Other Supplementary Material for this manuscript includes the following:

  • movie S1 (.avi format). Dynamic migration and in situ replication of repopulating microglia in the retina.
  • movie S2 (.avi format). Dynamic migration and replication of repopulating microglia slow down as microglial density increases in the retina.
  • movie S3 (.avi format). Repopulating microglia demonstrate dynamic motility in their processes at baseline and in response to exogenous ATP that are similar to that in endogenous microglia.
