We describe the generation of microfluidic platforms for the co-culture of primary hepatocytes and endothelial cells; these platforms mimic the architecture of a liver sinusoid. This paper describes a progressional study of creating such a liver sinusoid on a chip system. Primary rat hepatocytes (PRHs) were co-cultured with primary or established endothelial cells in layers in single and dual microchannel configurations with or without continuous perfusion. Cell viability and maintenance of hepatocyte functions were monitored and compared for diverse experimental conditions. When primary rat hepatocytes were co-cultured with immortalized bovine aortic endothelial cells (BAECs) in a dual microchannel with continuous …

We have developed a novel microfluidic device using poly-dimethylsiloxane (PDMS) microchannels for long term, layered co-culture of primary rat hepatocytes (PRH) and endothelial cells (EC) to mimic the liver sinusoid. Three microfluidic configurations were investigated as shown in Figure 1. In configuration 1, where PRH and rat adrenal medullary endothelial cells (RAMEC) were cocultured with matrigel in layers in a single PDMS microchannel, cells remained viable for 30 days. In configuration 3, where PRH and liver sinusoidal endothelial cells (LSEC) were cultured on the opposite sides of the microporous membrane between two microchannels under static and dynamic conditions, PRH retained …
