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.

PTEN helps control the number and health of skin stem cells by working with the protein BMAL1.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

Non-immune dermal cells dominate, epidermal cells increase after day 9, and certain immune cells persist beyond inflammation in wound-induced hair follicle regeneration.

Activating a protein called β-catenin in adult skin can make it behave like young skin, potentially helping with skin aging and hair loss.

Stress in hair follicle stem cells causes inflammation in a chronic skin condition through a specific immune response pathway.

Fat tissue stem cells show promise for repairing different body tissues and are being tested in clinical trials.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Lack of Crif1 in hair follicle stem cells slows down hair growth in mice.

Dying cells can help with faster healing and new hair growth by releasing a growth-promoting molecule.

Hes1 protein is important for hair growth and regeneration, and could be a potential treatment for hair loss.

Ovol2 is crucial for hair growth and skin healing by controlling cell movement and growth.

The new method can create hair follicle-like structures but not complete hair with roots and shafts, needing more improvement.

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

The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.

Cat color patterns are determined early in development by gene expression and epidermal changes, with the Dickkopf 4 gene playing a crucial role.

3D bioprinting with special hydrogels can create artificial skin that heals wounds and regrows hair in mice.

Understanding where cancer cells come from helps create better prevention and treatment methods.

Activating Nrf2 in skin cells speeds up wound healing by increasing the growth of certain stem cells.

The research found proteins in human skin cells that help with wound healing and hair growth, which could lead to new treatments.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

γδ T cells help with hair growth during wound healing in mice.

A special bioink with nanoparticles helps regrow hair by reducing inflammation and promoting hair growth signals.

Women with PCOS are at high risk of glucose metabolism issues and heart diseases, especially if overweight, highlighting the need for early intervention.

ILC1-like cells may contribute to hair loss in alopecia areata.

IL-17 and certain immune cells are linked to more severe alopecia areata.

Free Testosterone Index, bioavailable testosterone, and androstenedione are the most accurate for diagnosing excess male hormones in PCOS.

Androgens increase growth factors in skin cells, which may lead to acne.
