Abstract
The aim of this project is to analyse early Xenopus development under microgravity conditions. Classical embryological studies suggested a role for gravity in the establishment of the spatial structure of the amphibian embryo, but these studies were inconclusive, .... (full text)

Experiment procedure
During the Space Shuttle mission IML-1 (recently re-scheduled for January, 1992), we intend to fertilize toad (Xenopus laevis) eggs under microgravity, and fix them for histology and whole-mount analysis at two different programmed times (viz. third cleavage and the ..... (full text)
