Data sources Information included in this article was identified by searches of PUBMED and other online resources using the key terms DMD, dystrophin, mutations, animal models, pathophysiology, gene expression, stem cells, gene therapy, cell therapy, and pharmacological. Study selection Mainly original milestone articles and timely reviews written by major pioneer investigators of the field were selected. Results The key issues related to the genetic basis and pathophysiological factors of the diseases were critically addressed. The availabilities and advantages of various animal models for the diseases were described. Major molecular and cellular therapeutic approaches were also discussed, many of which have indeed exhibited some success in pre-clinical studies but at the same time encountered a number of technical hurdles, including the efficient and systemic delivery of a functional gene and myogenic precursor/stem cells to repair genetic defects. Conclusions Further understanding of pathophysiological mechanisms at molecular levels and regenerative properites of myogenic precursor/stem cells will promote the development of multiple therapeutic strategies. The combined use of multiple strategies may represent the major challenge as well as the greatest hope for the therapy of these diseases in coming years.展开更多

DATA RETRIEVAL： We performed a bibliometric analysis of studies on stem cell transplantation for treating Duchenne muscular dystrophy from 2002 to 2011 retrieved from Web of Science. SELECTION CRITERIA： Inclusion criteria： （a） peer-reviewed published articles on stem cell transplantation for treating Duchenne muscular dystrophy indexed in Web of Science; （b） original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items; and （c） publication between 2002 and 2011. Exclusion criteria： （a） articles that required manual searching or telephone access; （b） documents that were not published in the public domain; and （c） corrected papers. MAIN OUTCOME MEASURES： （1）Annual publication output; （2） distribution according to subject areas; （3） distribution according to journals; （4） distribution according to country; （5） distribution according to institution; （6） distribution according to institution in China; （7） distribution according to institution that cooperated with Chinese institutions; （8） top-cited articles from 2002 to 2006; （9） top-cited articles from 2007 to 2011. RESULTS： A total of 318 publications on stem cell transplantation for treating Duchenne muscular dystrophy were retrieved from Web of Science from 2002 to 2011, of which almost half derived from American authors and institutes. The number of publications has gradually increased over the past 10 years. Most papers appeared in journals with a focus on gene and molecular research, such as Molecular Therapy, Neuromuscular Disorders, and PLoS One. The 10 most-cited papers from 2002 to 2006 were mostly about different kinds of stem cell transplantation for muscle regeneration, while the 10 most-cited papers from 2007 to 2011 were mostly about new techniques of ste展开更多
