The chemotactic migration of transformed cells out of their tissue of origin might represent an essential component of tumor invasion and metastasis. In the Boyden chamber assay SV 40 virus-transformed BALB-c3T3 fibroblast (SV/3T3) showed an increased chemotactic response to fibroblasts-conditioned medium in comparison to non-transformed BALB/c3T3 cells. This was verified for a large range of incubation times and cell densities. Fibroblast-conditioned medium contains components of the extracellular matrix of connective tissue. Since organs rich in connective tissue are often the site of metastasis, the enhanced chemotaxis of virus-transformed cells to conditioned medium could contribute to explain the malignancy of these cells.
