Skin lesions in Carney Complex are caused by a gene change in some skin cells that leads to increased pigmentation and may lead to tumors.

EGF and FGF help hair growth by affecting cell differentiation and fiber growth.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

Different types of stem cells and their environments are key to skin repair and maintenance.

Apoptosis contributes to hair loss in androgenetic alopecia.

Cathepsin L is essential for normal hair growth and development.

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

Sebaceous glands play a key role in skin health, immunity, and various skin diseases.

Hair loss improved with treatment and successful transplant.

An 8-year-old girl had a rare, benign skin tumor on her forehead.

RANK is a key target in breast cancer treatment due to its role in tumor growth and bone metastasis.

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.

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

The document concludes that recognizing specific histological features of different nonscarring alopecias is crucial for accurate diagnosis and understanding hair loss progression.

Trichoscopy helps tell apart Frontal Fibrosing Alopecia and Lichen planopilaris by showing different hair and scalp features.

Nebivolol cream may be a promising hair loss treatment by improving blood flow and nourishing hair follicles.

Sostdc1 controls the size and number of hair and mammary gland structures.

The conclusion is that accurately identifying folliculosebaceous tumors requires understanding their clinical signs and microscopic features.

Scientists developed a way to isolate sweat glands from the scalp during hair transplants, keeping them alive for 6 days for research and cosmetic uses.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.

Epidermal stem cells help heal severe skin wounds and have potential for medical treatments.

Testosterone therapy for transmasculine individuals is generally safe with medical supervision, improves mental health, and has mixed effects on physical health.

Skin lesions in Carney complex are likely caused by a specific group of skin cells that promote pigment production due to a genetic mutation.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

Obesity affects skin health, causing conditions like acanthosis nigricans and may require different treatment approaches.

Hidradenitis suppurativa is caused by genetic factors, inflammation, bacteria, hormones, and lifestyle factors like obesity and smoking.

Fat cells are important for tissue repair and stem cell support in various body parts.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.
