Fig. 7. Overexpression of Xdsh mRNA leads to
neuralization of animal cap explants. Animal caps
from embryos injected with 1 ng of Xdsh RNA
were explanted from the injected embryos at stage 8
and cultured in isolation until the equivalent of
stage 31 (A) or stage 11 (B). After culture, the
explant RNA was extracted and analyzed by
northern blotting using different 32P-labeled
antisense RNA probes. RNA from ten animal cap
equivalents or from two embryos is loaded per lane.
The same blot was stripped and reprobed with different probes. Two major specific transcripts of
NCAM are shown (Kintner and Melton, 1987). EF1a and fibronectin probes are controls for loading.
The muscle-specific actin probe weekly cross-hybridizes with cytoskeletal actin RNAs (the two bands
above muscle-specific band). Lane 1, animal caps from embryos injected with 1 ng of Xdsh mRNA;
lane 2, animal caps from embryos injected with 0.12 ng of noggin mRNA; lane 3, control animal caps
from uninjected embryos; lane 4, sibling embryos, stage 31 (A) or 11 (B). Image published in: Sokol SY et al. (1995) Copyright © 1995.
