Why use liver-on-a-chip models?
The quest for more reproducible models to advance drug development and disease research is in full swing. Current animal models are known to have limitations when translating from preclinical to human trials, especially when considering effects on the liver.
A striking example is that almost half of the drugs found safe in established animal models were responsible for liver damage in clinical trials [1]. Thus, there are several approaches to improve translation between preclinical and clinical data, as illustrated in the table below [adapted from 1].
Every method has shortcomings, but liver-on-a-chip models offer the possibility to perform all the in vitro models, taking benefits from their advantages. As a new technology, there are no standards yet, and operating organ-on-a-chip systems requires specialized know-how. This is precisely what we are aiming to simplify with our platform.

How to culture a liver-on-a-chip model?
To simplify and standardize the organ-on-chip cultures, we have assembled a platform that automates most of the labour-intensive work. Although the schematics below might seem complicated, the principle is simple.
The OB1 pressure controller and the flow sensor control the media flow inside the chip according to your needs and parameters. The recirculation loop redirects the media between the reservoirs so your liver-on-chip model always receives enough nutrients while also being enriched with metabolites for later analysis. The level sensors are responsible for controlling which reservoir will empty first and ensuring that there is always media on top of your culture.
You can add your own proprietary chip to the system or commercial ones, as you prefer. This system is assembled as an automated platform that fits inside standard CO2 incubators and biosafety hoods.
The liver-on-a-chip pack includes:
- An OB1 flow controller (Elveflow)
- A Microfluidic flow sensor (MFS or BFS, Elveflow)
- Several Falcon reservoirs
- Recirculation loop
- Tubings and fittings
- Level sensors
- Microfluidic chip of your choice
- ESI Software (Elveflow)
- User guide
