Abstract
The regeneration of nerve tissue after spinal cord injury is a complex and poorly understood process. Medication and surgery are not very effective treatments for patients with spinal cord injuries. Gene therapy is a popular approach for the treatment of such patients. The delivery of therapeutic genes is carried out in a variety of ways, such as direct injection of therapeutic vectors at the site of injury, retrograde delivery of vectors, and ex vivo therapy using various cells. Recombinant adenoviruses are often used as vectors for gene transfer. This review discusses the advantages, limitations and prospects of adenovectors in spinal cord injury therapy.

Abstract
Spinal cord injury (SCI) is a central nervous system (CNS) devastate event that is commonly caused by traumatic or non-traumatic events. The reinnervation of spinal cord axons is hampered through a myriad of devices counting on the damaged myelin, inflammation, glial scar, and defective inhibitory molecules. Unfortunately, an effective treatment to completely repair SCI and improve functional recovery has not been found. In this regard, strategies such as using cells, biomaterials, biomolecules, and drugs have been reported to be effective for SCI recovery. Furthermore, recent advances in combinatorial treatments, which address various aspects of SCI pathophysiology, provide optimistic outcomes for spinal cord regeneration. According to the global importance of SCI, the goal of this article review is to provide an overview of the pathophysiology of SCI, with an emphasis on the latest modes of intervention and current advanced approaches for the treatment of SCI, in conjunction with an assessment of combinatorial approaches in preclinical and clinical trials. So, this article can give scientists and clinicians' clues to help them better understand how to construct preclinical and clinical studies that could lead to a breakthrough in spinal cord regeneration.

Abstract
Bone marrow stromal cells (BMSCs) are attractive cellular sources for cell therapy of many diseases, specifically neurodegenerative ones. The potential capability of BMSCs could be further augmented by enhancing their neuroprotective property, differentiation potential, and survival rate subsequent to transplantation. Therefore, a concurrent upregulation of neurotrophin-3 (NT-3) and its high affinity receptor, tyrosin kinase C (TrkC), was utilized in our study. BMSCs were cotransfected with pDsRed1-N1-NT-3 and pCMX-TrkC plasmids before induction of neural differentiation. pEGFP-N1-transfected BMSCs were also employed as a control. Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was employed for gene expression analysis. Cell viability was evaluated by MTT assay, while apoptosis rate was assessed by flow cytometry after PI and Annexin V staining. NT-3 and TrkC mRNA levels were greatly elevated following cotransfection of cells with pDsRed1-N1-NT-3 and pCMX-TrkC vectors. The expression of neural markers (i.e., NFM, and NeuroD1) was augmented in cotransfected BMSCs, compared to the control ones, after neural induction. At each time point, the viability and apoptosis rates of the cells over-expressing NT-3 and TrkC showed increased and reduced patterns, respectively. Our data demonstrated that NT-3/TrkC-co-transfected BMSCs, compared to those of intact cells, could be more beneficial graft candidates for the upcoming treatment strategies of neurogenic disorders due to their increased viability and expression of neural markers. This may be due to their increased level of neural differentiation potential and/or their enhanced rate of survival and/or their useful capacity to secrete NT-3.

Abstract
An investigation was conducted to demonstrate that neurodazine (Nz) and neurodazole (Nzl), two imidazole-based small molecules, promote neuronal differentiation in both neuroblastoma and fibroblast cells. The results show that differentiated cells generated by treatment with Nz and Nzl express neuron-specific markers. The ability of Nz and Nzl to induce neurogenesis of neuroblastoma and fibroblast cells was found to be comparable to those of the known neurogenic factors, retinoic acid and trichostatin A. In addition, the cells differentiated by Nz and Nzl are observed to express different isoforms of glutamate receptors. The results of signaling pathway studies reveal that two substances enhance neurogenesis in neuroblastoma cells by activating Wnt and Shh signaling pathways and neurogenesis in fibroblast cells by mainly activating the Wnt signaling pathway. Observations made in the present study suggest that Nz and Nzl will serve as chemical tools to generate specific populations of neuronal cells from readily available and simply manageable cells.

