Abstract:

In order to deliver glial cell line-derived neurotrophic factor (GDNF) into the brain, we have established a cell line that produces GDNF in a continuous fashion by genetic engineering. These cells were encapsulated and grafted into parkinsonian model rats that had received unilateral intrastriatal injection of 6-hydroxydopamine 2 weeks earlier. Neurochemical analysis showed that GDNF has been produced from the capsule for 6 months after grafting and histological analysis revealed good survival of GDNF-producing cells in the capsule 6 months after grafting. The density of nigrostriatal dopaminergic fibers in the striatum as well as the number of dopaminergic cell bodies in the substantia nigra recovered significantly after GDNF-producing cell grafting. These results suggest the possible application of GDNF-producing cell grafting for the treatment of Parkinson's disease.

More about this publication?
  • Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
