CLARITY是一种新型的组织清理技术,可将完整的生物组织转化为纳米多孔水凝胶-组织混合体,同时保留解剖结构、蛋白质和核酸。去除脂质后,水凝胶结构是透明的,并允许进行几轮免疫染色和成像。这项技术为研究人员检查完整的中枢神经系统(即小鼠大脑和脊髓)提供了一种理想的方法。CLARITY被《科学》杂志选为2013年的十大突破之一。然而,原有的CLARITY技术仍然存在严重的技术局限性,阻碍了其在更广泛领域的应用。因此,出现了许多基于CLARITY的修正清算方法。由于所有基于clarity的组织清除技术都涉及类似的程序,因此本综述试图将这些方法划分为单独的程序,以便提供测试和组合组织清除方法的新方法。此外,清除方法的组合可以帮助确定清除和成像大样本的最佳方法。
CLARITY is a novel tissue clearing technique that transforms intact biological tissues into a nanoporous hydrogel-tissue hybrid, preserving anatomical structures, proteins and nucleic acids. The hydrogel-based structure is transparent after the removal of lipids and permits several rounds of immunostaining and imaging. This technique provides an ideal way for researchers to examine the central nervous system (i.e., mouse brain and spinal cord) intact. CLARITY was selected as one of ten breakthroughs in 2013 by Science. However, the original CLARITY technique still has severe technical limitations which impede its application in wider fields. Therefore, many modified clearing methods based on CLARITY have emerged. As all CLARITY-based tissue clearing techniques involve similar procedures, the present review attempted to divide these methods into individual procedures in order to provide new ways to test and combine tissue clearing methods. Furthermore, the combination of clearing methods could help to determine the optimal method for clearing and imaging large samples.
