Buechler et al. show that large cavity macrophages (LCMs), which rely on the retinoic-acid-responsive transcription factor GATA6, are found in all visceral cavity spaces. Wt1+ mesothelial and fibroblastic stromal cells maintain the LCM transcriptome in part via the generation of retinoic acid and are required for LCM homeostasis in vivo.
