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.

Dynamic, light touch is sensed through a common mechanism involving Piezo2 channels in sensory axons.

4-aminopyridine, a FDA-approved drug, speeds up skin wound healing and tissue regeneration.

Sensory neuron and Merkel-cell changes in the skin happen independently during normal skin maintenance.

Sensory neuron and Merkel cell changes in the skin happen independently during normal skin maintenance.

Merkel cells stabilize nerve endings in the skin, and they change independently of each other.

Different types of hairs on a rat's hindlimb have varying levels and patterns of nerve innervation.

Sensory neuron changes and Merkel-cell changes in the skin happen independently during normal skin maintenance.

Sensory neuron remodeling and Merkel-cell changes in the skin happen independently.

Sensory neuron and Merkel cell changes in the skin happen independently during normal skin maintenance.

Sensory neurons and Merkel cells remodel at different rates during normal skin maintenance.

Manatee whiskers are specially adapted for touch in water.

Human Schwann cells can be quickly made from hair follicle stem cells for nerve repair.

P2X₃-IR fibers are widespread in rat skin and likely help detect pain.

HAP stem cells can repair nerves and spinal cords by becoming Schwann cells.

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.

TRPA1 is crucial for mechanical sensitivity in skin sensory neurons.

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

Skin has specialized touch receptors that can tell different sensations apart.

Late pregnancy helps repair brain damage in rats due to the GABAergic system.

Exosomes help nerve fibers grow by affecting specific cell signaling pathways.

The skin and mucous membranes can regenerate over the basement membrane after damage, using nearby surviving cells.

The document concludes that understanding how hair follicles naturally die and regenerate is important for insights into organ development and could impact health and disease treatment.

Scientists successfully grew mini hair follicles using human skin cells, which could help treat baldness.

The document explains how male reproductive hormones work and affect the body.

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

Human skin can make serotonin and melatonin, which help protect and maintain it.

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

The secretome from mesenchymal stem cells is a promising treatment that may repair tissue and avoid side effects of stem cell transplantation.
