RODENT STROKE MODEL GUIDELINES FOR PRECLINICAL STROKE TRIALS (1ST EDITION)

Area of Science:

• Neuroscience
• Translational Medicine
• Animal Models

Background:

• Translational stroke research requires highly reproducible models for reliable preclinical trial data.
• Current stroke models exhibit significant infarct variation (5%-200%), hindering inter-laboratory comparability.
• Existing guidelines (STAIR, GLP) inadequately address factors causing outcome variability.

Purpose of the Study:

• To identify and address critical factors influencing outcome variation in experimental stroke models.
• To provide the first edition of stroke model guidelines to improve reproducibility and comparability.
• To foster discussion and achieve consensus among stroke researchers on standardized practices.

Main Methods:

• Literature review of factors affecting stroke model outcome variation.
• Analysis of critical elements including anesthesia, physiological environment, and outcome observation.
• Development of a preliminary set of guidelines for stroke model implementation.

Main Results:

• Identified key factors contributing to outcome variability in stroke models.
• Highlighted the inadequacy of current recommendations in addressing these factors.
• Proposed a set of guidelines to standardize stroke model research.

Conclusions:

• Standardized guidelines are essential for improving the quality and comparability of experimental stroke research.
• Addressing factors like anesthesia and physiological maintenance can reduce outcome variation.
• The proposed guidelines aim to initiate a community-wide discussion for future revisions and consensus.
