Abstract:

BACKGROUND: The successful establishment of human embryonic stem cell lines in vitro is of great significance to human embryonic development mechanism and developmental biology, cell and tissue transplantation in the treatment of certain diseases.

OBJECTIVE: To summarize the progress of in vitro culture of embryos and establishment of embryonic stem cell lines, to explore the influential factors for in vitro culture of embryos, and the methods of culturing human discarded embryos, isolating inner cell mass and establishing embryonic stem cell lines, as well as the establishing conditions for embryonic stem cell lines.
METHODS: With the key words of “embryo, embryonic stem cells, coculture, sequential culture”, the first author searched CNKI and SCI databases for literatures concerning in vitro culture and transplantation of embryos and establishment of embryonic stem cell lines published from 2000 to 2014. Systematic evaluation was conducted. Finally, 58 literatures were retained for result analysis. 
RESULTS AND CONCLUSION: The culturing condition for embryos in vitro is the key factor affecting embryo transfer outcomes, including culture medium component and culture system. In previous studies, the component and application of culture medium have changed greatly, and the culture system has altered from single culture to coculture and sequential culture. Ethical issues and embryonic origin restrictions restrict the establishment of human embryonic stem cell lines. Clinically discarded low-quality embryos can be used as one of the material sources to establish human embryonic stem cell lines, which can effectively lessen the problem of embryo shortage during the establishment of human embryonic stem cell lines and reduce ethical disputes.
