Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

Human hair follicles can regenerate after removal, but with low success rate.

The document explains how the male reproductive system works, its role in making testosterone, and how conditions like obesity can disrupt it, leading to low testosterone and fertility issues.

Cancer can hijack the body's cell repair system to promote tumor growth, and targeting this process may improve cancer treatments.

The document concludes that targeting the androgen receptor may be a promising breast cancer treatment, especially for certain types.

Inactive hair follicle stem cells help prevent skin cancer.

Androgen receptors are key for development and health, affecting conditions like prostate cancer and male pattern baldness.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

Myo-inositol helps improve skin conditions and metabolic profiles in young women with PCOS.

Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Sunlight worsens hair loss; protect scalp.

Nanotechnology in dermatology shows promise for better drug delivery and treatment effectiveness but requires more safety research.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

Both mouse and rat models are effective for testing alopecia areata treatments.

Products should be called 'sperm-safe' only after thorough, well-designed tests.

Hair loss can indicate underlying systemic diseases and addressing these can sometimes reverse the hair loss.

Researchers found 71 genetic regions linked to male pattern baldness, which account for 38% of its genetic risk.

Key genes are crucial for Drosophila wing development and could be insecticide targets.

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

Different women's hair and skin glands respond to hormones in varied ways, which can cause unwanted hair growth even with normal hormone levels, and more research is needed to treat this effectively.

Wnt, Eda, and Shh pathways are crucial for different stages of sweat gland development in mice.

Tcf3 helps cells move and heal wounds by controlling lipocalin 2.

Skin bacteria, specifically Staphylococcus aureus, help in wound healing and hair growth by using IL-1β signaling. Using antibiotics on skin wounds can slow down this natural healing process.

Cancer treatments often cause hair disorders, significantly affecting patients' quality of life, and better management methods are needed.

IGF-1 injections help mice grow more hair by increasing cell growth and blocking a hair growth inhibitor.

Some medications can cause acne, and stopping these drugs is the main treatment.

Botox increased hair count in men with baldness and might work by improving scalp blood flow.

The protein StAR is found in 17 different organs and can affect hair loss and brain functions, but its full role is not yet fully understood.

Wnt signaling is important for development and cell regulation but can cause diseases like cancer when not working properly.
