Nerves are crucial for the regeneration of various body parts in many animals.

Mice that can regenerate tissue have cells that pause in the cell cycle, which is important for healing, similar to axolotls.

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.

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 teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

New antiscarring strategies show promise, including drugs, stem cells, and improved surgical techniques.

Fibroblast Growth Factors (FGFs) are important for tissue repair and regeneration, influencing cell behavior and other factors involved in healing, and are crucial in processes like wound healing, bone repair, and hair growth.

Using three different drugs together may better treat eye diseases like glaucoma and macular degeneration.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

A special receptor in sensory nerve endings helps control how they respond to stretching.

The study found that nerve signals are stronger when there are more connection points, but not necessarily denser, along the nerve's path in the spine.

Mouse touch-sensitive nerve cells adjust their connections based on competition with other similar cells.

Procyanidins from grape seeds reduce nerve pain by blocking specific proteins and inflammation.

Researchers found a new ABCD1 gene mutation linked to a rare brain and nerve disorder with unusual brain changes.

Surgery to fix a broken upper arm bone can sometimes lead to nerve damage.

Scientists found a specific group of itch-sensing nerve cells in mice important for feeling itch but not for sensing heat or touch.

Opioid painkillers can cause many side effects, including breathing problems and addiction, but are generally considered safe when used properly.

Patients who survive critical illness often face long-lasting physical, mental, and cognitive issues, with many unable to return to work within a year.

Touch sensitivity in mouse skin decreases during hair growth due to changes in touch receptors.

Boosting mitochondrial energy production with supplements like acetyl-L-carnitine may improve aging-related cellular function and health conditions.

The nervous system helps control stem cell behavior and immune responses, affecting tissue repair and maintenance.

Lanceolate complexes in mouse hair follicles are essential for touch and depend on specific cells for maintenance and regeneration.

Injection lipolysis effectively reduces small fat deposits and should be done with care and proper patient selection.

Long-term use of a certain medication can worsen erectile function in aged rats by damaging penile muscle cells.

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

Women with myotonic dystrophy might get diseases related to male hormones because their body tissues are extra sensitive to these hormones.

Stress may affect hair growth by influencing hair follicle development and could contribute to hair loss.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Voriconazole can cause serious side effects, especially in long-term use.
