Sectioning of hydrogel specimen for cell viability experiments. (a) The cured cell infused hydrogel is placed in a custom-made holder equipped with micrometer. The micrometer allows for small increments of PEGDA hydrogel to be pushed outside of the tube to be sliced. (b) Thin hydrogel slices are obtained to be later analyzed under the microscope.
