The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

Fat cells help recruit healing cells and build skin structure during wound healing.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

After menopause, women lose a lot of skin collagen, but estrogen replacement might improve skin health.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

Skin grafts are effective for chronic leg ulcers, especially autologous split-thickness grafts for venous ulcers, but more data is needed for diabetic ulcers.

Botulinum toxin shows promise for various skin conditions but requires more research for confirmation and standardized use.

Menopause significantly reduces skin collagen, leading to thinner, less elastic skin, and hormone replacement may help but requires careful consideration.

Thyroid hormone affects skin health, with too little causing rough, pale skin and too much leading to smooth, thin skin, and may also impact wound healing and skin conditions.

A special hydrogel helps heal skin without scars and regrows hair.

Leaving non-absorbable sutures in for 6 months reduces scar stretching and width.

Disrupting Notch signaling in blood vessels increases scarring during wound healing in mice.

The African spiny mouse can fully regenerate its muscle without scarring, unlike the common house mouse.

The shape of fibrous scaffolds can improve how stem cells help heal skin.

Thyroid hormones affect skin texture, hair and nail growth, and can cause skin diseases related to thyroid problems.

Wnt1a helps keep cells that can grow hair effective for potential hair loss treatments.

New physical methods like electrical currents, ultrasound, and microneedles show promise for improving drug delivery through the skin.

Hair follicle stem cells are promising for wound healing but require more research for safe clinical use.

New gel formulas without ethanol and propylene glycol, containing a minoxidil-methyl-β-cyclodextrin complex, have been created for treating hair loss.

Dermatologists play a key role in identifying and documenting signs of abuse and injury for forensic investigations.

Platelet-Rich Plasma (PRP) could potentially help regrow hair in people with Alopecia Areata, but more research is needed to confirm its effectiveness.

Lasers in hair transplantation may have potential but require caution due to possible damage and reduced graft survival.

Adding stem cells to fat grafts for facial rejuvenation might improve outcomes, but more research is needed to confirm safety and effectiveness.

Minoxidil can cause allergic skin reactions in some users.

Mouse stem cells from hair follicles can improve wound healing and reduce scarring.

Vacuum massage may improve skin elasticity and induce changes in skin cells, but evidence for treating burn scars is insufficient and more research is needed.

Targeting the actin cytoskeleton could improve skin healing and reduce scarring.

Island grafts can help study skin regeneration separately from other healing processes.
