Scanning electron micrograph montage of cultured HeLa cells. This image is a montage of six overlapping fields of view, each photographed at 2,231x with a 17.8mm working distance and an accelerating voltage of 12.5kV. The cells were grown to confluence on Thermanox® coverslips and fixed with glutaraldehyde and osmium tetroxide, then critical point dried. These cells were imaged using an FEI Quanta 200 scanning electron microscope. Rounded, non-adherent cells are most likely mitotic, and the two adjacent, spherical cells near the lower left corner have almost completed cytokinesis. Scale bar = 10µm.
