To test whether the actin cytoskeleton is modified along with the changes in BC during regeneration, we quantified the levels of apical F‐actin (phalloidin, Fig 2A, Appendix Fig S2A) and phospho‐Myosin light chain (pMLC, Fig 2C, Appendix Fig S2B) at the apical area of hepatocytes at different time points after PH or sham operation. Here, MYH14 is linked to breast cancer.