Abstract
In a previous study, we established a prenatal surgical approach and transplanted mesenchymal stem cells (MSCs) into the fetal rat spinal column to treat neural tube defects (NTDs). We found that the transplanted MSCs survived and differentiated into neural lineage cells. Various cytokines and extracellular signaling systems in the spinal cord niche play an important role in cell differentiation. In this study, we observed the differentiation of transplanted MSCs in different spinal cord niches and further observed the expression of neurotrophic factors and growth factors in the spinal cord at different developmental stages to explore the mechanism of MSC differentiation in different spinal cord niches. The results showed that transplanted MSCs expressed markers of neural precursor cells (nestin), neurogliocytes (GFAP), and neurons (β-tubulin). The percentages of GFP(+)/nestin(+) double-positive cells in transplanted MSCs in E16, P1, and P21 rats were 18.31%, 12.18%, and 5.06%, respectively. The percentages of GFP(+)/GFAP(+) double-positive cells in E16, P1, and P21 rats were 32.01%, 15.35%, and 12.56%, respectively. The percentages of GFP(+)/β-tubulin(+) double-positive cells in E16, P1, and P21 were 11.76%, 7.62%, and 4.88%, respectively. The differentiation rates of MSCs in embryonic spinal cords were significantly higher than in postnatal spinal cords (p < 0.05). We found that the transplanted MSCs expressed synapsin-1 at different developmental stages. After MSC transplantation, we observed that neurotrophic factor-3 (NT-3), fibroblast growth factor-2 (FGF-2), FGF-8, transforming growth factor-α (TGF-α), vascular endothelial growth factor (VEGF), and platelet-derived growth factor (PDGF) significantly increased in the MSC transplantation group compared with the blank injection group. Furthermore, FGF-2 and VEGF expression were positively correlated with the number of surviving MSCs. In addition, we found that the expression of brain-derived neurotrophic factor (BDNF), NT-3, FGF-8, TGF-β, epidermal growth factor (EGF), and insulin-like growth factor (IGF) decreased with age, and the expression of FGF-2, FGF-10, FGF-20, TGF-α, and PDGF increased with age. Our data suggest that the embryonic spinal cord niche is more conducive to MSC differentiation after transplantation.

Abstract
Salidroside (p-hydroxyphenethyl-β-D-glucoside, SAL), a phenylpropanoid glycoside isolated from a popular traditional Chinese medicinal plant Rhodiola rosea L., possesses multiple pharmacological actions. Previous study showed that SAL could induce rat mesenchymal stem cells (MSCs) to differentiate into dopaminergic neurons and induce mouse MSCs D1 to differentiate into neuronal cells. However, the mechanisms of SAL-induced neuronal differentiation of MSCs still need investigation. In this study, we observed the effects of SAL on neuronal differentiation of D1 cells and the possible involvement of Notch and BMP signaling pathways. SAL inhibited the proliferation, induced neuronal phenotypes, and upregulated the expressions of neuronal-specific marker molecules, such as neuronal enolase 2 (Eno2/NSE), microtubule-associated protein 2 (MAP2), and beta 3 class III tubulin (Tubb3/β-tubulin III) in D1 cells. SAL not only downregulated the expressions of Notch1 and hairy enhancer of split 1 (Drosophila) (Hes1) but also upregulated the expression of Smad1/5/8 and its phosphorylation (p-Smad 1/5/8). The neuronal differentiation effects of SAL on D1 cells were promoted by a Notch signaling antagonist, DAPT, but attenuated by a BMP signaling pathway antagonist, Noggin. Our findings suggest that SAL might be promising in inducing neuronal differentiation of mouse MSCs mediated by both Notch signaling pathway and BMP signaling pathway.

Abstract
Transplantation of bone marrow mesenchymal stem cells (MSCs) promotes functional recovery in multiple sclerosis (MS) patients and in a murine model of MS. However, there is only a modicum of information on differentiation of grafted MSCs into oligodendrocyte-like cells in MS. The purpose of this study was to transplant neurotrophin-3 (NT-3) and retinoic acid (RA) preinduced MSCs (NR-MSCs) into a demyelinated spinal cord induced by ethidium bromide and to investigate whether EA treatment could promote NT-3 secretion in the demyelinated spinal cord. We also sought to determine whether increased NT-3 could further enhance NR-MSCs overexpressing the tyrosine receptor kinase C (TrkC) to differentiate into more oligodendrocyte-like cells, resulting in increased remyelination and nerve conduction in the spinal cord. Our results showed that NT-3 and RA increased transcription of TrkC mRNA in cultured MSCs. EA increased NT-3 levels and promoted differentiation of oligodendrocyte-like cells from grafted NR-MSCs in the demyelinated spinal cord. There was evidence of myelin formation by grafted NR-MSCs. In addition, NR-MSC transplantation combined with EA treatment (the NR-MSCs + EA group) reduced demyelination and promoted remyelination. Furthermore, the conduction of cortical motor-evoked potentials has improved compared to controls. Together, our data suggest that preinduced MSC transplantation combined with EA treatment not only increased MSC differentiation into oligodendrocyte-like cells forming myelin sheaths, but also promoted remyelination and functional improvement of nerve conduction in the demyelinated spinal cord.

