Fig. 2. Tak1 ${Delta}$ / ${Delta}$ embryos are abnormal by E9.5. (A-C) E9.5 embryos. (D-F) E10.5 embryos. (A,D) Tak1+/ ${Delta}$ control embryos. (B,C,E,F) Tak1 ${Delta}$ / ${Delta}$ embryos. The Class II Tak1 ${Delta}$ / ${Delta}$ embryo at E9.5 (B) is slightly reduced in size. The Class I Tak1 ${Delta}$ / ${Delta}$ embryo (C) is further reduced in size in comparison with the embryo in B, and has a pericardial edema (arrow). The less severely affected Tak1 ${Delta}$ / ${Delta}$ embryo at E10.5 (E) is reduced in size and has a small head. The more severely affected Tak1 ${Delta}$ / ${Delta}$ embryo at E10.5 (F) is severely reduced in size, and has localized areas of necrosis and a large pericardial edema (arrow).
