Dynamic modeling of the murine oocyte and somatic cell metabolome during follicle development


ABSTRACT: Explore in vivo ovarian follicle transcriptomics from primordial follicles to the antral stage. Ovarian follicles were isolated from CD-1 mice. Entire ovaries were collected at post-natal day 3 and day 4 to collect primordial follicles. Primary follicles (70-90 µm in diameter), two-layered secondary follicles (100-130 µm), multi-layer secondary follicles (150‒180 µm), and pre-antral follicles (200‒300 µm) were mechanically isolated from post-natal day 10, 12, 16, and 18 ovaries, respectively. Antral follicles (400‒600 µm) were mechanically isolated from pregnant mare serum gonadotropin (PMSG)-treated mice ovaries at post-natal day 20. Follicles were then aspirated and combined per ovarian follicle maturation stage (e.g., primary, two-layered secondary). Three different samples were collected from each pooled follicular stage for transcriptomic analysis. RNA was purified and hybridized in MouseRef-8 v2.0 Expression BeadChip Kit (Illumina, San Diego, CA), as previously described (Skory, Bernabe et al., 2013).
