Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.

Hair follicle stem cells help skin heal and grow during stretching.

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

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

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

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

Understanding where cancer cells come from helps create better prevention and treatment methods.

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 skin cells play specific roles in development, healing, and cancer.

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

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 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.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Nail stem cells and Wnt signaling are important for fingertip regeneration but not sufficient for regenerating more complex limb structures.

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

Disrupted cholesterol production impairs hair follicle stem cells, leading to hair loss.

Lactate production is important for activating hair growth stem cells.

Lung repair involves both dedicated and flexible stem cells, important for developing new treatments.

Different types of skin cells are organized in a special way in large wounds to help with healing and hair growth.

Activating TRPV4 in skin cells helps regrow hair in mice, possibly offering a treatment for hair loss.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

miR-22, a type of microRNA, controls hair growth and its overproduction can cause hair loss, while its absence can speed up hair growth.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

Stem cells are crucial for wound healing and understanding their role could lead to new treatments, but more research is needed to answer unresolved questions.

Researchers created human hair follicles using a new method that could help treat hair loss.

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