Distribution of Cytoglobin in the Mouse Brain
2016
Cytoglobin (Cygb) is a vertebrate globin with so far poorly defined function. It is expressed in the fibroblast cell-lineage but has also been found in neurons. Here we provide, using immunohistochemistry, a detailed study on the distribution of Cygb in the mouse brain. While Cygb is a cytoplasmic protein in active cells of the supportive tissue, in neurons it is located in the cytoplasm and the nucleus. We found the expression of Cygb in all brain regions, although only a fraction of the neurons was Cygb-positive. Signals were of different intensity ranging from faint to very intense. Telencephalic neurons in all laminae of the cerebral cortex (CCo), in the olfactory bulb (in particular pe…
Dual-beam confocal light-sheet microscopy via flexible acousto-optic deflector
2019
Confocal detection in digital scanned laser light-sheet fluorescence microscopy (DSLM) has been established as a gold standard method to improve image quality. The selective line detection of a complementary metal-oxide-semiconductor camera (CMOS) working in rolling shutter mode allows the rejection of out-of-focus and scattered light, thus reducing background signal during image formation. Most modern CMOS have two rolling shutters, but usually only a single illuminating beam is used, halving the maximum obtainable frame rate. We report on the capability to recover the full image acquisition rate via dual confocal DSLM by using an acoustooptic deflector. Such a simple solution enables us t…
Assessment of Adult Mouse Brain Neuroanatomical Phenotypes Using Quantitative and Precision Histology
2022
Modelling human neurodevelopmental disorders is important in biomedical research since the brain cannot be easily accessed in humans. In this chapter, we describe a series of standardized procedures for the reliable analysis of neuroanatomical phenotypes (NAPs) of the adult mouse brain using quantitative 2D histological practices. Our goal is to provide the reader an experimental pipeline, ranging from experimental work through to data analysis, which can be performed in any academic research setting with or without access to a histology platform. Depending on the type of sections studied, parasagittal or coronal, the assessment of brain neuroanatomy is performed at stereotaxic sections, at…
