Localization of Angptl4 mRNA in non-implantation (NIS) and implantation (IS) tissue segments from Day 6.5–8.5 pregnant mice by in situ hybridization. (A) Day 6.5 NIS, (B–G) Day 6.5 IS, (H–N) Day 7.5 IS and (O–T) Day 8.5 IS. These are representative of at least 3 independent samples. Global linear adjustments of the brightness and color level were made on the photomicrographs to more accurately represent what was seen on the slides under the microscope. Numbers above scale bars are in microns. Abbrev: am, antimesometrial decidua; c, conceptus; cm, circular smooth muscle layer; endo, endometrium; epc, ectoplacental cone; ge, glandular epithelium; lm, longitudinal smooth muscle layer; m, mesometrium; MLap, mesometrial lymphoid aggregate of pregnancy; mm, mesometrial decidua; myo, myometrium; pe, parietal endoderm; plac, developing placenta; tgc, trophoblast giant cells; v, vascular endothelium.* Denotes area of higher magnification inset in the panel.
