Abstract
COS-7 cells, fixed with glutaraldehyde, were studied using the transmission X-ray microscope at the electron storage ring BESSY, Berlin. The border of the cell, the nucleus, nucleoli and mitochondria of the cells were clearly visualized with the X-ray microscope. In addition, we found many X-ray dense granules preferentially located around the nucleus. Electron microscopy showed that numerous multivesicular bodies, whose structures belong to the endosome–lysosomal system, were present around the nucleus. The size and localization patterns of the X-ray dense granules were quite similar to those of multivesicular bodies. These results strongly suggest that the X-ray dense granules are multivesicular bodies.
