The mammalian uterus contains glands in the endometrium that develop only or primarily after birth. In the mouse, endometrial glands govern post implantation pregnancy establishment via regulation of blastocyst implantation, stromal cell de…

Endometriosis, characterized by the growth of uterine-like tissue outside the uterus, causes chronic pain and infertility. Current diagnostic and therapeutic strategies have notable limitations, including delayed diagnosis and adverse effec…

Embryo implantation is a critical event in the establishment of pregnancy, and implantation failure is a major cause of pregnancy loss in women. Coordinated, cell-type specific responses to the ovarian steroid hormones, estrogen, and proges…

The uterine epithelium is composed of a single layer of hormone responsive polarized epithelial cells that line the lumen and form tubular glands. Endometrial epithelial organoids (EEO) can be generated from uterine epithelia and recapitula…

Postnatal development of the uterus involves specification of undifferentiated epithelium into uterine-type epithelium. That specification is regulated by stromal-epithelial interactions as well as intrinsic cell-specific transcription fact…

The uterus is vital for successful reproduction in mammals, and two different types of epithelia (luminal and glandular) are essential for embryo implantation and pregnancy establishment. However, the essential cellular and molecular factor…

The pioneer forkhead box (FOX)A2 transcription factor is specifically expressed in the glands of the uterus, which are central to endometrial function and fertility. In mice, FOXA2 is a critical regulator of uterine gland development in the…

All mammalian uteri contain glands in the endometrium that develop only or primarily after birth. Gland development or adenogenesis in the postnatal uterus is intrinsically regulated by proliferation, cell-cell interactions, growth factors …

Forkhead box A2 (FOXA2) is a pioneer transcription factor involved in organ development, function, and cancer. In the uterus, FOXA2 is essential for pregnancy and expressed specifically in the glands of the endometrium. Loss of FOXA2 functi…

Establishment of pregnancy is a critical event, and failure of embryo implantation and stromal decidualization in the uterus contribute to significant numbers of pregnancy losses in women. Glands of the uterus are essential for establishmen…
