Abstract:

BACKGROUND: Due to pluripotent characteristics, induced pluripotent stem cells can be induced to differentiate into the specific cells, including nerve cells and hematopoietic cells.
OBJECTIVE: To establish the induced pluripotent stem cells generated from villus cells during prenatal diagnosis.
METHODS: The prenatal diagnosis villus cells were induced by retroviral vectors encoding hOct4, hSox2, hKlf4 and hc-Myc. The pluripotency, differentiation ability and karyotype of the induced pluripotent stem cells were detected.
RESULTS AND CONCLUSION: The induced pluripotent stem cells maintained the self-renewal ability with high pluripotent marker gene and protein expression and had in vivo and in vitro differentiation potential. The induced pluripotent stem cells could maintain normal karyotype in vitro after long-term culture. The induced pluripotent stem cells obtained from the prenatal diagnosis villus cells provide an ideal source for autologous cell-replacement therapy in the later life of the fetus, and can be used as a perfect model for the research of mechanism underlying prenatally diagnosed diseases.
