Apoptosis, not oxidative stress, is linked to aging in mice with mtDNA mutations.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Hair greying is caused by oxidative stress damaging hair follicles and melanocytes.

Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

Stress in mice delays hair growth and treatments blocking substance P can partly reverse this effect.

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

Researchers found 44 proteins that change during different hair growth stages and may be important for hair follicle function.

Taxol damages hair growth cells, causing hair loss.

Mice genetically modified to produce more Del1 protein had faster hair regrowth.

Two microRNAs affect hair follicle development in sheep by targeting specific genes.

Exosomes show promise for tissue repair and regeneration with advantages over traditional cell therapies.

Inflammation helps stem cells repair tissue by directing their behavior.

CXXC5 is a protein that controls cell growth and healing processes, and changes in its activity can lead to diseases like cancer and hair loss.

Enzymes are classified into six types and are essential for many biological processes, with only a few targeted by drugs.

Latanoprost therapy potentially caused a woman's white hair to darken again.

Toll-like receptors are important for wound healing, but can slow it down in diabetic wounds.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

Testosterone is crucial for development, growth, and various body functions in mammals.

Maintaining DNA integrity in stem cells is crucial to prevent aging and cancer.

The gene p53 is crucial for removing damaged cells to allow for healthy tissue renewal.

COVID-19 might worsen symptoms and progression of benign prostatic hyperplasia, possibly due to inflammation and metabolic disturbances in the prostate gland. More research is needed to confirm this.

Male hormones cause different growth in identical human hair follicles due to their unique epigenetic characteristics.

DHEA improved brain function and behavior in old monkeys and had additional health benefits.

The document concludes that hair loss is complex, affects many people, has limited treatments, and requires more research on its causes and psychological impact.

A woman's progressive hair loss was correctly diagnosed as a rare condition called fibrosing alopecia in a pattern distribution after initially being mistaken for a more common type.

TYK2 inhibition may help treat alopecia areata by promoting hair growth and reducing immune response.

Nitric Oxide has potential in medicine, especially for infections and heart treatments, but its short life and delivery challenges limit its use.

Androgens cause oil-producing skin cells with androgen receptors to mature and produce more oil.

Melatonin helps grow more secondary hair follicles in young goats, improving cashmere production.
