¹Materials Science and Engineering, CSIRO

We describe the use of the monoclonal antibodies TG30 (CD9) and GCTM-2 for the combined detection of cell surface antigens via fluorescence activated cell sorting (FACS) for the identification and enrichment of live human embryonic stem cells (hESC) using positive selection and also the use of negative selection to purge hESCs from a mixed cell population.

This manuscript describes a detailed protocol for Hepatitis B virus (HBV) infection in novel engineered 293T cells (293T-NE-3NRs, expressing human NTCP, HNF4α, RXRα and PPARα) and traditional hepatic cells (HepG2-NE, expressing human NTCP).

An Efficient Method for Directed Hepatocyte-Like Cell Induction from Human Embryonic Stem Cells

Qi Zhou^*1,2,3, Xiaoling Xie^*1,2,3, Zhiqian Zhong^1,2,3, Pingnan Sun^1,2,3, Xiaoling Zhou^1,2,3

This manuscript describes a detailed protocol for differentiation of human embryonic stem cells (hESCs) into functional hepatocyte-like cells (HLCs) by continuously supplementing Activin A and CHIR99021 during hESC differentiation into definitive endoderm (DE).
