The exact identity of skin stem cells and how skin cells differentiate is not fully known.

The gene Tfap2b is essential for creating a type of stem cell in zebrafish that can become different pigment cells.

Removing a specific gene in certain skin cells causes hair loss on the body by disrupting normal hair development.

Activin A increases inner ear hair cell development, while follistatin decreases it.

Myoepithelial cells can repair airways after severe injury.

Older hair follicle stem cells have a reduced ability to renew themselves, leading to more hair loss.

Obesity can weaken the skin's ability to fight infections because fat cells stop and reduce the infection-fighting properties of nearby stem cells.

Activating Nrf2 helps wounds heal faster by increasing hair follicle stem cells.

ATP-dependent chromatin remodeling is crucial for skin development and stem cell function.

Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

The study found that sweat glands normally suppress immune responses, but this is disrupted in certain skin diseases, possibly contributing to their development.

Researchers improved a method to study individual cells in newborn mouse skin and found a way to assess the severity of a skin condition in humans.

Blood cells turned into stem cells can become skin cells similar to normal ones, potentially helping in skin therapies.

Human hair follicle cells can be turned into stem cells that may help clone hair for treating hair loss or burns.

Skin stem cells are crucial for maintaining and repairing skin, with potential for treating skin disorders and improving wound healing.

Fat-derived stem cells may help treat skin aging and hair loss.

Low-level laser therapy may help stem cells grow and function better, aiding in healing and tissue repair.

The conclusion is that grasping how cells determine their roles through evolution is key, with expected progress from new research models and genome editing.

Fat-derived stem cells and their secretions show promise for treating skin aging and hair loss.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

Ovol2 is crucial for hair growth and skin healing by controlling cell movement and growth.

Stem cells can create hair follicles, potentially treating permanent hair loss, and healthy skin and hair depend on mitochondrial function and special fats.

Hair loss in Androgenetic Alopecia is not caused by damage to follicular stem cells.

The secretions of mesenchymal stem cells could be used for healing without using the cells themselves.

Changing how mesenchymal stromal cells are grown can improve their healing abilities.

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

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

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.

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.

Aging causes skin stem cells to work less effectively.
