Tumor cells in mETMR-FBO (NES+, some expressing nuclear β-Catenin) and hETMR-FBO (NES+; LIN28a+) recapitulated the major histopathological features of primary ETMR, including a similar neuronal differentiation profile (Fig. 4D; Supplementary Fig. S13A, B). This evidence concerns the gene LIN28A and neoplasm.
