Rete pegs (also known as rete processes or rete ridges) are the epithelial extensions that project into the underlying connective tissue in both skin and mucous membranes. In the epithelium of the mouth, the attached gingiva exhibit rete pegs, while the sulcular [2] and junctional epithelia do not. [3] .
1 sty 2023 · Rete ridges (RRs) are distinct undulating microstructures at the junction of the dermis and epidermis in the skin of humans and certain animals. This structure is essential for enhancing the mechanical characteristics of skin and preserving homeostasis.
The epidermis forms an undulating appearance, with intermittent regular protrusions of the epidermis layer (rete ridges or pegs) into the upper layers of the underlying dermis. In some areas of the body such as the palms and soles, the rete pegs are less pronounced.
Rete ridges surround the dermal papillae, which can be seen as small extensions protruding from the papillary dermis within the epidermis. These two structures are perfectly embedded; the alternation of a rete ridge with a dermal papilla creates a characteristic repetitive and wave-shaped pattern.
25 lis 2015 · Rete ridges occur where the epidermis is thickest and extend deep into the dermis. Fibroblasts (yellow) are present throughout the dermis. Nerves and Schwann cells (light blue) are present in a complex arrangement throughout the dermis.
During human skin development, specific interactions between epidermal and dermal cell lineages give rise to fully functional skin that contains specialized appendages, including hair follicles, sweat glands, and rete ridges.
