Although mvE cells were not associated with genomic status (microsatellite stable (MSS), microsatellite instability (MSI)-low, and MSI-high) (Figure S4) and mutation of BRAF, KRAS, and NRAS genes (Figure S5), mvE cells in mucinous adenocarcinoma were significantly higher than in adenocarcinoma (Figure S6). Here, BRAF is linked to mucinous adenocarcinoma.
