Liver-specific function of primary hepatocytes cultured on the gel microwells of varying components. PEG microwell on pure glass (P/G), heparin gel microwell on pure glass (H/G), PEG microwell on heparin gel layer (P/H), heparin microwell on heparin gel layer (H/H). A) ELISA analysis of albumin secretion and B) urea synthesis by hepatocytes at various time points during 7 day culture. Error bars indicate standard deviation of the mean for n = 3 samples. Significance; * p < 0.05, ** p < 0.001.
