Fig. 2. Loss of expression of parvalbumin in
Runx3-/- DRGs during
development. (A-F) Photomicrographs indicate parvalbumin (PV)
immunoreactivity (brown) at E14.5 (A,D), E18.5 (B,E) and P0 (C,F) in wild-type
(A-C) and Runx3-/- (D-F) DRGs at the level of Th12.
(G) Quantification of PV+ DRG neurons from E14.5 to P0. The
number of PV+ neurons in wild-type (white squares) and
Runx3-/- (black squares) mice are shown, and virtually no
neurons express PV in Runx3-/- DRGs through these
developmental stages. SC, spinal cord. Data are shown as mean±s.e.m.;
*P<0.001. Scale bar: 100 µm.
