(A) Representative confocal micrographs of f-actin/nuclei staining after 21 days of culture post bioprinting (6.9 mW cm−2 UV for 30 s), showing different layers of the hollow fibers (I and II), longitudinal cross-section (III), and surface (IV) of the tubes, as well as 3D reconstruction indicating the perfusable vessel-like structure lined with vascular cells (V). (B) Confocal images of the vascular structure containing αSMA-expressing MSCs and CD31-expressing HUVECs after 14 (I) and 21 (II) days of culture.
