As the diverse tissues advanced in the sequence of omental-ovarian cancer, with minimal involvement from normal tissues in the developmental process, the distinct subtypes evolved and differentiated in the subsequent order: C3 FN1+ TCs, C2 SLC40A1+ TCs, C1 DAPL1+ TCs, C0 TNFRSF18+ TCs, C4 MEIS2+ TCs, and C5 CFAP126+ TCs (Figures 5G,H). This evidence concerns the gene MEIS2 and ovarian carcinoma.
