Folic acid + MSC-derived soluble factor effect. Folic acid (2.5–100 μM) was added to the bottom chamber in the coculture medium + 50 μL mesenchymal stem cell culture medium at each concentration; cell proliferation was measured in real time for 48 h at 7 concentrations. The trend change between repeating measurements was analyzed using Mauchly’s sphericity test (P < 0.05).
