Fig. 5. CaM KIV antagonizes hematopoietic functions of BMPs downstream of receptor activation. (A,C) 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 at least 30 control embryos or embryos injected with RNA encoding mutant forms of BMP and/or CaM KIV as indicated: caKIV, constitutively active form of CaM KIV; caKK, its upstream kinase; DnKIV, dominant negative form of CaM KIV. (B,D). The average ratio of WBCs to RBCs (± s.e.m.), calculated from the data in A and C.
