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.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

The research found a way to identify and study skin cells with stem cell traits, revealing they behave differently in culture and questioning current stemness assessment methods.

Alkaline Ceramidase 1 prevents early hair loss in mice by keeping hair follicle stem cells balanced.

Hair follicle stem cells from Arbas Cashmere goats can become fat, nerve, and liver cells.

Abdominal skin heals faster than dorsal skin because it has more stem cells.

RANK-RANKL signaling is essential for hair growth and skin health.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.

Epidermal stem cells create and maintain skin structures like hair and nails through specific signaling pathways and vary by location and function.

Different human hair follicle stem cells grow at different rates and respond differently to a baldness-related compound.

Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.

Prominin-1 expressing cells in the dermal papilla help regulate hair follicle size and communication but don't aid in skin repair.

Hair follicle stem cells are controlled by their surrounding environment.

When skin blisters, healing the wound is more important than growing hair, and certain stem cells mainly fix the blisters without helping hair growth.

Lack of Ctip2 in skin cells delays wound healing and disrupts hair follicle stem cell markers in mice.

Epidermal growth factor helps stem cells heal wounds and regenerate hair follicles faster.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

A specific enzyme is essential for proper hair follicle stem cell development and healthy skin.

Different types of skin cells play specific roles in development, healing, and cancer.

N-acetyl-L-cysteine (NAC) can prevent DNA damage and protect cells from harm.

A protein called desmoglein 3 is important for keeping hair follicle stem cells inactive and helps in their regeneration.

Hdac1 and Hdac2 help maintain and protect the cells that control hair growth.

Scientists made structures that look like human hair follicles using stem cells, which could help grow hair without using actual human tissue.

Blocking specific proteins can help remove aging cells and might treat age-related diseases and promote hair growth.

Graying hair happens due to aging and might be delayed by new treatments.

Dermal Wnt/β-catenin signaling is important for the proper size and development of hair follicles.

The hair follicle is a great model for research to improve hair growth treatments.

The document concludes that understanding hair and feather regeneration can help develop new regenerative medicine strategies.

Wnt10b makes hair follicles bigger, but DKK1 can reverse this effect.
