Pattern hair loss is mainly caused by genetics and hormones, with limited effective treatments available.

Epigenetic factors play a crucial role in skin health and disease.

Feather patterns form through genetic and epigenetic controls, with cells self-organizing into periodic patterns.

The model accurately predicts age from saliva and buccal cells for forensic use.

Changes in KRT17 gene activity linked to wool production in Angora rabbits.

A special gene region controls the re-emergence of a primitive wool type in Merino sheep, improving their wool yield and adaptability.

American men are older, more obese, and have longer infertility than Canadian men.

The document concludes that future heart disease research should account for sex-specific differences to improve diagnosis, treatment, and outcomes.

Men and women respond differently to drugs for COVID-19, high cholesterol, and diabetes, which suggests a need for personalized treatments.

Tissue environment greatly affects the unique epigenetic makeup of regulatory T cells, which could impact autoimmune disease treatment.

Human hair proteins vary by individual, body site, and ethnicity, useful for forensics.

Men are more likely to have severe respiratory viral infections like COVID-19 due to hormonal and genetic differences, while women generally have stronger immune responses.

Mothers have more hair proteins than their children, with age-related differences in protein patterns, and some proteins in hair could indicate early childhood development.

A mother's diet at conception can cause lasting genetic changes in her child.

The document concludes that understanding hair follicle cell cycles is crucial for hair growth and alopecia research, and recommends specific techniques and future research directions.

The document concludes that there is a significant lack of reporting on the sex and age of cells in skin research, which could affect clinical trials and treatments.

Chromosomal differences affect how muscle cells respond to testosterone.

Aging causes sweat glands to shrink, leading to skin issues, and blue light can help hair grow.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Androgens are important for normal ovarian function and estrogen production, but may not be the main cause of follicle death.

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

Valproic Acid could potentially be used to treat immune-related conditions due to its ability to modify immune cell functions.

High levels of androgens during early development may cause PCOS-like symptoms.

Certain signals are important for reducing specific chemical markers on hair follicle stem cells during rest periods, which is necessary for healthy hair growth.

Gonadal hormones significantly affect the severity of alopecia areata in mice.

DNA methylation changes are linked to hair growth cycles in goats.

Skin aging is caused by stem cell damage and can potentially be delayed with treatments like antioxidants and stem cell therapy.

Different processes create patterns in skin and things like hair and feathers.

Genetic research has advanced our understanding of skin diseases, but complex conditions require an integrative approach for deeper insight.
