Outline of Final Research Achievements

With the aim of realizing gene transfer into human cells with high throughput and high efficiency, we developed an electroporation technique in micro-reaction fields by the employing microfluidic chip technology. By using this technique, we successfully demonstrated the derivation of human induced pluripotent stem cells (iPS cells) reprogrammed from immortalized lymphoblastoid cell lines (LCL cells). In the future, we will develop an innovative mass-production platform for generating iPS cells with higher level of safety and reprogramming efficiency.
