It turns out... yes! Cell viabilities were significantly lower for gels with stronger crosslinks (but the same stiffness!) (6/8)

We calculated a "yielding speed" which correlated nicely with the crosslink strength. (4/8)

We used techniques to extract data about the speed of the yielding transition from rheological measurements. From these, we could see that the less dynamic materials have a more brittle, or sudden transition, versus a more smooth one. (3/8)

Dynamic hydrogels allow flexible delivery of cells, due to the ability of crosslinks to break and re-form. We analyzed three clinically relevant, dynamic gels with similar stiffness to see how changing crosslink dynamics would change the physics of the yielding transition (2/8)
