KV morphogenesis and left-sided Nodal signaling in apela morphants. (A-B) In control, 91.2% of embryos showed normal KV (A, n=136), but 37.6%, 53.3% and 9.1% of embryos injected with apela MO showed normal KV, mild smaller KV and no KV, respectively (B, C and D. column2, n=178). (C. c1-c5, D) Majority of control morphants expressed left-sided spaw in the LPM (C. c1, D left column, 91.4%, n=35). In apela MO morphants, 31.3%, 13.9% and 16.3% of embryos showed left-sided spaw, right-sided spaw and both-sided spaw (C. c2-c4, D middle column, n=30), while the spaw expression in most of apela morphants couldn't be found (C. c5, D middle column, 38.9%, n=86). (E-F) The Nodal downstream gene lft2 was checked. Compared with that in control embryos (E. e1, F right column, 94.2%, n=52), lft2 was down regulated and the left-sided expression pattern was disturbed in apelamorphants (E. e2-e4, F middle column, n=39), displaying left-sided (17.9%), right-sided (10.25%), both-sided (5.12%) expression and the expression disappeared (66.7%). The disturbed KV morphogenesis and the perturbed spaw or lft2 expression were also observed in apln morphants (D, D, F, right column). |
