Core/Shell printing facilitates a layer by layer deposition of cell-laden hydrogels with structural integrity. Representative epifluorescent image of Calciein-AM (green channel) stained cells after 7 days from printing. The Shell and the Core has been differently labeled with fluorescent beads (cyan channel for Shell, violet channel for Core) to estimate the compartmentalization. An epifluorescent Olympus IX70 inverted microscope with a SPOT Diagnostic RT-Slider camera and SPOT Diagnostic software was used with an Olimpus 4X UPlanFL NA0.13 objective lens.
