snRNA-seq provides less biased cellular coverage, does not appear to suffer cell isolation-based transcriptional artifacts, and can be applied to archived frozen specimens. The HiTMiN assay presented here greatly increases the suitability of the MN assay as a quick, affordable, sensitive and accurate assay to measure genotoxicity of environmental samples in different cell lines. Transcriptomic profiling of complex tissues by single-nucleus RNA-sequencing (snRNA-seq) affords some advantages over single-cell RNA-sequencing (scRNA-seq).

Here, we describe how to adapt CellProfiler to analyze cross sections of xylem tissue and use it to gather a variety of information on traits such as cell size, shape, and number.
All compounds tested induced MN formation below cytotoxic concentrations. CellProfiler is a free, open source program that allows researchers to automate image analysis and collect large amounts of phenotypic data relatively easily.
3D confocal microscopy stacks of stained intracellular lipids and nuclei were acquired, 2D cellular outlines were. The assay was validated through exposure to two inorganic (chromium and cobalt) and one organic (the herbicide metolachlor) compounds, which are genotoxicants of concern in the marine environment. aggregated low-density lipoprotein (LDL). The data can be downloaded from the Image Data Resource.

Image analysis using both commercial (Columbus) and freely available (CellProfiler) software automated the scoring of MN, with improved precision and drastically reduced time compared to manual scoring and other available protocols. Membrane-less organelle in the nucleus of the cell Functions: ribosome biogenesis and cell cycle regulation.image-55 Speaker Notes In the DNA channel, the nucleoli is shown as the absence of DNA (red arrows). In this study, we optimised and streamlined the HiTMiN assay, adapting the MN assay to a miniaturised, 96-well plate format with reduced steps, and applied it to both primary cells from green turtle fibroblasts (GT12s- p) and a freshwater fish hepatoma cell line (PLHC-1). High-throughput evaluation with automated image analysis could reduce subjectivity and increase accuracy and throughput. However, evaluating chromosomal damage in the MN assay through manual microscopy is a highly time-consuming and somewhat subjective process. Because manual immunohistochemical analysis of features such as skeletal muscle fiber typing, capillaries, myonuclei, and fiber size-related parameters is time consuming and prone to user subjectivity, automatic computational methods could allow for faster and more objective evaluation. It provides an efficient assessment of chromosomal impairment due to either chromosomal rupture or mis-segregation during mitosis. These can be grouped together into 7 feature groups- AreaShape, Correlation, Granularity, Intensity, Neighbors, RadialDistribution, and Texture. size of nucleus, diameter of nucleus) are measured per cell using the free, open-source software CellProfiler. One of the most commonly used methods to evaluate genotoxicity in exposed organisms is the micronucleus (MN) assay. Level 2 - Image analysis - Image analysis of 1700 computed features (e.g. Anthropogenic contaminants can have a variety of adverse effects on exposed organisms, including genotoxicity in the form of DNA damage.
