The pathology and expression level of plasma exosomal mmu_circ_0002687 of single does bleomycin-induced IPF mouse model. A–B The pathology of single does bleomycin-induced IPF mouse model. observation time points of bleomycin-induced mouse model at 7, 14, 21,35 and 49 days, CTL/0: mice without bleomycin treatment. A: Represent image (4x); B: statistic value of fibrotic area. C The expression level of plasma exosomal mmu_circ_0002687at 0, 7, 14, 21,35 and 49 days. 0 days means mice without bleomycin treatment (CTL). Five mice were at each time point. Each test was repeated three times. The mean differences were analyzed by Student’s t test. *P < 0.5;**P < 0.01;***P < 0.001
