Fig. 3From: Large-scale gene expression study in the ophiuroid Amphiura filiformis provides insights into evolution of gene regulatory networksIn A. filiformis hesC is co-expressed with its immediate downstream genes. a Single WMISH for blastula and mesenchyme blastula stage embryos. b Double fluorescent WMISH on blastula stage embryos. Afi-hesC expression is restricted to a ring of cells in the vegetal half and co-expressed with the endomesodermal marker Afi-foxA. Afi-ets1/2, Afi-tbr, and Afi-delta are co-expressed with Afi-hesC in one cell layer (yellow area) at the vegetal plate of the embryo at blastula stage and completely co-expressed at mesenchyme blastula stage.
