Research Abstract

PEG-GRGDS consisting of polyethylene glycol and arginine-glycine-aspartic acid was prepared. Primary hepatocytes were dispersed by PEG-GRGDS treatment depending on a PEG size. The hepatocytes treated with PEG-GRGDS improved their viability with the cytoskeleton organization, and well expressed albumin production and drug metabolism activities. Therefore, a novel estimation method of cell functions by creating non-adhesive single cell culture technology using PEG-GRGDS was successfully developed.
