Ovarian stromal hyperplasia can cause high testosterone in postmenopausal women and is treated by removing the ovaries.

Aging skin shows thinner layers, fewer hair follicles, and new biomarkers like increased space between cells and smaller sebaceous glands.

Thymic stromal lymphopoietin (TSLP) promotes hair growth, especially after skin injury.

Sorafenib is effective in treating Desmoid Tumor/Deep Fibromatosis.

The research found that MRI and certain hormone levels can help tell apart ovarian tumors from hyperthecosis in postmenopausal women, but tissue analysis is still needed for a definite diagnosis.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

RANKL causes lymph nodes to grow by making certain cells multiply.

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.

SACUMAN, a rare condition causing hair loss without clear signs, is often misdiagnosed and needs scalp biopsies for accurate detection.

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

CREB, a protein that can promote cancer traits, is controlled by β-catenin in skin cancer cells.

Lack of sleep in mice leads to prostatitis by reducing certain hormones and activating an inflammatory pathway, which can be temporarily fixed with normal sleep.

Testosterone therapy seems safe and effective for transgender men with proper care, but more long-term research is needed.

The Wnt signaling pathway is not a major factor in the development of keratoacanthoma, a type of skin tumor.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Adult hair follicle cells can create new hair follicles from corneal cells with the right support.

A man had rare skin tumors with bone formation and cholesterol deposits.

The document concludes that ERBB2 mutations are common in extramammary Paget disease and may respond to systemic treatments like cancer immunotherapy.

Different types of skin cells play specific roles in development, healing, and cancer.

Eph/ephrin signaling is important for skin cell behavior and could be targeted to treat skin diseases.

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

The drug combination was safe and showed promise in treating advanced tumors.

Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.

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

Innate lymphoid cells help control skin bacteria by regulating sebaceous glands.

Exosome treatment safely increases hair density in male patients with androgenetic alopecia.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Scalp biopsies from dermatomyositis patients show chronic hair loss without scarring, with mucin and blood vessel changes being very common.

A woman had a unique skin growth with hair follicle, oil glands, fat cells, spindle cells, and nerve fibers.
