一种简单的方法,避免了使用无钙缓冲液,水解酶和洗涤剂灌注已被开发,以获得新鲜的肝细胞从门静脉周围和肝小叶的中央周围区域。用微穿孔器从新鲜或灌注的肝脏中收集大鼠肝小叶门静脉周围和中央周围区域的圆柱形栓塞(200 × 500微米),重约1 mg。根据台盼蓝染色评估,90%的细胞是完整的。谷氨酰胺合成酶活性检测主要是(约。85%),表明该方法允许选择性收获肝小叶的纯小叶下区。在25°C下,通过顺行灌注的肝脏栓塞测量的氧摄取率分别为56 ± 5和33 ± 7μmol/g/h(门静脉周围和中央周围栓塞),与完整器官获得的数据相似。这种方法提供了新的机会来研究在接近生理条件下小叶下细胞的基本代谢过程的调节。
A simple method which avoids the use of perfusion with calcium free buffer, hydrolytic enzymes and detergents has been developed to obtain fresh hepatocytes from periportal and pericentral regions of the liver lobule. Cylindrical plugs (200 × 500 microns) of periportal and pericentral areas of the rat liver lobule weighing about 1 mg were collected with a micropunch from fresh or perfused liver. Ninety percent of cells were intact as assessed from trypan blue staining. Glutamine synthetase activity was detected predominantly (ca. 85%) in plugs isolated from pericentral regions indicating that this method allows selective harvesting of pure sublobular zones of the liver lobule. Rates of oxygen uptake measured at 25°C by plugs from livers perfused in the anterograde direction were 56 ± 5 and 33 ± 7μmol/g/h by periportal and pericentral plugs, respectively, values similar to data obtained from the intact organ. This method provides new opportunities to study the regulation of basic metabolic processes in cells from sublobular areas under nearly physiological conditions.
