The cancer stem cell theory hypothesizes that cancer stem cells (CSCs), which possess self-renewal and other stem cell properties, are regarded as the cause of tumor formation, recurrence and metastasis. The isolation and identification of CSCs could help to develop novel therapeutic strategies specifically targeting(More)
MicroRNAs (miRNAs) play important roles in post-transcriptional gene silencing of target messenger RNAs, which are involved in virtually all biological processes. Previously, we have demonstrated that spheroid body-forming cells from the MKN-45 cancer cell line possessed gastric cancer stem cell (CSC) properties. In this study, we aimed to determine the(More)
The cancer stem cell (CSC) theory hypothesizes that CSCs are the cause of tumor formation, recurrence and metastasis. Key to the study of CSCs is their isolation and identification. The present study investigated whether spheroid body-forming cells in the human gastric cancer (GC) MKN-45 cell line are enriched for CSC properties, and also assessed the(More)
