JOURNAL/nrgr/04.03/01300535-202502000-00035/figure1/v/2024-05-28T214302Z/r/image-tiff Photobiomodulation, originally used red and near-infrared lasers, can alter cellular metabolism. It has been demonstrated that the visible spectrum at 451-540 nm does not necessarily increase cell proliferation, near-infrared light promotes adipose stem cell proliferation and affects adipose stem cell migration, which is necessary for the cells homing to the site of injury. In this in vitro study, we explored the potential of adipose-derived stem cells to differentiate into neurons for future translational regenerative treatments in neurodegenerative disorders and brain injuries. We investigated the effects of various biological and chemical inducers on trans-differentiation and evaluated the impact of photobiomodulation using 825 nm near-infrared and 525 nm green laser light at 5 J/cm2. As adipose-derived stem cells can be used in autologous grafting and photobiomodulation has been shown to have biostimulatory effects. Our findings reveal that adipose-derived stem cells can indeed trans-differentiate into neuronal cells when exposed to inducers, with pre-induced cells exhibiting higher rates of proliferation and trans-differentiation compared with the control group. Interestingly, green laser light stimulation led to notable morphological changes indicative of enhanced trans-differentiation, while near-infrared photobiomodulation notably increased the expression of neuronal markers. Through biochemical analysis and enzyme-linked immunosorbent assays, we observed marked improvements in viability, proliferation, membrane permeability, and mitochondrial membrane potential, as well as increased protein levels of neuron-specific enolase and ciliary neurotrophic factor. Overall, our results demonstrate the efficacy of photobiomodulation in enhancing the trans-differentiation ability of adipose-derived stem cells, offering promising prospects for their use in regenerative medicine for neurodegenerative disorders and brain injuries.

Abstract
Neonatal brain injury affects thousands of babies each year and may lead to long-term and permanent physical and neurological problems. Currently, therapeutic hypothermia is standard clinical care for term newborns with moderate to severe neonatal encephalopathy. Nevertheless, it is not completely protective, and additional strategies to restore and promote regeneration are urgently needed. One way to ensure recovery following injury to the immature brain is to augment endogenous regenerative pathways. However, novel strategies such as stem cell therapy, gene therapies and nanotechnology have not been adequately explored in this unique age group. In this perspective review, we describe current efforts that promote neuroprotection and potential targets that are unique to the developing brain, which can be leveraged to facilitate neuroregeneration.

Abstract
While biophysical stimuli from polymeric matrices are known to significantly affect the fates of human mesenchymal stem cells (hMSCs), the stimulatory effects of nano-sized silicon-based matrices on hMSCs have not been thoroughly investigated. We previously demonstrated that vertically aligned, single-crystalline silicon nanowires (SiNWs) can control the osteogenicity of hMSCs via controllable spring constants from SiNWs matrix. However, other possible differentiation fates of hMSCs on SiNWs have not been explored. We hypothesize that tunable spring constant from artificial SiNWs matrices can direct different types of hMSC differentiations. The spring constants of tunable SiNW matrices can be consistently controlled by tuning the SiNW length. The results of gene expression and cell stiffness suggest that hMSCs differentiations are sensitive to our distinguishable spring constants from the SiNWs groups, and simultaneously conduct osteogenicity and adipogenicity. These findings suggest that SiNW matrices can regulate the fates of hMSCs when the SiNW characteristics are carefully tuned.

Abstract
Stroke remains a major cause of human disability worldwide. In parallel with advances in acute stroke interventions, new therapies are under development that target restorative processes. Such therapies have a treatment time window measured in days, weeks, or longer and so have the advantage that they may be accessible by a majority of patients. Several categories of restorative therapy have been studied and are reviewed herein, including drugs, growth factors, monoclonal antibodies, activity-related therapies including telerehabilitation, and a host of devices such as those related to brain stimulation or robotics. Many patients with stroke do not receive acute stroke therapies or receive them and do not derive benefit, often surviving for years thereafter. Therapies based on neural repair hold the promise of providing additional treatment options to a majority of patients with stroke.

