Caption Gt(ROSA)26Sortm1(Tbx1/GFP)Bem (Tbx1-GFP) can patially rescue heart phenotypes in Tbx1tm6(cre)Bld/Tbx1tm1Bld (Tbx1Cre/-) mice. Histological transverse sections through the heart at E14.5. (A) Tbx1tm6(cre)Bld/Tbx1tm6(cre)Bld mice are functionally null and have persistent truncus arteriosus (PTA) and ventricular septal defects (VSD). Tbx1Cre/+;Tbx1-GFPflox/+ mutants are viable with normal heart histology. (B) Tbx1tm6(cre)Bld/Tbx1tm1Bld Gt(ROSA)26Sortm1(Tbx1/GFP)Bem/Gt(ROSA)26Sor+ (Tbx1Cre/-;Tbx1-GFPflox/+) mutants exhibit complete rescue of outflow tract septation although half of the embryos have double outlet right ventricle (DORV). (C) Tbx1tm6(cre)Bld/Tbx1tm1Bld Gt(ROSA)26Sortm1(Tbx1/GFP)Bem/Gt(ROSA)26Sortm1(Tbx1/GFP)Bem (Tbx1Cre/-;Tbx1-GFPflox/flox) mutants all have VSD, primarily with PTA and one example of DORV.
