ABSTRACT
Embryonic zebrafish have long been used for lineage-tracing studies. In zebrafish embryos, the cell fate identities can be determined by whole-mount in situ hybridization, or by visualization of live embryos if using fluorescent reporter lines. We use embryonic zebrafish to study the effects of a leukemic oncogene AML1-ETO on modulating hematopoietic cell fate. Induced expression of AML1-ETO is able to efficiently reprogram hematopoietic progenitor cells from erythroid to myeloid cell fate. Using the zebrafish model of AML1-ETO, we performed a chemical screen to identify small molecules that suppress the cell fate switch in the presence of AML1-ETO. The methods discussed herein may be broadly applicable for identifying small molecules that modulate other cell fate decisions.
