Figure Lengend Snippet: (A) mRNA levels of MAP2 , SYN1 , and LEF1 were quantified after 48 h of different Wnt treatments (2 µg/ml) in hMSCs that had been treated with NTs for 1 week. All Wnts promoted MAP2 expression, and Wnt7a induced the highest SYN1 expression. Levels were normalized to those of NTs treatments (set to 1.0). Data are presented as the mean ± SD of one triplicate experiment that was representative of three independent experiments. 1 p <0.05, 1″ p <0.01 (DMEM vs. all groups); 2 p <0.05, 2″ p <0.01 (NTs vs. all groups); 3 p <0.05, 3″ p <0.01 (Wnt1 vs. all groups); 4 p <0.05, 4″ p <0.01 (Wnt3a vs. all groups); 5 p <0.05, 5″ p <0.01 (Wnt5a vs. all groups); 6 p <0.05, 6″ p <0.01 (Wnt7a vs. all groups). (B) mRNA levels of ChAT , DBH , and LEF1 were quantified after 48 h of different Wnt treatments (2 µg/ml) in hMSCs that had been treated with NTs for 1 week. Wnt1 had no effects on ChAT or DBH expressions, but Wnt7a significantly induced both genes. Levels were normalized to those of NTs treatments (set to 1.0). Data are presented as the mean ± SD of one triplicate experiment that was representative of three independent experiments. 1 p <0.05, 1″ p <0.01 (DMEM vs. all groups); 2 p <0.05, 2″ p <0.01 (NTs vs. all groups); 3 p <0.05, 3″ p <0.01 (Wnt1 vs. all groups); 4 p <0.05, 4″ p <0.01 (Wnt3a vs. all groups); 5 p <0.05, 5″ p <0.01 (Wnt5a vs. all groups); 6 p <0.05, 6″ p <0.01 (Wnt7a vs. all groups).

Figure Lengend Snippet: (A) Wnt7a groups were treated with Wnt7a (2 µg/ml) for 2 days, and the NTs groups were treated with NTs for 9 days. After NTs treatment for 1 week, Wnt7a (2 µg/ml) was added to the NTs+Wnt7a groups for 2 days. mRNA levels of LEF1 , SYN1 , BSN , and SYTG were examined in hMSCs, and levels were normalized to those in the NTs control (set to 1.0).

Figure Lengend Snippet: Accompanying NGF, BDNF, and RA, Wnt7a activated the canonical/β-catenin pathway via receptor Frz5 to promote neurogenesis and trigger synaptic marker (SYN1) expression. Furthermore, Wnt7a also triggered differentiations of cholinergic and dopaminergic neurons, but this effect was induced by another non-canonical/JNK pathway through Frz9 receptors. In this study, we showed that Wnt7a utilized two pathways to promote hMSC neurogenesis.
