ABSTRACT

BACKGROUND:

Induced pluripotent stem cels have been a hotspot in regenerative medicine research since it was discovered. The clinical application of induced pluripotent stem cels is excessively focused on, but the safety issue is almost ignored.

OBJECTIVE:

By summarizing the application of induced pluripotent stem cels in animal experiments to analyze the safety problems of induced pluripotent stem cels and their possible reasons in order to lay a foundation for further study and clinical application of induced pluripotent stem cels.

METHODS:

PubMed database was retrieved by the first author for articles related to the safety of induced pluripotent stem cels published from 2006 to 2014 using the keywords of “induced pluripotent stem cels, safety, immune, immunogenicity, tumorigenicity, cancer, epigenomic, transplantation, generation, reprogramming,genomic, mutation” in English. Related ful texts were got from Cel Press and Nature Databases. Finaly, 28 articles were chosen in result analysis. RESULTS AND

CONCLUSION:

Safety problems of induced pluripotent stem cels are attracting more and more attentions. Immunogenicity, potential tumorigenicity and epigenetic variation are major risks for the clinical applications of induced pluripotent stem cels. Safety issues of induced pluripotent stem cels mainly come from the reprogramming process. The “integrating genetic manipulation” may lead to a greater risk of tumorigenicity than non-integrating operations. Epigenetic variations emerge in the reprogramming, which are mostly relative to “epigenetic memory” of reprogrammed cels.
