Cell Therapy From Bench to Bedside Translation in CNS Neurorestoratology Era
Abstract:Recent advances in cell biology, neural injury and repair, and the progress towards development of neurorestorative interventions are the basis for increased optimism. Based on the complexity of the processes of demyelination and remyelination, degeneration and regeneration, damage and repair, functional loss and recovery, it would be expected that effective therapeutic approaches will require a combination of strategies encompassing neuroplasticity, immunomodulation, neuroprotection, neurorepair, neuroreplacement, and neuromodulation. Cell-based restorative treatment has become a new trend, and increasing data worldwide have strongly proven that it has a pivotal therapeutic value in CNS disease. Moreover, functional neurorestoration has been achieved to a certain extent in the CNS clinically. Up to now, the cells successfully used in preclinical experiments and/or clinical trial/treatment include fetal/embryonic brain and spinal cord tissue, stem cells (embryonic stem cells, neural stem/progenitor cells, hematopoietic stem cells, adipose-derived adult stem/precursor cells, skin-derived precursor, induced pluripotent stem cells), glial cells (Schwann cells, oligodendrocyte, olfactory ensheathing cells, astrocytes, microglia, tanycytes), neuronal cells (various phenotypic neurons and Purkinje cells), mesenchymal stromal cells originating from bone marrow, umbilical cord, and umbilical cord blood, epithelial cells derived from the layer of retina and amnion, menstrual blood-derived stem cells, Sertoli cells, and active macrophages, etc. Proof-of-concept indicates that we have now entered a new era in neurorestoratology.

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.
