Fig. 3. Expression pattern and its schematic representation of BMPb (A,C) and chordin (B,D) at the 64-cell stage. (E) When A6.2/A6.4 were isolated at the 24-cell stage, they did not express chordin at the 64-cell stage. (F) BMP-4 induced chordin expression in A6.2/A6.4 isolated blastomeres. Scale bar: 100 µm.
