Abstract

SERRANO SANCHEZ, Dra. Teresa et al. Establishment of the conditions for the bone marrow cells transplants in a model of Huntington´s disease and functional effect on the motor behavior. Rev. colomb. biotecnol [online]. 2011, vol.13, n.2, pp.107-126. ISSN 0123-3475.

Huntington Disease (HD) is a heritable neurodegenerative disease that affects people with genetic history. Until today, an effective treatment doesn't exist; the illness advances slowly and the patient finishes in inability or death after 15 or 20 years. The studies related with the treatment of the clinical manifestations, include treatments with medications and the use of cells transplant. At the present time it is known that it is possible to reproduce, some characteristics of the disease in experimental models for to use possible therapies [example: estriatal lesion of quinolínico acid; (QA)]. the restorative effect of the bone marrow cells (BMC) is not known in this model. Objectives. 1) characterizationmorphofological of the estriatal lesion whith QA. 2) to characterization immunochemical of BMC. 3) to evaluate the BMC concentration for the transplant and 4) to evaluate the functional state of BMC transplant, through the motor behavior. Results. Establishment of the QA dose for to injure the striatum in appropriate way, immunophenotype of BMC was characterized, the good cellular concentration for the BMC transplant was established and was carried out the functional evaluation of the transplant. Conclusions. 1) the dose of 1.2 µL of QA, was able to injure appropriately of striatum, with a smaller affectation of structures striatum outside. 2) the BMC was positive for the markers CD34, CD38, CD45 and CD90, suggesting that this population is heterogeneous. 3) the best BMC concentration for the transplant was that of 100 000 cel / l, with the best survival and cellular migration. 4) we demonstrated an improvement in the motor behavior in the animals with BMC transplanted. This result suggests the importance of the BMC in the recovered of the lost functions and their importance to evaluate it as proceeding therapeutic in the HD.
