Hematopoiesis - the process by which blood cells are formed - has been studied intensely for over a century using a variety of model systems. There is conservation of the overall hematopoietic process between vertebrates, although some differences do exist. Over the last decade, the zebrafish has come to the forefront as a new model in hematopoiesis research, as it allows the use of large-scale genetics, chemical screens and transgenics. This comparative approach to understanding hematopoiesis has led to fundamental knowledge about the process and to the development of new therapies for disease. Here, we provide a broad overview of vertebrate hematopoiesis. We also highlight the benefits of using zebrafish as a model.

The Zon laboratory aims to dissect how assaults to the hematopoietic system cause severe diseases such as leukemias, lymphomas, and anemias. They investigate hematopoietic development and disease using chemical screens, genetic screens, and analysis of novel transgenic lines in zebrafish.
