Nurse cell death and transfer of material blocked in dcp-1-deficient mutants. (A, B) Control egg chambers, at stage 10A and 14, showing the death of the nurse cells and the transfer of their cytoplasmic contents (here visualized by the staining of b-galactosidase) into the oocyte. (C, D) Similar stages of a dcp-1-deficient mutant showing neither cell death nor the transfer of material into the oocyte. (From McCall and Steller, 1998.
