Epidermal stem cells create and maintain skin structures like hair and nails through specific signaling pathways and vary by location and function.

Scientists created complete hair-like structures by growing mouse skin cells together in a special gel.

Losing both ERBB2 and ERBB3 receptors in mice causes significant skin problems and inflammation.

The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.

Hataedock treatment improved skin health and reduced atopic dermatitis symptoms by enhancing the skin barrier and reducing inflammation.

Activating a protein called β-catenin in adult skin can make it behave like young skin, potentially helping with skin aging and hair loss.

Sebaceous glands can help harvest hair follicle stem cells to regenerate skin and hair.

The human hair follicle can store topical compounds and be targeted for drug delivery with minimal side effects.

The mTurq2-Col4a1 mouse model shows that cells can divide while attached to stable basement membranes during development.

Understanding where cancer cells come from helps create better prevention and treatment methods.

Platelet-Rich Plasma (PRP) increases the number of new hair follicles and speeds up hair formation.

Human hair has a protective lipid layer that can be damaged by moisture and treatments, affecting hair growth and health.

Involucrin helps strengthen the inner parts of human hair.

The study concluded that a protein important for hair strength is regulated by certain molecular processes and is affected by growth phases.

The research found that a specific skin cell type not only triggers hair growth but also controls hair color, and that aging can lead to hair loss and color changes.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

The book provides an overview of new trends and techniques in cosmetic dermatology.

The back of the scalp has more nerve fibers than the front, which may explain why some people feel more sensitivity there.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

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.

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

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

Restoring mitochondrial function in mice reversed their skin wrinkling and hair loss.

MicroRNAs are crucial for controlling skin development and healing by regulating genes.

Stem cells have great potential for improving wound healing, but more research is needed to find the best types and ways to use them.

Understanding how melanocyte stem cells work could lead to new treatments for hair graying and skin pigmentation disorders.

Live imaging has advanced our understanding of stem cell behavior and raised new research questions.

PI3K/Akt pathway is crucial for hair growth and regeneration.

The Ovol2-Zeb1 circuit is crucial for skin healing and hair growth by guiding cell movement and growth.
