Women look young for their age due to larger lips, less sun damage, and genes that prevent gray hair and wrinkles.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

Pectin biosynthesis is essential for the growth of cotton fibers and Arabidopsis root hairs.

Scientists found a new, less invasive way to study body clocks using hair cells, which shows shift workers' body clocks don't match their lifestyles.

Stem cell niches support, regulate, and coordinate stem cell functions.

Blocking JAK-STAT signaling can lead to hair growth.

Guidelines for diagnosing common hair loss include detailed history, clinical examination, and various diagnostic techniques.

Patients with certain skin symptoms and high ANA titers should be monitored for potential systemic lupus.

Trilostane effectively improved symptoms in dogs with a certain adrenal gland disorder.

Aging causes skin stem cells to work less effectively.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Obesity worsens PCOS symptoms, and PCOS may lead to more weight gain; managing both requires a holistic approach that includes mental health.

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 skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Probiotic bacteria improved skin and hair health in aged mice.

Janus kinase inhibitors are promising treatments for autoimmune skin diseases like eczema and psoriasis.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Targeting androgen receptors could be a promising way to treat skin disorders with fewer side effects.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

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.

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

People with PCOS, especially if obese, often have NAFLD, linked to obesity, insulin resistance, and high androgen levels.

Skin's Regulatory T cells are crucial for maintaining skin health and could be targeted to treat immune-related skin diseases and cancer.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Lampreys have a functional vitamin D receptor that may help detoxify harmful substances.

Restoring hair bulb immune privilege is crucial for managing alopecia areata.
