Fig. 6. Postnatal features of the mutant and control mice. (A) Pictures of the
animals on P21 on an inclined surface, showing the strong postural defect of
mutants (Ht-PA-Cre; ß1fl/ß1),
particularly of the hindquarters (arrow) with respect to controls (Ht-PA-Cre;
ß1fl/ß1+). (B) Body weight of the controls
(red bars) and mutants (blue bars) at birth and P21. (C) Survival curve of the
mutant animals. n, number of scored animals.
