Dual Effects of Hypoxia-Inducible Factors-1 Alpha in Bleomycin-Induced Pulmonary Fibrosis Treated by Human Umbilical Cord Mesenchymal Stem Cells

Figure 3

Preventive administration of HUCMSCs can effectively attenuate pulmonary fibrosis induced by bleomycin in A549 cells. (a) Results of immunofluorescence staining in A549 cells of the control, CM-pretreatment, CM-treatment, belomycin, belomycin+CM-pretreatment, and belomycin+CM-treatment groups. TP53BP1 are stained in A549 cells with antibodies (red). Nuclei are stained with DAPI (blue). μm. (b) Results of western blot in the same groups. (c) Results of qPCR in the same groups. Data are presented as . , vs. the control; #, ## vs. the model.
