Update: The poster is now available at Nature Precedings.
Still acquiring histological images for my SfN poster. My recurring problem is that I end up taking pictures of things because they’re pretty and not because they have anything to do with the task at hand. Today’s case in point:
Well, this does relate to my SfN poster a little bit. Red shows cell nuclei, most of which are dentate gyrus granule neurons. And white is GFAP immunostaining, which largely labels astrocytes but in this part of the brain also labels radial glia, the stem cells (or to be less controversial, “precursor” cells) of the hippocampus. Radial glia can be identified by the long process (almost like a dendrite) that they extend through the granule cell layer. There are a few in the above picture. Read the rest of this entry »
