reproductive system
N
• females exhibit normal ovulation, fertilization, and ovarian histology relative to control mice
• at day 5.5 of gestation (GD 5.5), embryos are free-floating within the uterine lumen and no decidual cells are observed, unlike in control uteri
• following artificially induced decidualization, the ratio of uterine weight to body weight is significantly lower than that in control mice, indicating a decidual defect; mRNA expression of decidualization marker genes Wnt4 and Bmp2 is significantly reduced in the uterus
• at GD 3.5, the expression of stromal markers vimentin and COUP-TFII is significantly reduced in endometrial stromal cells
• immunohistochemical staining showed significantly increased collagen type I protein levels in endometrial stromal cells at GD 3.5, suggesting that endometrial stroma is largely replaced by fibrous tissue
• at GD 5.5, embryos are free-floating within the uterine lumen, unlike in control uteri
• no implantation sites are detected in the uterine horns at GD 5.5
• at GD 3.5, Ki-67 staining revealed significantly altered proliferative responses in the uterine stromal and epithelial compartments: the % of Ki-67+ endometrial epithelial cells is increased whereas the % of Ki-67+ stromal cells is decreased, unlike in control uteri
• expression of estrogen receptor 1 alpha (ESR1) and progesterone receptor (PGR) is significantly reduced in endometrial stromal cells at GD 3.5, indicating decreased progesterone signaling
• adult females are completely sterile primarily due to a uterine defect

embryo
• at day 5.5 of gestation (GD 5.5), embryos are free-floating within the uterine lumen and no decidual cells are observed, unlike in control uteri
• following artificially induced decidualization, the ratio of uterine weight to body weight is significantly lower than that in control mice, indicating a decidual defect; mRNA expression of decidualization marker genes Wnt4 and Bmp2 is significantly reduced in the uterus

homeostasis/metabolism
N
• at GD 3.5, females exhibit normal serum progesterone and estrogen levels relative to control mice
• H&E and Massons trichrome staining revealed increased collagen levels in uterine stromal cells starting at 6 weeks of age
• immunohistochemical staining showed significantly increased collagen type I protein levels in endometrial stromal cells at GD 3.5
