简介：
Overview
This study presents a detailed protocol for establishing a highly reproducible animal model of hemorrhagic transformation (HT) using middle cerebral artery occlusion/reperfusion (MCAO/R) in C57BL/6 mice with acute hyperglycemia. The protocol demonstrates good repeatability, high stability, and low animal mortality, making it suitable for preclinical research.
Key Study Components

What is hemorrhagic transformation?
Hemorrhagic transformation refers to the bleeding that occurs in the brain tissue following a stroke, which can complicate recovery.
Why use C57BL/6 mice for this study?
C57BL/6 mice are widely used in research due to their well-characterized genetics and consistent responses in experimental settings.
What are the implications of acute hyperglycemia in stroke research?
Acute hyperglycemia can exacerbate brain injury and influence the outcomes of stroke models, making it an important factor to consider.
How does MCAO/R work?
MCAO/R involves temporarily occluding the middle cerebral artery to simulate a stroke, followed by reperfusion to study recovery processes.
What are the benefits of this protocol?
The protocol offers high reproducibility, stability, and low mortality, making it suitable for extensive preclinical research.
Can this model be used for other types of research?
While primarily focused on hemorrhagic transformation, the model may be adapted for other studies related to stroke and brain injury.
