Zebrafish Entrapment By Restriction Array (ZEBRA) device: a low-cost, agarose-free zebrafish mounting technique for automated imaging.

The zebrafish has emerged as a useful model system for a variety of studies, including the investigation of inflammation and immunity. However, current zebrafish imaging techniques, such as agraose mounting, can be time-consuming and detrimental for long-term imaging. Alternatively, automated sorting and imaging systems can be costly and/or complicated to assemble.

Tubeless microfluidic angiogenesis assay with three-dimensional endothelial-lined microvessels.

The study of angiogenesis is important to understanding a variety of human pathologies including cancer, cardiovascular and inflammatory diseases. In vivo angiogenesis assays can be costly and time-consuming, limiting their application in high-throughput studies. While traditional in vitro assays may overcome these limitations, they lack the ability to accurately recapitulate the main elements of the tissue microenvironment found in vivo, thereby limiting our ability to draw physiologically relevant biological conclusions.
