Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Certain sugars increase in some layers of the hair follicle during the middle of the healing process in rats, which may help improve healing.

Retinoic acid can change skin structures in vertebrates, like turning scales into feathers or hair buds into glands.

Regenerative medicine could revolutionize aesthetic surgery, but needs careful validation and ethical use.
