Rete pegs (or 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 and junctional epithelia do not. Scar tissue lacks rete pegs and through this scars tend to shear off more easily than normal tissue.
Also known as papillae, they are downward thickenings of the epidermis between the dermal papillae.
