Gap Junctions

Gap Junctions

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...

Gap Junctions

Gap Junctions

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...

Pleiotropy

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Renewal of Skin Epidermal Stem Cells

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...

Accessory Structures of the Skin: Sweat Glands

Accessory Structures of the Skin: Sweat Glands

Sweat glands or sudoriferous glands are one of the important accessory structures of the skin. They are small, coiled tubular structures located in the dermis, the middle layer of the skin. Sweat glands are responsible for producing and secreting sweat, a watery fluid that helps regulate body temperature and excrete waste products.
Sweat glands are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There...

Tight Junctions

Tight Junctions

Tight junctions are molecular seals between cells that prevent the leaking of fluids, ions, and other small solutes across cavities and compartments in multicellular organisms. They are mainly composed of claudin and occludin transmembrane proteins, and other proteins such as tricellulin and JAM (junctional adhesion molecule). All these proteins are 4-pass transmembrane proteins, except JAM, which is a single-pass transmembrane protein belonging to the immunoglobulin superfamily. The...

Area of Science:

Developmental Biology
Mathematical Biology
Genetics

Background:

Animal skin patterns are vital for survival, but the underlying formation mechanisms are not fully understood.
Turing's reaction-diffusion model offers a mathematical framework for predicting observed animal skin patterns.

Purpose of the Study:

To investigate the plasticity of pigment cells in generating diverse skin patterns.
To experimentally validate Turing's reaction-diffusion model using transgenic zebrafish.

Main Methods:

Generated artificial skin patterns in transgenic zebrafish by ectopically expressing connexin41.8 (or its mutant form) under the mitfa promoter.
Observed and documented patterns including stripes, labyrinth, and 'leopard' (donut-like ring) formations.

Main Results:

Successfully generated various artificial skin patterns in zebrafish, including narrow/wide stripes, labyrinth, and leopard patterns.
The 'leopard' pattern formation precisely matched predictions from Turing's reaction-diffusion model.
Demonstrated significant potential and plasticity in animal pigment cells for pattern formation.

Conclusions:

Pigment cells possess inherent plasticity to form a wide array of skin patterns.
The reaction-diffusion principle effectively predicts the formation of animal skin patterns, as exemplified by the zebrafish study.
