Fluorescence Micrographs of Fat and Endothelial Cells (image) American Institute of Physics Share Print E-Mail Caption These are fluorescence micrographs of fat and endothelial cells superimposed on differential-interference and phase-contrast images, respectively. The nuclei are stained blue in the micrographs. The image on the right is a picosecond-ultrasonic image of a single endothelial cell with approximately 1-micron lateral and 150-nanometer depth resolutions. Deep blue corresponds to the lowest ultrasonic amplitude. Credit O. Wright/Hokkaido University Usage Restrictions This image may be used only with appropriate caption and credit.
