Tissue clearing renders entire organs transparent to accelerate whole-tissue imaging; for example, with light-sheet fluorescence microscopy. Yet, challenges remain in analyzing the large resulting 3D datasets that consist of terabytes of images and information on millions of labeled cells. Previous work has established pipelines for automated analysis of tissue-cleared mouse brains, but the focus there was on single-color channels and/or detection of nuclear localized signals in relatively low-resolution images. Here, we present an automated workflow (COMBINe, Cell detectiOn in Mouse BraIN) to map sparsely labeled neurons and astrocytes in genetically distinct mouse forebrains using mosaic analysis with double markers (MADM). COMBINe blends modules from multiple pipelines with RetinaNet at its core. We quantitatively analyzed the regional and subregional effects of MADM-based deletion of the epidermal growth factor receptor (EGFR) on neuronal and astrocyte populations in the mouse forebrain. COMBINe performs automated cell detection based on morphology and color COMBINe accurately detects out-of-focus cells in tissue-cleared brains COMBINe overcomes slight misalignments between color channels Hierarchical analysis reveals regional effect of sparse Egfr deletion on astrocytes Tissue clearing has been extensively used to explore cellular organizations in intact organs. By imaging entire mouse brains with cellular resolution, the resulting datasets contain terabytes of images to process and millions of labeled cells that need to be counted and classified based on morphology and color. Therefore, automation of data processing and analysis is an urgent need. We present a workflow (COMBINe) to automatically locate and classify labeled cells in such 3D datasets and to quantitatively analyze the regional effects after registration to the referenced Allen Brain Atlas. We applied the approach to study the effects of sparse epidermal growth factor receptor deletion on gliogenesis. Cai et al. present a workflow called COMBINe to automatically detect and quantify all labeled cells in tissue-cleared mouse brains and apply it to study the effects of sparse epidermal growth factor receptor deletion. COMBINe is adaptable for various neuroscience projects that require whole-brain quantification and analysis.
