The analysis yielded seven clusters, resulting in seven different tumor cell subtypes: C0 FXYD5+ TCs, C1 APCDD1+ TCs, C2 MUC2+ TCs, C3 HEPACAM2+ TCs, C4 OTOP2+ TCs, C5 SLC26A3+ TCs, and C6 AVIL+ TCs, and showed the distribution of the various tissue origins and cellular period distribution in the subtypes (Figure 2A). Here, HEPACAM2 is linked to neoplasm.
