Abstract
Purpose: To evaluate the efficiency of recombinant humanleukemia inhibitory factor (LIF) in the prolonged culture ofhuman cryopreserved-thawing embryos.
Methods: After thawing, all embryos were divided into fourgroups: (1) Human tubal fluid (HTF), (2) HTF + LIF, (3)M3TH medium, and (4) M3TH medium plus LIF. Followingprolonged culture, embryo development in each groupwas compared.
Results: In embryo development from about the 2– to 4–cellto 9– to 16–cell stage, there were nonsignificant differencesbetween each group. There was lower morula formation ratein group 1 (6.9%) than those in other groups (23.2%, 19.7%,23.1%). The lower blastocyst formation in group 1 and 3(0%, 0%) than those in group 2 and 4 (11.0%, 12.8%)were noted.
Conclusions: LIF is beneficial for preimplantation embryos.LIF does not influence the early embryo development.LIF-supplemented HTF provided a similar culture environmentfor thawing embryos as LIF-supplemented M3TH medium.
