Abstract: Objective To establish a simple approach for isolating hepatocytes(HCs) from neonatal rats. Methods Multi-step enzymatic digestion and tissue adhering method were used to isolate primary HCs from neonatal rats,and after low-speed centrifugation and selective adherence culture,the HCs were identified by PAS and anti-CK-18 immunocytochemical staining. Results The numbers of separated HCs were about 1-2×106 cells per rat. After 0.4% trypan blue staining,the transient cell activity was >80%,and after cell suspension or tissue block were cultured for 3 to 5 days,the cells spread 70% to 80% of the bottom of each bottle. The purity of the HCs was greater than 95%,and the cell growth were in good condition. Conclusion The primary parenchymal cells of liver obtained were pure and in good activity,which might be used in laboratory for further experiments.
