Bioactive molecules show promise for improving skin repair and regeneration by overcoming current challenges with further research.

Human hair grows better in a special gel that mimics skin.

RSPO1 mutations in certain patients lead to skin cells that don't develop properly and are more likely to become invasive, increasing the risk of skin cancer.

Fish teeth and taste bud densities are linked and can change between types due to shared genetic and molecular factors.

The document concludes that identifying the specific cells where skin cancers begin is important for creating better prevention, detection, and treatment methods.

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

Researchers developed a 3D model of human hair follicle cells that can help understand hair growth and test new hair loss treatments.

GasderminA3 is important for normal hair cycle transitions by controlling Wnt signaling.

GPR39 is linked to certain cells in the sebaceous gland and helps with skin healing.
