Abstract

Valid quantification of organ volume and total cell numbers are crucial parameters for morphometric studies. The number of a specific cell type cannot be simply deduced from the number of its profiles found in thin tissue sections, as this parameter also depends on cell volume, tissue orientation as well as tissue atrophy. Design-based stereology has become the method of choice for unbiased, reproducible total cell number quantification. Steps described in this protocol include transcardial perfusion of mice, postfixation, and cryoprotection of the region of interest (ROI), followed by the preparation of a systematically and randomly sampled series of thick sections through the entire ROI. Furthermore, it is described how to perform immuno-histochemical staining of such thick cryo-sections, followed by providing a guidance for quantification of the ROI volume, the generation of unbiased virtual counting spaces, and steps to work with these counting spaces to obtain an unbiased estimate of total cell numbers.
