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.

Removing the ATR gene in adult mice causes rapid aging and stem cell loss.

Certain mature cells in mouse lungs can turn back into stem cells to aid in tissue repair.

Vitiligo is a skin condition causing white spots, more common in women, often starts before age 20, and can affect mental health.

Photobiomodulation therapy using red and near-infrared light can reduce inflammation and aid in healing various conditions.

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

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Fat-related cells are important for initiating hair growth.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

Proteasome inhibitors are promising treatments for various cancers, autoimmune diseases, and other conditions.

Improving artificial vascular grafts requires better materials and surface designs to reduce blood clotting and support blood vessel cell growth.

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

Some wound-healing cells can turn into fat cells around new hair growth in mice.

Dehydroepiandrosterone (DHEA) is a prohormone important for producing sex steroids and has potential health benefits.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

β-catenin is essential for stem cell activation and proliferation in hair follicles.

DNA profiling in forensics has improved, but predicting physical traits and ancestry from DNA has limitations and requires ethical consideration.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Auxin and ethylene hormones both work together and against each other to control plant growth.

Hair and nail cells share similar proteins, indicating a common differentiation pathway.

The nanofibers with two growth factors improved wound healing by supporting structure, preventing infection, and aiding tissue growth.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

The study found that in Latin America, ancestry varies by location, influences physical traits, and affects how people perceive their own heritage.

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.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Super-enhancers controlled by pioneer factors like SOX9 are crucial for stem cell adaptability and identity.

Changing how mesenchymal stromal cells are grown can improve their healing abilities.

Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.
