Figure 2 x-Pax6, x-Lhx9, x-Lhx5, and x-Dll3 expressions are dynamic during Xenopus forebrain
development. Simple and double in situ hybridization photomicrographs of sagittal (a, c, k–m) and
transverse (b, d–j) sections at the indicated stages. (a–f) x-Pax6 expression. Filled arrowheads point to
Pax6-expressing cell masses in the subpallium. In (d), empty arrowheads point to Pax6-expressing
cells in the prospective septum. In (b), dotted lines indicate the x-Pax6 streams of cells. (g–j) Expression
of x-Lhx5 and x-Lhx9, at embryonic (g, h) and larval (i, j) stages. Filled arrowheads in (i) and (j)
point to xLhx5/9-expressing cells in the medial amygdala (i, j). (k–m) Expression of x-Dll3/x-Lhx7 (k),
x-Emx1 (l), and x-Lhx9/7 (m) on sagittal sections. In this and subsequent figures, see Figure 1 for section
levels and orientation and for anatomical abbreviations, and Table 1 for number of animals used
for each experimental procedure. Scale bar ¼ 100 lm (a, f–m) and 50 lm (b–e). |
