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.

Endocannabinoids help control mast cell activity in human skin.

Skin aging is a complex process influenced by various factors, leading to wrinkles and sagging, and should be considered a disease due to its health impacts.

Platelet-rich plasma (PRP) is a cheap and easy treatment for hair loss, but not suitable for everyone. It also helps in healing ulcers, rejuvenating skin, and improving hair transplants.

Scarless healing is complex and influenced by genetics and environment, while better understanding could improve scar treatment.

Skin fat helps with body temperature control and has other active roles in health.

Shrinking skin cancer increases the chance of cancer in nearby lymph nodes.

Using your own skin cells can help repair aging skin and promote hair growth.

Wnt signaling is crucial for skin wound healing and reducing scars.
