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. WebSep 1, 2024 · The loss of matrix caused the shrink of microtissue size by over 80%, showing that the collagen component composed the main part of the microtissue volume (Fig. 4 A and E and Movie S6). The maximum force dropping due to the loss of the collagen matrix was about 4 µN ( Fig. 4 D ), which was close to the residual force after cytoD …
