Effect of depletion of CD34 + cells in myocardial fibrosis. A Schematic showing CD34-CreERT2;Rosa26-tdTomato/DTA mice. Experimental scheme whereby Cre/DTA mice were given tamoxifen for 1 weeks before TAC 0 or TAC surgery. Heart tissue was harvested 4 weeks after TAC surgery. B Representative echocardiography of mice between CD34-CreERT2;Rosa26-tdTomato (Control) and CD34-CreERT2;Rosa26-tdTomato/DTA (Cre/DTA) at 4 weeks after TAC surgery. C Echocardiographic measurement of left ventricle ejection fraction (EF) and fractional shortening (FS) of control group and Cre/DTA group after 4 weeks TAC surgery, Data represent mean ± SEM, Cre/DTA group, n = 17; Control group, n = 23. D ELISA detection of the serum ANP and BNP between control group and Cre/DTA group after 4 weeks TAC surgery, Data represent mean ± SEM, n = 15 per group. E Representative immunostaining images showing staining of tdTomato and vimentin, DDR2 in control group and Cre/DTA group (Scale bar = 20 μm and 100 μm). n = 10 per group. F Graph showing percentage of tdTomato expression in vimentin + , DDR2 + fibroblast. Data represent mean ± SEM, n = 10
