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.

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

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

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

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

Women with PCOS and higher androgen levels are more likely to have fatty liver disease.

MIM is crucial for hair follicle formation and regeneration by controlling cilia formation and hedgehog signaling through its interaction with Cortactin and Src.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.
