Larger Image Fig. 7. Rescue of BMP-4 morpholino effects on Hox gene expression by BMP-4 protein treatment. (A) In situ hybridisation of stage 11 embryos for Hoxd-1. Shown are ventral views of a noninjected embryo (A), an embryo ventrally injected with 30 ng of BMP-4 morpholino (B) and an embryo ventrally coinjected with 30 ng of BMP-4 morpholino and 3 ng of BMP-4 protein. (D) Table showing the numbers of the rescue experiment. Using the v2 test to compare BMP-4 morpholino injection to BMP-4 morpholino + BMP-4 protein injection, the rescue is significant at a significance level of a V 0.01.
