POTENTIAL THERAPEUTIC APPLICATIONS OF DIFFERENTIATED INDUCED PLURIPOTENT STEM CELLS (iPSCS) IN THE TREATMENT OF NEURODEGENERATIVE DISEASES

摘要

Abstract-Difficulties in realizing persistent neurogenesis, inabilities in modeling pathogenesis of most cases, and a shortage of disease material for screening therapeutic agents restrict our progress to overcome challenges presented by neurodegenerative diseases. We propose that reprogram-ming primary somatic cells of patients into induced pluripo-tent stem cells (iPSCs) provides a new avenue to overcome these impediments. Their abilities in self-renewal and differentiation into various cell types will enable disease investigation and drug development. In this review, we introduce efficient approaches to generate iPSCs and distinct iPSCs differentiation stages, and critically discuss paradigms of iPSCs technology application to investigate neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). Although iPSCs technology is in its infancy and faces many obstacles, it has great potential in helping to identify therapeutic targets for treating neurodegenerative diseases. ? 2012 IBRO.
