Although activin is expressed in the embryonic central nervous system (CNS), its possible functions in the regulation of CNS neuronal differentiation remain largely unknown. We have investigated this question in the retina, a well-characterized CNS structure previously shown to respond to activin in vitro, and to express activin subunits and receptors in vivo. RCAS retroviruses were used to overexpress...
In Xenopus, the dorso-ventral (D/V) axis is thought to be specified by the bone morphogenetic proteins (Bmp) activity arising through interaction with antagonists such as Noggin, Chordin and Follistatin. We report here, through inactivation of noggin1 (nog1) that this gene is not essential by itself to establish the D/V patterning. However, at blastula stage, inactivation of nog1 strongly amplifies...
