Abstract:

BACKGROUND: As embryonic stem cells, induced pluripotent stem cells are able to self-renew indefinitely and differentiate into all types of somatic cells. Induced pluripotent stem cells are not only valuable for cell replacement therapy, but also useful for disease modeling in vitro, facilitating studies of mechanisms underlying disease development, drug screening, and development of new therapeutic strategy.
OBJECTIVE: To comprehensively analyze the method for induced pluripotent stem cells.
METHODS: An online search of PubMed database and China National Knowledge Infrastructure was undertaken to identify articles about induced pluripotent stem cells published from January 2006 to December 2011. The keywords were “induced pluripotent stem cells”. 330 literatures were collected, and those old or repetitive literatures were excluded. Thus, 31 literatures were included.
RESULTS AND CONCLUSION: Articles explained the following aspects: gene transfer into induced pluripotent stem cells, protein transfer into induced pluripotent stem cells, micromolecule transfer into induced pluripotent stem cells, properties and difference of induced pluripotent stem cell line, to elevate the transformation efficiency of induced pluripotent stem cells, application of induced pluripotent stem cells in the treatment of animal disease models. Studies have found that somatic cells with suitable matching transcription factor are potential practical initiation point of producing induced pluripotent stem cells. Gene transfer into induced pluripotent stem cells still has unsolved problems, but protein transfer into induced pluripotent stem cells cannot affect hereditary substance of cells. The combination of induction technique of induced pluripotent stem cells and transgenic animal technique can perform directed variation and breeding, elevate animal’s heredity, accelerate hereditary variation of animal population. Induced pluripotent stem cells not only have essential values in substitution therapy, but also can be used in the establishment of in vitro disease models, which contributes to the study of disease mechanisms, drug monitoring and determination of new therapeutics.
