Developments and Clinical Applications of Biomimetic Tissue Regeneration using 3D Bioprinting Technique

Figure 8

The bioprinted templates (green) are encased in GelMA hydrogels, and fluorescent microbead suspensions are perfused through the microchannels (pink). (A) Bifurcating planar bioprinted templates in a GelMA hydrogel construct and corresponding (A-i) postperfusion networks. (B) The 3D branching agarose templates embedded in the GelMA hydrogel construct and (B-i) the resulting 3D branching network. (C) GelMA hydrogel with a 3D lattice template inside it, and the results (C-i) before and after perfusion.