Abstract
Sustained and controlled release of neurotrophic factors in target tissue through nanomaterial based delivery system could be a better strategy for nerve tissue regeneration. The present study aims to prepare the nerve growth factor (NGF) encapsulated chitosan nanoparticles (NGF-CNPs) and its evaluation on neuronal differentiation potentiality of canine bone marrow derived mesenchymal stem cells (cBM-MSCs). The NGF-CNPs were prepared by ionotropic gelation method with tripolyphosphate (TPP) as an ionic cross-linking agent. Observations on physiochemical properties displayed the size of nanoparticles as 80-90 nm with positive zeta potential as well as an ionic interaction between NGF and nanoparticle. NGF loading efficiency was found to be 61% while its sustained release was observed by an in vitro release kinetics study. These nanoparticles were found to be cytocompatible to cBM-MSCs when supplemented at a concentration upto 4 mg/ml in culture media. The NGF-CNP supplemented culture media was able to transdifferentiate the preinduced cBM-MSCs into neurons in a better way than unbound NGF supplementation. Further, it was also noticed that NGF-CNPs were able to transdifferentiate cBM-MSCs without any chemical based preinduction. In conclusion, our findings propose that NGF-CNPs are capable of releasing bioactive NGF with the ability to transdifferentiate mesenchymal stem cells into neurons, suggesting its potential future application in nerve tissue regeneration.

Combined therapy involving electroacupuncture and treadmill exercise attenuates demyelination in the corpus callosum by stimulating oligodendrogenesis in a rat model of neonatal hypoxia-ischemia. Exp Neurol 2017; 300:222-231. [PMID: 29199131 DOI: 10.1016/j.expneurol.2017.11.014] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2017] [Revised: 11/09/2017] [Accepted: 11/29/2017] [Indexed: 01/09/2023]
Abstract
We investigated whether electroacupuncture (EA) and treadmill (TM) exercise improve behaviors related to motor and memory dysfunction in a cerebral palsy-like rat model via activation of oligodendrogenesis. A neonatal hypoxia-ischemia model was created using Sprague-Dawley rats (P7), and these underwent EA stimulation and treadmill training from 3 to 5weeks after hypoxia-ischemia induction. EA treatment was delivered via electrical stimulation (2Hz, 1mA) at two acupoints, Baihui (GV20) and Zusanli (ST36). Behavioral tests showed that EA alleviated motor dysfunction caused by hypoxia-ischemia on a rotarod test, and TM exercise alleviated motor and memory dysfunction seen on cylinder and passive avoidance tests. Combined therapy with EA and TM exercise showed synergistic effects on the cylinder, rotarod, and catwalk tests. TM exercise significantly restored corpus callosum thickness, and combined therapy with EA and TM restored myelin basic protein (MBP) levels in this region. While EA stimulation only increased activation of cAMP-response element binging protein (CREB) in oligodendrocytes of the corpus callosum, TM exercise increased newly generated oligodendrocyte progenitor cells or oligodendrocytes via activation of CREB. Synergistic effects on oligodendrogenesis were also observed by the combined therapy. Furthermore, the combined therapy induced mature brain-derived neurotrophic factor (BDNF) expression in the cerebral cortex. These results demonstrate that combined therapy with EA and TM exercise may restore myelin components following neonatal hypoxia-ischemia via upregulation of oligodendrogenesis involving CREB/BDNF signaling, which subsequently improves motor and memory function. Therefore, combined therapy with EA and TM exercise offers another treatment option for functional recovery from injuries caused by neonatal hypoxia-ischemia, such as cerebral palsy.

Abstract
Spinal cord injury (SCI) can cause severe traumatic injury to the central nervous system (CNS). Current therapeutic effects achieved for SCI in clinical medicine show that there is still a long way to go to reach the desired goal of full or significant functional recovery. In basic medical research, however, cell transplantation, gene therapy, application of cytokines, and biomaterial scaffolds have been widely used and investigated as treatments for SCI. All of these strategies when used separately would help rebuild, to some extent, the neural circuits in the lesion area of the spinal cord. In light of this, it is generally accepted that a combined treatment may be a more effective strategy. This review focuses primarily on our recent series of work on transplantation of Schwann cells and adult stem cells, and transplantation of stem cell-derived neural network scaffolds with functional synapses. Arising from this, an artificial neural network (an exogenous neuronal relay) has been designed and fabricated by us—a biomaterial scaffold implanted with Schwann cells modified by the neurotrophin-3 (NT-3) gene and adult stem cells modified with the TrkC (receptor of NT-3) gene. More importantly, experimental evidence suggests that the novel artificial network can integrate with the host tissue and serve as an exogenous neuronal relay for signal transfer and functional improvement of SCI.

