Dihydrotestosterone affects hair growth by changing the Wnt/β-catenin pathway, with low levels helping and high levels hindering growth.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

Hair follicle culture helps develop new treatments for hair loss.

Collagen peptides from marine and bovine sources may help prevent hair loss by affecting hair follicle stem cells differently.

Hair follicle culture helps study hair growth but has limitations in modeling the full hair cycle.

Certain cells from hair follicles can create new hair and contribute to hair growth when implanted in mice.

New method efficiently isolates hair growth cells from newborn mouse skin.

Mice healed without scars as fetuses but developed scars as adults, suggesting scarless healing might be replicated with further research.

Two-photon microscopy effectively tracks live stem cell activity in mouse skin with minimal harm and clear images.

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

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

Electrical epilation damages hair follicles and surrounding skin, likely preventing hair regrowth.

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

Cells treated with Wnt-10b can grow hair after being transplanted into mice.

The mouse models are effective for testing new hair loss treatments.

A new method quickly and efficiently isolates hair follicle stem cells from adult mice, promoting hair growth.

Fat-derived stem cells may help treat skin aging and hair loss.

Stress can stop hair growth in mice, and treatments can reverse this effect.

Different processes create patterns in skin and things like hair and feathers.

The research found that a specific skin cell type not only triggers hair growth but also controls hair color, and that aging can lead to hair loss and color changes.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

A special mix from certain skin cells can help hair grow by making hair root cells grow faster and activating growth signals.

Inhibiting class I HDACs helps maintain hair growth ability in skin cells.

Heparan sulfate is important for hair growth, preventing new hair formation in mature skin, and controlling oil gland development.

Vitamin D3 can help improve hair growth by enhancing the function of specific skin cells and could be useful in hair regeneration treatments.

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

Cilostazol may help hair grow and could be a new treatment for hair loss.

Fgf20 is important for the development and regulation of the cells that form the base of hair follicles.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

VEGF helps hair grow and determines follicle size by increasing blood vessel growth.
