stage S9 oocyte [FBbt_00005269]

Oocyte during stage 9 of oogenesis. Its nucleus is located adjacent to the dorsal follicle cell-nurse cell border and the karyosome expands into individual chromosomes for a short period of RNA synthesis (Mahowald and Kambysellis, 1980). The oocyte has grown to around 1/3 of the size of the egg chamber (Mahowald and Kambysellis, 1980). Follicle cells begin to secrete vitelline membrane components, which accumulate around the oocyte as vitelline bodies (Spradling, 1993).
