Oogenesis in Solea senegalensis: Previtellogenic versus vitellogenic ovaries

Transcriptionnal profile changes in ovary during the reproductive cycle of Solea senegalensis: from previtellogenic stage to vitellogenic stage obtained at different times during the annual reproductive cycle. An oligo microarray based on ESTs sequenced from S. senegalensis previously designed (Cerdà et al., 2008, BMC genomics) was used. The two stages of ovary development were directly compared using three individuals for each stage (IR-Pv-1, IR-Pv-2, IR-Pv-3 for previtellogenic individuals and IR-Vt-1, IR-Vt-2, IR-Vt-3 for vitellogenic individuals). For the experiment, the vitellogenic stage was used as the control.
