High-grade endometrial stromal sarcoma is a rare uterine malignancy. The cells of these tumors resemble endometrial cells in the proliferation stage, with many small plexiform arterioles. Herein we present a patient with endometrial stromal sarcoma that metastasized to the brain, along with the CT and MRI findings and a discussion of the surgical and histopathological features of the metastatic...

Bufalin is a traditional Chinese medicine and it induces apoptosis in certain human tumor cell lines. We investigated the effect of bufalin on three endometrial cancer cell lines, two ovarian cancer cell lines, and on normal human endometrial epithelial cells. Endometrial and ovarian cancer cells were treated with various concentrations of bufalin, and its effect on cell growth, cell cycle, apo...

BACKGROUND Histone deacetylase inhibitors (HDACIs) can inhibit cell proliferation, induce cell cycle arrest and stimulate apoptosis of cancer cells. MATERIALS AND METHODS The effects of a novel HDACI, MS-275, on 4 endometrial cancer cell lines and normal human endometrial epithelial cells was investigated. Endometrial cancer cells were treated with various concentrations of MS-275 and its eff...

Endometrial interleukin-6 (IL-6) mRNA has been reported to be suppressed in the mid-secretory phase in patients with recurrent early spontaneous abortions. This prompted our study concerning the regulation of endometrial IL-6 in cell culture models of endometrial epithelial and stromal cells. Steroid-dependent secretion of IL-6 was analysed by 17beta-estradiol (10(-8) mol/l) or progesterone (10...

Endometrial biopsies are useful for evaluating endometrial disease, but the presence of non-endometrial, noncervical tissue is rare and is typically restricted to metastasis to the endometrial cavity. We report, for the first time, a case of an endometrial biopsy seeded with serous cells in a young patient with a known history of a serous borderline tumor of the ovary. Given the patient’s diagn...

Endometrial angiogenesis is not well studied, but has potential as a model for studies of physiological angiogenesis. Migration as well as proliferation of vascular endothelial cells are modulated by other endometrial cells. This study analyzes the chemotactic signal released from endometrial tissue in a wound assay using human microvascular endothelial cells. Endometrial tissue explants stimul...

Under the influence of ovarian steroid hormones, endometrial cells aer able to produce a wide variety of growth factors and peptide hormones that area believed to promote: (1) physiological growth and differentiation during the endometrial cycle; (2) decidualization, an essential preparative event for establishment of pregnancy; and (3) pathological growth and differentiation in endometriosis a...

Bone marrow derived cells engraft to the uterine endometrium and contribute to endometriosis. The mechanism by which these cells are mobilized and directed to the endometrium has not been previously characterized. We demonstrate that human endometrial stromal cells (hESCs) produce the chemokine CXCL12 and that bone marrow cells (BMCs) express the CXCL12 receptor, CXCR4. Treatment with physiolog...

BACKGROUND The presence of conceptus alloantigens necessitates changes in maternal immune function. One player in this process may be the macrophage. In the cow, there is large-scale recruitment of macrophages expressing CD68 and CD14 to the uterine endometrium during pregnancy. METHODOLOGY/PRINCIPAL FINDINGS In the present study, the function of endometrial macrophages during pregnancy was i...

BACKGROUND CD56+ cells in peripheral blood or the endometrium may be increased in women with reproductive failure. However, the relationship between numbers of peripheral blood CD56+ and endometrial CD56+ cells is uncertain. The aim of this study was (i) to compare the numbers of CD56+ cells in peripheral blood and endometrium in samples taken simultaneously and (ii) to compare measurements by ...
