Single Cell Force Spectroscopy was applied to measure the single cell de-adhesion between human neural stem cells (hNSC) and gelatin methacrylate (GelMA) hydrogel with varying modulus in the range equivalent to brain tissue. The cell de-adhesion force and energy were predominately generated via unbinding of complexes formed between RGD groups of the GelMA and cell surface integrin receptors and the de-adhesion force/energy were found to increase with decreasing modulus of the GelMA hydrogel. For the softer GelMA hydrogels (160 Pa and 45
