Lumen formation in salivary gland development.
Frontiers of Oral Biology
|April 30, 2010
Summary
Salivary gland lumen formation involves programmed cell death and cell-cell junction development. These processes are crucial for creating the tubular structures essential for saliva transport during development.
Area of Science:
- Developmental Biology
- Cell Biology
- Histology
Background:
- Salivary gland morphogenesis requires the formation of hollow lumens within ducts and acini.
- Lumen formation is essential for saliva passage and modification.
- Understanding the molecular mechanisms of lumenogenesis is a key research area.
Purpose of the Study:
- To discuss the mechanisms involved in salivary gland lumen formation during development.
- To highlight the role of programmed cell death and cell-cell junctions.
- To review recent research in this field.
Main Methods:
- Histological studies to observe lumen formation.
- Analysis of apoptotic cell presence during morphogenesis.
- Investigation of cell-cell junction formation.
Main Results:
- Lumen formation initiates during mid-stage branching morphogenesis.
- Apoptotic cells are detected at sites of lumen formation, suggesting a role for programmed cell death.
- Cell-cell junctions are integral, forming a barrier and enabling cell specialization.
Conclusions:
- Programmed cell death (apoptosis) is instrumental in clearing luminal space during salivary gland development.
- The formation of robust cell-cell junctions is critical for establishing and maintaining the salivary gland lumen.
- These mechanisms collectively facilitate the creation of the tubular salivary duct system.

01:06Lipid Digestion
Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.
01:29Exocrine 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...
01:07Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

01:15Development of the Lymphatic System
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

01:26Alveoli and Alveolar Ducts
The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...
01:23Salivary Glands and Saliva
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
