Collagen degradation matrix stiff soft
WebFeb 21, 2024 · eLife 11 :e77041. When our bodies heal following an injury, fibroblasts and other cells deposit components of the extracellular matrix, such as collagen, that form a ‘scar’ over the damaged area. This process, known as fibrosis, leads to a build-up of stiff fibrotic tissue that interferes with the activity of the underlying organ. WebApr 13, 2024 · Noteworthingly, in this study, we varied the collagen concentration to tune the stiffness of the subendothelial matrix. However, increased collagen concentration may also affect a wide range of biophysical factors including fiber dimensions (length [ 56 ] and diameter [ 40 , 57 ] ), fiber density, [ 58 ] pore size, [ 57 ] and interconnectivity ...
