LGALS1 and ocular melanoma: G-PEG-Dx2 treated with OM+hPL resulted in a larger intensity of the dark stain with respect to G-PEG-Dx1 treated with OM+hPL (G-PEG-Dx1, OM+hPL vs. G-PEG-Dx2, OM+hPL, p < 0.001) and G-PEG-Dx2 treated with OM+FBS (G-PEG-Dx2, OM+hPL versus G-PEG-Dx2, OM+FBS, p < 0.001) (Figure 5E).
