S100ß and NDRG2 immunoreactivity in the rat brain. a (merged) Neocortex layer III; most labeled cells (asterisk) are immunoreactive for both antigens (yellow). b (red channel) Corpus callosum; NDRG2 expression in some cells is relatively weak (arrow). c Green channel (corresponding to b): The cell that is also indicated in (b) (arrow) shows a pronounced S100ß expression; arrowhead denotes S100ß immunoreactive fiber. d (merged) The cell that is also indicated in (b and c) shows strong S100ß but weak NDRG2 immunoreactivity; arrowhead denotes S100ß immunoreactive fiber that does not contain NDRG2
