Methods:Via a cannula iserted into adominal aorta, Gey's balanced salt solution containing 0.025% collagenase P was perfused into rat normal pancreas. After digestion with collagenase P and protease, Nycodenz density gradient centrifugation was performed to isolate PSC. PSC was identified by its morphology, cytoplasmic lipid droplets and immunocytochemical staining for desmin, GFAP and α-SMA. Results:The production,viability and purity of isolated PSC were（15.3 ± 4.6）× 103／g body weight,（95.0 ± 3.5）%, and ﹥80％ respectively.
