Primary culture and immortalization of human fallopian tube secretory epithelial cells.

Primary human fallopian tube secretory epithelial cell (FTSEC) cultures are useful for studying normal fallopian tube epithelial biology, as well as for developing models of fallopian tube disease, such as cancer. Because of the limited ability of primary human FTSECs to proliferate in vitro, it is necessary to immortalize them in order to establish a cell line that is suitable for long-term culture and large-scale in vitro experimentation. This protocol describes the isolation of FTSECs from human fallopian tube tissue, conditions for primary FTSEC culture and techniques for establishing immortal FTSEC lines. The entire process, from primary cell isolation to establishment of an immortal cell line, may take up to 2 months. Once established, immortal FTSECs can typically be maintained for at least 30 passages.
