ABSTRACT
The developing vascular network is grown on the surface of chick embryo chorioallantoic membrane [CAM], so CAM is widely used as an in vivo model to study the angiogenesis. Because the CAM is hindered or wrinkled by the vehicle, the drug effect is difficult to be observed. In the present study, we firstly introduced the pluronic F127 aquogel to deliver drugs for the CAM model. The biocompatibility and advantage of this vehicle was shown by applied ranibizumab-pluronic F127 mix on the CAM. The results were showed that, the growth of blood vessels was not impaired by pluronic F127 gel, and the gel was almost imperceptible on the CAM, at the same time, the degradation of blood capillaries caused by ranibizumab was clearly visible. In conclusion, pluronic F127 was a good vehicle for angiogenesis research
