Abstract
The CAM model enables an in vivo analysis of the individual sub-steps of the metastatic cascade like local invasion, intravasation, or the establishment of metastasis in particular organs. Incubated fertilized chicken eggs are inoculated with human tumor cells and further processed for up to 9–10 days. The invasion and metastasis of these cells is then detected quantitatively with high specificity and sensitivity by means of a PCR for human ALU sequences, using the genomic DNA isolated from distant portions of the CAM, as well as from diverse internal organs of the developing embryo.
