چکیده

Background: Embryonic stem cells (ESc) are pluripotent cells which have been used as a model to study the mechanism that control the embryogenesis and early mammalian development in vitro.The aim of this study was to isolate and produce embryonic stem cells from late blastocyst stage embryos in mice. Materials and Methods: Blastocyst stage embryos from pregnant NMRI mice were obtained and cultured for 24 h in DMEM medium. 4-6 days after hatching, the inner cell masses (ICM) formedcolonies which were then collected mechanically and trypsinized. Several subcultures were preparedin the medium supplemented with 0.1 mM 2 Mercaptoethanol, 1000 U/ml Leukemia Inhibitory Factor (LIF) and 10% Fetal Bovine Serum (FBS). The (ESc) were recognized by alkaline phosphates histochemistry using azo-coupling method.Results: The results demonstrated that a highly pluripotent stem cell line was derived from theblastocyst stage embryos of NMRI mice; however, the rate of colonies was as low as 10%.Conclusion: The LIF is effective to culture and maintain the isolated ICM colonies in undifferentiated condition in the absence of feeder layer

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
