TY - GEN AB - Primitive hematopoiesis in Xenopus requires signals from both mesoderm and neighboring ectoderm, yet the molecular regulators of these ectodermal signals are not fully defined. This study demonstrates that the transcription factor GATA-2 is required in the ectoderm for normal blood development. Loss of GATA-2 function produces hematopoietic defects similar to those caused by disruption of BMP signaling or CaMKIV activity. The data support a linear pathway in which BMPs induce GATA-2 transcription, while CaMKIV negatively regulates GATA-2 activity post-translationally, revealing a coordinated mechanism controlling early blood lineage specification.
