Project description:We have developed an endovascular micro-endomyocardial biopsy device (Micro-EMB) with an outer diameter of 0.4 mm in order to minimize procedural risk, sampling trauma, and increase sampling specificity compared to conventional EMB. Here, we have taken micro-EMB samples from swine myocardium before, during and after myocardial infarction to detect potential gene expression responses.
Project description:15 Subjects were sampled using ingestible sampling device. Device sampled regions of the small intestine depending on design of sampling device.
Project description:We have developed an endovascular catheter-based device for sampling of the endothelium, intended for RNA-seq analysis. With an outer diameter of 0.23 mm it is capable of reaching peripheral vessels for endothelial sampling, and favourably compares to other approaches with stent retrievers or similar tools. Here, we have collected samples from liver and kidney vessels from swine and performed RNA-sequencing to validate the sample quality.
Project description:Endomyocardial biopsy (EMB) is the gold standard for diagnosis of several heart diseases, yet its use is limited by relatively low diagnostic yield and significant complication risks. To address this, we have developed an endovascular micro-biopsy (Micro-EMB) device with an outer diameter of 0.4 mm in order to minimize procedural risk, sampling trauma, and increase sampling specificity. We have performed RNA-seq on the resulting submilligram tissue as well as controls. The gene expression signatures were compared between Micro-EMBs and conventional EMB controls, as well as negative controls such as blood and skeletal muscle.
Project description:15 human subjects were sample using an ingestible sampling device to target specific regions of the small intestine by using different capsule types (capsule types 1 to 4). Stool was also analyzed.