Abstract
Guided neuronal differentiation of induced pluripotent stem cells (iPSCs) with genetic regulation is an important issue in biomedical research and in clinical practice for nervous regeneration and repair. To enhance the intracellular delivery of plasmid DNA (pDNA), polybutylcyanoacrylate (PBCA) nanoparticles (NPs) were employed to mediate the transport of neurotrophin-3 (NT-3) into iPSCs. The ability of iPSCs to differentiate into neuronal lineages was shown by immunofluorescent staining, western blotting, and flow cytometry. By transmission electron microscopy, we found that PBCA NPs could efficiently grasp pDNA, thereby increasing the particle size and conferring a negative surface charge. In addition, the treatments with PBCA NP/NT-3 complexes enhanced the expression of NT-3, TrkC, NH-H, NSE, and PSD95 by differentiating iPSCs. Neurons produced from iPSCs were incapable of returning to pluripotency, demonstrating with a series of differentiation scheme for adipogenesis and osteogenesis. The pretreatment with PBCA NP/NT-3 complexes can be one of critical biotechnologies and effective delivery systems in gene transfection to accelerate the differentiation of iPSCs into neurons.

Abstract
Our previous study indicated that electroacupuncture (EA) could increase neurotrophin-3 (NT-3) levels in the injured spinal cord, stimulate the differentiation of transplanted bone marrow mesenchymal stem cells (MSCs), and improve functional recovery in the injured spinal cord of rats. However, the number of neuron-like cells derived from the MSCs is limited. It is known that NT-3 promotes the survival and differentiation of neurons by preferentially binding to its receptor TrkC. In this study, we attempted to transplant TrkC gene-modified MSCs (TrkC-MSCs) into the spinal cord with transection to investigate whether EA treatment could promote NT-3 secretion in the injured spinal cord and to determine whether increased NT-3 could further enhance transplanted MSCs overexpressing TrkC to differentiate into neuron-like cells, resulting in increased axonal regeneration and functional improvement in the injured spinal cord. Our results showed that EA increased NT-3 levels; furthermore, it promoted neuron-phenotype differentiation, synaptogenesis, and myelin formation of transplanted TrkC-MSCs. In addition, TrkC-MSC transplantation combined with EA (the TrkC-MSCs + EA group) treatment promoted the growth of the descending BDA-labeled corticospinal tracts (CSTs) and 5-HT-positive axonal regeneration across the lesion site into the caudal cord. In addition, the conduction of cortical motor-evoked potentials (MEPs) and hindlimb locomotor function increased as compared to controls (treated with the LacZ-MSCs, TrkC-MSCs, and LacZ-MSCs + EA groups). In the TrkC-MSCs + EA group, the injured spinal cord also showed upregulated expression of the proneurogenic factors laminin and GAP-43 and downregulated GFAP and chondroitin sulfate proteoglycans (CSPGs), major inhibitors of axonal growth. Together, our data suggest that TrkC-MSC transplantation combined with EA treatment spinal cord injury not only increased MSC survival and differentiation into neuron-like cells but also promoted CST regeneration across injured sites to the caudal cord and functional improvement, perhaps due to increase of NT-3 levels, upregulation of laminin and GAP-43, and downregulation of GFAP and CSPG proteins.

Abstract
Implantation of marrow-derived mesenchymal stem cells (MSCs) is the most promising therapeutic strategy for the treatment of spinal cord injury (SCI), especially because of their potential for clinical application, such as the avoidance of immunologic rejection, their strong secretory properties, and their plasticity for developing into neural cells. However, the recovery from SCI after MSC implantation is minimal due to their limited capacity for the reduction of cystic cavitation, for the axonal regeneration and their uncertain neural plasticity in the spinal cord. We previously pretreated MSCs with all-trans retinoic acid (RA) in vitro. Then we genetically modified them to overexpress neurotrophin-3 (NT-3) via a recombinant adenoviral vector (Adv). This combined treatment not only permitted more neuronal differentiation of MSCs, but stimulated more NT-3 secretion prior to grafting, according to our previous and present results. When these cells were implanted into the transected spinal cord of rats, the animals had some improvement (both functionally and structurally), including the recovery of hindlimb locomotor function, shown by the highest Basso, Beattie, and Bresnahan (BBB) scores, as well as dramatically reduced cavity volume, clear axonal regeneration and more neuronal survival. In contrast, simple MSC implantation is not a very effective therapy for spinal transection. However, the neuronal differentiation of MSCs after treatment with a combination of Adv-mediated NT-3 gene transfer and RA was only mildly improved in vivo.

