The circadian clock influences the behavior and regeneration of stem cells in the body.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

Scientists have made progress in growing mini-organs and regenerating parts of the skin, with plans to treat hair loss in a future trial.

The "Two-Cell Assemblage" assay is a new, simple method to identify substances that may promote hair growth.

Growing human skin cells in a 3D environment can stimulate new hair growth.

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.

The document concludes that careful evaluation is key to diagnose and treat women with hair loss, with tests for thyroid, iron, and hormones as needed.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Hair growth and health are influenced by factors like age, environment, and nutrition, and are controlled by various molecular pathways. Red light can promote hair growth, and understanding these processes can help treat hair-related diseases.

Only skin melanocytes, not other types, can color hair in mice.

PGD2 stops hair growth and is higher in bald men with AGA.

Short telomeres contribute to aging and cancer, and while telomerase can delay aging, it may also promote cancer.

Family members of North Indian women with PCOS have a high rate of metabolic syndrome.

Androgens like testosterone are important hormones for both men and women, made differently in each sex and affecting the body by regulating genes and quick interactions with cell components.

Scientists have made progress in creating replacement teeth, hair, and glands that work, which could lead to new treatments for missing teeth, baldness, and dryness conditions.

Women with PCOS have a higher risk of metabolic syndrome and need lifestyle changes and treatment.

Canine epidermal neural crest stem cells could be a promising treatment for spinal cord injuries in dogs.

Stem cell differentiation is crucial for skin barrier maintenance and its disruption can lead to skin diseases.

Caffeic acid helps protect rats from the harmful effects of acrylamide.

Caraway, Chinese chives, and cassia may improve health and prevent diseases due to their nutrients and medicinal properties.

HNG may help prevent the negative effects of chemotherapy on sperm production and white blood cell counts.

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.

Lower levels of certain genes in hair cells improve hair loss treatment outcomes.

Gamma delta T cells in the skin help with healing and defense but can also cause autoimmune issues, and more research is needed to understand how they are activated.

Tissue engineering could be a future solution for hair loss, but it's currently expensive, complex, and hard to apply in real-world treatments.

Hair follicles are essential for skin health, aiding in hair growth, wound healing, and immune function.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

Sex hormones, especially estradiol, can change chicken feather shapes and colors.

Epimedium extract helps increase skin pigmentation and could be a new treatment for conditions with reduced pigmentation.
