Abstract :
[en] Interactions between tumor cells and basement membranes represent a critical step in the progression of neoplasia and in the metastatic process. Reconstituted basement membrane matrix, matrigel, has been recently used with the aim of developing an in vitro assay of tumor cell invasiveness. We have extended these studies by comparing the invasiveness of a large series of normal and malignant epithelial and mesenchymal cells of human and animal origin cultured on matrigel. Normal cells (fibroblasts, glomerular mesangial cells, keratinocytes), human fibrosarcoma cells (HT1080), and reticular sarcoma cells (M5076) clearly established invasive capabilities in the matrix. However, all the other tested cell lines, malignant or virally transformed cells invasive in vivo (MCF7, T47D, SA52, SW613, MO4, A431, BeWo), as well as normal nontransformed cells (MOH22) were incapable of penetration. The morphological features of matrigel invasion by normal fibroblasts and HT1080 cells are described at the light and electron microscope levels. The extent of degradation of a radiolabeled matrigel is minimal and similar in several cell lines reported to be noninvasive or invasive in vivo. Our data suggest that matrigel does not provide a universal model to correlate the invasiveness of cells in vivo and in vitro.
