Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

Dihydrotestosterone changes some hormone-related gene expressions in rat pituitary glands but doesn't affect the estrous cycle.

An unusual growth of Leydig cells in a woman's ovaries caused her excessive hair growth, which was treated successfully with surgery.

Father's finasteride use may affect son's fertility and testicular function.

Eating less can improve stem cell function and increase lifespan.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

A thorough skin history and full examination are important for diagnosing and understanding the impact of skin diseases.

New treatments and management strategies for skin conditions like melanoma and Spitz naevi were discussed at the dermatologists' meeting.

Boosting mitochondrial energy production with supplements like acetyl-L-carnitine may improve aging-related cellular function and health conditions.

Removing Sprouty genes in mice causes various hormone-related issues but does not increase cancer risk by one year of age.

MSC-protein helps regenerate gum tissue and bone.

A specific enzyme is essential for proper hair follicle stem cell development and healthy skin.

Aged individuals heal wounds less effectively due to specific immune cell issues.

People with Down syndrome have higher rates of certain immune-related conditions and need special medical attention.

Scientists made a mouse that shows how a specific protein in the skin changes and affects hair growth and shape.

Vav2 changes how hair follicle stem cells' genes work as they age, which might improve regeneration but also raise cancer risk.

Sweat gland development involves two unique skin cell programs and a temporary skin environment.

A 24-year-old woman had a rare ovarian tumor that caused male-pattern hair growth and was hard to diagnose and treat.

A young woman had a rare, aggressive ovarian tumor that was hard to diagnose and treat, leading to disease progression despite treatment.

Leucaena feed helps farmers grow larger cattle herds and is good for fattening, but its safety for breeding cows is unclear.

Increasing Rps14 helps grow more inner ear cells and repair hearing cells in baby mice.

Gene therapy in mice increased lifespan and improved health without causing cancer.

Removing a specific gene in certain skin cells causes hair loss on the body by disrupting normal hair development.

Researchers found that certain RNA sequences play a role in yak hair growth and these sequences are somewhat similar to those in cashmere goats.

The study found that certain genes are important for hedgehog skin appendage development and immunity, with spines possibly evolving for protection and infection resistance.

Researchers found four key stages of cell development that are important for hair growth and shedding in cashmere goats.

Suppressing very long chain fatty acids is linked to skin cancer.

Semecarpus anacardium leaf extracts may offer safe, effective cancer treatment alternatives.

The trial will test if YH0618 granule prevents hair loss in breast cancer patients during chemotherapy.

Proretinal nanoparticles are a safe and effective way to deliver retinal to the skin.
