Histological study of kidney tissues from humans and animal models can reveal important information about kidney disease and injury, as well as toxicologic effects of drugs and chemicals. In this masterclass webinar, North American Director of Life Sciences Applications, Adam Smith, will discuss approaches for analyzing kidney tissues stained with H&E, immunohistochemistry, and histochemical assays using HALO image analysis modules and HALO AI. This webinar will focus on the macro- and micro-segmentation of the kidney in order to limit analysis results to the desired regions of interest, such as tubules or glomeruli. We will also look at ways to leverage tools within HALO to create HALO AI Classifiers more efficiently.
