Provided is a method for preparing a tissue section, including treating a tissue specimen with a clearing agent and at least one labeling agent to obtain a cleared and labeled tissue specimen; generating a three-dimensional (3D) image of the cleared and labeled tissue specimen; performing an image slicing procedure on the 3D image to generate a plurality of two-dimensional (2D) images; identifying a target 2D image among the plurality of 2D images to obtain a distance value of D1, which indicates the distance between the target 2D image and a predetermined surface of the 3D image; preparing a hardened tissue specimen from the cleared and labeled tissue specimen; and cutting the hardened tissue specimen near a predetermined site to obtain a tissue section, wherein the distance between the predetermined site and a surface of the hardened tissue specimen corresponding to the predetermined surface of the 3D image is D1.

Method for preparation of tissue sections

Provided is a method for analyzing a tissue specimen, including treating a tissue specimen with an aqueous clearing agent and with at least two fluorescent probes to obtain a cleared and labeled tissue specimen; imaging the cleared and labeled tissue specimen to generate a three-dimensional (3D) image of the tissue specimen; preparing a stained tissue section from the cleared and labeled tissue specimen; capturing a reference two-dimensional (2D) image of the stained tissue section; matching the reference 2D image with the 3D image to extract from the 3D image a series of 2D image slices including a corresponding 2D image slice that corresponds to the reference 2D image; and determining at least one pathological score for each of the series of 2D image slices and reporting the presence or absence and the extent of the disease based on the pathological scores. The method can improve the accuracy of histopathologic diagnosis.
