Primary hepatocyte culture is a valuable tool that has been extensively used in basic research of liver function, disease, pathophysiology, pharmacology and other related subjects. The method based on two-step collagenase perfusion for isolation of intact hepatocytes was first introduced by Berry and Friend in 1969 and, since then, has undergone many modifications. The most commonly used technique was described by Seglenin 1976. Essentially, hepatocytes are dissociated from anesthetized adult rats by a non-recirculating collagenase perfusion through the portal vein. The isolated cells are then filtered through a 100 μm pore size mesh nylon filter, and cultured onto plates. After 4-hour culture, the medium is replaced with serum-containing or serum-free medium, e.g. HepatoZYME-SFM, for additional time to culture. These procedures require surgical and sterile culture steps that can be better demonstrated by video than by text. Here, we document the detailed steps for these procedures by both video and written protocol, which allow consistently in the generation of viable hepatocytes in large numbers.
原代肝细胞培养是一种有价值的工具,已广泛应用于肝功能、疾病、病理生理学、药理学及其他相关学科的基础研究。1969年,Berry和Friend首次介绍了基于两步胶原酶灌注法分离完整肝细胞的方法,自那时起,该方法经历了多次改进。最常用的技术由Seglenin于1976年描述。本质上,通过门静脉进行非循环胶原酶灌注,将肝细胞从麻醉的成年大鼠中分离出来。然后将分离的细胞通过孔径为100μm的尼龙滤网过滤,并接种到培养板上。培养4小时后,用含血清或无血清培养基(如HepatoZYME-SFM)更换培养基,继续培养一段时间。这些操作需要手术和无菌培养步骤,用视频展示比文字更能说明问题。在这里,我们通过视频和书面方案记录了这些操作的详细步骤,这使得能够持续大量生成有活力的肝细胞。
