Fig. 3. Activation of Rx1-GR or Pax6-GR protein at stage 12 does not cause cells to contribute to alternate cell fates. Cells descended from the mRNA-injected D1.1.1 blastomere (red) contribute to head tissues in a pattern identical to normal fate maps (cf. Moody, 1987), including diencephalon (d), lateral epidermis (e), retina (r; outlined), and branchial arch mesoderm (ba). These patterns are consistent regardless of which mRNA was injected (βGal, rx1, pax6), and whether hormone (dex) was added to the culture medium. The expression domains of Nkx2.4 in the ventral diencephalon and pax2 in the optic stalk did not change after any of the treatments. Bar = 100 μm.
