It can be difficult to find a good pair of centioles. These are two cylindrical shaped organelles arranged perpendicular to each other composed of microtubules. They are located in the centrosome of the cell and are associated with cell division. Finding a complete pair is rare since there are only two of them in a cell and we are looking at a roughly 50 nanometer thick slice of a cell that is 20 microns thick (about 400 times thicker than the section).

These were found in Lymphocytes from a mouse Lymph Node. The Lymph Node was processed by Jaime Lladora of the NYU Skirball Institute. The images were gathered on a Philips CM12 Transmission Electron Microscope and a Gatan 4k x 2.67k digital camera.
