Metabolic signals and cell shape influence how cells develop and change.

Dihydrotestosterone (DHT) mainly affects nearby cells, doesn't significantly change prostate hormonal environment or cancer risk, and doesn't play a main role in causing hair loss or acne. More research is needed on its effects on heart health, sexual function, and bone health.

Long-term use of finasteride in women can cause hormonal changes, DNA damage, and menstrual issues.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

Sweat hypersensitivity can cause severe skin issues in horses.

Type 2 diabetes slows down skin and hair renewal by blocking important stem cell activation in mice.

Swedish men with the E213 A-allele of the androgen receptor have a lower risk of prostate cancer.

Hair ages due to genetics and environmental factors, leading to graying and thinning, with treatments available for some conditions.

New treatments for skin diseases are more effective and patient-friendly, but many still lack a cure.

The document concludes that understanding how hair follicles naturally die and regenerate is important for insights into organ development and could impact health and disease treatment.

Hdac1 and Hdac2 help maintain and protect the cells that control hair growth.

The skin's dermal layer contains true stem cells with diverse functions and interactions that need more research to fully understand.

The study found that stem cells and neutrophils are important for regenerating hair follicle structures in mice.

Effective treatments for male pattern baldness include oral finasteride and topical minoxidil, while topical minoxidil is best for female pattern baldness.

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

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Sensitive skin is often caused by nerve fibers and environmental factors, and can be managed with mild skincare and professional advice.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Blocking Wnt signaling in young mice causes thymus shrinkage and cell loss, but recovery is possible when the block is removed.

Finasteride reduces hair loss and treats BPH without major hormone changes, but may cause sexual dysfunction.

Skin tumor regression is helped by retinoic acid signaling blocking Wnt signaling.

Different treatments for alopecia areata have varying success rates and side effects; intralesional steroids are most effective.

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

PBX1 helps hair stem cells grow and change by turning on certain cell signals and preventing cell death, which may be useful for hair regrowth treatments.

Using microneedles before applying eflornithine cream can make it more effective at stopping hair growth.

New physical methods like electrical currents, ultrasound, and microneedles show promise for improving drug delivery through the skin.

Keratoacanthoma comes from hair follicle cells.

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

Stress hormones like cortisol may trigger psoriasis flare-ups.

Finasteride and dutasteride are effective for long-term treatment of enlarged prostates but have sexual side effects and a risk of high-grade prostate cancer.
