Abstracts ABSTRACT FINAL ID: 2469 Poster Board -101 TITLE: Human Microvascular 3-D Spheroid Model for Toxicity Testing AUTHORS (FIRST INITIAL, LAST NAME): J. K. Das1, Q. H. Felty1 INSTITUTIONS (ALL): 1. Environmental & Occupational Health, Florida International University, Miami, FL, United States. KEYWORDS: Human Vascular Spheroids, Proliferative Lesions, ID3 ABSTRACT BODY: Proliferative microvascular lesions that result from a focal budding of endothelial cells are an aggressive endothelial phenotype that may be modified by exposure to persistent environmental pollutants. The goal of this study was to establish a “Vascular Sphere in Dish model” for toxicity screening based on human vascular cells for the purpose of creating a biologically relevant in vitro model. We developed a method for preparing a 3-dimensional (3-D) vascular spheroid model that consisted of combining human microvascular endothelial cells, human vascular smooth muscle cells, and human fibroblasts. Our procedure cultured the combination of cells in specified ratios in an ultra-low attachment culture dish in B27 media to form the vascular spheres. Next, these spheres were transferred into a dish and cultured for up to 28 days without B27 supplement in a defined fibrin matrix seeded with fibroblasts and maintained in a culture medium comprised of DMEM/F12 and growth supplements. Our data showed that human vascular spheres imitate proliferation and tube formation in vitro. The ability of microvascular endothelial cells to sprout and form stable vascular networks in fibrin matrices was also investigated as a function of vascular stemness. We have previously studied the inhibitor of DNA binding and differentiation protein 3 (Id3). Under defined cell culture conditions, endothelial spheroids that overexpressed ID3 showed an increase in stem cell markers CD34 and VEGFR3; and formed a 3-D vascular tissue that morphologically resembled glomeruloid microvascular lesions.
