- Abstract
- We demonstrated that two mRNAs that are
synthesized during the vitellogenic period of oogenesis and that
code for cell surface proteins are asymmetrically distributed in
the unfertilized egg of Paracentrotus lividus. At fertilization,
these RNAs rapidly localize in the cortical zone at the animal
pole of the egg. They are then detected in the mesomeres and
the macromeres, but not in the micromeres, and thereafter are
found in the ectoderm but not in the vegetal plate, mesenchyme
cells, or early intestine. They disappear in late gastrula. The
proteins synthesized by these mRNAs show the same territorial
location during the period examined here, which included the
unfertilized egg and the 16-blastomere stage. These conclusions
were reached on the basis of in situ hybridization and immuntaning
experiments, as well as Northern and Western blot
analyses of isolated blastomeres. The possible sinificance of
this asymmetric distribution of these two mRNAs and proteins
in the establishment of the animal/vegetal axis is discussed. (literal)
