| Outline of Final Research Achievements |
Human pluripotent stem cells (hPSCs), i.e. human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs), are able to self-renew and differentiate into multiple cell types. Thus, numerous attempts have been made to utilize hPSCs in regenerative medicine/cell therapy. However hPSCs have tumorigenic potential. Therefore, residual undifferentiated hPSCs or contamination of the transformed cells in products that would eventually proliferate and form a teratoma is one of the most obvious safety issues to develop cell therapy hPSC-derived products. In the present study, we identified a new immortalized RPE cell marker and developed new qRT-PCR method to detect contamination of human RPE cells with immortalized RPE cells. This qRT-PCR assay can detect as few as 3% of immortalized RPE cells in normal RPE cells. This in vitro qRT-PCR method is expected to contribute to process validation and quality control of cell therapy products derived from hPSCs.
