MusFIG 24: Distal and proximal gonadal sheath cells have different characteristics.

A. Epifluorescent image showing the anterior gonad arm of a lim-7::GFP transgenic adult hermaphrodite, lateral view, left side. Five pairs of sheath cells (numbered 1–5) cover the arm. The LIM-7::GFP signal is strong in sheath-cell pairs 1–3, weak in 4, and absent from 5. The approximate position of sheath-cell borders is indicated by the dotted line. (N) Nucleus; (PG) proximal gonad; (DG) distal gonad. Magnification, 400x. (Strain source: O. Hobert.)
B. Epifluorescent image of an adult (dissected) gonad arm costained with DAPI (blue, cell nuclei) and rhodamine phalloidin (red, actin). Magnification, 400x. (Image source: D. Killian and E.J. Hubbard.)
