Preface At present, research in the areas of stem-cell biology, RNA interference (RNAi), and microRNAs (miRNAs) is the source of immense scientific and medical interest. Despite their apparent differences, stem-cell biology, RNAi, and miRNA are increasingly being shown to have a great deal in common. Small RNAs, particularly those represented by miRNAs and RNAi, play a central role in the regulation of embryonic and adult stem-cell development. Recent research has revealed that in stem cells, miRNA- and RNAi-mediated gene regulation is one of the determinates controlling the state of cell differentiation, with the small RNAs serving as key elements involved in regulatory network control of pluripotent cell-fate determination. From a technological perspective, RNAi and miRNA-based methods are being developed both to study the processes of stem-cell differentiation and create clinically useful therapies for the treatment of disease and preservation of wellness. The promise is that harnessing the stem-cell regulatory activities of RNAi and miRNA will lead to rapid advancement in the use of these small RNA molecules as therapeutic agents in ar
