Figure 9From: The expression of Delta ligands in the sponge Amphimedon queenslandica suggests an ancient role for Notch signaling in metazoan developmentSummary of the expression of AmqDelta genes during Amphimedon queenslandica development. Schematic representation of A. queenslandica development highlighting the dynamic expression of AmqDeltas across multiple cell layers and cell types. Cell types are identified where possible; note that while each gene is represented with a unique territory of expression, coexpression of ligands in the same cell type is likely: for example, AmqDelta1 and AmqDelta4 in the anterior pole cells, spot stage.Back to article page
