Summary
Two studies reveal a new process called crowding-mediated live cell extrusion that helps maintain epithelial homeostasis. This mechanism tightly controls cell number and quality for a healthy epithelial tissue.
Area of Science:
- Cell biology
- Tissue homeostasis
- Epithelial biology
Background:
- Epithelial tissues require strict regulation of cell number and quality to function properly.
- Maintaining tissue integrity is crucial for organismal health.
Purpose of the Study:
- To elucidate novel mechanisms underlying epithelial homeostasis.
- To identify cellular processes involved in maintaining epithelial tissue balance.
Main Methods:
- Observational studies of epithelial tissues.
- Analysis of cellular behavior under crowded conditions.
Main Results:
- Discovery of a novel cellular process: crowding-mediated live cell extrusion.
- Demonstration of this process's role in regulating cell number in epithelial tissues.
Conclusions:
- Crowding-mediated live cell extrusion is a key mechanism for epithelial homeostasis.
- This process contributes to the maintenance of functional and harmonious epithelial tissues.

01:23Transcellular Transport of Solutes
Transcellular transport of solutes is the movement of substances like monosaccharides and amino acids through polarized cells. This transport mechanism is primarily seen in epithelial and endothelial cells aided by membrane transport proteins such as channels and transporters. The tight junctions between these cells confine the membrane proteins to the two sides of the cell. The epithelial cells have distinct apical and basolateral domains. In contrast, the endothelial cells show the luminal...
02:12What Are Osmoregulation and Excretion?
Organisms must keep bodily fluids at a constant temperature and pH while maintaining specific solute concentrations in order to support life functions. Osmoregulation is the process that balances solute and water levels.
01:23Epithelial Tissues and Their Functions
Epithelial tissues are large sheets of cells covering all of the surfaces of the body. These surfaces can be internal or external, for example, skin, airways, the digestive tract, the urinary system, and the reproductive system. Hollow organs and body cavities that do not connect to the body's exterior, including blood vessels and serous membranes, are lined by epithelial tissue known as the endothelium.

01:30Classification of Epithelial Tissues: Simple Epithelium
Simple epithelium consists of a single layer of cells that lines body cavities and blood vessels. The shape of the cells in the epithelium reflects the function of the tissue. Cells in simple squamous epithelium appear as thin scales with flat, elliptical nuclei that mirror the form of the cell.
Because of the thinness of the cells, simple squamous epithelium is present where the rapid passage of chemical compounds is observed. For example, the endothelium that lines the capillaries and vessels...

01:20Classification 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.

01:16Cell Motility through Blebbing
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.
