简介：
Overview
This protocol describes the isolation of dorsal root ganglion (DRG) neurons from rats and their culture on a static pre-stretched cell culture system. This method enhances axon alignment and promotes myelination through subsequent co-culture with Schwann Cells (SCs).

What are dorsal root ganglion neurons?
Dorsal root ganglion neurons are sensory neurons located in the dorsal root of spinal nerves, responsible for transmitting sensory information.
Why is axon alignment important?
Axon alignment is crucial for effective nerve regeneration and proper signal transmission in the nervous system.
How does the pre-stretched culture system work?
The pre-stretched culture system applies mechanical tension to the cells, promoting alignment and growth in a desired direction.
What role do Schwann Cells play?
Schwann Cells support myelination of neurons, which is essential for rapid signal conduction in the nervous system.
What are the advantages of this protocol?
This protocol enhances both axon alignment and myelination, providing a valuable tool for nerve tissue engineering research.