Abstract
Neurotrophic factors are growth factors that can nourish neurons and promote neuron survival and regeneration. They have been studied as potential drug candidates for treating neurodegenerative diseases. Since their identification, there are more and more evidences to indicate that neurotrophic factors are also expressed in non-neuronal tissues and regulate the survival, anti-inflammation, proliferation and differentiation in these tissues. This mini review summarizes the characteristics of the neurotrophic factors and their potential clinical applications in the regeneration of neuronal and non-neuronal tissues.

Abstract
Bone marrow-derived mesenchymal stem cells can differentiate into a variety of adult cells. Brain-derived neurotrophic factor (BDNF) is briefly active during differentiation and induces mesenchymal stem cells to differentiate into nerve cells. In this study, we cloned human BDNF to generate a recombinant pcDNA3.1(-)-BDNF vector and transfected the vector into bone marrow-derived mesenchymal stem cells. We selected these cells with Geneticin-418 to obtain BDNF-BMSCs, which were induced with retinoic acid to obtain induced BDNF-BMSCs. The transfected cells displayed the typical morphology and surface antigen profile of fibroblasts and were observed to express clusters of differentiation 29, 44, and 90 (observed in matrix and stromal cells), but not clusters of differentiation 31, 34, and 45 (observed in red blood cells and endothelial cells), via flow cytometry. Enzyme-linked immunosorbent assays showed that transfected bone marrow-derived mesenchymal stem cells secreted more BDNF than non-transfected bone marrow-derived mesenchymal stem cells. Immunocytochemistry and real-time reverse transcription polymerase chain reaction analysis showed that non-induced BDNF-BMSCs maintained a higher proliferative capacity and expressed higher amounts of brain-derived neurotrophic factor, nestin, neuron-specific enolase, and glial fibrillary acid protein than non-transfected bone marrow-derived mesenchymal stem cells. An additional increase was observed in the induced BDNF-BMSCs compared to the non-induced BDNF-BMSCs. This expression profile is characteristic of neurocytes. Our data demonstrate that bone marrow-derived mesenchymal stem cells transfected with the BDNF gene can differentiate into nerve-like cells in vitro, which may enable the generation of sufficient quantities of nerve-like cells for treatment of neuronal diseases.

Abstract
Great challenges in transplantation of mesenchymal stem cells (MSCs) for treating ischemic diabetic ulcers (IDUs) are to find a suitable carrier and create a beneficial microenvironment. Brain-derived neurotrophic factor (BDNF), a member of neurotrophin family, is considered angiogenic and neuroprotective. Given that IDUs are caused by vascular disease and peripheral neuropathy, we used BDNF as a stimulant, and intended to explore the role of new biomaterials complex with MSCs in wound healing. BDNF promoted the proliferation and migration of MSCs using MTT, transwell, and cell scratch assays. The activity of human umbilical vein endothelial cells (HUVECs) was also enhanced by the MSC-conditioned medium in the presence of BDNF, via a vascular endothelial growth factor-independent pathway. Since proliferated HUVECs in the BDNF group made the microenvironment more conducive to endothelial differentiation of MSCs, by establishing co-culture systems with the two cell types, endothelial cells derived from MSCs increased significantly. A new biomaterial made of polylactic acid, silk and collagen was used as the carrier dressing. After transplantation of the BDNF-stimulated MSC/biomaterial complex, the ulcers in hindlimb ischemic mice healed prominently. More blood vessel formation was observed in the wound tissue, and more MSCs were co-stained with some endothelial-specific markers such as cluster of differentiation (CD)31 and von Willebrand Factor (vWF) in the treatment group than in the control group. These results demonstrated that BDNF could improve microenvironment in the new biomaterial, and induce MSCs to differentiate into endothelial cells indirectly, thus accelerating ischemic ulcer healing.

