Damaging mitochondrial DNA in mice speeds up aging due to increased reactive oxygen species, not through the p53/p21 pathway.

Senescent melanocytes can boost hair growth by activating hair stem cells.

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

Researchers developed a mouse model that tracks hair growth using bioluminescence, improving accuracy in studying hair cycles.

Hair transplant surgery can rebuild muscle and nerve connections, allowing transplanted hairs to stand up like normal hairs.

Mice with a Gsdma3 gene mutation have thicker skin and longer hair follicle openings due to increased β-catenin levels.

The E2 protein affects gene activity in hair follicles of mice.

Increasing the levels of a protein called FGF9 can promote hair growth, but humans may not respond the same way due to a lack of certain cells.

Skin may help in getting rid of excess iron through the process of skin cell renewal.

The study found that tight junctions reach the top layer of the skin's stratum granulosum, not just the second top layer as previously thought.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

Runx1 controls fat-related genes important for normal and cancer cell growth, affecting skin and hair cell behavior.

Telomere damage affects skin and hair follicle stem cells by messing up important growth signals.

Mice without certain skin proteins had abnormal skin and hair development.

Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.

Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.

Hair follicle stem cells are a promising source for tissue repair and treating skin or hair diseases.

Eph/ephrin signaling is important for skin cell behavior and could be targeted to treat skin diseases.

Calcium is important for stem cell function and maintenance, especially in blood and skin cells.

ILK and ELMO2 help cells move and stick together, important for wound healing and hair growth.

Stem cell therapies show promise for treating various diseases but face challenges in clinical use and require better monitoring techniques.

Gap junctions help control feather pattern formation in chickens.

The plant extract remedy Satura® Rosta promotes hair growth and regrowth without negative effects.

THBS4 helps hair grow by activating hair follicle stem cells.

Targeting the HEDGEHOG-GLI1 pathway could help treat keloids.

The vitamin D receptor is essential for skin stem cells to grow, move, and become different cell types needed for skin healing.

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