Expression and localization of <i>Npl</i> in the periimplantation mouse uterus.

<p>A. Expression of <i>Npl</i> in the periimplantation wild type (WT) uterus using realtime PCR. N = 4–6. * p<0.05, compared to gestation day 0.5 (D0.5); ^# p<0.05, compared to D1.5 and D4.5. <i>Gapdh</i> (glyceraldehyde 3-phosphate dehydrogenase), a house keeping gene as a loading control; error bars, standard deviation. B–G. Localization of <i>Npl</i> in the periimplantation uterus by <i>in situ</i> hybridization using <i>Npl</i> antisense probe. B. D0.5 WT (+/+) uterus. C. D1.5 WT uterus. D. D2.5 WT uterus. E. D3.5 WT uterus. F. D4.5 WT uterus. G. D3.5 <i>Npl</i>^(−/−) uterus. Red star, embryo; LE, luminal epithelium; S, stroma; D, decidual zone; scale bar, 50 µm. N = 2–3.
