Summary
Gap junctions (GJs) regulate anatomical patterns by controlling cell communication networks. This review explores their role in tissue development, regeneration, and disease, proposing new applications in regenerative medicine.
Area of Science:
- Developmental Biology
- Cell Biology
- Biophysics
Background:
- Gap junctions (GJs) facilitate direct cell-to-cell communication through aqueous channels.
- While their role in single-cell function is established, their impact on large-scale anatomical patterning is increasingly recognized.
Purpose of the Study:
- To review recent findings on the role of gap junctional connectivity in regulating anatomical patterns.
- To propose a new perspective on GJs as regulators of global bioelectric dynamics in non-neural tissues.
Main Methods:
- Review of recent scientific literature and data.
- Analysis of GJ roles in specific developmental and regenerative processes.
Main Results:
- GJs dynamically regulate bioelectric network topology, enabling complex morphogenesis.
- Evidence presented for GJ roles in zebrafish fin growth, left-right patterning, cancer, and planarian regeneration.
Conclusions:
- Gap junctions are crucial for large-scale anatomical patterning and bioelectric network dynamics.
- Future research can leverage GJ-mediated dynamics for applications in birth defects, regenerative medicine, and bioengineering.

Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

01:19Contact-dependent Signaling
48.4K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

03:14Notch Signaling Pathway
6.8K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

19.1K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...
