Objective: To probe into the physical and chemical property, biology activity,acute and chronic toxicity of low molecular weight natural tumor suppressor (LMW NTS)of fetal bovine hepatocytes.

Immunology research on human fetal liver cells transplantation in treatment of metabolic diseases;

We study the separation, culture, inducing differentiation and tansplantation of human fetal liver cells through t.

METHODS: Fetal hepatocytes isolated from 3-week SD rat fetuses bred were transplanted into the spleens of liver regeneration model rats with 70% partial hepatectomy.

To study the effects of 70%Hepatectomy on the proliferation of rat fetal hepatocytes after intrasplenical transplantation, fetal hepatocytes isolated from 3 week SD rat fetuses bred were transplanted into the spleens of liver regeneration model rats with 70% partial hepatectomy.

Development of the technique for isolation and primary culture of bovine hepatocytes

Primary human fetal hepatocytes with HBV infection in vitro;

Methods Human fetal hepatocytes were separated by four-step perfusion method.

Orientation researches were carried out to confirm whether human fetal hepatocytes (HFH) might be infected with hepatitis C virus (HCV) after co culturing with HCV positive serum in vitro for 24 h.
