Neovascularization during the proliferation phase is best described as:

• A. Endothelial cell migration
• B. Vasculogenesis
• C. Angiogenesis
• D. Hemostasis

Answer: (C)

During the proliferative phase of wound healing, new blood supply is needed to nourish the growing tissue, so blood vessels reappear and expand into the wound bed. This neovascularization is best described as angiogenesis—the growth of new vessels from pre-existing ones, forming capillary networks within the granulation tissue. Endothelial cells near the injury proliferate and migrate, forming sprouts that extend into the wound and connect to create a vascular network, a process driven by hypoxia and factors like VEGF. Vasculogenesis, by contrast, involves formation of vessels from endothelial progenitor cells, which is more characteristic of embryonic development and some specific adult contexts, not the typical wound-healing scenario. Hemostasis is the initial clotting response after injury, not the development of new vasculature. So the description of neovascularization during the proliferation phase aligns with angiogenesis.
