Fig 7. rbp7a and spaw function together in left-right development.

Panel A: Injection of rbp7a (blue bars) or spaw (purple bars) morpholinos at standard concentrations results in significantly altered spaw expression. Panel B: Injection of either morpholino at subthreshold doses (rbp7a: blue bars; spaw: purple bars) results in more normal left-sided spaw expression. However, co-injection of both morpholinos at subthreshold doses leads to significantly altered spaw expression, similar to the higher dose spaw morphants.
