Background:

In vitro modeling of human brain connectomes is crucial for understanding the central nervous system's structure-function relationship.
Current models lack the ability to replicate the cellular heterogeneity of brain regions, hindering research into neurodegenerative diseases.
Developing physiologically relevant neural structures is essential for advancing drug screening for neurological disorders.

Purpose of the Study:

To present an innovative microfluidic design to overcome limitations in current in vitro brain models.
To enable the recapitulation of cellular density and number heterogeneity found in different brain regions.
To offer enhanced neuro-engineered microfluidic platforms for neuroscience research and organ-on-a-chip applications.

Main Methods:

Development of a microfluidic device for controlled and uniform cellular population deposition.
Utilizing variable-sized and shaped plating chambers for tailored cell seeding.
Fine-tuning hydrodynamic resistance and cell deposition rates to control neuron seeding from thousands to millions.

Main Results:

The microfluidic design successfully allows for controlled seeding of diverse cellular populations.
Neuron numbers in plating chambers can be precisely adjusted, ranging from 1,000 to 1,000,000.
The device enables the creation of neurofluidic platforms with enhanced structural architectures.

Conclusions:

The innovative microfluidic device significantly enhances in vitro brain models by addressing cellular heterogeneity.
This technology provides a novel platform for studying human neurodegenerative diseases, including Alzheimer's and Parkinson's.
The developed neuro-engineered platforms serve as advanced organ-on-a-chip models for neuroscience research.
