When Dr. Taylor paints her vision of the future, she emphasizes "we would take *your* stem cells and implant them." But when she talks about her own work, she talks about taking the stem cells of "a fertilized egg." She rhapsodizes about the billion stem cells in each of us, but her sympathy with present suffering (including her own experiences) drives her to take her stem cells wherever she can find them.

How much more inspiring it would be, if Dr. Taylor allowed her compassion for the suffering to drive her research into collecting and refining these precious stem cells in a way and from a source that does not raise ethical questions, questions with which even she herself seems not quite comfortable.
