Histological examination of neural tube sections. A and B: Transverse sections at the hindlimb level show the expansion of the neural tube in a Prkaca^tm1Gsm/Prkaca⁺ Prkacb^tm1Gsm/Prkacb^tm1Gsm or Prkaca^tm1Gsm/Prkaca^tm1Gsm Prkacb^tm1Gsm/Prkacb⁺ embryo (PKA-deficient) (B) compared with the wild-type (WT, A) at E10.5. C and D: Longitudinal sections through the dorsal half of the neural tube reveal the apparent hyperplasia in the mutant neuroepithelium (D) compared with the wild-type (C) at E10.5. Note the appearance of dorsal root ganglia (DRG, arrows) along the mutant neural tube (D). E and F: transverse sections at the lumbar region of wild-type (E) and mutant embryos (F) at E12.5. Note the dramatic expansion and the abnormal neuroepithelium in the mutant neural tube and the regression of DRG (F). DRG in wild-type is shown in E (arrow).
