ORGAN ON A CHIP
+
q The convergence of Lab-on-Chips and cell biology has
permitted the study of human physiology in an organ-specific
context, introducing a novel model of in vitro multicellular
human organisms.
q An Organ-on-a-Chip is a multi-channel 3-D microfluidic cell
culture chip that simulates the activities, mechanics and
physiological response of entire organs and organ systems.

LIVER ON A CHIP
Identification of the four types of mouse hepatic
cells in an in vitro 3D liver sinusoid liver chip
cultured for 1 day. A–D. Immunostaining of
respective biomarkers for the distinct types of
cells. Hepatocytes stained with E-­‐cadherin (red),
CK pan (green) and nucleus (blue ) are closely
seeded in the lower channel of the assemble d
liver chip.
Intriguingly, co-­‐culture and shear flow enhance albumin secretion independently or
cooperatively, while shear flow alone enhances HGF production and CYP450 metabolism.

The LiverChip® is a multiwell liver-­‐on-­‐a-­‐chi p device
that enables extended (>1 month) maintenan ce of
phenotypically intact three-­‐dimensional primary
human liver cells. It consists of fluidically isolated
wells that house scaffolds for cells to adhere to and
culture in perfused conditions.
Primary rat hepatocytes and stabilizing stromal fibroblasts
in agarose gels. Cells survive at t he gel perimeter and near
perfused channels ( 8 days od culture)
