DNA microarrays of three shRNA control iPS clones (Ctrl 2,3,4) and shECAD iPS clones (shECAD 4,8,9)

E-cadherin upregulation is an early event of reprogramming of fibroblasts to induce pluripotent stem cells (iPS). Knocking down of E-cadherin by shRNA impairs iPS generation, though some colonies with great morphorlogical difference to shRNA control colonies remain. To illustrate the molecular and functional difference between shECAD iPS clones and shRNA control iPS clones, three respective iPS clones (shECAD 4,8,9 and Ctrl 2,3,4) were derived and DNA microarrays were run to analyze the transcriptional profile of these clones.
