FIG. 7. Addition of FGF posteriorizes neural cell fate in explants but does not expand the neural field. (A) XAG-1 staining (light blue) is
found next to the location of a glass bead, that was placed in the center of the explant (black arrow). Midbrain–hindbrain boundary marker
(En-2, red arrows, dark blue stain) in more posterior region. (B) In explants treated with 10 ng/ml basic FGF, En-2 (red arrow, dark blue stain)
occupies a region significantly closer to the glass bead. Cement glands are frequently absent. (C) Control (left) and FGF-treated (right)
explants stained for a panneural marker (nrp-1) show that FGF does not alter the expand the border of neural tissue. Image published in: Holowacz T and Sokol S (1999) Copyright © 1999. Image reproduced with permission of the Publisher, Elsevier B. V. Larger Image Printer Friendly View |
