People with alopecia areata have more Th17 cells and fewer Treg cells, which may be key to the condition's development.

Hormones during pregnancy and lactation keep skin stem cells inactive, preventing hair growth.

Androgen is important in controlling stem cell differentiation, reducing fat development, and increasing lean mass.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

Different types of fibroblasts play specific roles in wound healing and cancer, which could help improve treatments.

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

Androgens may influence T cells, contributing to higher autoimmune liver disease risk in women.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

Diffuse alopecia areata involves more inflammation and higher allergy-related antibodies than patchy types.

Children with autoimmune gastritis showed improved intestinal health over time and should be checked for other autoimmune conditions.

Removing the ATR gene in adult mice causes rapid aging and stem cell loss.

Fat-related cells are important for initiating hair growth.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

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

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like 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.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Skin's Regulatory T cells are crucial for maintaining skin health and could be targeted to treat immune-related skin diseases and cancer.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

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

Patients with Alopecia areata have fewer specific immune cells that normally regulate the immune system, which may contribute to the condition.

Regulatory T cells are essential for normal and improved wound healing in mice.

Different markers are found in stem cells of the scalp's hair follicle bulge and the surrounding skin.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Treg dysfunction is linked to various autoimmune skin diseases, and understanding Treg properties is key for new treatments.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.
