Localization of Angptl4 mRNA in implantation (IS) tissue segments from (A–D) Day 9.5 and (E–J) Day 10.5 pregnant mice using in situ hybridization. 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: mm, mesometrial decidua; MLap, mesometrial lymphoid aggregate of pregnancy; pe, parietal endoderm; plac, developing placenta; tgc, trophoblast giant cells; v, vascular endothelium; ve, visceral endoderm.
