There are a lot of problems to be resolved about performance of membrane materials, methods of hepatocytes' culture fit for BAL and efficiency of hollowfiber reactor in the research of BAL.
The tissue culture of mumps virus S79 strain was purified by ultrafiltration on hollowfiber, PEG precipitation and density gradient ultracentrifugation.
Conclusion The hollowfiber bioreactor for culturing pig hepatocytes can. be prepared by artificial capillary cell culture system, which provides a certain liver-specific function in 1 week.
