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

Notch signalling helps skin cells differentiate and prevents tumors.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Keratin 79 marks a new group of cells that are key for creating and repairing the hair follicle's structure.

Pollution increases a compound in the skin that can lead to faster aging and more inflammation.

LEF1 interacts with Vitamin D Receptor, affecting hair follicle regeneration and this could be linked to hair loss conditions.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

Laminin 332 is essential for normal skin cell behavior and structure.

Intermediate filaments are crucial for cell differentiation and stem cell function.

The document concludes that stem cell inactivity is actively controlled and important for tissue repair and balance.

Hair dye ingredient PPD causes cell death and aging in human hair cells by altering microRNA levels.

Red light at 8 mW/cm2 most effectively promotes hair cell growth and affects key growth pathways, especially in cells treated with a hair loss-related hormone.

Gender affects wool traits in sheep, with males and females showing differences in skin proteins related to wool growth.

Radiation treatment causes skin fibrosis by increasing certain fibroblast subpopulations, but using a c-Jun inhibitor or fat grafting can reduce this effect.

The exact identity of skin stem cells and how skin cells differentiate is not fully known.

Fgf20 is important for the development and regulation of the cells that form the base of hair follicles.

People need different amounts of biotin based on age and it's important for health, with many foods providing enough.

People need different amounts of biotin based on age, and not getting enough can cause health problems.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

P-cadherin is important for hair growth and health, and its problems can cause hair and skin disorders.

Self-amplifying RNA could be a better option for protein replacement therapy with lower doses and lasting effects, but delivering it into cells is still challenging.

PRP can help regrow hair in people with alopecia.

The local environment is crucial for cell development in the tongue.

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

Plant extracts can help prevent hair loss and promote hair growth.

Alopecia areata and vitiligo share immune system dysfunction but differ in specific immune responses and affected areas.

Wound-induced hair follicle creation is a complex process in adult mammals that involves various cells and immune responses, and understanding it better could help improve skin healing strategies.

New molecules involved in skin and hair growth were identified, improving understanding and future treatments.

Rat hair follicle stem cells have functional oxytocin receptors, useful for studying neuropsychiatric disorders.
