Finasteride effectively treats BPH, but needs more trials to understand potential.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

Hair follicle development and microbes help regulatory T cells gather in newborn skin.

Hair loss needs more research for better treatments.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.

Male hormones, particularly DHT, are linked to male pattern hair loss, and treatments like finasteride can help, but they don't work for postmenopausal women's hair loss, which may have different causes.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Androgens can cause hair growth in some areas and hair loss on the scalp.

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

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

Androgens, like testosterone, are crucial for early testicular descent in rats.

Transplant success has improved with better immunosuppressive drugs and donor matching.

Understanding hair follicle anatomy helps diagnose hair disorders.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

Finasteride and minoxidil are effective for hair regrowth, while treatments for alopecia areata have varying success and continuous treatment is necessary.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.

Hair, teeth, and mammary glands develop similarly at first but use different genes later.

Minoxidil is the only FDA-approved topical drug for treating male or female pattern hair loss, and other medications like finasteride and dutasteride can also increase hair growth.

Skin-derived precursors in hair follicles come from different origins but function similarly.

Finasteride doesn't harm male fertility or sperm quality, but may slightly reduce ejaculate volume.

Finasteride effectively blocks rat enzymes, but with varying methods and strength.

Hair elemental analysis could be useful for health and exposure assessment but requires more standardization and research.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.
