Microsphere-Based Bioink for Large Tissue with Angiogenesis
Figure 1. Sketch of the preparation of TSM-B and formation of porous centimeter-scale tissue with angiogenesis.
bioprinting of centimeter-scale 3D structure, the sol- 3D structures were successfully printed with commercial
gel transformation process of sacrificial microspheres 3D bioprinter. Finally, the ability of the bioink to build
inside the printed structure was observed to explore the large vascularized tissue at the centimeter level was
formation of internal nutrient channels. Complex porous verified by in vitro printing human breast tumor tissue
