Among different subgroups, c16 cells (fibroblasts) had higher expression of six genes (EMP1/DAAM2/LOXL4/LIF/CYTH3/FGFR1); c4 (tumor cells) had higher expression of two genes (ATE1/FGFR1); c7 (stroma cells) and c14 (myeloid) had higher expression of one gene (EMP1); and c11 (tumor cells) had higher expression of one gene (ZC3H7B). Here, LIF is linked to neoplasm.
