activinB mRNA Distribution during Early Sea Urchin Development at the Stages Indicated During early blastula and cleavage stages of development (a–c), low levels of activinB transcripts accumulate throughout the embryo. At the mesenchyme blastula stage (d), activinB mRNA is expressed in most of the embryo except one side of the ectoderm. At the late gastrula stage (e), activinB mRNA expression is detected in the gut and oral ectoderm and in the gut in prism (f) stage embryos.
