Having obtained observations of gene expression profiles from the literature, we estimated autoregressive models of mouse preimplantation development and observed interaction among stages. Gene expression profile at the earliest stage is not generally significant, but for observations where profiles at 8-cell embryo and morula stages are relatively great, the effect of unfertilized egg is significantly positive.
Key words: Cellular biology, embryology, gene expression, interaction, linear regression, multivariate analysis, preimplantation development, temporal changes.
