E.F. Bondan, M.A. Lallo, A.H. Trigueiro, C.P. Ribeiro, I.L. Sinhorini and D.L. Graça (2006). Delayed Schwann cell and oligodendrocyte remyelination after ethidium bromide injection in the brainstem of Wistar rats submitted to streptozotocin diabetogenic treatment. Brazilian Journal of Medical and Bilogical Research, 39: 637-646.  

Figure 2. Group I. A, 7 days after ethidium bromide injection. Demyelinated axons (d) in an area containing large amounts of myelin-derived membranes (asterisks), phagocytic cells (M) and even a degenerating axon (arrow). Bar = 1 µm. B, 15 days after ethidium bromide injection. A Schwann cell (S) surrounds a naked axon near some oligodendrocyte-remyelinated axons (r). Bar = 5 µm. C, 15 days after ethidium bromide injection. An oligodendrocyte (O) is seen next to thinly remyelinated axons (r). Bar = 1 µm. D, 21 days after ethidium bromide injection. Axons present initial deposition of few myelin lamellae (arrowheads) of oligodendroglial origin. Bar = 0.5 µm.
