Fig. 7From: SARS-CoV-2 spike protein S1 activates Cx43 hemichannels and disturbs intracellular Ca2+ dynamicsSpike S1 has no effect on cell viability. Averaged data normalized to the control conditions (dashed line) of MTT cell viability by HeLa-parental, HeLa-Cx43GFP, HeLa-Cx43GFP/ACE2mCherry or HeLa-ACE2mCherry treated with 50 pM spike S1Â for 24, 48, 72 or 96Â h. Data were obtained from at least three independent experiments with two repeats eachBack to article page
