These results indicated that all cell types in cervical cancer may be the source of CD99, but only C0 TMPRS2+ Tumor EPCs subgroup, C1 ANKRD36C+ Tumor EPCs subgroup, C2 HK2+ Tumor EPCs subgroup and C3 PLP2+ Tumor EPCs subgroup had different targeting intensities (line width between cells) for CD99 (Figure 6E). Here, CD99 is linked to cervical cancer.
