a Schematic representation of the benefits of photocuring GelMA. b–e Photographs of various stages of the HEA. f TEM image of the HEA. g TEM image of HEA protoplasts. h–i TEM images of AST vesicles released from HEA. j Photographs of Gel, GHEA@Gel, and RHEA@Gel. k The photocrosslinking mechanism of GelMA. Cryo-scanning electron microscopy images of (l) Gel, (m) GHEA@Gel, and (n) RHEA@Gel. Scale bars, 20 μm. The insets in (l–n) represented the photographs of of Gel, GHEA@Gel, and RHEA@Gel, respectively. For these morphological characterizations of the fabricated Gel, GHEA@Gel, and RHEA@Gel, each experiment was repeated three times independently with similar results.
