Three regions of the 32-cell embryo of Xenopus laevis essential for formation of a complete tadpole
Article Abstract:
The formation of a complete tadpole needs at the minimum cells in three regions of the 32-cell embryo: the dorsovegetal, ventrovegetal and animal regions. One dorsovegetal, two ventrovegetal and eight animal cells make up the minimal cell requirement. Forty percent of defect embryos with the minimal set of cells developed into tadpoles that were approximately a quarter of normal size but normal in other respects. Also discussed is the mechanism of pattern formation at the blastula stage, taking into account the 'three signal model' of mesoderm formation.

Inductive events in the patterning of the Xenopus laevis hatching and cement glands, two cell types which delimit head boundaries
Article Abstract:
Researchers analyzed the induction of the hatching and cement glands that constitute the major boundaries in the head in Xenopus to determine the causes of the ectodermal formation. Several different tissues were covered with ectodermal cells as explant cultures to study inducing functions. The induction of hatching and cement glands may be concerned with distinct passages because of the presence of retinoic acid and lithium-treated embryos.
