Resident macrophages in adult testis and epididymis originate from different waves of embryonic hematopoiesis

Macrophages are principal immune cells of the epididymis and testis. Here we described that epididymal and testicular macrophages share core markers with tissue macrophages of other organs while concomitantly expressing a unique set of genes to perform organ specific functions. Overall design: Analysis of the RNA expression in distinct organ derived macrophage.
