Movie 7

Microglial uptake of cellular debris is reduced in adgrb1a/b crispants. In a mpeg1:GFP animal injected with adgrb1a/b gRNAs, a microglial cell extends a process towards a PI⁺ cell but does not proceed to phagocytose it. The movie was recorded from 30 to 66 min following injury. Scale bar, 15 μm.
