Mechanisms of cholangiocyte responses to injury

Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2018
Cholangiocytes, epithelial cells that line the biliary epithelium, are the primary target cells for cholangiopathies including primary sclerosing cholangitis and primary biliary cholangitis. Quiescent cholangiocytes respond to biliary damage and acquire an activated neuroendocrine phenotype to maintain the homeostasis of the liver. The typical response

Direct Visualisation of the Depth-Dependent Mechanical Properties of Full-Thickness Articular Cartilage. [PDF]

, 2012
The structural anisotropy of articular cartilage controls its deformation response. As proteoglycans and collagen vary with depth, simple uniaxial compression results in inhomogeneous deformation with distinct depth-dependent mechanical properties ...
