Fig. 8From: Systematic review on the application of 3D-bioprinting technology in orthoregeneration: current achievements and open challengesFunctional evaluation of prevascularized spheroid-laden bioprinted scaffolds by a CAM-assaya Overview of bioprinted sample on the CAM, scale bar = 5 mm. b Macroscopic and stereomicroscopic images of empty scaffolds and spheroid-laden scaffolds on the CAM. Overview scale bars = 5 mm and magnification scale bars = 500 µm. c Details of spheroid-laden scaffolds on the CAM. Branching of CAM microvessels and inosculation of CAM microvasculature with the spheroids (indicated by the black arrows). Scale bars = 200 µm.
