Figure 2. Ventral Injection of noggin mRNA Generates Partial Secondary Axes Normal embryos at the 4- to 8-cell stages were injected in a ventralvegetal position with 10 pg of noggin mRNA (A), 200 pg of noggin mRNA (B), or 5 pg of Xwnt-8 mRNA (C). Embryos were fixed at the late tailbud stage. The secondary axes generated by noggin (arrows in A and B) lack a cement gland; those in (C) possess well-developed cement glands (arrows). Note that embryos in (B) and (C) lack posterior structures. Image published in: Lemaire P et al. (1995) Copyright © 1995. Image reproduced with permission of the Publisher, Elsevier B. V.
