Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

New effective scar treatments are urgently needed due to the current options' limited success.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

Humans lost body hair relatively recently in evolution.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

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.

Hibiscus plant extracts may have health benefits like lowering blood pressure and protecting the heart.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

Fibroblast growth factor receptor signaling controls cell development and repair, and its malfunction can cause disorders and cancer, but it also offers potential for targeted therapies.

Wnt and Notch signaling help wound healing by promoting cell growth and regulating cell differentiation.

Applying a special compound can promote hair growth without harmful side effects.

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

Fetal wound healing changes with development, affecting inflammation and collagen, which may influence scarring.

New treatments for Alopecia Areata show promise but need to be more effective and affordable.

New nanocomposites with copper show promise for healing burn wounds and regenerating skin.

The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.

Wnt signaling helps control how brain stem cells divide and is important for brain repair after injury.

The Wnt/β-catenin pathway is important for tissue development and has potential in regenerative medicine, but requires more research for therapeutic use.

Mice studies show that Protein Phosphatase 2A is crucial for cell growth, development, and disease prevention.

Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.

Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.

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