Based on a previous finding that fusion of a somatic cell with an embryonic stem (ES) cell reprogrammed the somatic cell, genes for reprogramming transcription factors were selected and induced pluripotent stem (iPS) cell technology was developed. The cell fusion itself produced a tetraploid cell. To avoid nuclear fusion, a method for cytoplasmic fusion using a microtunnel device was developed. However, the ES cell was too small for cell pairing at the device. Therefore, in the present study, ES cell enlargement was carried out with the colchicine derivative demecolcine (DC). DC induced enlargement of ES cells without loss of their stemness. When an enlarged ES cell was paired with a somatic cell in the microtunnel device, cytoplasmic fusion was observed. The present method may be useful for further development of reprogramming techniques for iPS cell preparation without gene transfection.
