Abstract

The micropatterning of rat primary hepatocyte hetero-spheroids was prepared on microfabricated glass substrates coated with poly(ethylene glycol) (PEG) brushes. Co-cultivation of hepatocytes and endothelial cells was used to stabilize hepatocyte viability and liver-specific functions. Rat primary hepatocytes, suspended in a culture medium, were applied to the patterned dishes with cultured endothelial cells selectively located in the circular domains. Rat primary hepatocytes formed spheroids within 24-h only on the circular regions of existing endothelial cells, generating a two-dimensional (2D)-arrayed structure of the hepatocyte spheroids.
