[Electron microscopy of ameboid oocytes in the lizard: Lacerta vivipara J]

Oocytes at diplotene stage showing a very distinct amoeboid morphology have been observed in the germinal bed of young females. The oocytes produce long pseudopodial formations which extend between the somatic cells. This morphology suggests an autonomous progression of the oocytes which seem to migrate by amoeboid activity towards the area of the germinal bed situated near the ovarian cavity. The increase of the number of the follicular cells which join the oocytes might contribute to stop the amoeboid movements.
