Fig. 2 All deep cells are competent to respond to a mesoderm-inducing signal such as activin. (A) Scheme of the experimental procedure. (B) Explants of the central deep cells dissected at sphere stage and cultured until siblings had reached shield stage show no endogenous expression of Ntl. (C) Explants of the central deep cells cultured in activin (8 U/ml) show Ntl expression in all cells. (D) Explants of the marginal blastomeres and animal caps show endogenous Ntl expression only in the marginal explants. (E) Explants of marginal blastomeres and animal caps cultured in activin (8 U/ml) show Ntl expression in all cells. Scale bars: 100 μm.
