Roadmap To Overcome Obstacles For Using Induced Pluripotent Stem Cells: The possibility of developing stem cells from a patient's own skin and using them to treat conditions as diverse as Parkinson's disease, Alzheimer's disease and cancer has generated tremendous excitement in the stem cell research community in recent years. Such therapies would avoid the controversial need for using stem cells derived from human embryos, and in theory, also bypass immunological problems inherent in using cells from one person to treat another.
However, in the nearly five years since the first article describing the development of stem cells derived from adult cells - so-called induced pluripotent stem cells (iPSCs) - unique problems inherent in their use have surfaced and even their immunological safety has been called into question.
