Comparative analysis of gene expression profiles between four kinds of blastomere at 8-cell stage embryos.

ABSTRACT: The establishment of body axes and specification of early embryonic cells depend on maternally supplied transcripts and/or proteins, several of which are localized at specific regions of fertilized eggs and early embryos. The ascidian is known to exhibit a mosaic mode of development, and this mode is largely dependent on localized maternal factors. Using blastomere isolation, microarray and whole-mount in situ hybridization, the present study of Ciona intestinalis demonstrates that maternal transcripts of a total of 17 genes are localized at the posterior-most region of fertilized eggs and early embryos. Ten of them are newly identified in the present study, while the remaining seven genes have already been characterized in the previous studies. In addition, maternal transcripts of two
