ACE2 and CCN1 are co-expressed in hiPSC-NS/PCs. and b Immunostaining images of ACE2 (green) and neural stem/progenitor cell (NS/PC) marker Nestin (red) in hiPSC-NS/PCs. b is a high-power field. ACE2 (green) and Nestin (red) are co-expressed. Scale bars represent 50 μm in a and 20 μm in b. c and d Immunostaining images of CCN1 (green) and NS/PC marker Nestin (red) in hiPSC-NS/PCs. CCN1 (green) and Nestin (red) are co-expressed. d is a high-power field. Scale bars represent 50 μm in c, and 20 μm in d. e and f Immunostaining images of CCN1 (green) and ACE2 (red) in hiPSC-NS/PCs. CCN1 (green) and ACE2 (red) are co-expressed. f is a high-power field. Scale bars represent 50 μm in e, and 20 μm in f. Nuclei were counterstained with Hoechst (blue)
