Certain signals are important for reducing specific chemical markers on hair follicle stem cells during rest periods, which is necessary for healthy hair growth.

IFN-γ and IL-2 are important for T cell activation in hair loss in mice.

Vav2 and Vav3 proteins help control skin stem cell numbers and activity in both healthy and cancerous cells.

Changing how mesenchymal stromal cells are grown can improve their healing abilities.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

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.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Scientists found cells in hair that are key for growth and color.

Immune cells are essential for early hair and skin development and healing.

Mint water extract boosts protective enzymes in skin cells.

Researchers developed a 3D model of human hair follicle cells that can help understand hair growth and test new hair loss treatments.

Cellular senescence has both cancer-blocking and cancer-promoting effects, and targeting senescent cells may improve health and lifespan.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

Oleoylethanolamide (OEA) safely boosts fat production in skin cells and may help treat dry skin and reduce inflammation.

Nicotinic acid reduces excessive oil production in skin cells by activating a specific receptor, which could help treat acne.

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

TGFβ's manipulation of inflammation and immune cells affects cancer spread, suggesting new treatment strategies and biomarkers.

Chemotherapy causes hair loss by damaging hair follicles and stem cells, with more research needed for prevention and treatment.

Tph cells are linked to the severity of systemic lupus erythematosus.

Innate lymphoid cells help control skin bacteria by regulating sebaceous glands.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

Older skin has higher cancer risk due to inflammation and stem cell issues.

Certain microRNAs are linked to various skin diseases and could be used to diagnose and treat these conditions.

The document concludes that immune system abnormalities cause alopecia areata, but the exact process is still not completely understood.

Contact immunotherapy can cause vitiligo in patients with autoimmune conditions.

The immune system plays a key role in tissue repair, affecting both healing quality and regenerative ability.

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

Wnt signaling is crucial for skin development and hair growth.

Nerves and chemicals in the body can affect hair growth and loss.
