The invention belongs to the technical field of biology, and particularly relates to endothelial cell culture solution. The endothelial cell culture solution comprises a basic culture medium DMEM (dulbecco modified eagle medium), human platelet lysate, L-glutamine, vitamin C, laminin 10, laminin 11, fibronectin, penicillin and streptomycin. The endothelial cell culture solution has the advantages that a pH (potential of hydrogen) value of the endothelial cell culture solution is 6.8-7.0, and the osmotic pressure of the endothelial cell culture solution is 310 mOsm/kg; endothelial cells cultured by the endothelial cell culture solution are high in adherence and proliferation speed, purity, migration capacity and lumen formation rate, invasion effects of the endothelial cells can be inhibited, and accordingly the endothelial cell culture solution is a perfect endothelial cell culture system.
