In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Fat-related cells are important for initiating hair growth.

Epidermal stem cells are crucial for skin health and problems with them can cause issues like poor wound healing, cancer, and aging.

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

Researchers created rat liver stem cells that could help repair liver failure in rats and may be useful for studying human liver diseases.

Scientists created a long-lasting stem cell line from human hair that can turn into different skin and hair cell types.

Hair samples can be used to create stem cells easily and non-invasively.

Scientists created MUSIi010-A, a stem cell line from a balding man's scalp, to study hair loss and develop potential treatments.

Vitamin A helps skin stem cells decide their function, aiding in hair growth and wound repair.

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

Androgen is important in controlling stem cell differentiation, reducing fat development, and increasing lean mass.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.

Skin cell behavior is influenced by the tightness of nearby cells, affecting their growth and development.

Wounded skin cells can revert to stem cells and help heal.

Stem cells in hair follicles can become various cell types, including neurons.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

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

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Rat whisker cells can help turn other cells into nerve cells and might be used to treat brain injuries or diseases.

Myc activation reduces skin stem cells by affecting cell adhesion.

Mammary stem cells drive mammary gland growth by branching and cell mixing.

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

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

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

A specific group of skin stem cells was found to help maintain hair follicle cells.

The study suggests that motor neurons created from stem cells of patients with spinal and bulbar muscular atrophy show signs of the disease, including changes in protein levels and cell functions.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

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.

Newly found stem cells in horse hooves show promise for treating a hoof disease called laminitis.
