CELL TISSUE AND IMAGING CORE

在过去的资助期间，细胞培养核心继续提供小鼠和 正常和病变肝脏的大鼠肝细胞、细胞系和人类肝细胞的分布。一个 单独资助(从2001年年中开始通过NIAAA)非实质性肝细胞核心提供新鲜 分离培养正常或病变大鼠Kupffer细胞、肝星状细胞和肝窦内皮细胞 细胞。从2004年9月1日起，细胞培养核心停止准备人类肝细胞，而是分配给 由商业来源(CellzDirect，Tucson，Az)制备的人肝细胞。这是因为一个 南加州大学的肝脏外科医生和支持肝脏组织的CellzDirect达成了协议 并向肝脏中心的研究人员免费提供人类肝细胞。 细胞培养核心继续为中心成员提供至关重要的服务，并已 从前一个授权周期到当前授权周期在使用方面保持接近稳定状态(准备次数， (调查员和补助金)和生产力(出版物数量)。十六名会员及附属会员 使用1998年至2003年的细胞培养核心，发表了47篇论文。在本周期中，2003年至2008年，18个满额 成员使用核心，并制作了50份出版物。特别是，细胞培养核心已经被 有助于帮助年轻研究人员建立他们的独立研究计划(例如，惠普 杨丁汉、季振中、刘振星)。

During the past funding period, the Cell Culture Core has continued to provide isolation of mouse and rat hepatocytes from normal and diseased livers, cell line banking, and distribution of human hepatocytes. A separately funded (through NIAAA beginning in mid-2001) Non-parenchymal Liver Cell Core provides freshly isolated and cultured normal or diseased rat Kupffer cells, hepatic stellate cells, and sinusoidal endothelial cells. Effective 9/1/04, the Cell Culture Core stopped preparing human hepatocytes but instead distributes human hepatocytes prepared by a commercial source (CellzDirect, Tucson, Az). This is because an agreement was made between the USC liver surgeons and CellzDirect, which supports the liver tissue repository at USC and provides human hepatocytes free of charge to Liver Center investigators. The Cell Culture Core has continued to provide a vital service to the Center members and has remained near steady state from the previoijs to the current grant cycle in terms of usage (number of preps, investigators and grants) and productivity (number of publications). Sixteen members and affiliated members used the Cell Culture Core from 1998 to 2003 with 47 publications. In the current cycle, 2003 to 2008, 18 full members used the Core and generated 50 publications. In particular, the Cell Culture Core has been instrumental in assisting young investigators in establishing their independent research programs (e.g. H.P. Yang, D. Han, C. Ji and Z.X. Liu).
