| Research Abstract |
We prepared a panel of monoclonal antibodies for cell surface proteins on various liver cells, and developed culture systems using isolated cell populations. By applying those tools we characterized fetal liver hepatoblasts and adult liver stem/progenitor cells. We also characterized sinusoidal endothelial cells and stellate cells that constitute sinusoids. Liver mesothelial cells were also isolated and shown to support proliferation of fetal hepatocytes. Transcription factors and cell membrane proteins involved in hepatocyte differentiation were also identified and characterized.
