Zinc ions inhibit migrasome biogenesis and impair platelet function by targeting cholesterol and sphingomyelin

Figure 5. Effects of zinc gluconate on migrasomes and platelet dynamics in mice. (A) Zinc gluconate treatment inhibited migrasome formation in mouse blood. Scale bar: 40 µm; (B) Statistical analysis based on (A) (n = 11 mice per group); (C) Platelet counts in mouse blood before and 24 h after zinc gluconate treatment were statistically evaluated (n = 6 mice per group); (D) Images representative of aggregated platelets in blood smears from zinc gluconate-treated mice. Scale bar: 40 µm; (E) Evaluation of peripheral vascular bleeding after 24 h of zinc gluconate treatment in mice (n = 6 mice per group); (F) Statistical analysis of the data in (E); (G) Peripheral vascular bleeding in mice after 24 h of zinc gluconate treatment vs. untreated controls (n = 6 mice per group). Values are mean ± SEM. **P < 0.01; ****P < 0.0001; (H) Diagram illustrating the effect of reduced migrasome levels on blood clotting. SEM: Standard error of the mean.
