title: [Culture of the bovine graafian follicle in a continuous liquid and gas flow system].
abstract: The culture of 3-5 mm calf follicles in a new glass perfusion cell is compared to the organotypic grid culture using the same synthetic medium and a gas mixture of 55% O2 + 40% N2 and 5% CO2 Amino acid consumption is 3 to 39 times higher in the perfusion cell culture and the mitotic rate is also higher. Moreover, the cytological aspect of granulosa and cumulus cells looks similar to that of non-atresic ovarian follicles. Meiosis resumes up to metaphase 1 or metaphase 2. No pyknotic cells are observed.
