Fig. 5. Reduced brain weight and size of Pkb
mutant mice. (A)
Weight of freshly dissected brains of male Pkb
+/+
(white bars) and Pkb
-/- (black bars) mice were
measured at different points in time (n=5-8 animals per genotype).
*P<0.05. Error bars represent s.d. NB, newborn. (B)
Cranial, (C) caudal and (D) lateral views of brains from adult
Pkb
wild-type (left side) and knockout (right side) mice. Co,
cortex; CE, cerebellum; OB, olfactory bulb; BS, brainstem; HY, hypothalamus.
(E-J) Representative sections from T2- weighted 3D MRI
data sets acquired in vivo from the brains of
Pkb
+/+ (E,G,I) and
Pkb
-/- mice (F,H,J) from
Pkb
+/- matings in sagittal (E,F), horizontal (G,H)
and coronal (I,J) orientation. CC, corpus callosum; AC, anterior commissure;
PC, posterior commissure. Scale bar: 1 mm.
