Interestingly, FC2 displayed the highest correlation with epithelial cells (Figure S4D) and showed specific expression of tumor epithelial markers KRT8, KRT10, and KRT18 (Figure S4E), as well as the EMT markers SNAI1 and SNAI2 (Figure S4E), suggesting that FC2 may have the tumor‐like aggressive potential. Here, SNAI1 is linked to neoplasm.
