Metazoan growth and development is maintained by populations of undifferentiated cells, commonly known as stem cells. Stem cells possess several characteristic properties, including dividing through self-renewing divisions and generating progeny that differentiate to have specialized cell fates. Multiple signaling pathways have been identified which coordinate stem cell proliferation with maintenance and differentiation. Relatively recently, the small, non-protein coding microRNAs (miRNAs) have been identified to function as important regulators in stem cell development. Individual miRNAs are capable of directing the translational repression of many mRNAs targets, generating widespread changes in gene expression. In addition, dysfunction of miRNA expression is commonly associated with cancer development. Cancer stem cells, which are likely responsible for initiating and maintaining tumorigenesis, share many similarities with stem cells and some mechanisms of miRNA function may be in common between these two cell types.
