Figure 6. Xnr3 Lacks Direct Mesoderm-Inducing Activity
(Top) We injected l-cell embryos with Xnf3 or activin RNAs. Animal
caps were dissected at stage 6 (midblastula) and grown to stage 20
(early tailbud). RNA was assayed for muscle actin expression by
RNase protection assay. Each sample had ten animal caps. The lane
marked /acZ RNA is 6galactosidase RNA.
(Bottom) Embryos were injected at l-cell stage with XnA RNA, Xnr3
expression plasmid (Xnr3-pXEX), or activin RNA. Animal caps, prepared
as in (A), were analyzed at stage 11 for expression of Brachyury
by RNase protection assay. Image published in: Smith WC et al. (1995) Copyright © 1995. Image reproduced with permission of the Publisher, Elsevier B. V. Larger Image Printer Friendly View |
