足细胞损伤是肾小球疾病的标志,如局灶节段性肾小球硬化,通常与明显的蛋白尿和肾脏病理进展相关。足细胞结构异常和丢失也与微小变化疾病和更常见的糖尿病肾病有关。在这里,我们首次应用扫描离子电导显微镜(SICM)技术来评估新分离的人类肾小球的拓扑结构。SICM提供了一个独特的机会来评估肾小球足细胞以及其他肾元结构段与电子显微镜分辨率,但在活体样品。这里展示的是SICM方法在活体肾小球中的应用,这为未来对活细胞膜形态和各种功能参数的动态分析提供了原理证明。
Podocyte damage is a hallmark of glomerular diseases, such as focal segmental glomerulosclerosis, typically associated with marked albuminuria and progression of renal pathology. Podocyte structural abnormalities and loss are also linked to minimal change disease and more common diabetic kidney disease. Here we applied the first‐time scanning ion conductance microscopy (SICM) technique to assess the freshly isolated human glomerulus's topology. SICM provides a unique opportunity to evaluate glomerulus podocytes as well as other nephron structural segments with electron microscopy resolution but in live samples. Shown here is the application of the SICM method in the live human glomerulus, which provides proof of principle for future dynamic analysis of membrane morphology and various functional parameters in living cells.
