Voorbeelden van antrum

• The cultured follicles developed an antrum, demonstrating that the follicles survived.

• Once the follicle has accumulated a few thousand granulosa cells, a fluid-filled cavity becomes apparent in the extracellular space; this is the antrum.

• Effects of varying gonadotrophin dose and timing on antrum formation and ovulation efficiency of mouse follicles in vitro.

• The oocyte is excentric and there is a dark area where the antrum could form.

• This resulted in a mean final diameter of 471 + 7 m with a high proportion (89%) of antrum formation and healthy appearing oocytes.

• Unexpected oocyte growth after follicular antrum formation in four marsupial species.

• The physical barrier properties of healthy growing follicles can be evaluated by measuring the penetration of plasma proteins in the antrum as a function of their concentration in blood.

• Reversal of anionisation, however, restores their capacity to freely enter the antrum once again.
