KCND2 and Alzheimer disease: Characterization of differentiated hMSCs for their functionality was performed at gene level by studying the relative fold change in the mRNA expression level of Kv4.2, SCN5A and DAT. DAT showed highest upregulation in AD-MSCs (4.16 ± 0.32 change folds), followed by that in BM-MSCs (2.66 ± 0.31 change folds) and DP-MSCs (2.56 ± 0.46 change folds), with no significant difference.
