有多种因素影响隔离的结果9,10。其中，消化胰腺组织中起着突出的作用。基于我们自己的人胰岛隔离的经验，我们总结了以下关键点，这有可能影响胰岛的产量和质量。 <ol><li>时利用不同类型的酶，消化时间是不同的。 </li><li>只要完全从胰腺组织中分离胰岛的40-50％，消化应立即停止加入稀释液，冷却下来的组织。 </li><li>柔和的组织处理，收集，洗涤，和混合。 </li><li>收集组织和UW液的混合?...

human pancreatic islet isolation: part i: digestion and collection of pancreatic tissue

1型糖尿病的管理负担，既要对个人和社会，每年耗资超过100亿美元。尽管血糖监测和新的胰岛素制剂的广泛使用，许多人仍然发展毁灭性的继发性并发症。胰岛移植可以恢复接近正常的糖尿病患者血糖控制<sup&gt; 1</sup&gt;胰岛素强化治疗相关的严重的低血糖发作的危险，没有。胰岛移植成功的，重要的是提供足够的胰岛质量。但是，捐助者的特点，器官获取和保存的影响隔离的结果<sup&gt; 2</sup&gt;。我们在美国伊利诺伊大学芝加哥分校（UIC）的开发与改进的净化梯度，成功的隔离协议<sup&gt; 3</sup&gt;。该计划开始于2004年1月，2008年11月超过300隔离。 “胰腺被送往在冷保存液（UW液，威斯康星州或HTK的大学，组氨酸，色氨酸酮戊二酸）<sup&gt; 4-7</sup&gt;在UIC的细胞分离胰岛隔离的实验室。使用UIC的方法，这是最初所Ricordi描述的方法修改后的版本中分离出胰岛<em&gt;等</em&gt;<sup&gt; 8</sup&gt;。简言之，清洗后的胰腺周围组织灌注与酶液（赛瓦胶原酶+中性蛋白酶或Sigma V酶）。扩张的胰腺，然后转移到Ricordi消化腔，连接到一个修改过的，封闭的的循环管路系统，并升温至37 ° C。在消化，香港总商会是轻轻的动摇。样品连续监测的消化进度。一旦获得了自由的胰岛细胞，在显微镜下发现，消化停止刷新冷（4℃）的RPMI稀释液稀释的酶进入流通系统（Mediatech，赫恩登，VA）。正在收集和M199媒体补充人血白蛋白洗净后，组织样本进行预净化计数和培养威斯康星解决方案之前，净化。第二部分：人类胰岛的分离纯化及文化，净化过程中，将描述。
