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 plant hormone auxin activates the TOR pathway, affecting gene expression related to growth and cell size.

The study showed that brown planaria can be used to cheaply test if local plants can stop cell growth.

Butyrate helps hair grow longer, improves hair cell health, increases pigment production, and boosts hair's natural defenses.

Skin changes throughout life, from development before birth to aging effects like wrinkles, influenced by both genetics and environment.

The document concludes that Cutaneous Lupus Erythematosus has different forms, is influenced by genetic and environmental factors, and can be treated with various medications, but more targeted therapies are needed.

Finasteride diffuses spontaneously through SDS micelles, suggesting they can replace living cell membranes.

Men are more likely to get infectious skin diseases, while women are more prone to autoimmune and pigment-related skin conditions, influenced by biological and environmental factors.

Merkel cells may have roles in sensing magnetic fields, creating fingerprints, Reiki energy healing, passing on environmental information to offspring, and influencing hair shape.

Hair gets thinner, grayer, and changes texture with age due to genetics, environment, and cellular changes, affecting the growth cycle.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

Glycerol may improve wound healing and prevent keloids, a device can measure itch intensity, male pattern baldness is highly heritable, and fumaric acid esters may work for psoriasis by causing cell death in T cells.

Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.

Transplanting growing hair follicles into scars can help regenerate and improve scar tissue.

Polyurethane dressings show promise for wound healing but need improvements to adapt better to the healing process.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Jasmonic acid helps plants grow, defend against threats, and survive stressful conditions like drought and salt.

New culture method keeps human skin stem cells more stem-like.

Vitamin A may influence hair loss conditions like alopecia, but more research is needed to understand how.

Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.

The document concludes that using stem cells to regenerate hair follicles could be a promising treatment for hair loss, but there are still challenges to overcome before it can be used clinically.

Frontal Fibrosing Alopecia's cause is unclear, affects mainly postmenopausal women, and current treatments focus on stopping hair loss rather than regrowth.

Changing the structure of the hair follicle's environment can affect hair quality but doesn't stop hair growth.

The scalp has more diverse bacteria, while hair has more bacteria and unique types.

Feather patterns form through genetic and epigenetic controls, with cells self-organizing into periodic patterns.

Pollution increases a compound in the skin that can lead to faster aging and more inflammation.

Aryl hydrocarbon receptor overexpression found in miniaturized hair follicles in female hair loss.

Adult mesenchymal stem cells can help regenerate tissues and are promising for healing bones, wounds, and hair follicles.

ADSCs help in wound healing and skin regeneration but need more research for full understanding.
