iChip

iChip

The cultivation of environmental microorganisms has long been hindered by the inability to replicate complex native conditions in vitro. The isolation chip (iChip) addresses this limitation by facilitating the growth of previously uncultivable microorganisms through in situ incubation. Designed for high-throughput microbial cultivation, the iChip comprises hundreds of microchambers, each capable of housing a single microbial cell. These microchambers are loaded with a mixture of molten agar and...

Background:

Developing functional liver constructs for research and drug development is crucial.
Existing methods for hepatic cell patterning have limitations in construct strength and long-term functionality.
Need for robust, transferable liver models that mimic in vivo architecture.

Purpose of the Study:

To develop a novel dielectrophoresis (DEP)-based system for creating transferable hepatic cell constructs.
To generate liver-lobule mimetic patterns for enhanced cell function and viability.
To enable long-term functional studies and drug development applications using these constructs.

Main Methods:

Utilized coplanar dielectrophoresis (DEP) for cell patterning.
Employed paper-reinforced gel substrates for construct strength and transferability.
Assessed hepatic cell viability using fluorescent cell staining over 3 days.
Measured liver-specific functionality (albumin secretion) in patterned versus un-patterned cells.

Main Results:

Hepatic cells formed DEP field-induced structures mimicking liver lobule patterns.
Constructs demonstrated sufficient strength for transfer into 96-well plates.
Significant enhancement in albumin secretion was observed in layered, patterned HepG2/C3A cells compared to controls.
Maintained hepatic cell viability over a 3-day period.

Conclusions:

The novel DEP system successfully generates transferable, lobule-mimetic hepatic cell constructs.
Layer patterning significantly enhances liver-specific functionality and maintains cell viability.
This 'build and transfer' approach holds promise for organ-on-chip development and drug discovery.
