Expression profiles of specific orthologous genes in Xenopus , mouse, and cow. The microarray expression profiles of specific gene in the somatic cells surrounding the oocyte during competence acquisition are shown. The mean expression is shown for the following: developmentally incompetent or poorly competent prophase I oocytes (NC1), developmentally competent prophase I oocytes (C1), and developmentally competent metaphase II oocytes (C2).
