The present invention relates to methods and compositions for promoting or inhibiting capillary endothelial (CE) cell migration, promoting or inhibiting the formation of CE networks and promoting or inhibiting angiogenesis. Some embodiments relate to methods and compositions for treating angiogenesis-related disorders characterized by loss or decreased angiogenesis. One aspect relates to the use of at least one pro-angiogenic agent selected from at least one of an p190RhoGAP inhibitor, a TFII-I inhibitor or a GATA-2 activator for promoting the formation of CE networks and angiogenesis, and methods for treating angiogenesis-related disorders characterized by loss or decreased angiogenesis. Another aspect of the invention related to use of at least one anti-angiogenic agent selected from at least one of an p190RhoGAP activator, a TFII-I activator or a GATA-2 inhibitor for inhibiting the formation of CE networks and inhibiting angiogenesis, and methods for treating angiogenesis-related disorders characterized by uncontrolled or elevated angiogenesis.
