Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

A new method using fat tissue cells may help treat hair loss.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Exosomes could be effective for improving skin health and treating skin diseases.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

Blocking β-catenin in skin cells improves hair growth during wound healing.

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

Melanocytes are diverse cells important for pigmentation and skin health, influenced by genetics and environment.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Telocytes might help with skin repair and regeneration.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

Hair and skin healing involve complex cell interactions controlled by specific molecules and pathways, and hair follicle cells can help repair skin wounds.

The document concludes that understanding adult stem cells and their environments can help improve skin regeneration in the future.

Hair follicle regeneration possible, more research needed.

Both main and alternative Wnt signaling are important for regrowing rodent whisker follicles.

Transplanted rat hair follicles grew hair and had increased but not fully restored nerve connections in mice.

Endo-HSE helps grow hair-like structures from human skin cells in the lab.

The review concludes that innovations in regenerative medicine, tissue engineering, and developmental biology are essential for effective tissue repair and organ transplants.

The fascial layer is a promising new target for wound healing treatments using biomaterials.

Keratin hydrogels from human hair show promise for tissue engineering and regenerative medicine.

CDP is crucial for lung and hair follicle cell development.

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

Male yak hair growth is influenced by DHT synthesis, which is promoted by 5α-red1 and AR during growth phases, while E2 may inhibit growth through ERα.

Human stem cells can help form hair follicles in mice.

Gene regulation could revolutionize hair color by altering pigmentation from within.

The conclusion is that recognizing hair growth cycles can improve the precision of dietary and health assessments from hair analysis.

Hair follicles may soon be used more for targeted and systemic drug delivery.

Accurate clinical, histological, and genetic methods are key for understanding and treating hair disorders.

EGF and FGF boost hair cell growth, hydrocortisone slows it, and minoxidil doesn't affect it.
