...places in which their discoveries were made, there is a sturdy thread of tangible traits that unites them all. Even during the past four decades, which have witnessed medical innovation on an unprecedented scale, that sturdy thread has not frayed. Nor has the rapidity of achievement--with the linear progress of yesterday succumbing to exponential acceleration--stretched it to the breaking point. If anything, the new science and its bedside applications have provided more evidence than ever before that certain tangible human characteristics inevitably accompany innovation...
...medical theory and practice are based on an ever expanding body of knowledge handed down from one generation to the next, it follows that progress will occur only when additions are made to that knowledge. Although this is true for the most part, every era sees a few marked departures from the acquired wisdom--departures somes so radical as to create entirely new ways of looking at the evidence gleaned from the study of nature and disease...
Fifteen years ago, Dr. Terry Ernest, an ophthalmologist, had to tell his own father the news that he so dreaded giving his patients: Your eyesight is progressively deteriorating, and there is no cure for the condition. Despite tremendous medical progress in treating many forms of vision loss, Ernest could do nothing but watch as his father's eyesight slowly faded, eventually robbing him of the pleasure of pursuing the pages of his favorite books or seeing the smile on his son's face.

...team made progress on one front, Ernest grew increasingly worried about the immune system's response to the transplants. Contrary to what many had supposed, fetal RPE cells did not behave as if they were immunologically neutral. In experiments in Sweden, for example, transplanted cells were rejected. And Ernest's team found that adding fetal RPE cells to laboratory cultures sent white blood cells, which attack transplanted tissue, into overdrive. Curiously, however, adding even greater numbers of RPE cells to the culture appeared to force the white blood cells into a quiescent state, thus lowering the chances of rejection. Pearl...
