新兴的组织转化技术为原位研究系统水平的分子和解剖特征提供了前所未有的机会。基于水凝胶的方法设计物理化学组织特性,使完整的器官光学透明,大小和形状可调,同时将生物分子保留在其生理位置。当与先进的分子工具,标记和成像技术相结合时,组织转化能够以更快的速度和分辨率对分子,细胞及其相互关系进行三维(3D)映射。在这篇综述中,我们讨论了组织转化和标记技术的基本工程原理,以及它们的广泛应用,当前的挑战和未来的潜力。基于水凝胶的组织转化技术的原理、应用、挑战和未来,它扩大了完整器官中生物分子成像的限制。
Emerging tissue transformation technologies provide an unprecedented opportunity to investigate system-level molecular and anatomical features in situ. Hydrogel-based methods engineer physicochemical tissue properties to render intact organs optically transparent, size- and shape-adjustable while preserving biomolecules at their physiological locations. When combined with advanced molecular tools, labeling, and imaging techniques, tissue transformation enables three-dimensional (3D) mapping of molecules, cells, and their interrelationships at increasing speeds and resolutions. In this review, we discuss the basic engineering principles of tissue transformation and labeling techniques, as well as their broad applications, current challenges, and future potential. The principles, applications, challenges and future of hydrogel-based tissue transformation technologies, which have expanded the limits of biomolecular imaging in intact organs.
