Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Male hormones may play a role in the development of heart disease, and more research is needed to understand their effects.

The vitamin D receptor is involved in multiple body functions beyond calcium regulation, including immune response and rapid reactions not related to gene activity.

Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.

The Rotterdam Study found risk factors for elderly diseases, links between lifestyle and genetics with health conditions, and aimed to explore new areas like DNA methylation and sensory input effects on brain function.

The conclusion is that certain cell interactions and signals are crucial for hair growth and regeneration.

The Rotterdam Study aims to understand disease causes in the elderly and has found new risk factors and genetic influences on various conditions.

PCOS is a complex disorder in women that can lead to various health risks and requires personalized treatment.

Iron deficiency may be related to hair loss, but there's not enough evidence to recommend iron screening or supplements for all hair loss patients.

ATP-dependent chromatin-remodeling complexes are crucial for gene regulation, cell differentiation, and organ development in mammals.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

The document concludes that recognizing and treating cutaneous lupus erythematosus early is crucial for managing the skin and potential systemic symptoms.

Humans lost body hair relatively recently in evolution.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

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.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

Testosterone's muscle-building effects do not require its conversion to DHT.

TSH is usually the only test needed to check thyroid function in primary care.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Choosing the right model order in brain connectivity analysis can affect the detection of differences between healthy individuals and those with seasonal affective disorder.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Turing patterns are now recognized as important in developmental biology.

Blocking β-catenin in skin cells improves hair growth during wound healing.

Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Animal models have helped understand hair loss from alopecia areata and find new treatments.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Progress has been made in skin and nerve regeneration, but more research is needed to improve methods and ensure safety.
