LGALS1 and neoplasm: Similarly, alignment of highly expressed genes from EGFR+ PDGFRA+ and EGFR+GAL1+ revealed that EGFR+PDGFRA+ cells display profiles similar to those from cells of cellular tumor, leading edge and infiltrating tumor, whereas EGFR+GAL1+ cells express genes similar to perinecrotic zones, pseudopalisading regions and hyperplastic blood vessels (Extended Data Fig. 3g).
