The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Certain genes related to sulfur metabolism are more active during the growth phase of Cashmere goat wool, and melatonin might help this process.

Sostdc1 controls the size and number of hair and mammary gland structures.

Platelet-derived products help regenerate tissue and are used in various skin and hair treatments.

Cannabinoids may help treat various skin conditions.

NIPP1 is important for healthy skin and could help treat skin inflammation.

The conclusion is that accurately replicating the complexity of the extracellular matrix in the lab is crucial for creating realistic human tissue models.

Keratin protein production in cells is controlled by a complex system that changes with cell type, health, and conditions like injury or cancer.

TGFβ signaling prevents sebaceous gland cells from producing fats.

Phospholipase A2 enzymes play key roles in skin health and disease.

A mouse gene mutation increases the risk of skin cancer.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

Vitamin D receptor is crucial for skin wound healing.

A mutation in the Soat1 gene causes hair structure defects and other health issues in AKR/J mice.

Using polyethylenimine-DNA to deliver the hTERT gene can stimulate hair growth and may be useful in treating hair loss, but there could be potential cancer risks.

Cats with abnormal hair had DSG4 gene changes causing hair problems.

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

Keratin injections can promote hair growth by affecting hair-forming cells and tissue development.

t-Flavanone helps improve male pattern hair loss by making hair roots stronger.

Testosterone can both promote hair growth and cause baldness by affecting hair growth signals.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

Ginsenoside F2 from ginseng may increase hair growth better than standard treatments by affecting cell growth signals.

Rabbits lacking the Hoxc13 gene show similar hair and skin issues to humans with ECTD-9, making them good for research on this condition.

A hair-growth formula with cystine and thiamin helps protect skin cells against UV damage and improves their growth.

The document explains how to create detailed biological pathways using genomic data and tools, with examples of hair and breast development.

The document concludes that hair is complex, with a detailed growth cycle, structure, and clinical importance, affecting various scientific and medical fields.

Cyclosporine A may help treat hair loss by blocking a protein that inhibits hair growth.

Different methods of preparing Platelet-Rich Plasma (PRP) can affect wound healing and hair regrowth in plastic surgery. Using a kit with specific standards helps isolate PRP that meets quality criteria. Non-Activated PRP and Activated PRP have varying effects depending on the tissue and condition treated. For hair regrowth, Non-Activated PRP increased hair density more than Activated PRP. Both treatments improved various aspects of scalp health.

Using micro-needling, low-level laser therapy, and platelet-rich plasma together significantly improves hair growth in people with hair loss.
