Activating TERT in mice skin boosts hair growth by waking up hair follicle stem cells.

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

Looking older on the outside might be linked to aging faster on the inside and can be affected by lifestyle choices and health risks.

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

Low selenium levels can extend lifespan but worsen health issues.

Hair follicle studies suggest that maintaining telomere length could help treat hair loss and graying, but it's uncertain if mouse results apply to humans.

Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.

Lamins are vital for cell survival, organ development, and preventing premature aging.

Genetically-altered adult stem cells can help in wound healing and are becoming crucial in regenerative medicine and drug design.

Skin aging is caused by stem cell damage and can potentially be delayed with treatments like antioxidants and stem cell therapy.

Hair gets thinner, grayer, and changes texture with age due to genetics, environment, and cellular changes, affecting the growth cycle.

The document concludes that a deeper understanding of skin aging and photodamage is needed to create better skin treatments.

2011 dermatological research found new skin aging markers, hair loss causes, skin defense mechanisms, and potential for new treatments.

Short telomeres contribute to aging and cancer, and while telomerase can delay aging, it may also promote cancer.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Tranexamic acid reduces skin aging more in female mice.

Progeroid mouse models show signs of early aging similar to humans, helping us understand aging better.

A new ethical skin model using stem cells offers a reliable alternative for dermatological research.

Deleting the Trf1 protein in mice is safe and may help prevent cancer without major side effects.

Ayurvedic herbs may reduce side effects and improve effectiveness of cancer treatments.

The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.

Menopause reduces skin collagen and elasticity, and while estrogen therapy can help, its risks require careful consideration.

Premature graying of hair may suggest health issues and currently lacks effective treatments.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

Fisetin, a type of polyphenol, may help hair grow by increasing certain protein activities in cells.

Combining cosmetic procedures with lifestyle changes improves antiaging results.

Using polyethylenimine-DNA to deliver the hTERT gene can stimulate hair growth and may be useful in treating hair loss, but there could be potential cancer risks.

Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Fisetin in fruits and vegetables helps hair growth in mice.

Using a combination of specific cell cycle regulators is better for safely keeping hair root cells alive indefinitely compared to cancer-related methods.
