Reducing Neuron Apoptosis in the Pontine Micturition Center by Nerve Root Transfer for Restoration of Micturition Function after Spinal Cord Injury

Figure 6

Pontine neurons of the three treatment groups, visualized by TEM. TEM analysis showed nuclear pyknosis and mitochondrial vacuolization in Groups A and B at 1 month after surgery, as well as pyknotic margination of chromatin, intercellular space enlargement, and apoptotic bodies. The number of apoptotic cells had increased in Group B. The arrows indicate apoptotic bodies. Scale bar: 1 μm.
