The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Stem cells can help regenerate hair follicles.

KY19382 helps regrow hair and create new hair follicles.

The patch assay can create mature hair follicles from human cells and may help in hair loss treatments.

Hair follicle regeneration is possible but challenging, especially in humans, due to the need for specific cells and a better understanding of how they signal growth.

Activin A is important for creating new hair follicles.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

The conclusion is that certain cell interactions and signals are crucial for hair growth and regeneration.

Hair follicles help absorb and store topical compounds, aiding targeted drug delivery.

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

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.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

Blocking β-catenin in skin cells improves hair growth during wound healing.

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

Skin problems can be caused or worsened by physical forces and pressure on the skin.

Technique creates 3D cell spheroids for hair-follicle regeneration.

Epidermal stem cells could lead to new treatments for skin and hair disorders.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

Maintaining the right amount of retinoic acid is crucial for healthy hair and skin.

Hair follicle stem cells could help repair nerves and avoid ethical issues linked to embryonic stem cells.

Hair follicles offer promising targets for delivering drugs to treat hair and skin conditions.

Vitamin D3 analogs can promote hair growth in mice genetically prone to hair loss.

Stem cell therapy may help treat tough hair loss cases.

Hair follicle stem cells can turn into various cell types and help repair nerves.

Transit-amplifying cells are crucial for tissue repair and can contribute to cancer when they malfunction.

Prominin-1 expressing cells in the dermal papilla help regulate hair follicle size and communication but don't aid in skin repair.

Radiation mainly affects keratinocyte stem cells, not melanocyte stem cells, causing hair to gray.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.
