The actual source and manufacturing of the stem cells in this case is of critical importance. The fact that there are multiple donors gives real concern in that there may have been contaminants such as viral particles. All researchers and companies have a scientific and moral requirement to fully disclose the source, expansion methods, media and delivery methods of any stem cells for animal or human research or clinical use so that we may all progress the field in a responsible manner. The lack of this information can unduely damage the reputation of the field and legitimate researchers. From this article, we have no way to validate or investigate the concern and determine if it is the cells, the media, or the infectious disease status and age of the donor(s).
