Manipulating the Murine Lacrimal Gland
Published on: November 18, 2014
Summary
Granulated metrial gland (GMG) cells in pregnant rodents originate from bone marrow. These GMG cells likely play a crucial role in the maternal-fetal immunological relationship.
Area of Science:
- Reproductive biology
- Immunology
- Developmental biology
Background:
- The metrial gland is a key component of the pregnant rodent uterus.
- Granulated metrial gland (GMG) cells are a significant cellular component within this structure.
Purpose of the Study:
- To review current knowledge on the metrial gland and its GMG cells.
- To explore the origin and function of GMG cells in pregnancy.
Main Methods:
- Literature review of existing research on metrial gland and GMG cells.
- Analysis of studies investigating cell differentiation and interactions.
Main Results:
- GMG cells are shown to differentiate from bone marrow-derived cells.
- Evidence suggests GMG cells are integral to the maternal-fetal immunological dialogue.
- A complex interplay is proposed between GMG cells, metrial gland stromal cells, and placental cells.
Conclusions:
- GMG cells represent a unique cell type with a bone marrow origin.
- These cells are critical for establishing and maintaining maternal-fetal immune tolerance.
- Functional interactions between GMG cells and placental cells are likely essential for a successful pregnancy.

Classification of Epithelial Tissues: Glandular Epithelium
The glandular epithelium is made of one or more epithelial cells modified to synthesize and secrete chemical substances. Glandular epithelia can be classified based on cell number. Unicellular glands have individual secretory cells scattered across the epithelial monolayer. In contrast, multicellular glands consist of a hollow tubular duct attached to the cluster of secretory cells located in the deep pockets.

Exocrine Glands: Unicellular and Multicellular Glands
Exocrine glands are classified as unicellular and multicellular. The unicellular glands are scattered single cells, such as goblet cells, found in the mucous membranes of the small and large intestines. On the other hand, multicellular exocrine glands develop as secretory sheets, like the internal lining of the abdomen or chest. Such secretory sheets release their secretions directly into the lumen of these organs. In addition, some multicellular glands have deep-seated secretory units to...
Exocrine Glands: Methods of Secretion
Exocrine glands are those that release their secretions through ducts. Based on their mode of secretion, they can be classified into merocrine, apocrine, and holocrine.
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine glands...

The Thyroid Gland
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

The Pineal Gland
The pineal gland, a diminutive endocrine structure named for its pinecone-shaped appearance, is situated atop the third ventricle within the diencephalon region of the forebrain. This gland, composed of secretory cells known as pinealocytes arranged in compact cords and clusters around dense particles of calcium salts, plays a pivotal role in hormonal regulation.
The primary secretion of the pineal gland is the hormone melatonin, derived from serotonin. The concentration of melatonin in the...

Accessory Glands of the Male Reproductive System
The accessory ducts involved in sperm maturation and transportation include the epididymides, vasa deferentia, ejaculatory ducts, and urethra. These ducts play a critical role in the maturation, storage, and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle. The epididymis can be divided into three main parts: the head, body, and tail. The head of the epididymis...
