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

Certain mutations in a hair growth-related gene cause a type of genetic hair loss.

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

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

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

Telocytes might help with skin repair and regeneration.

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

Male pattern baldness involves genetics, hormones, and needs better treatments.

Effective treatments for male pattern baldness include oral finasteride and topical minoxidil, while topical minoxidil is best for female pattern baldness.

Estrogen therapy can reduce skin aging but has cancer risks.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

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

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

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 Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

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

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

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

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

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

The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

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

Microneedles help improve skin appearance and deliver skin treatments effectively, but safety concerns need more research and regulation.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

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.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Stress can stop hair growth in mice, and treatments can reverse this effect.

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.
