Three-dimensional cultured tissue constructs that imitate human living tissue organization for analysis of tumor cell invasion.

ABSTRACT: Preventing cancer metastasis requires a thorough understanding of cancer cell invasion. These phenomena occur in human 3-D living tissues. To this end, we developed a human cell-based three-dimensional (3-D) cultured tissue constructs that imitate in vivo human tissue organization. We investigated whether our 3-D cell culture system can be used to analyze the invasion of human oral squamous cell carcinoma (OSCC) cells. The 3-D tissue structure consisted of five layers of normal human dermal fibroblasts along with human dermal lymphatic endothelial cell tubes and was generated by the cell accumulation technique and layer-by-layer assembly using fibronectin and gelatin. OSCC cells with different lymph metastatic capacity were inoculated on the 3-D tissues and their invasion through the 3-D t