Abstract
In order to improve the structure and function of acute spinal cord injury, the present study investigated the effect of electro-acupuncture (EA) on the differentiation of mesenchymal stem cells (MSCs) and the regeneration of nerve fibers in transected spinal cord of rats. The differentiation of MSCs into neuron-like cells and neuroglial cells and regeneraton of 5-hydroxytrptamine (HT) nerve fibers in the injured site of spinal cord were assessed after treatment with EA, MSCs transplantation, and EA plus MSCs transplantation. Compared with the control and MSCs groups, the content of endogenous neurotrophin-3 (NT-3) in the injured site and nearby tissues was increased in EA and EA+MSCs group. The differentiation of MSCs into neuronal-like cells and oligodendrocyte-like cells and number of 5-HT positive nerve fibers in the injured site were enhanced in the EA+MSCs group. Basso, Beattie, Bresnahan score of the paralyzed hindlimbs was highest in the EA+MSCs group. The present study demonstrates that electro-acupuncture can promote the differentiation of MSCs and regeneration of nerve fibers in injured spinal cord through induction of endogenous NT-3, and that combination of EA and MSCs transplantation can improve partial function of paralyzed hindlimbs.

Transfection efficiencies of PAMAM dendrimers correlate inversely with their hydrophobicity. Int J Pharm 2009; 383:228-35.

Abstract
Dendriplexes were characterized by ethidium bromide intercalation assay and their transfection efficiency was studied using HEK 293 cells and human mesenchymal stem cells. PAMAM G4 showed a higher transfection efficiency than PAMAM G3-G6, G4-OH, G4-25% or G4-50% dendrimers. Substitution of OH groups for the NH(2) surface groups rendered the dendrimer unable to form dendriplexes and to transfect cells. Partial (25%) substitution of CH(3) groups for the NH(2) groups markedly impaired transfection; 50% substitution decreased the ability of PAMAM G4 to transfect threefold. It was concluded that increased hydrophobicity decreased the ability of dendrimers to transfect. PAMAM G4-50% is highly hydrophobic and forms micelles in solution, which can transfect pGFP. The results of ethidium bromide intercalation assays, ANS fluorescence studies and transfection efficiencies of PAMAM dendrimers were correlated. Subsequently, we constructed a neurotrophin-encoding plasmid and studied its delivery to mesenchymal stem cells using PAMAM G4 dendrimer and Lipofectamine 2000. Lipofectamine 2000 was a more effective carrier (18.5%) than PAMAM G4 dendrimer (1.2%).

Abstract
This study investigates the physicochemical properties of poly(lactide-co-glycolide) (PLGA)/chitosan scaffolds and the neuron growth factor (NGF)-guided differentiation of bone marrow stromal cells (BMSCs) in the scaffolds. The scaffolds were prepared by the crosslinking of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, N-hydroxysuccinimide and genipin, and the differentiating BMSCs were characterized against CD44, CD90 and NeuN. The scaffold with 20% PLGA yielded 95% porosity, Young's modulus of 13MPa, 70% adhesion of BMSCs and 1.6-fold increase in the cell viability over 7-day cultivation. BMSCs without guidance in the PLGA/chitosan scaffolds were prone to differentiate toward osteoblasts with apparent deposition of calcium. When NGF was introduced, an increased weight percentage of PLGA yielded more identified neurons. In addition, mature neurons emerged from the PLGA-rich biomaterials after induction with NGF over 2 days. A proper control over the physical and biomedical property of the scaffolds and the NGF-guided differentiation of BMSCs can be promising for nerve regeneration.

Abstract
We report the use of polyamidoamine (PAMAM-NH(2)) dendrimers along with other non-viral vehicles for the in vitro transfection of human bone marrow mesenchymal stem cells (hMSCs) and for engineering MSCs to secrete brain-derived neurotrophic factor (BDNF). Different generations of cationic polyamidoamine dendrimers (generations 3-6) were tested on HEK 293T cells. hMSCs were then transfected with PAMAM-NH(2) G4 dendrimers and Lipofectamine 2000, which elicited the expression of GFP reporter in around 6 and 20% of the cells, respectively. Both vehicles were then shown to elicit the expression of BDNF in MSCs from a bicistronic cassette. Non-virally induced neurotrophin expression may be a safe and easy method for adapting autologous stem cells for therapeutic treatment of diseases and neural system injuries.

