Generation of intestinal epithelial cell line from induced pluripotent stem cell and establishment of colorectal cancer stem cell model

Induced pluripotent stem cell is the ideal stem cell and it is not necessary to use embryonic stem cell. In this study, we aimed to establish normal intestinal epithelium cell line by progenitor of endoderm induced from mouse iPS cells in the first step and differentiated by gene transfer of intestine-specific homeobox transcription factor CDX2. In the next step, we aim to generate iPS-induced colorectal cancer stem cell line with transformation using gene transfer of colorectal cancer-related gene. By analyzing the these cell lines, we aimed to identify novel target of the colorectal cancer-related genes with the microarray analysis.
