Fig. 6. Effects of injection of mRNAs for HrFGFR or dnHrFGFR on expression of endoderm-specific AP (A-A''), muscle-specific AChE (B-B"), epidermis-specific HrEpiC gene (C-C''), and notochord-specific HrBra (D-D'',E-E'') and Not1 antigen (F-F''). Development of the first three markers and the Not1 antigen was examined at the mid-tailbud stage (A-C,F), while that of HrBra was examined at the 110-cell (D-D'') and initial tailbud stages (E-E''). (A-E) control, uninjected embryos, (A'-E') embryos injected with HrFGFR mRNA; (A''-E'') embryos injected with dnHrFGFR mRNA.
