Prostate cancer cells can make their own androgens to activate the androgen receptor, and treatments like abiraterone may increase this ability, suggesting new therapies should target the entire steroid-making pathway.

Minoxidil boosts hair growth by opening potassium channels and increasing cell activity.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

β-catenin is essential for stem cell activation and proliferation in hair follicles.

DNA profiling in forensics has improved, but predicting physical traits and ancestry from DNA has limitations and requires ethical consideration.

Stress can worsen skin and hair conditions by affecting the skin's immune response and hormone levels.

Myo-inositol supplements may improve insulin sensitivity and help with conditions like PCOS and gestational diabetes, but more research is needed.

Auxin and ethylene hormones both work together and against each other to control plant growth.

Hair and nail cells share similar proteins, indicating a common differentiation pathway.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Metformin helps with menstrual cycles and insulin levels in PCOS but is less effective for hair growth, diabetes prevention, and weight loss, and may improve fertility and reduce diabetes risk.

Calreticulin has roles in healing, immune response, and disease beyond its known functions in the endoplasmic reticulum.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Fat tissue-derived cells show promise for repairing body tissues, but more research and regulation are needed for safe use.

The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

The document concludes that the understanding of scar formation is incomplete and current prevention and treatment for hypertrophic scars and keloids are not fully effective.

Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

The conclusion is that certain cell interactions and signals are crucial for hair growth and regeneration.

Air pollution worsens skin diseases and aging by causing inflammation and oxidative stress.

Stromal stem cells may help heal wounds by becoming structural cells or affecting the immune system, but more research is needed to understand how.

The conclusion is that using drugs to block the TOR pathway might slow aging and prevent age-related diseases.

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

Adult stem cells from rat whisker follicles can regenerate hair follicles and sebaceous glands.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

Removing part of the vitamin D receptor stops vitamin D from working properly.

Vitamin D receptor interacts with certain dietary components to help prevent diseases and regulate hair growth.

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

New nanofiber technology improves wound healing by supporting cell growth and delivering treatments directly to the wound.
