There is a reason that what is done in the laboratory is called research.  This finding in no way diminishes the potential of induced pluripotent stem cells {iPS).  It merely underscores the fact  that all forms of stem cell research must be pursued.  There are no easy or quick answers.

“Hopes for treating life-threatening diseases with cells taken from patients’ own bodies have suffered a setback after research showed they might trigger severe immune reactions.

The surprise finding will be a hurdle for scientists working on induced pluripotent stem (iPS) cells, a variety of cell that holds promise for treating conditions as diverse as muscular dystrophy, Parkinson’s and heart disease.“  Read More
