The cytoplasm of uterine epithelial cells contains typical organelles found in other cells, including a nucleus, which is located towards the bottom of the cell with one or more prominent nucleoli, mitochondria, golgi apparatus, endoplasmic reticulum, free ribosomes, lysosomes, vesicles and lipid droplets.

The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus.It has a basal layer and a functional layer: the basal layer contains stem cells which regenerate the functional layer. [1]
The uterus (from Latin uterus, pl.: uteri or uteruses) ... The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus.
Uterine glands or endometrial glands are tubular glands, lined by a simple columnar epithelium, found in the functional layer of the endometrium that lines the uterus. Their appearance varies during the menstrual cycle. During the proliferative phase, uterine glands appear long due to estrogen secretion by the ovaries.
These are enlarged endometrial stromal cells, which resemble epithelium (and are referred to as "epithelioid"). Decidualization includes the process of differentiation of the spindle-shape stromal fibroblasts into the plump secretory decidual cells, which create a pericellular extracellular matrix rich in fibronectin and laminin (similar to ...
During this time, the single-layered paramesonephric duct epithelium differentiates into other structures, ranging from the ciliated columnar epithelium in the uterine tube to stratified squamous epithelium in the vagina. [8] The paramesonephric ducts and the mesonephric ducts share a majority of the same mesenchyme due to Hox gene expression.
A peg cell is a non-ciliated epithelial secretory cell within the uterine tube (oviduct or fallopian tube). [1] These cells represent one of three epithelial cell types found within the normal fallopian tube epithelium and only make up around 10% of the total number of cells. The other two cell types are ciliated columnar and intercalary cells. [1]
About the fifth month a ring-like constriction marks the position of the cervix of the uterus, and after the sixth month the walls of the uterus begin to thicken. For a time the vagina is represented by a solid rod of epithelial cells. A ring-like outgrowth of this epithelium occurs at the lower end of the uterus and marks the future vaginal ...
