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

Apoptosis is essential for human skin development and forming a functional epidermis.

Mice lacking the PPARγ gene in their fat cells had almost no fat tissue, severe metabolic problems, and abnormal development of other fat-related tissues.

Telocytes might help with skin repair and regeneration.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Cathepsin L is essential for normal hair growth and development.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

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

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.

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

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.

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

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

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

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

Some breast cancer chemotherapy can cause permanent hair loss.

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

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

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

Certain diets can affect skin conditions, but more research is needed to understand these relationships fully.

Hair follicle hyperplasia is common in both benign and malignant skin lymphoproliferative disorders, with a proposed new term "pseudolymphomatous adnexitis."

A woman's hair loss was initially mistaken for a common hair loss condition but was later found to be caused by breast cancer cells in her scalp.

Using defensins to activate stem cells may improve skin aging signs without causing inflammation.

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

Apoptosis contributes to hair loss in androgenetic alopecia.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

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

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

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

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