Abstract
With the advances in next-generation sequencing and rapid filtering of candidate variants in diseased patients, it has been increasingly important to develop translatable in vivo models to study genetic changes. This allows for functional validation of pathogenic mutations and establishes a system to understand the etiology of disease. Due to the ease of genetic manipulation and rapid ex utero development, the zebrafish has become a valuable resource to study important biological processes, including nephrogenesis. The development and function of the zebrafish pronephros are akin to that of mammals. As such, they offer a tractable model to study kidney disease, especially diabetic nephropathy. However, in order to study kidney dysfunction in zebrafish it is imperative that an appropriate readout is available. The appearance of macro-proteins in patient's urine is indicative of defective kidney function. In this technical chapter, we describe the in vivo use of fluorescently tagged dextrans of different molecular weights to reveal the integrity of the zebrafish glomerular filtration barrier.