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
BACKGROUND Spinal cord has a limited capacity to repair; therefore, medical interventions are necessary for treatment of injuries. Transplantation of Schwann cells has shown a great promising result for spinal cord injury (SCI). However, harvesting Schwann cell has been limited due to donor morbidity and limited expansion capacity. Furthermore, accessible sources such as bone marrow stem cells have drawn attentions to themselves. Therefore, this study was designed to evaluate the effect of bone marrow-derived Schwann cell on functional recovery in adult rats after injury. METHODS Mesenchymal stem cells were cultured from adult rats' bone marrow and induced into Schwann cells in vitro. Differentiation was confirmed by immunocytochemistry and RT-PCR. Next, Schwann cells were seeded into collagen scaffolds and engrafted in 3 mm lateral hemisection defects. For 8 weeks, motor and sensory improvements were assessed by open field locomotor scale, narrow beam, and tail flick tests. Afterwards, lesioned spinal cord was evaluated by conventional histology and immunohistochemistry. RESULTS In vitro observations showed that differentiated cells had Schwann cell morphology and markers. In this study, we had four groups (n = 10 each): laminectomy, control, scaffold and scaffold + Schwann cells. Locomotor and sensory scores of cell grafted group were significantly better than control and scaffold groups. In histology, axonal regeneration and remyelination were better than control and scaffold groups. CONCLUSION This study demonstrates that bone marrow-derived Schwann cells can be considered as a cell source for Schwann cells in SCI treatment.

Abstract
This study is aimed to determine the effect of transplantation of neural progenitor cells (NPCs) isolated from fetal hippocampus on cognitive functions of experimental animals after short-term global cerebral ischemia. NPCs were isolated from hippocampus of FVB-Cg-Tg(GFPU)5Nagy/J mice, transgenic by the GFP. Ischemic brain injury in FVB “wild” type mice was modeled by bilateral occlusion of the common carotid arteries for 20 min. GFP-positive NPCs were stereotaxically transplanted into the hippocampus of experimental animals in 24 hours after ischemia-reperfusion. Cognitive functions were evaluated using Morris water maze. Results of this study showed that global short-term cerebral ischemia resulted into cognitive impairments in mice. Stereotaxic transplantation of NPCs promoted the cognitive function recovery in experimental animals after ischemic brain injury. Thus, the data indicates that transplantation of NPCs may have a therapeutic effect in treating of ischemic stroke.

Abstract
Introduction Stroke is a major cause of permanent neurologic damage, with few effective treatments available to restore lost function. Induced pluripotent stem cells (iPSCs) have the potential to generate all cell types in vitro and can be generated from a stroke patient. Therefore, iPSCs are attractive donor sources of genetically identical “patient-specific” cells to hold promise in therapy for stroke. In the present study, we established a four-stage culture system by using serum-free medium and retinoic acid (RA) to differentiate iPSCs into neural stem cells (NSCs) effectively and stably. Our hypothesis was that iPSC-derived NSCs would survive, migrate, and differentiate in vivo, and improve neurologic function after transplantation into the brains of rats with ischemic stroke. Methods Human iPSCs (iPS-S-01) and human ESCs (HuES17) were used to differentiate into NSCs by using our four-stage culture system. iPSCs and differentiated NSCs were characterized by immunocytochemistry staining and reverse transcription-polymerase chain reaction (RT-PCR) analysis. After establishment of focal cerebral ischemia with occlusion of the middle cerebral artery (MCA) and cell transplantation, animals were killed at 1 week and 2 weeks to analyze survival, migration, and differentiation of implanted cells in brain tissue. Animal behavior was evaluated via rope grabbing, beam walking, and Morris water maze tests. Results iPSCs were efficiently induced into NSCs by using a newly established four-stage induction system in vitro. iPSCs expressed pluripotency-associated genes Oct4, Sox2, and Nanog before NSC differentiation. The iPSC-derived NSCs spontaneously differentiated into neurons and astrocytes, which highly express β-tubulin and glial fibrillary acidic protein (GFAP), respectively. On transplantation into the striatum, CM-DiI labeled iPSC-derived NSCs were found to migrate into the ischemia area at 1 week and 2 weeks, and animal-function recovery was significantly improved in comparison with control groups at 3 weeks. Conclusions The four-stage induction system is stable and effective to culture, differentiate, and induce iPSCs to NSCs by using serum-free medium combined with retinoic acid (RA). Implanted iPSC-derived NSCs were able to survive, migrate into the ischemic brain area to differentiate into mature neural cells, and seem to have potential to restore lost neurologic function from damage due to stroke in a rat model.

