title: [Role of follicular cells in the inertia period of oocyte maturation in the common frog].
abstract: Out of the breeding season the in vitro maturation of Rana temporaria oocytes in the state of maturation inertia or close to it depends on the follicular cells. In 28 females the presence of follicular cells stimulated oocyte maturation, in 12 females inhibited it. Dibutyrylcyclic AMP (5 X 10(-5) M) increased the percentage of maturation of follicle--enclosed oocytes close to the state of maturation inertia; estrone (4 X 10(-5)-10(-7) M and more) decreased the percentage of maturation of oocytes in the state of inertia, both with and without follicular envelopes.
