| Abstract | Parkinson’s disease (PD) is a neurodegenerative disorder with its motor phenomena due mostly to loss of dopamine-producing neurons in the substantia nigra. Pharmacological treatments aimed to increase the deficient dopaminergic neurotransmission are effective in ameliorating the cardinal symptoms, but none of these therapies is curative. It has been suggested that treatment with neurotrophic factors (NTFs) might protect and prevent death of the surviving dopaminergic neurons and induce proliferation of their axonal nerve terminals with reinnervations of the deafferented striatum. However, long-term delivery of such proteins into the CNS is problematic. We therefore aimed to differentiate ex vivo human bone marrow-derived mesenchymal stromal cells into astrocyte-like cells, capable of generating NTFs for future transplantation into basal ganglia of PD patients. Indeed, mesenchymal stromal cells treated with our novel astrocyte differentiation medium, present astrocyte-like morphology and express the astrocyte markers S100β, glutamine synthetase and glial fibrillary acidic protein. Moreover, these astrocyte-like cells produce and secrete significant amounts of glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), and brain-derived neurotrophic factor as indicated by messenger RNA, real-time polymerase chain reaction, ELISA, and Western blot analyses. Such NTF-producing cells transplanted into the striatum of 6-hydroxydopamine-lesioned rats, a model of PD, produced a progressive reduction in the apomorphine-induced contralateral rotations as well as behavioral improvement in rotor-rod and the “sunflower seeds” eating motor tests. Histological assessments revealed that the engrafted cells survived and expressed astrocyte and human markers and acted to regenerate the damaged dopaminergic nerve terminal system. Findings indicate that our novel procedure to induce NTF-producing astrocyte-like cells derived from human bone marrow stromal cells might become a promising and feasible autologous transplantation strategy for PD. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