Abstract
As a milestone breakthrough of stem cell and regenerative medicine in recent years, somatic cell reprogramming has opened up new applications of regenerative medicine by breaking through the ethical shackles of embryonic stem cells. However, induced pluripotent stem (iPS) cells are prepared with a complicated protocol that results in a low reprogramming rate. To obtain differentiated target cells, iPS cells and embryonic stem cells still need to be induced using step-by-step procedures. The safety of induced target cells from iPS cells is currently a further concerning matter. More broadly conceived is lineage reprogramming that has been investigated since 1987. Adult stem cell plasticity, which triggered interest in stem cell research at the end of the last century, can also be included in the scope of lineage reprogramming. With the promotion of iPS cell research, lineage reprogramming is now considered as one of the most promising fields in regenerative medicine, will hopefully lead to customized, personalized therapeutic options for patients in the future.

Abstract
Numerous researches demonstrated the possibility of derivation of Schwann-like (SC-like) cells in vitro from bone marrow stromal cells (BMSCs). However, the concentration of the induce factors were different in those studies, especially for the critical factors forskolin (FSK) and β-heregulin (HRG). Here, we used a new and useful method to build an integrated microfluidic chip for rapid analyses of the optimal combination between the induce factors FSK and HRG. The microfluidic device was mainly composed of an upstream concentration gradient generator (CGG) and a downstream cell culture module. Rat BMSCs were cultured in the cell chambers for 11 days at the different concentrations of induce factors generated by CGG. The result of immunofluorescence staining on-chip showed that the group of 4.00 µM FSK and 250.00 ng/ml HRG presented an optimal effect to promote the derivation of SC-like cells. Moreover, the optimal SC-like cells obtained on-chip were further tested using DRG co-culture and ELISA to detect their functional performance. Our findings demonstrate that SC-like cells could be obtained with high efficiency and functional performance in the optimal inducers combination.

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
This study aimed to determine the optimal dosage range of NT-3 in the soluble form or loaded with chitosan carriers by using NT-3/chitosan carriers to support the survival and proliferation of neural stem cells (NSCs) and induce them to differentiate into desired phenotypes. NSCs were co-cultured with chitosan carriers loaded with different doses of NT-3. As the control, NSCs were cultured in the defined medium, into which were added different doses of NT-3 in the soluble form every day. The ELISA kit was used to study the NT-3 releasing kinetics, which showed that, in the initial co-culture stage from 1 h to 14 weeks, the chitosan carriers loaded with different doses of NT-3 released NT-3 stably and constantly. The 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay was conducted to measure the cell viability, and the immunocytochemical methods were adopted to quantitatively analyze the phenotypes differentiating from the NSCs. Compared to the 100 ng NT-3 daily addition group (1400 ng over 14 days), the 25 ng, 50 ng and 200 ng NT-3 daily addition group showed dramatically shorter processes length and much lower differentiation percentage from NSCs into neurons. By contrast, the NT-3 (25 ng)-chitosan carriers group had not only higher cell viability, but also similar processes length and differentiation percentage from NSCs into neurons to the 100 ng NT-3 daily addition group. The method developed in this study significantly reduced the NT-3 amount required to support the survival, proliferation and differentiation of NSCs in vitro. Meanwhile, the chitosan carriers used here provided an ideal 3-dimensional scaffold for the adhesion, migration, proliferation and differentiation of NSC and the differentiated cells. Therefore, this method may open a new field for the large-scaled culture and amplification of NSCs in vitro to replace the lost neural cells, meanwhile lower the consumption of neurotrophic factors in the cell transplantation therapy of brain and spinal injury.

