Auersperg [17] studied the stem cell profile of oviductal fimbriae with 5 stem cell markers (NANOG, SFRP1, LHX9, ALDH1A1, and ALDH1A2); the author found that the fimbriae express the stem cell markers (mainly ALDH1A1, also known as ALDH1) and concluded that the fallopian tube may be pluripotent with the capacity to generate cancer stem cells. Here, SFRP1 is linked to cancer.
