Gene expression profile in HUVECs before and after Angiopoietin stimulation

Angiopoietin-Tie2 sytem has been inplicated in both vascular quiescence and angiogenesis. It is unclear how these two opposing signals are regulated from the same receptor-mediated intracellular signal transduction. We have noticed that Tie2 localization upon Angiopoietin stimulation depends upon the presence or absence of cell-cell contacts.
