Spatial expression patterns of ParaHox genes during Patiria miniata development. Panels A, B, C and D show the expression of PmLox gene. Panels E, F, G, H, I correspond to PmCdx expression. Panels J, K, L, M, N provide the expression domains for PmGsx. In panels A, D, F, L, N and J, embryos and larvae are in frontal view; in B, C, G, H, Ivand M, embryos and larvae are in lateral view; E and K are vegetal views of blastula embryos. Developmental stages are indicated in each panel.
