Research Abstract

We attempted to visualize in vivo dynamic interactions between cancer stem cells (CSCs) and their surrounding stromal cells during the process of carcinogenesis, tumor invasion and metastasis in colorectal cancer using two photon laser scanning microscopy (TPLSM). We hypothesized that residual cancer cells after chemoradiotherapy (CRT) may contain putative CSCs which show not only CRT-resistant property, but also epithelial-mesenchymal transition (EMT) phenotype.
On liver metastasis model, dynamic tumor-host interactions including tumor-endothelial, tumor-platelet, and tumor-leukocyte interactions were observed in vivo real-time by TPLSM. Treatment resistant clones (made by repeated exposure of anti-cancer drug or irradiation) were inoculated into mice, and visualized their characteristics in vivo real-time using TPLSM. The small fraction of treatment resistant clones showed spindle shaped morphology. Their growth pattern was changed from localized growth to diffusely invasive growth.
