Hair follicle stem cells can form both hair follicles and skin.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

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

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.

Different types of stem cells help maintain and heal skin.

Stromal stem cells may help heal wounds by becoming structural cells or affecting the immune system, but more research is needed to understand how.

Two-photon microscopy effectively tracks live stem cell activity in mouse skin with minimal harm and clear images.

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

Keratin protein production in cells is controlled by a complex system that changes with cell type, health, and conditions like injury or cancer.

The research found a way to identify and study skin cells with stem cell traits, revealing they behave differently in culture and questioning current stemness assessment methods.

Skin stem cells are maintained by signals from nearby cells and vary in their ability to renew and mature.

SOX9 helps determine stem cell roles by interacting with DNA and proteins that control gene activity.

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

Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.

The Foxn1(-/-) nude mouse shows disrupted and expanded skin stem cell areas due to high Lhx2 levels.

External factors can cause skin cancer cells that usually don't spread to grow and form tumors in mice.

Epidermal stem cells don't use gap junctions to communicate.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Different small areas within hair follicles send specific signals that control what type of cells stem cells become.

Age-related hair loss is linked to the decline and dysfunction of hair follicle stem cells.

Dermal fibroblasts have adjustable roles in wound healing, with specific cells promoting regeneration or scar formation.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

Aging changes sugar molecules on skin stem cells, which may affect their ability to repair skin.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

The document concludes that a protein involved in hair growth may link to baldness and that more research is needed on its role in hair loss and skin cancer treatments.

The vitamin D receptor is essential for skin stem cells to grow, move, and become different cell types needed for skin healing.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

Graying hair happens due to aging and might be delayed by new treatments.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.
