Sox2 (neural stem cells marker) and Ki67 (proliferation marker) immunostaining showed that in both the SVZ and hippocampal DG areas, the NSCs pool was decreased post-ZIKV infection (Supplementary Fig. 3J,K, 40% decrease; Supplementary Fig. 3L,M, 35% decrease respectively). This evidence concerns the gene MKI67 and Zika virus infectious disease.
