Figure 2. FGF signaling acts in multiple somatic cell types within the developing gonad at the larval and pupal stages.
(A) Schematic showing ovarian morphogenesis at three stages: mid-larval third instar (ML3), early pupae, and middle pupae. In this an all other panels/figures, lateral views of the larval/pupal ovary are shown with anterior up and posterior down.
(B-D) Immunostainings of ovaries obtained from transgenic line htl-mcherry using anti-RFP antibody (white). Three different stages are shown: ML3 (B), early pupae (C), and middle pupae (D). Arrowhead in (B) marks migrating swarm cells at ML3.
(E-G) Immunostainings of wildtype ovaries using anti-Dof (green) and anti-α-Spectrin (red) antibodies. Three different stages are shown: ML3 (E), early pupae (F), and middle pupae (G).
