Effects of xanthoceraside on neurons in hippocampal DG and CA1 of APP/PS1 transgenic mice. a Immunostaining against the NeuN in hippocampal DG and CA1 regions. b Quantitative analysis of neurons in hippocampal DG and CA1 regions. Values are expressed as the mean ± SEM (n = 6). c Western blots showing the protein level of NeuN in the hippocampus. Scale bar = 20 μm. Values are expressed as the mean ± SEM (n = 5–6). ^# p < 0.05, ^## p < 0.01 and ^### p < 0.001 vs. control; *p < 0.05 and **p < 0.01 vs. model
