Figure 1

Light micrographs of ovaries (A-B) and follicles (C-D) of T. molitor . Saline controls (A, C), treated (B, D). Ovary of control female shows large terminal follicle with oocytes full of yolk (A), ovary of treated female has small atretic follicles (B). Terminal follicle of control shows intracellular spaces between follicle cells (patency) stained with 1% Evans blue (C), terminal follicle of treated females shows no Evans blue stain indicating lack of patency (D). Females were injected with saline (control) or 10 nmole Neb-colloostatin (treated) on day 3 and assayed on day 4. Scale bars: 1 mm (A, B) and 0.5 mm (C, D).
