Principal-Component Analysis of mRNA Expression of hPSCs, hPSC-Derived Xenografts, hGCT-Derived Cell Lines and Xenografts and Primary Testicular hGCTs

The top 1,924 differentiating mRNAs (SD > 0.75) were used for principal-component analysis. The first three components (explaining 72.7% of the variance) were plotted. The color code for the different models (and specific culture conditions) is shown on the right. The sample type is indicated by a specific symbol (culture, dot; xenograft as square; hGCT as triangle). See also Figure S1.
