RHOA and hepatocellular carcinoma: Particularly, the endothelial monolayers cultured on HCC gels generated the highest level of stresses (2.8‐fold increase in total force compared to control, p‐value = 7.1 × 10−5, Figure 2g), while downregulating RhoA in ECs led to the lowest level of traction forces (71% decrease in total force compared to control, p‐value = 1.76 × 10−4, Figure 2g).
