Fig. 9. Rescue of the LR defects of Inv/Inv embryos by artificial nodal
flow. Both Inv/+ and Inv/Inv embryos were exposed to
artificial leftward flow as described previously
(Nonaka et al., 2002) and were
then examined for the directions of heart looping and embryonic turning. (A)
The numbers of embryos that exhibited normal or reversed heart looping or
embryonic turning, or outlooping of the heart or an unturned tail were
determined. (B,C) Examples of the rescued (B) and non-rescued (C)
Inv/Inv embryos are shown. Heart looping is indicated by the broken
lines. Scale bar: 1 mm.
