Fig. 6From: Control of maleic acid-propylene diepoxide hydrogel for 3D printing application for flexible tissue engineering scaffold with high resolution by end capping and graft polymerizationA Cytotoxicity assays of the extracts from Teflon, latex, the LP-capped gel, and MPLE gel (1:0.3) samples. B Representative Live/Dead (MC3T3-E1 cells) images by the extracts of (a) Teflon (negative control), (b) Latex (positive control), (c) the LP-capped gel, (d) the MPLE gel (1:0.3). C In vitro release profiles of a BSA protein and ORN drug from the 3D-printed MPLE gel (1:0.3), where (a) BSA was incorporated inside gel, (b) ORN incorporated inside, (c) adsorbed onto the 3D printed gels.
