SOD1 and amyotrophic lateral sclerosis: Although the known severity of its ALS phenotype, the increase in expression of lymphangiogenic factors at the mRNA and protein levels (Figs 4 and 5), and its ideal size for iDISCO made us select the EDL for analysis of lymphatic capillary density here, we cannot rule out that other muscles in the SOD1-G93A mice show a different response as far as lymphatic network coverage is concerned.
