Cell transplantation/replacement therapy is attractive as a novel strategy for neurological diseases such as Parkinson’s disease, Alzheimer’s disease, and stroke. To realize this therapy, safer and more therapeutic effective cell resources are now required. Since induced pluripotent stem cells (iPSCs) can retain high replication competence and pluripotency when they differentiate into various kinds of cells, they are regarded as a promising cell source for cell transplantation therapy. However, high tumorigenesis of iPSCs has to be overcome for clinical applications. Recent progress includes the combination of novel transcriptional factors that can convert somatic cells to various kinds of mature neuronal cells and neural stem cells without requiring iPSC fate. Some evidence indicates that these directly induced neuronal cells have little tumorigenic potential. In this article, we discuss the advantage, issues, and possibility of clinical application of these cells for cell transplantation therapy.

More about this publication?
  • Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
