Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Collagen XVII is important for skin aging and wound healing.

Exosomes from fat-derived stem cells may help regrow hair.

The Bcl-2 protein is important for keeping hair follicle stem cells working and preventing hair loss.

Stem cells and their secretions could potentially treat stress-induced hair loss, but more human trials are needed.

Changing how mesenchymal stromal cells are grown can improve their healing abilities.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Platelet Rich Plasma (PRP) shows promise for tissue repair and immune response, but more research is needed to fully understand it and optimize its use.

Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.

N-acetyl-L-cysteine (NAC) can prevent DNA damage and protect cells from harm.

Scientists created a new cell line from Cashmere goat hair and found that cytokeratin 13 is a unique marker for certain skin cells.

Cellular senescence has both cancer-blocking and cancer-promoting effects, and targeting senescent cells may improve health and lifespan.

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.

Overactive Wnt signaling in mouse skin stem cells causes acne-like cysts and shrinking oil glands, which some treatments can partially fix.

Different body parts have varying levels of certain hair follicle markers.

New treatments for hair loss could involve using stem cells and a process called the Wnt/beta-catenin pathway to stimulate hair growth.

New treatment using engineered nanovesicles in hydrogel improves hair growth by repairing hair follicle cells in a mouse model of hair loss.

Facial plastic surgery has evolved to focus on less invasive techniques and innovative technologies for cosmetic and reconstructive procedures.

Cell therapy shows promise for treating severe psoriasis but needs more research to confirm safety and effectiveness.

A substance from a specific gel helped to grow hair effectively in mice, suggesting it could potentially be used to treat hair loss in humans.

Stem cell therapies show promise for hair regrowth but need more research to confirm effectiveness.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

LGR5 helps maintain corneal cell characteristics and prevents unwanted changes by controlling specific cell signaling pathways.

Scientists have made progress in creating replacement teeth, hair, and glands that work, which could lead to new treatments for missing teeth, baldness, and dryness conditions.

AcSDKP may help prevent skin and hair aging and promote their growth.

Some therapies using stem cells and platelet-rich plasma may help treat osteoarthritis, but more research is needed to ensure they are safe and effective.

Hyaluronic acid and polycaprolactone improve skin regeneration, with polycaprolactone having a stronger effect on healing and tissue repair.

New effective scar treatments are urgently needed due to the current options' limited success.

Hair aging is caused by stress, hormones, inflammation, and DNA damage affecting hair growth and color.

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.