Abstract
Human mesenchymal stem cells (MSCs) reside in the bone marrow and are known for their ability to differentiate along the mesenchymal lineage (fat, bone, and cartilage). Recent works have suggested the possibility that these cells are also capable of differentiating toward the neuroectodermal lineage. Using lentiviral gene delivery, we sought to reprogram the bone marrow-derived MSCs toward dopaminergic differentiation through delivery of LMX1a, which was reported to be a key player in dopaminergic differentiation in both developmental animal models and embryonic stem cells. Transduction of cells with fluorescent reporter genes confirmed efficiency of gene delivery. On incubation of the LMX1a transduced cells in differentiation medium, the LMX1a protein was concentrated in the cells' nuclei and specific dopaminergic developmental genes were upregulated. Moreover, the transduced cells expressed higher levels of tyrosine hydroxylase, the rate limiting enzyme in dopamine synthesis, and secreted significantly higher level of dopamine in comparison to nontransduced cells. We hereby present a novel strategy to facilitate the dopaminergic differentiation of bone marrow-derived MSCs as a possible cell source for autologous transplantation for Parkinsonian patients in the future.

Abstract
Background Bone marrow mesenchymal stem cells (MSCs) are one of the potential tools for treatment of the spinal cord injury; however, the survival and differentiation of MSCs in an injured spinal cord still need to be improved. In the present study, we investigated whether Governor Vessel electro-acupuncture (EA) could efficiently promote bone marrow mesenchymal stem cells (MSCs) survival and differentiation, axonal regeneration and finally, functional recovery in the transected spinal cord. Results The spinal cords of adult Sprague-Dawley (SD) rats were completely transected at T10, five experimental groups were performed: 1. sham operated control (Sham-control); 2. operated control (Op-control); 3. electro-acupuncture treatment (EA); 4. MSCs transplantation (MSCs); and 5. MSCs transplantation combined with electro-acupuncture (MSCs+EA). After 2-8 weeks of MSCs transplantation plus EA treatment, we found that the neurotrophin-3 (NT-3), cAMP level, the differentiation of MSCs, the 5-HT positive and CGRP positive nerve fibers in the lesion site and nearby tissue of injured spinal cord were significantly increased in the MSCs+EA group as compared to the group of the MSCs transplantation or the EA treated alone. Furthermore, behavioral test and spinal cord evoked potentials detection demonstrated a significantly functional recovery in the MSCs +EA group. Conclusion These results suggest that EA treatment may promote grafted MSCs survival and differentiation; MSCs transplantation combined with EA treatment could promote axonal regeneration and partial locomotor functional recovery in the transected spinal cord in rats and indicate a promising avenue of treatment of spinal cord injury.

Abstract
Skin-derived precursors (SKPs) are derived from mesoblast and can differentiate into smooth muscle cells, adipocytes, and less neuronal phenotypes. This study demonstrates that retinoic acid (RA) improves SKPs exit from self-proliferation to neural differentiation through up-regulating of NeuroD and cell-cycle regulatory protein p21, meanwhile RA also induces p75 neurotrophin receptor (p75NTR) up-regulation and apoptosis of SKPs. When treated sequentially with neurotrophin-3 (NT-3) after RA induction, the survival and neural differentiation of SKPs were enhanced significantly, and cell apoptosis induced by RA was decreased. These effects could be reversed by p75NTR inhibitor Pep5 instead of Trk receptor inhibitor K252a. The results indicate that NT-3 improves the neural differentiation of SKPs induced by RA through a p75NTR-dependent signaling pathway.

Abstract
Human bone marrow-derived mesenchymal stem cells (BM-hMSCs) are nonhematopoietic stem cells that have the potential to differentiate into adipocytes, osteocytes and chondrocytes. Because of its propensity to migrate to the sites of injury and the ability to expand them rapidly, BM-hMSCs have been exploited as potential gene transfer vehicles to deliver therapeutic genes. Herein, we evaluated the feasibility of employing herpes simplex virus type I (HSV-1) amplicon viral vector as a gene delivery vector to BM-hMSCs. High transduction efficiencies were consistently observed in different isolates of BM-hMSCs following infection with HSV-1 amplicon viral vectors. Furthermore, we demonstrated that transduction with HSV-1 amplicon viral vector did not alter the intrinsic properties of the BM-hMSCs. The morphology and cellular proliferation of the transduced BM-hMSCs were not altered. Chromosomal stability, as confirmed by karyotyping and soft agar colony assays, of the transduced BM-hMSCs was not affected. Similarly, transduction with HSV-1 amplicon viral vectors has no effect on the pluripotent differentiation potential and the tumor tropism of BM-hMSCs. Taken together, these results demonstrated that BM-hMSCs could be transduced efficiently by HSV-1 amplicon viral vector in an 'inert' manner and thus enable strategies to express potential therapeutic genes in BM-hMSCs.
