Fig. 6. Proliferation of somatic cells is reduced in egg¹⁴⁷³ germaria. Ovaries were labeled with antibodies to phosphorylated H3S10 (phospho-H3), to detect mitotic cells, and Vasa. (A,B) Left panels, phospho-H3 alone; right panels, merged images of phospho-H3 (green) and Vasa (red). (A) Wild-type germarium and budding egg chamber. The arrowhead indicates a group of germ cells in mitosis and the arrow indicates a mitotic somatic cell. (B) egg¹⁴⁷³ germarium. In this example, a single germ cell is undergoing mitosis. (C,D) Histograms showing the number of wild-type and egg¹⁴⁷³ germaria with the indicated number of mitoses in germ or somatic cells. (C) Germ cell mitosis. See text for an explanation of the germ cell categories. (D) Somatic cell mitosis. WT, wild type.
