Expression density (mean fluorescence intensity, MFI) and percentage of lung ECs (luECs in vivo) from C57BL/6 mice cells expressing antigens associated with repair and angiogenesis mechanisms. (A) VE-cadherin and (B) Endoglin expression on CD31+/CD45− lung ECs (luECs in vivo) isolated from C57BL/6 mice, 2 and 10 weeks after sham irradiation (0 Gy, brown column), partial irradiation of the lung (20% of the total lung volume) with 16 Gy (yellow column), or partial lung irradiation after a treatment with CBD (i.p. 20 mg/kg body weight per day for 4 weeks, 2 weeks before and 2 weeks after lung irradiation, blue column); data represent mean values ± SD of 3–4 mice (n = 3–4); * p < 0.05, ** p < 0.01 and *** p < 0.001.
