Abstract
Thermo-responsive poly(N-isopropylacrylamide) (PIPAAm) was covalently patterned by masked el electron beam irradiation. Introduction of PIPAAm on tissue culture polystyrene dish was confirmed by ATR-FTIR and ESCA measurements. Hepatocytes were cultured at $37^{circ}C$ on these surfaces. Cells adhered on PIPAAm-grafted domains were detached by reducing culture temperature to $20^{circ}C$. Endothelial cells were then seeded and cultured on the same surfaces. Seeded endothelial cells were selectively attached on hepatocytes detached and PIPAAm-grafted domains and could be co-cultured with hepatocytes on the same culture dishes with clear pattern. This co-culture method enabled long-term co-culture of hepatocytes with endothelial cells.
