Figure 3. Enhanced eryptosis and adhesion of erythrocytes from annexin7-deficient mice following osmotic shock. A.

Figure 3

Histogram of annexin V-binding reflecting phosphatidylserine exposure in a representative experiment of erythrocytes from annexin7-deficient mice (anx7−/−) and their wild type control mice (anx7+/+) exposed for 2 hours to hyperosmotic shock (550 mM sucrose added). B. Arithmetic means ± SEM (n = 8−9) of the percentage of annexin V-binding erythrocytes from annexin7-deficient mice (anx7−/−, black bars) and their wild type control mice (anx7+/+, white bars) exposed for 2 hours to isotonic (left bars) or hyperosmotic (550 mM sucrose added, right bars) Ringer. ### significant (p<0.001) difference from isotonic Ringer, *** significant difference (p<0.001) from anx7+/+ erythrocytes (ANOVA). C. Arithmetic means ± SEM (n = 8−9) of the forward scatter of erythrocytes from annexin7-deficient mice (anx7−/−, black bars) and their wild type control mice (anx7+/+, white bars) exposed for 2 hours to isotonic (left bars) or hyperosmotic (550 mM sucrose added, right bars) Ringer. ### significant (p<0.001) difference from isotonic Ringer, *** significant difference (p<0.001) from anx7+/+ erythrocytes (ANOVA). D. Arithmetic means ± SEM (n = 6) of the number of erythrocytes from annexin7-deficient mice (anx7−/−, black bars) and their wild type control mice (anx7+/+, white bars) adhering to human umbilical vein endothelial cells (HUVEC) following exposure of the erythrocytes for 2 hours to isotonic (left bars) or hyperosmotic (550 mM sucrose added, right bars) Ringer. ### significant (p<0.001) difference from isotonic Ringer, *** significant difference (p<0.001) from anx7+/+ erythrocytes (ANOVA).
