Tubal Origin of “Ovarian” Low-Grade Serous Carcinoma: A Gene Expression Profile Study

Figure 1

Identification of differentially expressed genes in examined tissue samples. Dendrograms produced by unsupervised hierarchical clustering according to differentially expressed genes, revealing the overall similarity of FTE and OEI and serous tumor samples. FTE samples are more closely resembling LGSCs compared with OSE samples. FTE, fallopian tube epithelia; OEI, ovarian epithelial inclusions; SC, serous cystadenoma; SBT, serous borderline tumor; LGSC, low-grade serous carcinoma; OSE, ovarian surface epithelia.
