Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

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

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

The p75 neurotrophin receptor is important for hair follicle regression by controlling cell death.

TNF family proteins are crucial for the development of skin features like hair, teeth, and mammary glands.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Follistatin helps hair growth and cycling, while activin prevents it.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

Hormones, especially androgens, play a key role in acne, which can be a symptom of systemic diseases like PCOS and may require targeted treatment.

Macrophages are vital for skin healing, hair growth, salt balance, and cancer defense.

MRL/MpJ mice's skin wounds heal with scars, unlike their ear wounds which can regenerate.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

EGF and FGF help hair growth by affecting cell differentiation and fiber growth.

BMP6 and Wnt10b control whether hair follicles are resting or growing.

The conclusion is that small hair follicles cause baldness in macaques, and treatments like antiandrogens and minoxidil can prevent hair loss and promote regrowth.
