Histology is used to identify structural details of tissue at the microscale in the pathology lab, but analyses remain two-dimensional (2D) as they are limited to the same plane. Nondestructive 3D technologies including X-ray micro and nano-computed tomography (nanoCT) have proven validity to understand anatomical structures, since they allow arbitrary viewing angles and 3D structural detail. However, low attenuation of soft tissue has hampered their application in the field of 3D virtual histology. In a recent study, now published on Scientific Reports, Mark Müller and colleagues at the Department of Physics and Bioengineering have developed a hematein-based X-ray staining method to specifically target cell nuclei, followed by demonstrations on a whole liver lobule of a mouse.
