Isolation and characterization of normal and neoplastic colonic epithelial cell populations.

abstract：BACKGROUND & AIMS:Studies on the early steps in the life cycle of hepatitis B virus have been hampered by the lack of readily available target cells. In this study, we mapped a defined virus attachment site to primary hepatocytes that is essential for infection. METHODS:We used purified virus particles from human carr...
