The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

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

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

Hair follicles could be used to noninvasively monitor our body's internal clock and help identify risks for related diseases.

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.

Fat cells are important for healthy skin, hair growth, and healing, and changes in these cells can affect skin conditions and aging.

Understanding hair biology is key to developing better treatments for hair and scalp issues.

Hair growth and development are controlled by specific signaling pathways.

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.

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.

Mouse zigzag hair bends form due to a 3-day cycle of changes in hair progenitors and their environment.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

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

BMAL1 and Period1 genes can influence human hair growth.

The circadian clock plays a key role in hair growth and its disruption can affect hair regeneration.

Understanding and tracking our body's natural daily rhythms could help improve heart health.

Disrupted sleep patterns can harm skin and hair cell renewal, but melatonin might help.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Researchers developed a way to study human body clocks using hair tissue, which works similarly in both healthy and dementia patients.

Different light affects cell functions and can help treat skin conditions.

The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.

MicroRNAs are important for skin health and could be targets for new skin disorder treatments.

Bright light during the day doesn't change most human clock genes but may slightly increase Rev-erb-ß.

Topical L-thyroxine may help with wound healing and hair growth but should be used short-term due to potential risks.

Enzymes involved in Vitamin A metabolism affect hair growth and type in mice.

Excess androgens may cause PCOS, not just be a symptom.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.

Hair follicles on the scalp interact with and respond to the nervous system, influencing their own behavior and growth.
