Minoxidil treatment increases aorta elasticity and reduces stiffness in aged mice, potentially helping with age-related heart issues.

Eating selenium-rich rice improved antioxidant activity and signs of aging in mice.

Older mice healed wounds better but lost more weight and might have weaker immune systems afterward.

Aged individuals heal wounds less effectively due to specific immune cell issues.

Probiotic bacteria improved skin and hair health in aged mice.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

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.

Young C57BL/6 mice heal better than BALB/c mice, and older mice heal faster but regenerate worse.

A certain signaling pathway in mice, when increased, causes hair to gray by depleting the cells that give hair its color.

Deleting the PTEN gene in mice causes nerve cells to grow larger and heal better after injury, but may cause overgrowth and hair loss in older mice.

Activating TLR5 in the gut can extend lifespan and improve health in aged mice.

Minoxidil helps protect and rebuild elastic fibers in arteries, improving artery function, especially in older females.

Gene therapy in mice increased lifespan and improved health without causing cancer.

Pro-IGF-II improves muscle repair in old mice.

Wounds can regenerate hair in young mice, but this ability declines with age, offering insights for improving tissue regeneration in the elderly.

A molecule called α-ketobutyrate was found to extend lifespan and improve aging-related symptoms in worms and mice by activating certain cellular pathways and may help develop anti-aging treatments for humans.

Spermidine helps protect against aging by preserving telomere length.

Argireline significantly reduces wrinkles.

Aging-related changes in hair follicle stem cells can be partially reversed with a specific treatment.

Certain small molecules can promote hair growth by activating a cellular cleanup process called autophagy.

Older skin has higher cancer risk due to inflammation and stem cell issues.

Fat tissue under the skin affects hair growth and aging; reducing its inflammation may help treat hair loss.

A new method using special materials can help regrow hair by creating small wounds.

Mitochondrial dysfunction contributes to skin aging and hair loss.

Miz1 is essential for proper hair structure and growth.

Applying certain inhibitors to the skin can promote hair growth without harming cells.

Older hair follicle stem cells have a reduced ability to renew themselves, leading to more hair loss.

Wnt signaling may be linked to heart diseases in aging and could be a target for future treatments.

Collagen and TGF-β2 help maintain hair cell shape and youthfulness.

Runx genes are important for stem cell regulation and their roles in aging and disease need more research.
