Fig. 7. CaM KIV and BMP compete for limiting amounts of CBP. (A,C,E) The mean number (± s.e.m.) of WBCs (white bars), RBCs (black bars) and total blood cells (shaded bars) present in three random fields of cytospin blood preparations from tadpole stage embryos that had been injected with RNA encoding ß-galactosidase (control), mutant forms of CaM KIV, BMP and CREB, or wild type CBP, either alone or in combination, as indicated. (B,D,F) Average ratio of WBCs to RBCs (± s.e.m.), calculated from the data in A, C and E.
