cebpa loss-of-function phenotype. X tropicalis embryos injected with control MO (10 ng; A, C, E, G, I, K) or cebpaATG MO (10 ng; B, D, F, H, J, L), fixed at stage 23 and analyzed by whole mount in situ hybridization for the myeloid markers mpo (A, B), lcp (C, D), mmp7 (E, F), spi1 (G, H), spib (I, J), and cebpa (K, L). All images are lateral views, anterior to the left. The ratio of embryos showing the phenotype is shown in the bottom right corner of each image.
