Background:

The brain's complexity necessitates advanced in vitro models for research.
The blood-brain barrier (BBB) is a critical component of the central nervous system, regulating substance transport.
Current in vitro BBB models struggle to replicate in vivo characteristics.

Purpose of the Study:

To review and analyze existing in vitro blood-brain barrier models.
To identify parameters affecting the accuracy of current BBB models.
To propose novel approaches for developing more sophisticated BBB models.

Main Methods:

Comprehensive literature review of microfabrication and microfluidic techniques for BBB models.
Analysis of key parameters influencing the fidelity of in vitro BBB models.
Exploration of synergistic integration of BBB models with neuronal tissue biofabrication.

Main Results:

Existing in vitro BBB models have limitations in mimicking in vivo conditions.
Several parameters critically impact the accuracy and predictive power of current models.
Synergistic approaches show promise for enhanced model development.

Conclusions:

Developing accurate in vitro BBB models remains a significant challenge.
Future models should integrate neurovascular unit principles and advanced biofabrication.
Vascularized brain organoid and microfluidic models represent promising next-generation BBB research tools.
