Classification of hiPSCs and SCs from gene expression data (A) Heat map and hierarchical clustering for all cells and genes. Cell types are indicated by colored bars, and the following abbreviations are used for the sources of the cell types of the human somatic cells (SCs) and induced pluripotent stem cells (hiPSCs): AM, amniotic membrane cell; PAE, placental artery cell; UtE, uterine endometrium cell; MRC, MRC-5 cell. Details are available in additional file 1. (B) Heat map of the correlation coefficient matrix for all of the cells. See also additional file 3.
