Abstract
Mammalian oviductal epithelial cells have been known to improve in vitro fertilization and embryonic development. Recently, co-cultured human embryos with the epithelial cells in human genital tract has been reported to improve the pregnancy rate. The purpose of the study was to investigate the effects of the epithelial cells of human genital tract on the development of mouse early embryos and human fertilized oocytes. The epithelial cells of human genital tract were collected from the fallopian tubes which were obtained during hysterectomy in fertile women and from the endometrium during endometrium biopsy. Collected human ampullary cells(HACs) and endometrial cells(HECs) were cultured for 10 days to establish primary monolayer. Second passaged HACs and HECs were obtained by trypsinization were cryopreserved in PBS with 1.5 M DMSO for later use. To investigate the effect when co-cultured with HACs and HECs, we tried to apply strict quality control on mouse embryo, from two cell to blastocyst prior to human trial. The results of quality control were as follows; In Group I (Ham's F10 with 10% FCS), Group IT (co-cultured with HACs) and Group ill (co-cultured with HECs), developmental rates to blastocyst were 63.3%(253/400), 76.0%(304/ 400),74.0%(296/400), respectively. Hatching rates were 36.8%(147/400), 41.80/0(167/400), 38.0%(152/400), respectively(p<0.05). To perform the human IVF, cryopreserved HACs were thawed at 37
