High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Hairless protein can block vitamin D activation in skin cells.

Scientists found a specific group of itch-sensing nerve cells in mice important for feeling itch but not for sensing heat or touch.

Cetaceans lost hair due to changes in the Hr and FGF5 genes.

Cidea is essential for proper lipid storage and secretion in sebaceous glands, affecting skin and hair health.

The rhg mutation in mice affects the Oat gene, causing hair growth issues and other symptoms.

Lung and liver macrophages protect our tissues and their dysfunction can cause various diseases.

Microneedles are promising for long-acting drug delivery and can improve patient compliance, but more data is needed to confirm their effectiveness.

Finasteride may lower cholesterol and slow heart disease progression.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.

More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.

ATP-dependent chromatin-remodeling complexes are crucial for gene regulation, cell differentiation, and organ development in mammals.

Hair follicles may soon be used more for targeted and systemic drug delivery.

Scientists created stem cells that can grow hair and skin.

Conditioned media from mesenchymal stem cell cultures could be a more effective alternative for regenerative therapies, but more research is needed.