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
Adult mesenchymal stem cells derived from adipose tissue (A-MSC) have the capacity to differentiate in vitro into mesenchymal as well as endodermal and ectodermal cell lineages. We investigated the neuronal differentiation potential of human A-MSC with a protocol which included sphere formation and sequential culture in brain-derived neurotrophic factor (BDNF) and retinoic acid (RA). After 30 days, about 57% A-MSC showed morphological, immunocytochemical and electrophysiological evidence of initial neuronal differentiation. In fact, A-MSC displayed elongated shape with protrusion of two or three cellular processes, selectively expressed nestin and neuronal molecules (including GABA receptor and tyroxine hydroxilase) in the absence of glial phenotypic markers. Differentiated cells showed negative membrane potential (-60 mV), delayed rectifier potassium currents and TTX-sensitive sodium currents. Such changes were stable for at least 7 days after removal of differentiation medium. In view of these results and the easy availability of adipose tissue, A-MSC may be a ready source of adult MSC with neuronal differentiation potential, an useful tool to treat neurodegenerative diseases.

Abstract
Poor survival and insufficient neuronal differentiation are the main obstacles to neural stem cell (NSC) transplantation therapy. Genetic modification of NSCs with neurotrophins is considered a promising approach to overcome these difficulties. In this study, the effects on survival, proliferation and neuronal differentiation of human fetal NSCs (hfNSCs) were observed after infection by a neurotrophin-3 (NT-3) recombinant retrovirus. The hfNSCs, from 12-week human fetal brains formed neurospheres, expressed the stem cell marker nestin and differentiated into the three main cell types of the nervous system. NT-3 recombinant retrovirus (Retro-NT-3) infected hfNSCs efficiently expressed NT-3 gene for at least 8 weeks, presented an accelerated proliferation, and therefore produced an increased number of neurospheres and after differentiation in vitro, contained a higher percentage of neuronal cells. Eight weeks after infection, 37.9+/-4.2% of hfNSCs in the Retro-NT-3 infection group expressed the neuronal marker, this was significantly higher than the control and mock infection groups. NT-3 transduced hfNSCs also displayed longer protruding neurites compared with other groups. Combined these results demonstrate that NT-3 modification promote the survival/proliferation, neuronal differentiation and growth of neurites of hfNSCs in vitro. This study proposes recombinant retrovirus mediated NT-3 modification may provide a promising means to resolve the poor survival and insufficient neuronal differentiation of NSCs.

Abstract
Previously, we found that suppressing phosphatidylcholine-specific phospholipase C could induce neuronal differentiation of rat mesenchymal stem cells in the absence of serum and fibroblast growth factor. It is well known that basic fibroblast growth factor plays an important role in mesenchymal stem cell neuronal differentiation. In this study, our purpose was to understand the cooperation of phosphatidylcholine-specific phospholipase C and basic fibroblast growth factor in controlling mesenchymal stem cell neuronal differentiation. Our results showed that suppressing phosphatidylcholine-specific phospholipase C in the presence of basic fibroblast growth factor could induce cell neuronal differentiation and the viability of the differentiated cells was obviously increased. Furthermore, we found that the resting membrane potential of the differentiated cells gradually decreased, but the mitochondrial membrane potential rose with increasing treatment time and these characteristics were similar to cultured neurons from mouse embryo forebrains. To determine the possible mechanism by which this combination controls cell neuronal differentiation, we measured changes in the mitochondrial membrane potential and in the levels of reactive oxygen species. The results showed that both the mitochondrial membrane potential and reactive oxygen species levels decreased when basic fibroblast growth factor was added. The data suggested that lower phosphatidylcholine-specific phospholipase C activity was required for mesenchymal stem cell neuronal differentiation and basic fibroblast growth factor was necessary for maintaining the neuronal differentiation state. Moreover, basic fibroblast growth factor could contribute to rescuing the differentiated cells from death through decreasing overly high mitochondrial membrane potentials and reactive oxygen species levels.

Abstract
This study aims to investigate the effect of adenoviral vector-mediated neurotrophine-3 (NT-3) gene transfer and retinoic acid (RA) pretreatment on inducing neuronal differentiation of bone marrow mesenchymal stem cells (MSCs) in vitro. MSCs could be efficiently transduced by NT-3 gene via recombinant adenoviral vectors (Adv). Combination of AdvNT-3 and RA significantly promoted MSCs to differentiate into cell types associated with phenotypes of neural lineages, which included neural markers nestin, NF, MAP2 and PSD95 as detected by immunocytochemistry. But the expressions of GFAP in these cells were not obvious. RT-PCR analysis revealed that AdvNT-3 in combination with RA pretreatment could initiate the transcription of TrkC mRNA. These results demonstrate that the combination of AdvNT-3 and RA pretreatment may promote neuronal differentiation of MSCs, which may serve as ideal seed cells for the repair of spinal cord injury.

