Although there was no significant statistical difference (nsp > 0.05), the amount of pro-inflammatory factors IFN-γ (Fig. 5A, 4.86 ± 3.49 pg/mL), IL-1α (Fig. 5B, 1.61 ± 1.76 pg/mL), and IL-2 (Fig. 5D, 810.12 ± 134.60 pg/mL) in PD + MenSCs group was less than those in PD + PBS group (7.55 ± 2.39 pg/mL for IFN-γ, 6.05 ± 2.03 pg/mL for IL-1α, 1095.92 ± 245.76 pg/mL for IL-2). This evidence concerns the gene IL1A and Parkinson disease.
