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.

Gene therapy with the Math1 gene helped regenerate balance-related cells and improve balance in mice.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Choosing the right patients, using proper techniques, and having thorough knowledge are key to preventing and managing dermal filler complications.

Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

Fat cells in the skin help start healing and form important repair cells after injury.

MicroRNA-302 helps improve the conversion of body cells into stem cells by blocking NR2F2.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.
