Understanding skin structure and development helps diagnose and treat skin disorders.

Signaling pathways are key targets for developing effective drugs.

Extracellular vesicles and androgen receptors may help identify prostate cancer resistance and reduce SARS-CoV-2 infection.

Different levels of shear stress affect where cells move and gather in a 3D-printed model, helping to better understand cell behavior in blood vessels.

Glycogen metabolism is important for energy and processes in human hair follicles, and hair follicles may produce glucose from lactate.

Steroid sex hormones activate matriptase in prostate cancer cells but not in breast cancer cells.

Certain proteins are essential for the growth of root hairs in barley.

UVB radiation changes the levels of certain microRNAs in skin cells, which may affect cell survival and hair growth.

Skin enzymes convert topical drugs into active forms, affecting drug effectiveness and safety.

Poplar seed hairs grow from the placenta at the ovary base, with endoreduplication playing a key role in their development, and share similar cellulose synthesis processes with cotton fibers.

Stem cells help heal wounds by rapidly dividing and migrating to the wound edge.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Calreticulin has roles in healing, immune response, and disease beyond its known functions in the endoplasmic reticulum.

The conclusion is that using drugs to block the TOR pathway might slow aging and prevent age-related diseases.

Msx and Dlx genes are crucial for development, controlling cell behaviors like growth and differentiation through their roles as gene regulators.

Mechanical stretching of the skin can promote hair growth by activating certain immune cells.

MIM is crucial for hair follicle formation and regeneration by controlling cilia formation and hedgehog signaling through its interaction with Cortactin and Src.

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

A new protein was made to detect specific skin cell growth receptors and worked in normal skin but not in skin cancer cells.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

Keratin 79 marks a new group of cells that are key for creating and repairing the hair follicle's structure.

Squalene-based carriers improve delivery of a treatment to hair follicles for alopecia areata.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.

Keratins are important for skin cell health and their problems can cause diseases.

Minoxidil needs activation to work, and minoxidil sulfate helps with hair growth and blood pressure.

Vitamins A, B3, C, D, and E can improve skin health and immunity.

A new mutation in the STING protein causes a range of symptoms and its severity may be affected by other genetic variations; treatment with a specific inhibitor showed improvement in one patient.

Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.
