- The absence or presence of labeling was indicated by (−) and (+), respectively. The extent of labeling was indicated with the number of (+). Results showed that with the reduced toxicity and extended animal survival, more connected downstream networks were labeled by the Mutant-VSV compared with the WT-VSV
