Protocol for inducing focal striatal stroke in mice using photothrombosis

Area of Science:

• Neuroscience
• Translational Medicine
• Animal Models

Background:

• Stroke is a leading cause of disability, necessitating reliable animal models for research.
• The striatum is a critical brain region affected by stroke, leading to motor impairments.
• Current models may lack standardization, hindering reproducibility in preclinical studies.

Purpose of the Study:

• To present a standardized protocol for inducing focal striatal stroke in mice.
• To enable consistent modeling for mechanistic stroke research.
• To facilitate preclinical testing of novel therapeutic interventions.

Main Methods:

• Photothrombotic induction of focal striatal stroke in mice.
• Magnetic resonance imaging (MRI) for stroke assessment.
• Open field behavioral tests for motor deficit evaluation.
• Tissue collection and immunofluorescence for post-stroke analysis.

Main Results:

• The protocol ensures consistent and reproducible focal striatal stroke induction.
• The method allows for detailed monitoring of stroke progression and associated motor deficits.
• Standardized procedures facilitate reliable data acquisition for research.

Conclusions:

• This protocol offers a robust and reproducible method for modeling striatal stroke in mice.
• The standardized approach supports mechanistic investigations and preclinical therapeutic development.
• This model is valuable for advancing stroke research and potential treatments.
