LiCl facilitated the generation of dopaminergic neurons from NSCs. Statistical analysis showed that co-application of LiCl as well as laminin, heparin and bFGF (LHF) (a), co-application of LiCl and LH, LF or HF (b) could increase the ratio of TH⁺ cells differentiated from NSCs, while co-application with laminin or heparin or bFGF (c) did not significantly enhance differentiation to dopaminergic neurons. Statistical difference was determined by unpaired Student’s t tests. *p < 0.05; **p < 0.01
