Basement membrane and extracellular matrix degradation2. Endothelial migration3. Endothelial proliferation (mitosis)4. Organisation and maturation including the recruitment of vascular pericytes or smooth muscle cells5. Increased permeability due to intercellular gaps and increased transcytosis.Thrombosis - Formation of the blood clot (thrombus)Fibrosis - Repair by connective tissues
