This cell division is regulated by microglia; however, the underlying mechanism remains unknown. Here, we report that MG-derived Il34 attracts microglia to sites of retinal injury where they stimulate MG proliferation via the release of cytokines, like M17, Spp1, Tnfa, and Tnfb. Remarkably, RNA sequencing analysis of MG\u2019s regeneration-associated transcriptome with and without microglia depletion suggests microglia stimulate MG proliferation by preferentially enhancing the expression of regeneration-associated genes involved in cell division\u2013related processes. In contrast, genetic ablation of essentially all microglia from early development appears to reprogram MG, so they exhibit enhanced injury-dependent proliferation, but their survival is compromised. Our studies illustrate the profound effects MG-microglia cross talk can have on MG transcriptional programs related to cell division processes.<\/jats:p>","DOI":"10.1073\/pnas.2535044123","type":"journal-article","created":{"date-parts":[[2026,4,21]],"date-time":"2026-04-21T16:25:41Z","timestamp":1776788741000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":2,"title":["M\u00fcller
