TLDR
In this paper, the authors demonstrate that fibroblasts associated with carcinomas stimulate tumor progression of initiated nontumorigenic epithelial cells both in an in vivo tissue recombination system and in vitro coculture system.Abstract:
The present study demonstrates that fibroblasts associated with carcinomas stimulate tumor progression of initiated nontumorigenic epithelial cells both in an in vivo tissue recombination system and in an in vitro coculture system. Human prostatic carcinoma-associated fibroblasts grown with initiated human prostatic epithelial cells dramatically stimulated growth and altered histology of the epithelial population. This effect was not detected when normal prostatic fibroblasts were grown with the initiated epithelial cells under the same experimental conditions. In contrast, carcinoma-associated fibroblasts did not affect growth of normal human prostatic epithelial cells under identical conditions. From these data, we conclude that in this human prostate cancer model, carcinoma-associated fibroblasts stimulate progression of tumorigenesis. Thus, carcinoma-associated fibroblasts can direct tumor progression of an initiated prostate epithelial cell.read more

TL;DR: Using a coimplantation tumor xenograft model, it is demonstrated that carcinoma-associated fibroblasts extracted from human breast carcinomas promote the growth of admixed breast carcinoma cells significantly more than do normal mammaries derived from the same patients.
Journal ArticleDOI
Microenvironmental regulation of metastasis
TL;DR: Experimental data demonstrating the role of the microenvironment in metastasis is described, areas for future research are identified and possible new therapeutic avenues are suggested.

TL;DR: Comparative genomic hybridization produces a map of DNA sequence copy number as a function of chromosomal location throughout the entire genome, which identified 16 different regions of amplification, many in loci not previously known to be amplified.

TL;DR: The nucleotide sequence of the human HGF cDNA reveals that both α- andβ-chains are contained in a single open reading frame coding for a pre-pro precursor protein of 728 amino acids, which indicates that the activity of HGF is not species-specific.

Transforming growth factor-beta 1 induces alpha-smooth muscle actin expression in granulation tissue myofibroblasts and in quiescent and growing cultured fibroblasts.
TL;DR: It is shown that the subcutaneous administration of transforming growth factor- beta 1 to rats results in the formation of a granulation tissue in which alpha-SM actin expressing myofibroblasts are particularly abundant, suggesting that TGF beta 1 plays an important role in my ofibroblast differentiation during wound healing and fibrocontractive diseases by regulating the expression of alpha- SM actin in these cells.

TL;DR: The suggestion is that stromelysin-3 is one of the stroma-derived factors that have long been postulated to play an important part in progression of epithelial malignancies.
