A typical study in developmental biology, targeting the expression of several genes (CheHox9-14A, CheHox9-14B and CheHox9-14C) in the hydroid Clytia hemisphaerica at different stages of development (non-fertilised egg, blastula, gastrula, planula and medusa; from left to right). Scale bars: E, J, O: 100 µm; A–D, F–I, K–N: 50 µm.
