Evaluation
of the therapeutic effect of novel drug-loaded systems
in TAC-induced cardiac insufficiency in mice. (a) Experimental protocol
and dosing protocol of pre-established TAC-induced mouse stress overload
model. (b) Representative plot of mouse cardiac ultrasound 45 days
after construction of the TAC model. (c) Left ventricular ejection
fraction quantified by echocardiography. (d) Left ventricular minor
axis contraction (mean ± SD, n = 6). (e) Quantification
of fibrotic area in the sham group, TAC model group, and TAC with
different treatment group (mean ± SD, n = 6).
(g) Representative cross sections from remote LV stained with Sirius
red; scale bar = 100 μm. (f) Statistical plot of changes in
cardiomyocytes area stained with wheat germ agglutinin (WGA) (mean
± SD, n = 6) and (h) representative LV cross-section
stained with WGA, scale bar = 20 μm. *p <
0.05, **p < 0.01, and ***p <
0.001, one-way ANOVA, Tukey’s multiple comparison test.
