Abstract:
The collagen contraction assay is an in vitro, three-dimensional method to determine the factor(s) affecting the contractile behavior of activated cells such as fibroblasts in either physiological or pathological scenarios. The collagen lattices/hydrogels are seeded with fibroblasts to mimic the interactions between these cells and their surrounding extracellular matrix proteins in the connective tissue. This method is an important platform to assess components as potential therapeutic targets to prevent pathologies such as fibrosis, which are manifestations of hyperactivated fibroblasts. We have described a basic version of this collagen contraction assay, which is amenable to customization using different cell types under diverse experimental conditions.
