A) Maximum intensity projection of dried lyo-μgels (scale bar = 100 μm). B) After freeze-drying, rehydration of lyo-μgels is shown to take approximately 20 min (scale bar = 100 μm). C) Lyo-μgels can be rehydrated at varying wt % MAP to produce jammed μgels (scale bar = 100 μm). D) Increasing the wt % MAP when rehydrating lyo-μgels alters the particle fraction in MAP scaffolds, as shown by single Z-slices of MAP scaffolds and volume projections (scale bar = 100 μm). E) Using these user-defined wt % MAP scaffolds, unique particle fractions can be achieved (NL = non-lyophilized μgels). Reprinted from Acta Biomaterialia, Volume 150, Alexa R.
