Summary
E-cadherin levels increase during zebrafish embryonic skin development, driving cell shape changes and hexagonal packing. This study quantifies E-cadherin
Area of Science:
- Developmental Biology
- Cell Biology
- Biophysics
Background:
- E-cadherin is a key adhesion receptor in epithelial adherens junctions (AJs).
- E-cadherin regulates cell shape, size, and packing density to maintain epidermal tissue integrity.
- Its role in zebrafish embryonic epidermis development is not well understood.
Purpose of the Study:
- To quantitatively assess the spatial and temporal distribution of E-cadherin in zebrafish embryonic epidermis.
- To correlate E-cadherin levels with changes in cell morphology and tissue organization.
Main Methods:
- Utilized immunofluorescence, deconvolution microscopy, and 3D segmentation of adherens junctions (AJs).
- Quantified E-cadherin distribution in zebrafish epidermis between 24 and 72 hours post-fertilization (hpf).
Main Results:
- E-cadherin protein levels increased significantly between 31 and 48 hpf.
- Higher E-cadherin correlated with increased cell density and hexagonal cell shapes in the enveloping layer (EVL).
- New cell-cell contacts were established in the epidermal basal layer (EBL).
Conclusions:
- Increasing E-cadherin levels are associated with significant cell shape modulation towards hexagonal packing.
- This process is crucial for epidermal morphogenesis during zebrafish embryonic development.

01:25Structure of Cadherins
4.8K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

01:24Cells of the Epidermis
7.1K
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

01:19Cadherins in Tissue Organization
4.0K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

01:21Layers of the Epidermis
8.3K
The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

01:06Fixed Action Patterns
17.6K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.
