简介：
Overview
This article describes a method for establishing a triple cell culture model of the blood-brain barrier using primary human brain microvascular endothelial cells, astrocytes, and pericytes. The model is designed for studying neurovascular unit dysfunction during ischemic stroke and for screening drug candidates.

What is the significance of the blood-brain barrier?
The blood-brain barrier protects the brain from harmful substances while allowing essential nutrients to pass through.
How does this model improve upon previous models?
This model incorporates multiple cell types to better mimic the human blood-brain barrier's complexity and functionality.
What are the implications for drug discovery?
The model allows for screening of drug candidates that can target the blood-brain barrier effectively during ischemic stroke.
What conditions are maintained during cell culture?
Cells are cultured in a 5% carbon dioxide incubator at 37 degrees Celsius to ensure optimal growth conditions.
Can this model be used for other neurological conditions?
While primarily designed for ischemic stroke, it may also be applicable to other conditions affecting the blood-brain barrier.
What are the next steps for this research?
Future studies will focus on testing various drug candidates and further refining the model for enhanced accuracy.
