Simple hyperplasia versus proliferative endometrium: stereological study
unitermos abstract The diagnosis of some forms of hyperplastic endometrium continues to present difficulties for the practicing pathologist. One of the major problems is the lack of a standard terminology for endometrial classification. Therefore, morphometrical techniques could help the accurate diagnosis. Thirteen samples of endometrium with simple hyperplasia and thirteen samples of prolifer...
متن کاملAngiogenesis occurs by vessel elongation in proliferative phase human endometrium.
BACKGROUND Angiogenesis occurs by at least three mechanisms: sprouting, intussusception and elongation. Studies to date have failed to identify the mechanisms or timing of endometrial angiogenesis during the menstrual cycle. The aim of this study was to determine if vessel elongation plays a role in human endometrial angiogenesis. METHODS Forty-nine full thickness endometrial sections from 27...
متن کاملبررسی بروز PTEN به‌روش ایمنوهیستوشیمی در آندومتر پرولیفراتیو نرمال، هیپرپلاستیک و کارسینوم آندومتریوئید
Background: Endometrial carcinoma is the most common malignancy of the female genital tract. Different molecular alterations have been described in endometrioid endometrial carcinoma that, the most frequently altered gene is mutations of PTEN. Up to 50-83% of endometrioid carcinoma reveal altered PTEN characterized by loss of expression. In endometrial hyperplasia, which are precursors of endom...
متن کاملEstrogen signaling in the proliferative endometrium: implications in endometriosis.
Even though the physiological role of estrogen in the female reproductive cycle and endometrial proliferative phase is well established, the signaling pathways by which estrogen exerts its action in the endometrial tissue are still little known. In this regard, advancements in cell culture techniques and maintenance of endometrial cells in cultures enabled the discovery of new signaling mechani...
متن کاملMolecular and hormonal regulation of angiogenesis in proliferative endometrium
Angiogenesis is the process of formation of new blood vessels from the blood vessels that already exist. This process is an essential factor in each menstrual cycle. Neovascularisation or formation of new blood vessel is the process occurs often in endometrium during every menstrual cycle. Abnormal angiogenesis may have a profound effect on the pathogenesis of endometrial carcinoma and abnormal...
