Moreover, we evaluated the expression of Ron isoforms in 3 of our newly developed HG-SOC PDX tumor models, which have also been immunohistochemically characterized for the expression of commonly used markers for HG-SOC subtype such as pan-cytokeratin (CK), PAX8 and WT1 (Supplementary Fig. 3). The gene discussed is WT1; the disease is neoplasm.
