Abstract: | We have developed an improved assay for the production of collagen by fibroblasts. Early passage adult mouse lung fibroblasts, established and maintained in serum-free culture, were employed as the target cells. An enzyme immunoassay was used for detection of type I collagen deposited on the substratum, permitting adaptation of the technique to cultures in 96-well microplates. Approximately two-fold enhancement of collagen deposition was induced by exposure to a concentration of 3 ng/ml of transforming growth factor-β1 or of 100 ng/ml of insulin-like growth factor-1 for 48 hr. |
