Strawberries provide various vital natural substances which have a significant role in human health and disease prevention. In our study, we have focused on the effect of strawberry juice on angiogenesis using chicken chorioallantoic membrane (CAM) assay. Fresh fertilized eggs were taken, sprayed with 70% ethanol and incubated at 37 °C (humidity 55-60%). At day 5 of incubation a small window was made on each egg, 4-5 ml of albumen was removed, windows were sealed with sterile parafilm and eggs were returned to incubator. Strawberry juice was obtained from fully ripened strawberry fruits and various dilutions were prepared in distilled water. Filtered dilutions of the juice were used for experimental analysis and applied to the CAMs on day 6. of incubation. Macroscopic vascular changes were evidently observed among all treated CAMs on day 7 of incubation. Reduction in the total area and diameter of primary, secondary and tertiary blood vessels was observed after treatment with strawberry juice in concentration dependent manner. By using SPIP software 3D surface roughness measurements were carried out which clearly elaborated antiagiogenic effect of strawberry juice on CAMs. Strawberry juice inhibits angiogenesis, which is a common denominator shared by various major disease.

Angiogenesis, the formation of new blood vessels, is a hallmark of almost all neoplastic and non-neoplastic degenerative diseases.
