<p>The present study investigated the effect of 4[(5,6,7,8-tetrahydro-5,5,8,8, -tetramethyl-2-naphthalenyl)car-bamoyl] benzoic acid (Am-80), a synthetic retinoid, on spinal cord injury (SCI) in rats. Treatment with Am-80 (orally and subcutaneously) significantly promoted recovery from SCI-induced motor dysfunction. On day 28 after injury, the lesion cavity was markedly reduced, while the expression of myelin basic protein (MBP; myelin), βIIItubulin (neuron), and glial fibrillary acidic protein (GFAP; astrocyte) was increased, in comparison with SCI controls. Interestingly, expression of neurotrophin receptor, tyrosine kinase B (TrkB) was over 3-fold higher after Am-80 treatment than in SCI controls. A lot of TrkB-positive cells as well as brain-derived neurotrophic factor (BDNF)-positive ones were observed around the injured site. Am-80 (10 μm) combined with BDNF (100ng/ml) promoted extensive neurite outgrowth and TrkB gene expression by cultured SH-SY5Y cells, as did all-trans retinoic acid (ATRA). Thymidine incorporation was dramatically suppressed, but there was little effect on cell viability. These findings suggest that Am-80 has the potential to be used for treating neurodegenerative disorders, including SCI. Its efficacy may be partly ascribed to promotion of cell viability and differentiation of neural stem cells through increased TrkB expression. © 2009 Pharmaceutical Society of Japan.</p>

<p>Induced pluripotent stem (iPS) cells are pluripotent stem cells directly reprogrammed from cultured mouse fibroblast by introducing Oct3/4, Sox2, c-Myc, and Klf4. Cells obtained using this technology, which allows the ethical issues and immunological rejection associated with embryonic stem (ES) cells to be avoided, might be a clinically useful source for cell replacement therapies. We found that secondary neurospheres (SNSs) generated from various mouse iPS cell showed their neural differentiation capacity and teratoma formation after transplantation into the brain of immunodeficient NOD/SCID mice. We found that origin (source of somatic cells) of the iPS cells are the crucial determinant for the potential tumorigenicity of iPS-derived neural stem/progenitor cells and that their tumorigenicity results from the persistent presence of undifferentiated cells within the SNSs. Surprisingly, SNSs derived from c-Myc minusiPS cells generated without drug selection showed robust tumorigenesis, in spite of their potential to contribute adult chimeric mice without tumor formation. Furthermore, we examined whether the transplantation of non-tumorigenic Nanog-iPS-derived SNSs into mouse spinal cord injury (SCI) model could promote locomotor function recovery. As a result, we found that properly pre-evaluated iPS clone-derived neural stem/progenitor cells may be a promising cell source for future transplantation therapy of SCI.</p>
