Fig. 4. Ultrastructural abnormalities in the CNS of β-Gal−/− mice.
Transmission electron microscopy of spinal cord neurons from 3-month-old β-Gal−/− and β-Gal+/+ mice shows evidence in the affected mouse of an expanded lysosomal compartment with enlarged lysosomes filled with membranous material due to accumulation of GM1-ganglioside. Scale bars: 1 μm; lover right panel 0.5 μm. Adapted from the original article Tessitore et al., 2004108 with the permission of Elsevier
