Maintaining DNA health in stem cells is key to preventing aging and tissue breakdown.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Exosomes from human stem cells can help regrow hair in mice.

Removing the ATR gene in adult mice causes rapid aging and stem cell loss.

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

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

Current skin repair methods for severe burns are inadequate, but stem cells and new materials show promise for better healing.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

Different stem cells have benefits and challenges for tissue repair, and more research is needed to find the best types for each use.

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

Lower proximal cup cells, not bulge stem cells, regenerate hair follicles after chemotherapy.

The document concludes that identifying the specific cells where skin cancers begin is important for creating better prevention, detection, and treatment methods.

Aging in one type of stem cell can cause aging-like changes in various organs.

Mesenchymal stem cells and their secretions might help treat chronic skin inflammation in atopic dermatitis.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

The Wnt/β-catenin pathway can activate melanocyte stem cells and may help regenerate hair follicles.

Blood stem cells are diverse, influenced by many factors, and understanding them is key for progress in regenerative medicine.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

Certain transcription factors are key in controlling skin stem cell behavior and could impact future treatments for skin repair and hair loss.

Early and late matrix progenitors in hair follicles create different cell layers, with early ones forming the companion layer and later ones forming the inner root sheath and hair shaft.

GRHL3 is important for controlling gene activity in skin cells during different stages of their development.

Scientists developed a system to study human hair growth using skin cells, which could help understand hair development and improve skin substitutes for medical use.

Stem cell treatments can potentially treat baldness, with one trial showing hair growth after injecting a hair-stimulating complex, and no safety issues were reported.

The Hairless gene is crucial for hair cell development, affecting whether skin cells become hair or skin and oil gland cells.

Skin cysts might help advance stem cell treatments to repair skin.

Scientists found markers called CD34 and CD200 that help identify stem cells in mouse and human hair follicles.

Abnormal Wnt signaling in hair follicle stem cells can lead to acne-like cysts.

Muscle around hair follicles controls hair loss by releasing a signal that causes cell death.

MicroRNA-205 helps hair grow by changing the stiffness and contraction of hair follicle cells.
