中文摘要
我们制备了一组针对不同肝细胞表面蛋白的单抗,并利用分离的细胞群体开发了培养系统。通过应用这些工具,我们确定了胎儿肝脏、肝母细胞和成人肝脏干细胞/祖细胞的特征。我们还对构成正弦的血管内皮细胞和星状细胞进行了表征。肝间皮细胞也被分离出来,并被证明支持胎肝细胞的增殖。此外,还鉴定了与肝细胞分化相关的转录因子和细胞膜蛋白。
英文摘要
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.
