title: Effect of transforming growth factor beta on fibroblasts in three-dimensional lattice cultures.
abstract: Human skin fibroblasts were cultivated in three-dimensional fibrin or collagen lattices, under retracting or non-retracting conditions, and the influence of transforming growth factor beta (TGF beta) was tested. TGF beta stimulated the synthesis of non-collagen protein and of collagen in all the systems. However, only in non-retracting fibrin lattices did it restore a level of protein synthesis comparable to that found in monolayers. The effects of TGF beta greatly depended on the type of substratum and on the presence or absence of retraction.
