Three-dimensional culture helps dermal papilla cells grow new human hair follicles.

Improving dermal papilla cells can help regenerate hair follicles.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Hair growth and development are controlled by specific signaling pathways.

Oxidative stress contributes to hair graying and loss as we age.

Certain immune cells in the skin release a protein that stops hair growth by keeping hair stem cells inactive.

Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.
