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

Low ERCC3 gene activity is linked to non-pigmented hair growth.

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

The gene p53 is crucial for removing damaged cells to allow for healthy tissue renewal.

Nicotinic acid reduces excessive oil production in skin cells by activating a specific receptor, which could help treat acne.

Valproic acid can cause hair loss when taken orally but may promote hair growth when applied topically.

BMI1 is essential for preventing hair greying and maintaining hair color.

Researchers found three types of melanocytes in developing mouse skin, each with different genes and locations.

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

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.

Human hair follicle dermal cells can effectively replace other cells in engineered skin.

Higher minoxidil dose helps hair growth in non-responders without side effects.

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

Hair follicle regeneration needs special conditions and young cells.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

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

The research found a way to identify and study skin cells with stem cell traits, revealing they behave differently in culture and questioning current stemness assessment methods.

The role of γδT-cells in causing alopecia areata remains unclear.

The circadian clock influences the behavior and regeneration of stem cells in the body.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

Acne patients' skin, both with and without lesions, shows a strong immune response and higher antimicrobial activity.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

There are still challenges in diagnosing and treating chronic skin diseases, but there is hope for future improvements.

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

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

Researchers improved a method to study individual cells in newborn mouse skin and found a way to assess the severity of a skin condition in humans.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

New drugs for heart disease may be developed from molecules secreted by stem cells.
