Fig. 6. MMP2 is expressed in tissues that abut the developing visual system.
Embryos at stages 32 (A) and 35/36 (B) were processed as wholemounts for in
situ hybridization with a digoxigenin-labelled (blue) XMMP2 antisense
riboprobe. Vibratome transverse sections (50 µm) through the embryo at the
level of the diencephalon. Pigmented cells are shown in black. Broken line
represents the ventral diencephalon, with the optic chiasm found at the
midline. The arrowheads point to Xmmp2 mRNA-expressing cells that
neighbour the optic tectum. R, retina; oc, optic chiasm; Tec, tectum; Ve,
ventricle; D, dorsal, V, ventral. Scale bar: 50 µm.
