Lotus tetragonolobus lectin (LTL) was used to identify differentiated proximal tubule and nearly all of the LTL+ cells were also tdTomato+. No tdTomato+ cells were LTL−, indicating that the SLC34a1GCE driver is absolutely specificto proximal tubule (Fig. 1B).

The most distinctive characteristic of the proximal tubule is its luminal brush border. The luminal surface of the epithelial cells of this segment of the nephron is covered with densely packed microvilli forming a border readily visible under the light microscope giving the brush border cell its name. The microvilli greatly increase the luminal surface area of the cells, presumably facilitating their reabsorptive function as well as putative flow sensing within the lumen. income tax efiling pdf passwordWebThe proximal convoluted tubule is responsible for reclaiming almost all of the filtered bicarbonate, glucose, and amino acids, as well as 40% or more of the filtered sodium, … income tax efiling refund statusWebThe tubule compartments of the nephron include: the proximal tubule (convoluted and straight), the descending tubule, the ascending tubule, the loop of Henle, the distal tubule (early and late) and the collecting duct.
