Fig 3.

The expression of ‘stemness’ genes in somatic cells of invertebrates. Five functional gene categories are depicted, each represented by 3–9 specific genes (in grey boxes). Bilaterian phyla are grouped by colour, with pink for Deuterostomia (Chordata and Ambulacraria) and blue (Spiralia) and yellow (Ecsysozoa) for Protostomia. Ticks indicate that expression of stemness genes in ASCs in at least one species for the phylum has been reported. Note that for most metazoan phyla and many gene categories, no data are available. Only taxa for which sufficient information on ASCs is available are included. The red skull and crossbones indicate the absence/loss of the gene(s) in the phylum. RRM, RNA‐recognition motif. Data from model ecdysozoans are excluded (Drosophila, nematodes; see text for details). See Table S2 for the original data on which this figure is based.
