Over the last few years, microRNAs (miRNA)-controlled cancer stem cells have drawn enormous attention. Cancer stem cells are a small population of tumor cells that possess the stem cell property of self-renewal.

MicroRNAs are the non-coding RNAs which regulate endogenous gene expression in animal and plant cells. Alterations in the level of micro-ribonucleic acids (miRNAs) involving the deletions, overexpression, mutations, epigenetic silencing, or dysregulation of transcription factors that target specific miRNAs may culminate in various diseases including cancer.
