The increasing number of publications featuring the use of stem cells in regenerative processes supports the idea that they are revolutionizing regenerative medicine research. In an analysis of the articles published in the journal Cell Transplantation - The Regenerative Medicine Journal between 2008 and 2009, which reveals the topics and categories that are on the cutting edge of regenerative medicine research, stem cells are becoming increasingly relevant as the "runner-up" category to "neuroscience" related articles. The high volume of stem cell research casts a bright light on the hope for stem cells and their role in regenerative medicine as a number of reports deal with research using stem cells entering, or seeking approval for, clinical trials. The "methods and new technologies" and "tissue engineering" sections were almost equally as popular, and in part, reflect attempts to maximize the potential of stem cells and other treatments for the repair of damaged tissue. Transplantation studies were again more popular than non-transplantation, and the contribution of stem cell-related transplants was greater than other types of transplants. The non-transplantation articles were predominantly related to new methods for the preparation, isolation and manipulation of materials for transplant by specific culture media, gene therapy, medicines, dietary supplements, and co-culturing with other cells and further elucidation of disease mechanisms. A sizeable proportion of the transplantation articles reported on how previously new methods may have aided the ability of the cells or tissue to exert beneficial effects following transplantation.
