Analysis of Capillary-like Structures Formed by Endothelial Cells in a Novel Organotypic Assay Developed from Heart Tissue

چکیده
In this work, we present an algorithm to perform automatic segmentation, feature extraction and dosage classification of images derived from a novel organotypic angiogenesis assay developed to assess the effects of ionising radiation in the mouse heart. The images presented very different conditions of illumination and conditions of density and shapes of cells. The algorithm consists of a pipeline of several steps, which were validated against hand-segmented images. The algorithm provided satisfactory results, as all images were correctly dose-classified. The cells exposed to the lowest radiation dose were observed to have the greatest relative feature variability.

Background Endometriosis is the presence of endometrial tissue outside of the uterine cavity and is the most common gynecologic disorder in women of reproductive age. We have preliminary evidence that in the presence of a 3-dimensional (3-D) fibrin matrix, human endometrial glands, stroma, and neovascularization can develop in vitro, mimicking the earliest stages of endometriosis. The aim of th...
متن کامل3D study of capillary network derived from human cord blood mesenchymal stem cells and differentiated into endothelial cell with VEGFR2 protein expression
New blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ECs) which in turn give rise to primitive capillary network. Human cord blood (HCB) contains large subsets of mononuclear cells (MNCs) that can be differentiated into endothelial-like cells in vitro. Human mononuclear progenitor cells were purified from fresh umb...
متن کاملCapillary Network Formation by Endothelial Cells Differentiated from Human Bone Marrow Mesenchymal Stem Cells
Human bone marrow derived mesenchymal stem cells (HBMSCs) have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. In this study, the differentiation of hBMSCs into endothelial like-cells was induced in presence of vascular endothelial growth factor (VEGF) and insulin-like growth factor (IGF-1). The differentiated endothelial cells were exam...
متن کاملSpecification of Hemato-Endothelial-Like Structures and Generation of Hematopoietic Progenitor Cells from Human Pluripotent Stem Cells
Background and purpose: Human pluripotent stem cells (hPSCs) with the ability to differentiate into adult cells have provided a new perspective for treatment of some diseases. But, the efficiency of differentiation methods to generate hematopoietic progenitor cells (HPCs) is faced with multiple challenges. In the present study, we investigated the formation of hemato-endothelial-like structure...
