Agarose Cell Block: Innovated Technique for the Processing of Urine Cytology for Electron Microscopy Examination

Abstract

Easy manipulation and preservation of cells in suspension through the different steps of sample processing for electron microscopy examination is essential for proper diagnosis. The author used agarose gel as an embedding media for processing cells in suspension for electron microscopic examination. The AgarCyto cell block procedure of Kerstens et al. (J Histochem Cytochem. 2000; 48: 709—718) was used to begin electron microscopic processing of exfoliated urothelial cells in voided urine or cells in suspension. Processing of agarose cell block simultaneously for light and electron microscopic examination represents a great advantage offered by this innovated technique.
