Dermis pushes up on the epidermis during development, causing buckling of the epidermis and friction ridges (our fingerprints) How do these form, and why is that significant? This tissue is composed of epidermal cells, which are clustered cells that secrete a waxy cuticle, which plays a role in preventing water loss. Subsequently, one may also ask, why is a leaf An example of an organ? However, if co-transplanted on acellular dermal matrix, this effectively inhibited scar formation and pruritus, providing an alternative method to treat hypertrophic scarring.

Epidermis and hypodermis are two layers of the integumentary system of animals and plants. The skin of vertebrates is made of the epidermis, an external layer of epithelial tissue, and the dermis, a layer of connective tissue under the epidermis. The dermis has connective tissue, smooth muscle tissue, and nervous tissue. The epidermis is mostly made up of flat, scale-like cells called squamous cells.
