    Gap junctions between the oocyte and companion follicle cells in the mammalian ovary

    por Odor, D. Louise
    Publicado 1960
    “…The relationship of the oocyte to the surrounding granulosa cells was found to change from one of a simple apposition of the plasma membranes to a complex interdigitation of microvilli from the ovular surface and processes from the granulosa cells extending into the matrix of the zona pellucida. This complex interrelation is maintained until the formation of the first polar body is initiated. …”
