Single-cell RNA sequencing reveals the heterogeneity and interactions of immune cells and Muller glia during zebrafish retina regeneration.

ABSTRACT: JOURNAL/nrgr/04.03/01300535-202512000-00031/figure1/v/2025-01-31T122243Z/r/image-tiff Inflammation plays a crucial role in the regeneration of fish and avian retinas. However, how inflammation regulates Müller glia (MG) reprogramming remains unclear. Here, we used single-cell RNA sequencing to investigate the cell heterogeneity and interactions of MG and immune cells in the regenerating zebrafish retina. We first showed that two types of quiescent MG (resting MG1 and MG2) reside in the uninjured retina. Following retinal injury, resting MG1 transitioned into an activated state expressing known reprogramming genes, while resting MG2 gave rise to rod progenitors. We further showed that retinal microglia can be categorized into three subtypes (microglia-1, microglia-2, and proliferative) and
