CellProfiler allowed rapid high processing capacity of chromogenically stained chronic inflammatory tissue that was reliable, accurate, and reproducible and highlights potential applications in research diagnostics.ĬellProfiler chromogenic image analysis immunohistochemistry oral mucosa. CellProfiler demonstrated versatility with the ability to assess large numbers of images and allowed additional parameters to be quantified. Furthermore, CellProfiler allowed the determination of multiple variables simultaneously, such as area stained and masking to remove any nonstained tissue and white gaps, which also demonstrated reliable agreement (r 2 = >0.9). Scatterplots and Bland-Altman plots demonstrated strong agreement between the manual counters and CellProfiler, with the number of positively stained cells robustly correlating (r 2 = 0.938). Validation comparisons between the manual counters demonstrated strong intra-observer concordance (r 2 = 0.979), particularly when cell numbers were less than 100. Inter-observer and inter-platform agreements were assessed by scatterplots with linear regression and Bland-Altman plots. Digitized images were manually counted and subjected to image analysis in CellProfiler. 5 Biologists typically use CellProfiler to identify objects of interest (e.g. Oral mucosal biopsies from patients with chronic graft-versus-host disease were stained for CD4. CellProfiler can read and analyze most common microscopy image formats. The current investigation aimed to compare CellProfiler quantitative chromogenic IHC analyses against the gold standard manual counting. The open-source digital analysis software, CellProfiler has been extensively used for fluorescently stained cells/tissues however, chromogenic IHC staining is routinely used in both pathological and research diagnostics. Free half-day workshops are held regularly to help researchers learn to construct analyses with CellProfiler.Visual grading of chromogenically stained immunohistochemical (IHC) samples is subjective, time consuming, and predisposed to considerable inter- and intra-observer variations.Guidelines for citing CellProfiler can be found here.Currently has partial support for 3D segmentation however, this is being improved with the latest releases.Limited number of additional modules available online however, additional functionality can be added in-house.Modular design facilitates high-throughput for standardised imaging data.Performs strongly in object-based processing and analysis, such as segmentation of cells stained with multiple fluorophores, colocalisation and shape measurement.Additional modules cover basic image processing, such as application of filters, generation of intensity projections and general image transformations.Object analyses include size, shape, intensity, nearest neighbour distances and tracking.Based on a modular design, where each process or analysis is added to the workflow pipeline. CellProfiler was designed and optimized for the most common high-content screening image format, that is, two-dimensional images.cells and nuclei) within images and image stacks. Software specialising in segmentation and analysis of objects (e.g. CellProfiler goes 3D A new release of CellProfiler the free, open-source quantitative image analysis package developed in the Broad Imaging Platform brings a host of new features, including 3D image analysis.It incorporates many advanced algorithms for accurate segmentation and processing of objects of interest. CellProfiler is pipeline-based image analysis software specialising in object segmentation and measurement. ![]()
