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

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Auxin and ethylene hormones both work together and against each other to control plant growth.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Fat tissue-derived cells show promise for repairing body tissues, but more research and regulation are needed for safe use.

Proteins with added sugars are crucial for plant root hair growth.

YAP and TAZ are crucial for skin cell growth and repair.

Tofacitinib is safe and effective for severe alopecia areata, but hair loss may return 2 months after stopping treatment.

A genetic mutation in the LIPH gene causes hair loss and growth defects.

The hedgehog signalling pathway is key in skin development and basal cell carcinoma, offering insights for prevention and treatment.

The absence of functional sebaceous glands causes hair follicle destruction and scarring alopecia.

New effective scar treatments are urgently needed due to the current options' limited success.

Jumonji genes are important for development and their mutations can cause abnormalities, especially in the heart and brain.

The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.

Two sisters with rickets and hair loss had a genetic issue with vitamin D processing, and only improved when given phosphorus supplements.

Low-level laser therapy, now called photobiomodulation, is recognized for its broad medical applications and scientific backing.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

Follicular Unit Extraction (FUE) is a less invasive hair transplant method with minimal scarring, suitable for about 60% of patients, especially those needing fewer grafts and quicker recovery.

Congenital Adrenal Hyperplasia is a genetic disorder with two forms, causing symptoms like early puberty and severe acne, but can be identified through screening and treated with glucocorticoids.

Microneedles improve drug delivery in various body parts, are safe and painless, and show promise in cosmetology, vaccination, insulin delivery, and other medical applications.

Delta opioid receptors help regulate touch sensation by reducing neurotransmitter release in the spinal cord.

Estrogen loss during menopause worsens skin health, but hormone replacement therapy may improve it, though more research is needed.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Targeting androgen receptors could be a promising way to treat skin disorders with fewer side effects.

Mutations in three genes cause Uncombable Hair Syndrome, leading to frizzy hair that can't be combed flat.

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

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