Human umbilical cord mesenchymal stem cells reduce platelet α-granule release in rats via the AKT/MEK/ERK pathway during acute exposure to high-altitude hypoxia

Figure 3 Expression levels of von Willebrand factor, platelet factor 4, and beta-thromboglobulin. A: Expression of von Willebrand factor in the different groups; B: Expression of platelet factor 4 in the different groups; C: Expression of beta-thromboglobulin in the different groups. n = 8 in each group. ^aP < 0.05, ^bP < 0.01, ^cP < 0.001, ^dP < 0.0001. vWF: von Willebrand factor; hUC-MSC: Human umbilical cord mesenchymal stem cell; PF4: Platelet factor 4; β-TG: Beta-thromboglobulin.
