atp1a1.L laevis NF stage 22 to NF stage 35 and 36 hypochord

  FIG. 9. The expression of a1 subunit protein after closure of the neural tube. (A) Stage 22/23. Note intense stain of notochord, floor plate (FP), and apical surfaces of neural tube cells (NT). som, somites. (B) Enlargement of A to show the region just above the notochord to further illustrate floor plate (FP) and neurocoel lining stain. NT, neural tube. (C) Ventral region of same section to show pattern of a1 subunit protein expression in the expanding archenteron (arch). The ventral side of the notochord is just visible. The somites (som) continue to show little expression. (D) Stage 36. The dorsal notochord and ventral region of the neural tube (NT). Note marked expression along the cell surfaces lining the neurocoel, particularly in the floor plate. (A, C) Bar, 100 mm; (B, D) Bar, 25 mm.
