FIG. 3. The expression profiles of FOR in the developing Xenopus
embryos. FOR expression was examined by whole mount in situ
hybridization using digoxigenin-labeled antisense riboprobe. The expression
of FOR is limited to the presumptive liver region indicated by
the white arrowhead. Panels A, C, and E are lateral views of developing
embryos and B, D, and F are ventral views, respectively. A and B,
embryos at stage 30 (mid-tail bud stage). The FOR expression begins to
be detected from this stage in the presumptive liver region (indicated by
the white arrowhead). C and D, embryo at stage 35. The FOR expression
in the embryo reaches a peak level at this stage. Note more intense
staining in the broader expression domain compared with the embryos
at stage 30. E and F, embryos at stage 41. The FOR expression declines
remarkably at this stage. |
