Improving the effects of human adipose tissue-derived mesenchymal stem cells (ASCs) on the demyelination and neurobehavioral function was investigated in an experimental model of neonatal hypoxic-ischemic encephalopathy (HIE). Seven-day-old male rats were subjected to hypoxia-ischemia-lipopolysaccharide and intracerebroventricularly transplanted with human ASCs (4 × 105 cells/rat) once at postnatal day 10 (PND10) or repeatedly at PND10, 17, 27, and 37. Neurobehavioral abnormalities (at PND20, 30, and 40) and cognitive functions (at PND41‐44) were evaluated using multiple test systems. Human ASCs recovered the using ratio of forelimb contralateral to the injured brain, improved locomotor activity, and restored rota-rod performance of HIE animals, in addition to showing a marked improvement of cognitive functions. It was confirmed that transplanted human ASCs migrated to injured areas and differentiated into oligodendrocytes expressing myelin basic protein (MBP). Moreover, transplanted ASCs restored production of growth and neurotrophic factors and expression of decreased inflammatory cytokines, leading to attenuation of host MBP loss. The results indicate that transplanted ASCs restored neurobehavioral functions by producing MBP as well as by preserving host myelins, which might be mediated by ASCs’ anti-inflammatory activity and release of growth and neurotrophic factors.

More about this publication?
  • The importance of translating original, peer-reviewed research and review articles on the subject of cell therapy and its application to human diseases to society has led to the formation of the journal Cell Medicine. To ensure high-quality contributions from all areas of transplantation, the same rigorous peer review will be applied to articles published in Cell Medicine. Articles may 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, and stem cells, among others. Basic clinical studies and immunological research papers may also be featured if they have a translational interest. To provide complete coverage of this revolutionary field, Cell Medicine will report on relevant technological advances and their potential for translational medicine. Cell Medicine will be a purely online Open Access journal. There will therefore be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow your work to be disseminated to a wider audience and also entitle you to a free PDF, as well as prepublication of an unedited version of your manuscript.

    Cell Medicine is now being published by SAGE. Please visit their website for the most recent issues.
