Certain genes are more active during wound healing in axolotl and Acomys, which could help develop materials that improve human wound healing and regeneration.

New tools show that in fish, NPY increases feeding and somatostatin decreases it.

Different types of skin on mice have unique chemical profiles related to how they grow and react to stress.

Androgenetic alopecia, or hair loss, is caused by a mix of genetics, hormones, and environment, where testosterone affects hair growth and causes hair to become smaller and grow for a shorter time.

Oral and topical finasteride are effective and safe for treating female hair loss.

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Different types of inactive melanocyte stem cells exist with unique characteristics and potential to develop into other cells.

Different types of resting melanocyte stem cells have unique characteristics and vary in their potential to become other cells.

The method allows for 3D tracking of hair follicle stem cells and shows they can regenerate hair for up to 180 days.

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

Skin lesions in Carney complex are likely caused by a specific group of skin cells that promote pigment production due to a genetic mutation.

Nestin identifies specific progenitor cells in hair follicles that can become outer root sheath cells.

Activating β-catenin increases melanocytes and decreases Schwann cells.

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

Skin lesions in Carney Complex are caused by a gene change in some skin cells that leads to increased pigmentation and may lead to tumors.

New treatments like nanotechnology show promise in improving skin cancer therapy.

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

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

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

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

A specific group of slow-growing stem cells marked by Thy1 is crucial for skin maintenance and healing in mice.

Skin healing from blisters can delay hair growth as stem cells focus on repairing skin over developing hair.

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

New methods have greatly improved our understanding of stem cell behavior and roles in the body.

Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

T-cell reconstitution after thymus transplantation can cause hair whitening and loss.

Turning scar-forming cells into fat cells can reduce scarring.

African spiny mice can regenerate skin, hair, and cartilage, but not muscle, and their unique abilities could be useful for regenerative medicine.

The research reveals how early embryonic mouse skin develops from simple to complex structures, identifying various cell types and their roles in this process.
