolds. (a–c) SEM of the PCL scaffolds without cells. (d–f) The morphology of mRPCs grown on the corresponding PCL scaffolds for 7 days. (g–i) Fluorescent micrographs of mRPCs on the corresponding PCL scaffolds 7 days after plating. (GFP, green) (j) The average cell number of mRPCs cultured on different topographies of PCL scaffolds was calculated at day 1, 3, and 7. Scale bar: 250 μm. mRPC, mouse retinal progenitor cell; PCL, polycaprolactone; SEM, scanning electron microscope. Color images available online at www.liebertpub.com/tea
