Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Keratins are crucial for cell stability, wound healing, and cancer diagnosis.

Hair elemental analysis could be useful for health and exposure assessment but requires more standardization and research.

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

Fetal wounds heal without scarring because of different biological factors, which could help improve adult wound healing.

The study found that expanded skin regenerates similarly to normal skin, with 77 genes playing a role in the process.

Bacopa monnieri extract can significantly inhibit cell division.

RPGRIP1L helps skin cells stick together by blocking PKCβII, which can prevent skin blistering like in pemphigus.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.
