Cytoskeleton morphology of BMSC at day 14 of culturing: (a) 3D view of 3D bioprinted BMSC in GelMA and GelMA/Alg scaffolds to evaluate the morphology of BMSC on the surface of the scaffolds. (b) Cross-section view of the bioprinted BMSC to evaluate the morphology of BMSC inside the bioprinted constructs (F-actin (green), Cx43 (red), nucleus (blue)).
