Figure 5: Biomechanical properties of triple-knockout porcine pericardium are similar to those of wild-type pig pericardium.

Figure 5:

Uniaxial stress test of wild-type (WT) and triple-knockout (TKO) pig pericardium (n = 3/group).

(A) Pericardium was harvested from 6 WT and 6 TKO pigs and tested for stress strain.

(B) Box plot of the maximum stress (10.56±4.39 MPa and 13.54 ± 2.61 MPa for the WT and TKO, respectively).

(C) Box plot of the strain at the maximum stress (WT was 74.62±12.43%, TKO was 67.81±6.44%).

(NS = not significant; TKO = triple-knockout (GTKO/β4GalNT2-KO/CMAHKO); WT = wild-type) (Reproduced from Zhang and colleagues [37] with permission from Elsevier)
