Embryos from the pCMV-rAct-injected mice. (A) The two surgically isolated embryos at left were obtained at E15.5 from a pCMV-rAct-injected female mouse, one of which was dead (pCMV-rAct 1) and the other of which was atypically large (pCMV-rAct 2). Tissues of the embryos were observed at 6× magnification under the stereomicroscope (Leica ME Apo). (B) The embryos were weighted at E15.5. The number of embryos from control and the pCMV-rAct-injected female mice is 48 (N = 48), and 100 (N = 100), respectively. Asterisks denote values that were significantly different from control mean values (Student's t-test, *, p < 0.01)
