Figure 7. MAP2-positive cells of the hippocampal neurons isolated from wild type, APP knock-out and APP knock-in mice.

(A) Confocal images of double-stained hippocampal neurons from different mice. (B) The numbers of MAP2-positive cells were counted and expressed as a percentage of the number of DAPI-positive cells, and normalized to that of the knock-out mice. The number percentage of MAP2-positive cells of hippocampal neurons from knock-out mice was set to be 100%. *p < 0.05, **p < 0.01.