Abstract
Mesenchymal stem cells (MSCs) were evaluated as an alternative source for tissue engineering of peripheral nerves. MSCs, transdifferentiated MSCs, or Schwann cells cultured from male rats were grafted into devitalized autologous muscle conduits bridging a 2-cm sciatic nerve gap in female rats. The differentiation potential of MSCs and transformed cultivated MSCs into Schwann cell-like cells was exploited using a cocktail of cytokines. Polymerase chain reaction of the SRY gene confirmed the presence of the implanted cells in the grafts. After 6 weeks, regeneration was monitored clinically, histologically, and morphometrically. Autologous nerves and cell-free muscle grafts were used as control. Revascularization studies suggested that transdifferentiated MSCs, in contrast to undifferentiated MSCs, facilitated neo-angiogenesis and did not influence macrophage recruitment. Autologous nerve grafts demonstrated the best results in all regenerative parameters. An appropriate regeneration was noted in the Schwann cell-groups and, albeit with restrictions, in the transdifferentiated MSC groups, whereas regeneration in the MSC group and in the cell-free group was impaired. The results indicate that transdifferentiated MSCs implanted into devitalized muscle grafts are able to support peripheral nerve regeneration to some extent, and offer a potential for new therapeutic strategies.

Abstract
Bone marrow stromal cells (MSC) are multipotent stem cells that differentiate into cells of the mesodermal lineage. Although adult, their differentiation potential is remarkable, and they are able to transdifferentiate. Transdifferentiated cultivated rat MSC (tMSC) changed morphologically into cells resembling typical spindle-shaped Schwann cells (SC) with enhanced expression of LNGF receptor, Krox-20, CD104 and S100beta protein and decreased expression of bone morphogenetic protein receptor-1A compared to untreated rat MSC (rMSC). Transdifferentiation was reversible and repeatable. To evaluate the myelinating capacity, rMSC, tMSC, or SC cultured from male rats were grafted into an autologous muscle conduit bridging a 2-cm gap in the female rat sciatic nerve. The presence of the male-specific SRY gene (as revealed by PCR analysis) and S100 immunoreactivity of pre-labeled tMSC confirmed the presence of the implanted cells in the grafts. Three weeks after grafting, an appropriate regeneration was noted in the SC and in the tMSC groups, while regeneration in the rMSC group and in the control group without any cells was impaired. In contrast to SC, in some cases, single tMSC were able to myelinate more than one axon. Our findings demonstrate that it may be possible to differentiate MSC into therapeutically useful cells for clinical applications.

Abstract
Classically, bone marrow mesenchymal stem cells (MSC) differentiate in vivo or in vitro into osteocytes, chondrocytes, fibroblasts and adipocytes. Recently, it was reported by several groups that MSC can also adopt a neural fate in appropriate in vivo or in vitro experimental conditions. However, it is unclear if those cells are really able to differentiate into functional neural cells and in particular into functional neurons. Some observations suggest that a cell fusion process underlies the neural fate adoption by MSC in vivo and first attempts to reproduce in vitro this neural fate decision in MSC cultures were unsuccessful. More recently, however, in several laboratories including ours, differentiation of MSC cultivated from adult rat bone marrow into astrocytes and neuron-like cells was demonstrated. More precisely, we stressed the importance of the expression by MSC of nestin, an intermediate filament protein associated with immaturity in the nervous system, as a pre-requisite to adopting an astrocytic or a neuronal fate in a co-culture paradigm. Using this approach, we have also demonstrated that the MSC-derived neuron-like cells exhibit several electrophysiological key properties classically devoted to neurons, including firing of action potentials. In this review, we will discuss the neurogenic potential of MSC, the factor(s) required for such plasticity, the molecular mechanism(s) underlying this neural plasticity, the importance of the environment of MSC to adopt this neural fate and the therapeutic potential of these observations.
