| Resumen en inglés | to offer HLA compatible grafts to a large population, the bank should offer a selection of cell supplies representative of all HLA types in the population, a virtually impossible task. Second, with HLA compatible grafts there remains a risk of immunorejection, and a necessity for the patients treated to take immunosuppressant drugs for the rest of their lives. Should biological research establish their feasibility and safety, cloning techniques might then appear to be the best choice. Treating (for example) diabetic patients with cells constructed by transferring the nucleus of a somatic cell of the patient into an enucleated oocyte would have the double advantage that the graft would be immunocompatible with the receiver, and that cell banks would not be required; instrumentalizing women for the collection of oocytes has been found objectionable, but a Chinese group of researchers suggested the possibility of using animal oocytes. It remains that such practices have raised lots of ethical controversies. It is at this moment difficult to assess their impact on our vision of 'humanity' |
