Standardizing stroke animal models improves pre-clinical research. This guide offers best practices for selecting models and designing experiments, aiming to enhance the translation of neuroprotection findings to clinical practice.

Area of Science:

Neuroscience
Translational Medicine
Animal Models

Background:

Effective stroke therapies remain a challenge for researchers and clinicians.
Pre-clinical experimental models for neuro-protective agents often present limitations impacting clinical trial success.

Purpose of the Study:

To standardize methods for developing stroke animal models across Spain.
To create a best-practice guide for improving experimental stroke research.

Main Methods:

Development of a guide by experienced stroke research groups.
Recommendations cover animal model selection (species, strain, age, sex, risk factors) and experimental design.
Emphasis on sham controls, sample size calculation, randomization, blinding, outcome assessment, and monitoring (temperature, blood flow).
