When we looked at 20 hpi, we observed an increase in the number of Sox10+ cells in lysolecithin-injected larvae (Figure 2D, right panel) (average 32.96, n = 8) as compared with control-injected larvae (Figure 2C, right panel) (average 26.8, n = 5), which we hypothesize is due to OPC proliferation, a phenomena reported in mammalian lysolecithin-induced demyelination models (Nait-Oumesmar et al., 1999; Keough et al., 2015; Sahel et al., 2015). This evidence concerns the gene SOX10 and Peripheral demyelination.
