The image was produced by confocal laser scanning microscopy of XY mouse embryonic gonads at 12.5 days post-coitum. Sertoli cells, stained by indirect fluorescence for SOX9 (purple), enclose gonocytes marked by PECAM (green) in testis cords. Testicular vasculature outside cords is visualized by endothelial cell staining for PECAM (See Capel et al.).
