Fig. 1

A graphical representation of selected panel of epithelial genetic markers associated with oviduct cells. Three panels of epithelial genetic markers were proposed to provide a pattern of molecular signatures in the oviduct of hen and quail in 3 compartments: INF – infundibulum, DM – distal magnum, PM – proximal magnum. The first panel shown in the picture refers to stem-like markers: Nanog homebox (NANOG), octamer-binding protein 4 (OCT4/cPOUV) and sex determining region Y-box 9 (SOX9); and epithelial progenitor cells: cell surface glycoprotein CD44, leucine-rich repeat containing G protein-coupled receptor 5 (LGR5), and Musashi-1 (MSI-1). The second panel refers to epithelial cells: keratins KRT 5 and 14 and occludin (OCLN). The third panel refers to functional avian oviduct cells: estrogen receptor-1 (ESR1), ovalbumin (OVAL) and ovomucoid (OVM)
