The severity of pulmonary fibrosis of allografts and isografts. Expression of HIF-1α, VEGF-A and VEGFR-2 is related to the severity of pulmonary fibrosis. a n = 10 (Iso) and n = 22 (Allo); b n = 32 (HIF-1α(−)) and n = 32 (HIF-1α(+)); c n = 40 (VEGF-A(−)) and n = 24 (VEGF-A(+)); d n = 32 (VEGFR-2(−)) and n = 32 (VEGFR-2(+)); All data shown are the mean ± standard deviation. ***p < 0.01 and ###p < 0.01 with T test. F score, The severity of fibrosis score; Iso, isograft; Allo, allograft; HIF-1α, Hypoxia inducible factor-1α; VEGF-A, vascular endothelial growth factor-A; VEGFR-2, vascular endothelial growth factor receptor-2; R, right lung; L, left lung
