Figure 9 Bright-field (a, c, and e) and dark-field (b, d, and f) micrographs of cross sections at three different levels through a stage 21 embryo probed for type II procollagen mRNA with the general probe. (a) and (b) are cut at a posterior level showing a high level of mRNA in the notochord. In addition, mRNA is detected throughout the somites and in the more dorsal half of the lateral plate mesoderm. c and d are cut at the level of the mid-gut showing that the signal is no longer detected in the lateral plate mesoderm but is restricted to the notochord and somites. e and f are cut at a more anterior level of the same embryo in which the intense signal in the notochord and sclerotome can be noted. The level of label in the remainder of the somite is relatively weaker than in the peri-notochordal region (n, notochord; s, somites). Bar, 250um. Image published in: Su MW et al.
