Cannabinoid receptor type 1 (CBR-1) has been shown to increase during the stimulation of the angiogenesis process. HBEC-5i cells were cultured in proangiogenic media supplemented with bFGF (10 ng/mL) for 24, 48, and 72 h. (A) Western blot images were obtained, and densitometric analysis of the CBR-1 bands was conducted using ImageJ software. (B) Quantitative analysis of the CBR-1 expression rates. Data are presented as mean ± SEM (n = 3). (**) indicates p < 0.01. (***) indicates p < 0.001. (****) indicates p < 0.0001
