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. O 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

Tissue regeneration & repair

Tissue regeneration involves the restoration of tissue components by regrowth of damaged tissues. In contrast, tissue repair involves patching of injured tissue rather than restoring it. It is the proliferative capacity of the cells that decides the amount of regeneration against the repair that would occur in the tissue. Both regeneration and repair depending on the duration of the injury and response to the inflammation.
