What is the blood-brain barrier?
The blood-brain barrier is a selective permeability barrier that protects the brain from harmful substances while allowing essential nutrients to pass.
How does sepsis affect the brain?
Sepsis can lead to inflammation and disrupt the blood-brain barrier, potentially causing neurological complications.
What are microSIM devices?
MicroSIM devices are advanced tissue chip platforms designed for versatile in vitro modeling of biological systems.
Why is reproducibility important in tissue chip research?
Reproducibility ensures that results can be reliably replicated, which is crucial for validating scientific findings.
What role do astrocytes play in the blood-brain barrier?
Astrocytes support the blood-brain barrier by maintaining its integrity and regulating the exchange of substances between the blood and brain.
