Wnt/β-catenin signaling is important for keeping skin cell attachment structures stable.

Follicular Unit Extraction (FUE) hair transplant is less invasive, leaves no scars, and has quicker recovery times, but it's more time-consuming and challenging. Automation helps speed up the process and improve graft survival, reducing the need for traditional strip surgery.

The new hair transplant device reduces damage to hair follicles and makes surgery more comfortable for the surgeon.

To prevent thinning in the donor area, harvest less than 50% of the original hair density in repeat hair transplants.

p14ARF and p16Ink4a cause hair follicle stem cell aging and dysfunction.

Surgical face-lifts are more effective, but fractional radiofrequency is a good, less invasive alternative for treating skin laxity.

Tyrosine kinases are important in skin autoimmune diseases and could be targets for new treatments.

Understanding how baby skin heals without scars could help develop treatments for adults to heal wounds without leaving scars.

Surgical robots have improved but still can't perform tasks or make decisions on their own.

Microneedles are effective for painless drug delivery and promoting wound healing and tissue regeneration.

Nanomaterials show promise in improving wound healing but require more research on their potential toxicity.

Certain immune cells contribute to skin autoimmune diseases, and some treatments can reverse hair loss in these conditions.

Microneedle technology has advanced for painless drug delivery and sensitive detection but faces a gap between experimental use and clinical needs.

Proper incision techniques can make face-lift scars less noticeable.

The document covers all aspects of plastic and reconstructive surgery, from basic techniques to specific procedures for various body parts.

Rats can't grow new hair follicles after skin wounds, unlike mice, due to differences in gene expression and response to WNT signaling.

Hair cortisol is a reliable stress indicator in cattle but may not be valid for pigs.

FUE hair transplant is a promising method with benefits like less scarring, but requires a skilled surgeon and can damage hair follicles.

There is a significant need for better-validated quality of life tools in dermatology.

SLVs help maintain muscle stretch sensitivity and could aid in treating hypertension and muscle spasticity.

When skin blisters, healing the wound is more important than growing hair, and certain stem cells mainly fix the blisters without helping hair growth.

Facial contouring is crucial for the satisfaction and well-being of Chinese transgender females.

The new hair graft device is faster, more efficient, and reduces damage to hair follicles.

A special receptor in sensory nerve endings helps control how they respond to stretching.

Special gels help heal diabetic foot sores and reduce the risk of amputation or death.

Mast cells and CD8 T cells interact closely in skin diseases, affecting each other's behavior and contributing to conditions like psoriasis and eczema.

The new wound dressing promotes cell growth and healing, absorbs wound fluids well, and is biocompatible.

Removing certain muscles during a browlift reduces glabellar wrinkles better long-term.

The review concludes that innovations in regenerative medicine, tissue engineering, and developmental biology are essential for effective tissue repair and organ transplants.

Making platelet-rich plasma gel is cheap, safe, and easy when done by trained professionals.
