early embryonic polarity and for non-neural ectoderm in the chick embryo

SUMMARY
We have investigated in detail the expression patterns of two Gata genes,
cGata2 and cGata3, during early chick development. In addition to confirming
previously described expression of these two genes in developing brain,
kidney and blood islands, this study reveals several important novel expression
domains during very early stages of development. cGata2 is expressed in
the area opaca in pre-primitive streak stages, forming a gradient along
the A-P axis (strongest anteriorly). Both genes are expressed strongly
in the entire non-neural ectoderm from stage 4+, and neither is expressed
in prospective neural plate at any stage. Unlike other previously described
non-neural markers, neither gene is expressed in the dorsal neural tube.
We also describe dynamic expression of cGata2 and cGata3 during eye, ear
and gut development.
