Protocols for investigating microRNA functions in human neural progenitor cells.
Human embryonic stem cells and induced pluripotent stem cells offer great hope for studies of pathogenic mechanisms of disease and cell-based therapies. One powerful approach to manipulate the behaviors of human stem cells and their progenies is through microRNAs (miRNAs), a class of small noncoding RNAs that regulate gene expression at the posttranscriptional level. Each miRNA may target up to hundreds of mRNAs; some are specifically expressed in progenitor cells and affect multiple cellular processes. Here we present experimental protocols for investigating the endogenous functions of specific miRNAs in the proliferation, survival, and migration of human neural progenitor cells derived from embryonic stem cells. These methods may be applicable to protein factors and neural progenitor cells derived from patient-specific induced pluripotent stem cells.
