Both PitX3 and ngn2 were maximally upregulated in AD-MSCs (5.4 ± 0.19 folds change in PitX3 and 2.93 ± 0.21 folds change in ngn2) and DP-MSCs (5.58 ± 0.65 folds change in PitX3 and 2.970 ± 0.1984 folds change in ngn2), with no significant difference, except in BM-MSCs (2.66 ± 0.42 folds change in PitX3 and 1.63 ± 0.27 folds change in ngn2), showing significant difference. This evidence concerns the gene PITX3 and Alzheimer disease.
