Chimeric brain: theoretical and clinical aspects.

???displayArticle.abstract???
Using xeno-transplantation, interactions of neural tissues of vertebrates and insects were studied. Ventral neurogenic primordium of Notch Drosophila melanogaster embryos was transplanted into neural tube of amphibian and mammalian embryos with the aid of microhydrofeeding. Embryos of four different amphibian species, random bred mice and rats were used as graft recipients. It was concluded that there is a possibility to incorporate nerve cells of insects into the brain of vertebrates. Morphological and functional contacts can be established between the transplanted cells and host brain tissues. Transplanted Drosophila cells preserve their viability for a long time, so that a prolonged influence of the transplant upon the recipient can be predicted, which may be used in medical practice. A mixture of human fetal brain and Notch Drosophila melanogaster neural embryonic tissues were transplanted into the ventro-lateral nucleus of the thalamus of the patients of Parkinson' disease. As a result, tremor and constrained movements disappeared. Post-operation patients have been observed within 13-38 months. No side effects were noted during this time.
