Abstract
This book chapter describes the use of exogenous application of lysyl oxidase (LOX) and bone morphogenetic protein-1 (BMP1) to enhance collagen synthesis and deposition from fibroblasts in culture. The protocol includes the generation of human embryonic kidney (HEK) 293 cell lines overexpressing human LOX and BMP1 constructs in order to obtain supernatants enriched in these factors. Incubation of fibroblast monolayers with these conditioned media strongly increases the capacity of these cells to deposit collagen onto the insoluble extracellular matrix. We also describe the use of these decellularized fibroblast-derived matrices as a substrate for the growth and differentiation of mesenchymal stem cells.
