(E) Schematic representation of the statistical analysis estimating the probability of co-expression of the nine TRs per cell within the early-iPSCs colonies. Each row consists of 9 tiles representing a single cell and each column shows the expression status of each of the nine TRs (shown with different color) in 282 cells (right side legend). The co-expression of gradually increasing numbers of TRs is grouped from the bottom to the top of the figure. The left part has been generated by estimating the percentages of expression of any single TR per cell as derived from single gene expression in single cells, while the right part depicts the co-expression of combinations of the nine TRs based on double and triple single-cell experiments.
