NTRK1 and Ewing sarcoma: The upregulated genes in hES-MP cells expressing the LMNA::NTRK1 fusion (clone 13 and 1.14) were found to be enriched among the statistically significant pathways involved in neuronal development, neural crest stem cells, Ewing sarcomas and other soft tissue sarcomas (Fig. 2D and Supplementary Table S1).
