Summary
The peripheral nervous system (PNS) does more than just transmit signals; it plays crucial roles in tissue development and regeneration. Neural crest-derived cells within the PNS exhibit multipotency, contributing to diverse functions beyond typical nerve signaling.
Area of Science:
- Neuroscience
- Developmental Biology
- Regenerative Medicine
Background:
- The peripheral nervous system (PNS) is derived from neural crest stem cells and traditionally viewed for communication and autonomic control.
- Emerging evidence suggests the PNS has non-canonical functions in tissue homeostasis and regeneration.
Purpose of the Study:
- To review the newly identified, non-canonical functions of the peripheral nervous system.
- To describe the cellular and molecular mechanisms underlying these alternative roles.
Main Methods:
- Literature review of recent studies on PNS functions.
- Analysis of cellular and molecular data related to neural crest-derived cells in the PNS.
Main Results:
- The PNS harbors multipotent neural crest-like glial cells throughout the body.
- These cells can be reprogrammed in vivo to influence processes like pigmentation and regeneration.
- Non-canonical roles include significant contributions to tissue development and repair.
Conclusions:
- The PNS possesses critical, underappreciated functions in development and regeneration.
- Neural crest-derived cells within the PNS are key players in these alternative roles, offering new therapeutic avenues.

The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

8.1K
The nervous system is responsible for coordinating and regulating the body's functions. It functions through three main processes: sensory, integrative, and motor processes. Sensory function involves the detection and transmission of information about internal and external stimuli from sensory receptors to the CNS. The CNS processes this information through an integrative function, where it interprets and makes decisions based on the incoming sensory information. Finally, the motor function...

The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...

The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

17.3K
The nervous system, responsible for sensing, integrating, and responding to various stimuli, is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The PNS has two functional divisions: the sensory or afferent division and the motor or efferent division.
The sensory division transmits information from sensory receptors in the body to the CNS. It provides the CNS with knowledge about somatic senses (such as tactile, thermal, pain, and proprioceptive sensations)...
