Evolutionary modification of specification for the endomesoderm in the direct developing echinoid Peronella japonica: loss of the endomesoderm-inducing signal originating from micromeres
{{output}}
We investigated the inductive signals originating from the vegetal blastomeres of embryos of the sand dollar Peronella japonica, which is the only direct developing echinoid species that forms micromeres. To investigate the inductive signals, three different k... ...
