Egg chambers were injected into the abdomen of adult Drosophila. When cultured in this manner, even the earliest detectable developmental stage developed into fully mature eggs. Both isolated egg chambers and those still associated with ovarian structures developed equally well. Maturation occurred within host flies of both sexes in the absence of any hormone treatment.
