that would supply the tissue, the proper technology for dissecting, handling, storing, and administering the cells, and the right kind of drugs to give the patients to prevent the transplanted tissue from being rejected. The researchers performed brain scans, using advanced technology, to measure dopamine function in the brains of their volunteers before and after the transplants. And they carried out rigorous neurological testing of their volunteers for months before and after the transplants, so that any benefit or harm of the transplants could be assessed. All of this was overseen by university committees composed of doctors, administrators, and ethicists, whose role was to ensure that the volunteers were not exposed to undue risk, and that they were fully aware of those risks that could not be avoided. How was Iacono to replicate all of this, virtually by himself, and without any funds to support the project?
Iacono was based at a major medical centre – the University of Arizona Health Sciences Center in Tucson – but he would not have been allowed to do the transplant there, for two reasons. First, the operation was outside his recognised area of expertise. (‘I just don’t do stuff like that,’ was how he put it.) Second, there was a general ban on medical research using human foetal tissue at the University of Arizona – a state school in a very conservative state.
Iacono thought that the best way to overcome these difficulties was to do the operation overseas. He first thought of Japan, which he visited from time to time. But his Japanese colleagues were reluctant to get involved. Then, while in Japan, he met a doctor who worked in a cancer hospital in Zhengzhou, the capital of Henan province in China. The doctor suggested Iacono perform the transplant there: tissue from aborted foetuses was readily available, he said, and regulatory control was lax. ‘It’s no muss, no fuss in China,’ as Iacono put it.
Travelling halfway around the world for a surgical operation is not unheard of. Plenty of people fly from faraway places to have a procedure that is not available in their home countries. Still, what Iacono was proposing to do was very different: rather than take Truex to an established centre of excellence where the local doctors were experienced in the transplant procedure, he was planning to take him to what, in many people’s minds, could be considered the ‘back of beyond’, and more specifically to a hospital whose staff had absolutely no experience in this kind of surgery. Iacono was going to have to do almost everything himself, so if he was to succeed, he needed to be fully prepared.
Iacono did in fact prepare himself as best he could. ‘I was learning about immunosuppression, I studied up on the embryology, I read all the papers, and I developed my own technique – I solved millions of problems,’ he said. Still, he did not perform foetal-cell transplantations in animals as the other researchers had done, nor did he go and witness human foetal-cell transplant surgeries at one of the centres that were already doing them.
One problem stood out as the most challenging. The transplantation procedure involved stereotaxic surgery – that is, the use of a calibrated metal frame attached rigidly to the patient’s skull. By mounting the injection needle on the frame at a specified location and angle, it could be driven into the brain a predetermined distance and the surgeon would know that the tip was in the desired target, the striatum. Iacono was familiar with the techniques of stereotaxic surgery, but such surgery couldn’t be carried out at the Zhengzhou hospital – they simply didn’t have the facilities.
Iacono thought up a fairly devious scheme to get around this difficulty. In April of 1989, he operated on Truex at the Veterans Administration hospital in Tucson. The operation was a ‘thalamotomy’ – the destruction of part of a brain region called the thalamus. This is a
