Genetic variation in the androgen receptor gene mainly causes early-onset hair loss, with maternal inheritance playing a key role.

Hair follicle stem cells use specific chromatin changes to control their growth and differentiation.

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

Androgens can help prevent memory problems caused by apoE4.

Minoxidil effectively lowers blood pressure with few side effects.

The conclusion is that accurate diagnosis of different types of hair loss requires good teamwork between skin doctors and lab experts.

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.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Alopecia areata causes hair loss, has no cure, and various treatments exist.

Scalp dermoscopy is good for diagnosing a type of hair loss and helps choose the best spots for biopsy.

Women with PCOS have overall higher body fat, not abnormal fat placement, and more insulin resistance.

Androgens, like testosterone, are crucial for early testicular descent in rats.

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

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

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

Nanoparticles can improve skin drug delivery but have challenges like toxicity and stability that need more research.

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.

Finasteride effectively treats baldness but may cause sexual side effects.

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.

PRP injections improve hair thickness for baldness.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

Laminin-511 is crucial for early hair growth and maintaining important hair development signals.

Scientists created stem cells that can grow hair and skin.

Trichoscopy is a useful, non-invasive way to diagnose different types of hair loss.

A wearable device using electric stimulation can significantly improve hair growth.

Alopecia areata is likely caused by a combination of genetic factors and immune system dysfunction, and may represent different diseases with various causes.

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

Cancer patients treated with immune checkpoint inhibitors may develop alopecia, but some hair regrowth is possible with treatment.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

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