Complete Spinal Cord Injury and Brain Dissection Protocol for Subsequent Wholemount In Situ Hybridization in Larval Sea Lamprey

Simple Explanation

This paper details a protocol for performing complete spinal cord injuries on larval sea lampreys to study nerve regeneration. The protocol includes instructions on how to house the lampreys, perform the spinal cord transection, and dissect the brain for in situ hybridization. This protocol allows researchers to investigate differences in gene expression between spinal cord neurons that regenerate well versus those that do not after injury.

Study Duration
Not specified
Participants
Larval sea lampreys (Petromyzon marinus L.), 10 – 14 cm in length (4 – 7 years old)
Evidence Level
Not specified

Key Findings

  • 1
    The protocol demonstrates a reliable method for complete spinal cord transection in larval sea lampreys.
  • 2
    The method allows for subsequent brain dissection and preparation for wholemount in situ hybridization to study gene expression.
  • 3
    The results show that the neogenin receptor is preferentially expressed in bad regenerators after spinal cord transection.

Research Summary

The study presents a detailed protocol for performing complete spinal cord transections in larval sea lampreys and subsequent brain dissection for wholemount in situ hybridization. The protocol includes methods for animal housing, surgical procedures, and tissue preparation, enabling the study of gene expression differences in regenerating neurons. The representative results demonstrate the utility of the protocol by showing differential expression of the neogenin receptor in good versus bad regenerating neurons after spinal cord injury.

Practical Implications

Understanding Regeneration Mechanisms

This protocol can help researchers understand the molecular mechanisms that govern nerve regeneration after spinal cord injury.

Identifying Therapeutic Targets

Identifying genes differentially expressed in good versus bad regenerators can reveal potential therapeutic targets for promoting regeneration.

Developing New Treatments

The lamprey model provides a platform for testing new treatments aimed at enhancing spinal cord regeneration.
