FIGURE 4.

Unique groups representing the significant transcript sub-cellular alterations between the different oocyte sizes of the Xenopus laevis. Four groups of localization profiles were observable, early vegetal, late vegetal, late animal and polar. The following subgroups were observed: same profile - similar profile in early and late stages; predefined - profile already established in the early stages; homogeneous very small/small - profile is ubiquitous in the small/very small stage; homogeneous vs., s - profile is ubiquitous in both the small and very small stage. The sections correspond to the regions of the oocyte that were cryosectioned, whereby sections A - extremely animal, B - animal, C - central, D - vegetal, E - extremely vegetal.
