Summary
The molecular mechanisms regulating the development of vascular diseases such as atherosclerosis
remain poorly understood at present. Similarities between genetic programs observed
during the course of vascular disease with those observed during vascular development
suggest that developmental processes are recapitulated in vascular disease. The earliest
event in vascular development is the differentiation of endothelial cells from their
mesodermally-derived hamangioblastic precursors. The receptor for vascular endothelial
growth factor, KDR/flk-1, plays a critical role in these earliest stages of vascular
development. During development and in the adult, expression of this receptor is restricted
to vascular endothelial cells and their immediate precursors. We have therefore endeavored
to determine the transcriptional events regulating KDR/flk-1 expression, with the
hope of gaining insight into processes of vascular development that might also be
important in vascular diseases of the adult.
