The wound healing response involves all the following EXCEPT (choose the most
incorrect answer):
Initial blood clot formation is mediated by thrombin resulting in platelet
aggregation and fibrin clots.
Collagen deposition by vascular endothelial cells is critical in increasing the
tensile strength of repaired wounds to approximately 100%.
Angiogenesis involves the response of endothelial cells to growth factors such as
vascular endothelial growth factor (VEGF)
Activated fibroblasts produce collagen and fibronectin increasing the tensile
strength of wounds
Migration of fibroblasts in response to growth factors is an important
component of the proliferation phase
