Portrait in the electron microscope: E.T. lives on!

Border cell cluster in drosophila egg chamber was showed. Drosophila ovaries were embedded in Epon and cut into 70nm ultra-thin sections. The contrast of cell membrane structure was enhanced by reduced osmium fixation. Sections were viewed directly in the electron mi­croscope without further staining. The image was recorded in an FEI Morgagni operating at 80kV with magnification at 2200×.
