Mouse cell exosomes help hair regrowth and wound healing by activating a specific signaling pathway.

Lef1 is essential for normal skin, hair growth, and healing wounds in mice.

Newborn skin cells can change into wound-healing cells more easily than adult ones, which might explain why baby skin heals without scars. Understanding this could help treat chronic wounds and prevent scarring.

Different types of sun exposure can damage skin cells and affect healing, with chronic exposure being more harmful, and certain immune cells help in the repair process.

A 9-month-old baby had a rare, persistent ring-shaped hair loss condition.

Scientists found a new method using 3D cell cultures to grow human hair which may improve hair restoration treatments.

The technique can potentially treat hair loss by using a matrix to grow new hair from cells.

Certain human skin cells marked by CD44 and ALDH are rich in stem cells capable of long-term skin renewal.

Certain zinc transporters are essential for healthy skin and managing zinc in the body could help treat skin problems.

Different types of alopecia in children require specific diagnoses and treatments.

Researchers developed a new skin patch that delivers more finasteride into the skin, potentially improving treatment for hair loss and prostate issues.

Children with partial biotinidase deficiency are healthy at birth but may develop symptoms that improve with biotin therapy.

The human skin's outer layer has more variety in cell types and development paths than previously thought.

Using CDK inhibitors on rats showed a reduction in chemotherapy-caused hair loss, but later experiments could not repeat these results.

Blocking β-catenin in skin cells improves hair growth during wound healing.

Sox2-positive dermal papilla cells have unique characteristics and contribute more to skin and hair follicle formation than Sox2-negative cells.

Chickens exposed to loud noise can quickly regain hearing mostly due to repair of the tectorial membrane, not just hair cell regeneration.

CYP2B12 enzyme in skin cells converts arachidonic acid into specific bioactive lipids.

Two enzyme defects in biotin metabolism cause severe skin, hair, and metabolic issues.

TAF4 is important for skin cell growth and helps prevent skin cancer in mice.

Follistatin and LIN28B together improve the ability of inner ear cells in mice to regenerate into hearing cells.

AHCC reduces hair loss and liver injury caused by chemotherapy in rodents.

Activin B helps start and grow hair follicles in mice.

Multi-peptide factors from fibroblasts may stimulate hair growth by increasing growth factors and β-catenin in hair cells.

The research found ways to activate melanocyte stem cells for potential treatment of skin depigmentation conditions.

Modifying certain signals in the body can help wounds heal without scars and regrow hair.

The method can test hair growth products using a lab-made hair-like structure that responds to known treatments.

Early NAS level changes affect alcohol consumption vulnerability.

Boosting HGF signaling could improve the creation of hair follicles in lab-made skin.

The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.
