[摘要]：Induced pluripotent stem (iPS) cells have been generated from somatic cells by ectopic expression of defined transcription factors. The important issues for clinical applications of iPS cells are the defined methods for somatic cell differentiation and how to effectively enrich desired cell population. Here we used humanized renilla green fluorescent protein under the control of T alpha 1 alpha-tubulin promoter as lineage selection marker for neuronal differentiation of iPS cells. Using fluorescence-activated cell sorting, green fluorescent protein positive cells were isolated and enriched to near-purity. These results indicated that the neuronal differentiation potential of iPS cells derived from adult somatic cells is similar to that of embryonic stem cells and the high-purity neurons may have important implications for neurodevelopmental studies, safety pharmacological studies, and transplantation studies.
