 Wnt8 and BMP input on tailbud progenitor specification. All images: posterior views, dorsal up, 5-6 somite stage. A–D: myf5 expression marks presomitic mesoderm and somites, but is excluded from a small region of the ventral tailbud (arrow in A). Expression is significantly reduced in wnt8 morphant (B; inset: dorsal view). Note expansion of myf5-free progenitor zone in chordin morphant (C, outlined by arrowheads), and smaller expansion in wnt8;chordin morphants (D). E-H: msgn expression mirrors the behavior of the myf5-free zone of the tailbud.  |
