Figure 6.

Genes for proteins localized to the extracellular space and for transcriptional regulators clustered according to expression profiles in MAPC/ESC/NS comparison. (a, b) Genes expressed at levels at least twofold higher in both MAPCs and ESCs than in NS (k-means clusters 2 and 4). (c, d) Genes expressed in MAPCs at levels at least twofold higher than in both ESCs and NS (k-means cluster 3). The yellow bars indicate genes whose products are localized to the extracellular space; the blue bars indicate genes for transcriptional regulators. Red and green indicate higher and lower levels of expression, respectively.
