Figure 1: Distribution of expression patterns and transcriptome complexity.
From: Human chromosome 21 gene expression atlas in the mouse

a, Each slice corresponds to the percentage of genes belonging to the four categories of expression pattern observed by ISH at E9.5 (whole mount), E10.5 (whole mount) and E14.5 (sections). b, Each slice represents the percentage of genes expressed in 0, 1, 2–3, 4–9 and 10–12 adult tissues by RT–PCR. c, Percentage of the analysed 161 human chromosome 21 murine orthologues identified in each murine adult tissue.
