气管上皮细胞增生与修复是对损伤的一种基本反应过程。对损伤后气管上皮细胞的增生与分化的正确理解,在肺癌的组织发生研究中是不可缺少的。非手术气管粘膜损伤技术为制造这种损伤提供了一种理想的方法,现介绍如下; 选市售V_2型静脉留置针,长70 mm,进行改造。首先,取出不锈钢的内针,去除针尖约1mm最尖锐部分,然后,使 Tracheal epithelial cell proliferation and repair of damage is a basic reaction process. Correct understanding of the proliferation and differentiation of tracheal epithelial cells after injury is indispensable in the study of the carcinogenesis of lung cancer. Non-surgical tracheal mucosal injury technology for the manufacture of such damage provides an ideal method, are described below; optional V_2 type venous catheter sale, length 70 mm, to transform. First, remove the stainless steel inner needle, remove the needle tip of the most sharp part of about 1mm, and then
