What is chip liver?

What is chip liver?

Liver-on-a-chip is a 3D in vitro hepatic microphysiological system aiming to recreate the conditions of liver tissue on a microscopic scale (15). An ideal liver-on-a-chip is a higher-throughput system capable of mimicking conditions of hepatocytes and the dynamic physicochemical hepatic environment (Figure 1).

What is organ on a chip technology?

An organ-on-a-chip (OOC) is a multi-channel 3-D microfluidic cell culture, integrated circuit (chip) that simulates the activities, mechanics and physiological response of an entire organ or an organ system, a type of artificial organ.

What is kidney on a chip?

Inside kidney-on-a-chip are thousands of live kidney cells that model the functions of a human kidney. By giving researchers the ability to test multiple drugs at the same time, kidney-on-a-chip may lead to a quicker and safer approval process for new medications.

Are organs on chips expensive?

CN Bio Innovations also works on a human body-on-a-chip. The company sells a liver-on-a-chip, with prices for the LiverChip starting at about $22,000. Using this technology is faster and far more cost-effective than animal research.

How does lung on a chip work?

The lung-on-a-chip is a complex, three-dimensional model of a living, breathing human lung on a microchip. The device is made using human lung and blood vessel cells and it can predict absorption of airborne nanoparticles and mimic the inflammatory response triggered by microbial pathogens.

What is brain on a chip?

Many of these platforms are called “Brains-on-a-Chip”—a term that was originally used to refer to microfluidics-based systems containing miniature engineered tissues, but that has since expanded to describe a vast range of in vitro central nervous system (CNS) modeling approaches.

What is a liver biochip?

These chips contain two cell culture compartments connected in series, one of which was designed to house liver tissue. Cells are seeded onto the polystyrene biochip either in monoculture or co-culture, using human hepatocytes and NPCs.

What is the emulate liver-chip?

The quad-culture Emulate Liver-Chip combines four human cell types in a dynamic microenvironment to support in vivo like gene expression, functionality, and physiology. Applications include general and mechanistic toxicity evaluation, as well as biomarker identification and mechanism of action determination.

What cells are in the liver-chip?

The Liver-Chip includes primary hepatocytes, stellate cells, Kupffer cells, and liver sinosoidal endothelial cells to capture complex cell-cell interactions.

How do you extract NPCs from liver cells?

When harvested alone, the NPCs of the liver can be enriched, at the expense of hepatocyte recovery, by using a pronase-collagenase perfusion method [79], [80]. For isolating both cell components, collagenase perfusion followed by density centrifugation are used to collect and separate the hepatocytes from the NPCs, respectively.
