The protein Gnαs is found more in black mice than white mice and may influence their coat color.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

New techniques have enhanced our understanding of how stem cells function and the role of mutations in aging tissues, which may influence future cancer therapies.

Male and female bodies respond differently to stress, influenced by hormones and development stages, with implications for stress-related diseases.

Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Hair can naturally regain color, and stress might influence greying and its reversal.

Testosterone may slow down wound healing and increase inflammation.

New targets for making and using brain-synthesized steroids could lead to better treatments for brain disorders and alcoholism.

The protein folliculin, involved in a rare disease, works with another protein to control how cells stick together and their organization, and changes in this interaction can lead to disease symptoms.

Insulin resistance may contribute to various skin diseases and treating it could improve skin health and prevent more serious conditions.

A 17-year-old female with adrenogenital syndrome produces very high levels of androgens, which prevent complete feminization despite high estrogen doses.

The document concludes that hair biology is complex and there are still unanswered questions about hair loss and follicle changes.

Androgens reduce BMP2, which weakens the ability of certain cells to help hair stem cells become different types of cells.

Higher free testosterone levels in men are linked to a stronger immune response, not weaker.

Histone demethylases can change gene expression and may be linked to diseases like cancer.

Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Aromatase gene variation may increase female hair loss risk.

Longer CAG repeat lengths in the androgen receptor gene are linked to higher testosterone levels in women with PCOS.

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.

Growing hair cells with dermal cells can potentially treat hair loss.

Ptprq has multiple forms that change during inner ear development.

Dyclonine can effectively reduce skin issues by inhibiting the TRPV3 channel.

Hdac1 and Hdac2 help maintain and protect the cells that control hair growth.

Pangolins have lost some skin-related genes, but kept others, leading to their unique scales and skin features.

Pangolins have lost some skin-related genes, but kept others, showing complex skin evolution.

Androgens and androgen receptors are important for metabolic health, affecting how the body uses glucose and fats through mitochondrial function.

Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.

Human enzymes can detoxify harmful substances but might also increase their cancer risk.
