A three-dimensional vessel-on-chip model to study Puumala orthohantavirus pathogenesis

Project description:Puumala orthohantavirus (PUUV) infection in humans can result in hemorrhagic fever with renal syndrome. Endothelial cells (ECs) are primarily infected with increased vascular permeability as a central aspect of pathogenesis. Historically, most studies included ECs cultured under static two-dimensional (2D) conditions, thereby not recapitulating the physiological environment due to their lack of flow and inherent pro-inflammatory state. Here, we present a high-throughput method for culturing primary human umbilical vein ECs in 3D vessels-on-chip in which we compared host responses of these ECs to those of static 2D-cultured ECs on a transcriptional level. The phenotype of ECs in vessels-on-chip more closely resembled the in vivo situation due to higher similarity in expression of genes encoding described markers for disease severity and coagulopathy, including IDO1, LGALS3BP, IL6 and PLAT, and more diverse endothelial-leukocyte interactions in the context of PUUV infection. In these vessels-on-chip, PUUV infection did not directly increase vascular permeability, but increased monocyte adhesion. This platform can be used for studying pathogenesis and assessment of possible therapeutics for other endotheliotropic viruses even in high biocontainment facilities.

Global expression of mouse hepatocytes cultured as monolayers or as three-dimensional aggregates

Project description:Three-dimensional (3D) culture of hepatocytes leads to improved and prolonged synthetic and metabolic functions, but the underlying molecular mechanisms were unknown. In order to investigate the molecular mechanisms underlying 3D cell-cell interactions in maintaining hepatocyte differentiated functions ex vivo, microarray analyses were performed on primary mouse hepatocytes cultured either as monolayers on tissue culture dishes (TCD) or as 3D aggregates in rotating wall vessel (RWV) bioreactors. Primary hepatocytes were isolated from mice and cultured on TCDs or within RWVs for 4 hours or 24 hours. Freshly isolated hepatocytes (t0) were used as baseline controls. Each experimental condition has three independent biological replicates.

The differences in miRNA expression with miRNA microarrays of two-dimensional (2D)- and three-dimensional (3D)-SNP cells

Project description:Canine mammary gland tumors can be used as predictive models for human breast cancer. There are several types of microRNAs common in human breast cancer and canine mammary gland tumors. The functions of microRNAs in canine mammary gland tumors are not well understood. In the present study, we compared the characterization of microRNA expression in two-dimensional and three-dimensional canine mammary gland tumor cell models. The expression of microRNA-210 in the three-dimensional-SNP cells was 10.19 times higher than that in the two-dimensional-SNP cells.
