Olfactomedin transcripts are differentially expressed in non-pregnant Fallopian tube and Fallopian tube from women with ectopic pregnancy. (A) The expression of Olfm (Olfm-1, -2, -3 and -4) transcripts in different regions of non-pregnant Fallopian tube in the follicular (n=14) and luteal (n=15) phases of the menstrual cycle was quantified by real-time PCR. The expression of each Olfm transcript at the infundibulum region at the follicular phase of the cycle was arbitrary set to a value of 1. Inf: Infundibulum, Amp: Ampulla, Isth: Isthmus, * p<0.05, **p<0.01 and ***p<0.005. (B) Olfm-1 protein is differentially expressed in the ampullary region of non-pregnant Fallopian tube at the luteal phase and Fallopian tube from women with ectopic pregnancy. The negative control section was included by using pre-absorbed antibody with blocking peptide (left panel). The arrows show the localization of Olfm-1 protein in the luminal epithelial cells of the ampullary region (x400). The right panel illustrates the Olfm-1 and cytokeratin staining in the intact epithelium of the same TEP sample. FT: Fallopian tube, Em: Embryonictissues. Scale bar = 100 μm.
