Description
Abstract
y. Oligodendrocytes are the myelinating cells of
the central nervous system. Since many studies of
demyelinating diseases focus their research on this cell
type, there is growing interest for obtaining reliable
markers that can specifically recognize oligodendroglia.
Established markers are the myelin-associated neurite
outgrowth inhibitor (NogoA), the transcription factor
Olig2, and the antibody CC-1, the latter being directed
against the protein adenomatous polyposis coli (APC).
Unfortunately, it has been discussed whether APC and
Olig2 could recognize astrocytes under pathological
conditions as well. Hence, we performed immunohistochemical studies using the oligodendroglial markers
NogoA, APC, and Olig2 in a murine model of cuprizone
induced demyelination. We have found that APC colocalizes with NogoA and does not co-localize with the
astrocytic marker GFAP. Olig2 shows co-localization
with APC but there is also a small population of
Olig2/GFAP double positive cells. Some Olig2/GFAP
double positive cells are found in the corpus callosum in
a narrow time window in which oligodendrocyte
precursor cells proliferate in this model. In other brain
regions including the cerebral cortex and hippocampus
and in all regions in untreated control mice double
positive Olig2/GFAP cells do not occur. In conclusion,
our results underline that APC and NogoA are reliable
markers for detection of mature oligodendrocytes. Olig2
is a suitable marker to stain cells of oligodendroglial
origin but could be combined with GFAP to exclude the
GFAP positive population of cells from the
quantification of oligodendroglia.
