and thus are separated from their native in vivo cellular environment. As a result of this human intervention, the recombinant DNAs, RNAs, polypeptides and proteins of the invention are useful in ways described
Either model does not rule out the possibility that early scl+ cells still retain the plasticity to form both blood and vascular lineages if transplanted or cultured in a suitable environment. Our experiments support a conserved role for cdx4 in the formation of hematopoietic cells during ...
