Background:

Bottom-up tissue engineering aims to replicate native organ complexity by assembling functional modules.
Current strategies struggle to create controllable, perfusable microfluidic networks in 3D modular constructs.

Purpose of the Study:

To develop a bottom-up strategy for producing perfusable microchannels in 3D hydrogels via sequential assembly of microfluidic modules.
To investigate the impact of agarose-collagen composition on microchannel replication and 3D hydrogel assembly.
To evaluate the fluid transport properties of the engineered microfluidic networks.

Main Methods:

Sequential assembly of microfluidic hydrogel modules.
Investigation of agarose-collagen composition effects on hydrogel properties.
Incorporation of endothelial cells into the microfluidic network.
Dynamic culture within a custom-built bioreactor system.

Main Results:

Successfully produced interconnected, 3D predefined microfluidic networks in optimized agarose-collagen hydrogels.
Demonstrated full perfusability of the engineered microchannels.
Showcased the functionality of microchannels as fluid pathways, supporting endothelial cell spreading.

Conclusions:

The sequential assembly method effectively creates perfusable microfluidic networks in 3D hydrogels.
This technique holds potential for engineering 3D vascularized parenchymal constructs for regenerative medicine applications.
