Inactive hair follicle stem cells help prevent skin cancer.

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.

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

LGR5 is a common marker of hair follicle stem cells in different animals and is important for hair growth and regeneration.

Hair follicle stem cells are crucial for touch sensation and proper nerve structure in mice.

GDNF helps grow hair and heal skin wounds by acting on hair stem cells.

The circadian clock affects skin stem cell behavior, impacting aging and cancer risk.

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

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

Skin stem cells in hair follicles are important for touch sensation.

Hair follicle stem cells change states with age, affecting hair growth and aging.

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

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

Human nails and hair follicles have similar gene activity, especially in the cells that contribute to their growth and development.

GATA6 is important for maintaining and differentiating cells in a key area of human skin.

New treatments and early diagnosis methods for permanent hair loss due to scar tissue are important for managing its psychological effects.

The best way to treat acne is to prevent healthy skin glands from turning into acne lesions by controlling the triggers early on.

MED1 affects skin wound healing differently in young and old mice.

MicroRNAs are important for hair growth regulation, with Dicer being crucial and Tarbp2 less significant.

The author now believes tricholemmal carcinoma is a rare type of infundibular squamous cell carcinoma and more research is needed on these tumors.

Regulatory T cells help heal skin and grow hair, and their absence can lead to healing issues and hair loss.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

New effective scar treatments are urgently needed due to the current options' limited success.
