Fig. 3.

(a) Composite image of microbeads embedded in a photopolymerized GelMA-Matrigel hydrogel. Scale bar: 250 μm. (b) Maximum intensity projection images of two different microchambers after embedding and melting of the gelatin microbeads. Live and dead cells within the chambers were labelled with calcein AM (green) and ethidium homodimer-1 (magenta), respectively. Scale bar: 50 μm.
