Fig 6. Fgf10 expression at an optimal level in the forelimb LPM cannot rescue asymmetric defects of Tbx5lox/lox; Prx1Cre; Prx1-Tbx mutants.

Fig 6

A-B, Ventral views of mutant embryos at E17.5. The left forelimb is severely truncated compared to the right in Tbx5lox/lox;Prx1Cre;Prx1-Tbx mutant (arrow) (A). Tbx5lox/lox;Prx1Cre;Prx1-Tbx;Z/EGFgf10 mutant lacks digit one in the left forelimb (arrow) (B). C-E, Skeletal preparation of Tbx5lox/lox;Prx1Cre;Prx1-Tbx (C), Tbx5lox/lox;Prx1Cre;Prx1-Tbx;Z/EGFgf10 (D) and control (E) forelimbs. Left forelimbs are more severely affected than right in both examples. Absent digit 1 (thumb) (arrow), bifurcated digit (arrowheads).
