Figure 2.

a–c, Serial confocal maximum projections of a YFP-expressing dentate granule cell exhibiting conversion of a dendritic branch to a primary dendrite. Images taken over 6 d exhibit the translocation of a dendritic branch (blue arrow) to the cell body at 9 DIV, thus converting it to a primary dendrite. Blue circles denote the length of the primary dendritic segment. Scale bar, 50 μm. d–i, Deconvolved confocal images showing the conversion of a dendritic branch (blue arrow) to a primary dendrite at 8 DIV. Following hypertrophy of the cell body on 12 DIV, the previous dendritic branch—now primary dendrite—proceeds to move back into position as a dendritic branch, this time, however, on a different dendrite. Scale bar, 25 μm.
