Distinctive mesenchymal-like neurofibroma stem cells shape NF1 clinical phenotypes controlled by BDNF microenvironment. Transl Oncol 2024; 40:101852. [PMID: 38042136 PMCID: PMC10716025 DOI: 10.1016/j.tranon.2023.101852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 10/23/2023] [Accepted: 11/27/2023] [Indexed: 12/04/2023] Open
Abstract
BACKGROUND Neurofibroma type I (NF1) often presents with multiple clinical phenotypes due to mutations of NF1 gene. The aim of this study was to determine the phenotypic and therapeutic relevance of tumor microenvironment in NF1 patients. METHODS Tumor stem cells (TSCs) from NF1 were isolated and cultured using fluorescence activated cell sorting (FACS) and colony formation experiments. Then, flow cytometry was used to detect the surface markers, osteogenic and adipogenic differentiation were performed as well. Its tumorigenesis ability was confirmed by subcutaneous tumorigenesis in nude mice. Immunohistochemical staining was performed on neurofibroma tissues from the head and trunk with different phenotypes. The expression of BDNF in neurofibroma tissues was detected by Elisa and immunohistochemical staining. Western Blotting was used to detect the expression of p38 MAPK pathway in TSCs. The effect of BDNF neutralizing antibody on the tumorigenesis of TSCs was observed. RESULTS Herein, we advocate that NF1 contain a new subgroup of mesenchymal-like neurofibroma stem cells (MNSCs). Such colony-forming MNSCs preserved self-renewal, multiple differentiation and tumorigenic capabilities. More interestingly, the MNSCs isolated from neurofibroma tissues of the same patient with different phenotypes presented site-specific capabilities. Moreover, different levels of brain-derived neurotrophic factor (BDNF) in neurofibroma tissues can impact the MNSCs by activating the TrkB/p38 MAPK pathway. Systemic administration of BDNF neutralizing antibodies inhibited MNSCs' characteristics. CONCLUSIONS We demonstrated that BDNF can modulate MNSCs and thereby controlling different tumor phenotypes between the head and trunk regions. Application of BDNF neutralizing antibodies may inhibit p38 MAPK pathway, therefore providing a promising strategy for managing NF1.

Abstract
In this study, we investigated whether human umbilical cord mesenchymal stem cell (hUCMSC) fibrin patches loaded with nerve growth factor (NGF) poly(lactic-co-glycolic acid) (PLGA) nanoparticles could enhance the therapeutic potency of hUCMSCs for myocardial infarction (MI). In vitro, NGF significantly improved the proliferation of hUCMSCs and mitigated cytotoxicity and apoptosis under hypoxic injury. NGF also promoted the paracrine effects of hUCMSCs on angiogenesis and cardiomyocyte protection. The tyrosine kinase A (TrkA) and phosphoinositide 3-kinase (PI3K)-serine/threonine protein kinase (Akt) signaling pathways in hUCMSCs were involved in the NGF-induced protection. NGF PLGA nanoparticles continued to release NGF for at least 1 mo and also exerted a protective effect on hUCMSCs, the same with free NGF. In vivo, we treated MI mice with nothing (MI group), a cell-free fibrin patch with blank PLGA nanoparticles (MI + OP group), a cell-free fibrin patch with NGF nanoparticles (MI + NGF group), and hUCMSC fibrin patches with blank PLGA nanoparticles (MI + MSC group) or NGF PLGA nanoparticles (MSC + NGF group). Among these groups, the MSC + NGF group exhibited the best cardiac contractile function, the smallest infarct size, and the thickest ventricular wall. The application of NGF PLGA nanoparticles significantly improved the retention of transplanted hUCMSCs and enhanced their ability to reduce myocardial apoptosis and promote angiogenesis in the mouse heart after MI. These findings demonstrate the promising therapeutic potential of hUCMSC fibrin cardiac patches loaded with NGF PLGA nanoparticles.NEW & NOTEWORTHY NGF PLGA nanoparticles can exert a protective effect on hUCMSCs and promote the paracrine effects of hUCMSCs on angiogenesis and cardiomyocyte protection through TrkA-PI3K/Akt signaling pathway, the same with free NGF. The application of NGF PLGA nanoparticles in the hUCMSC fibrin cardiac patches can significantly improve the retention of transplanted hUCMSCs and enhance their ability to reduce myocardial apoptosis and promote angiogenesis in the mouse heart after MI.

Abstract
Mesenchymal stem/stromal cells (MSCs) are promising for the treatment of degenerative diseases and traumatic injuries. However, MSC engraftment is not always successful and requires a strong comprehension of the cytokines and their receptors that mediate the biological behaviors of MSCs. The effects of nerve growth factor (NGF) and its two receptors, TrkA and p75NTR, on neural cells are well studied. Increasing evidence shows that NGF, TrkA, and p75NTR are also involved in various aspects of MSC function, including their survival, growth, differentiation, and angiogenesis. The regulatory effect of NGF on MSCs is thought to be achieved mainly through its binding to TrkA. p75NTR, another receptor of NGF, is regarded as a novel surface marker of MSCs. This review provides an overview of advances in understanding the roles of NGF and its receptors in MSCs as well as the effects of MSC‐derived NGF on other cell types, which will provide new insight for the optimization of MSC‐based therapy.

Int J Mol Sci 2021; 22:E829. [PMID: 33467640 PMCID: PMC7830385 DOI: 10.3390/ijms22020829] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 01/10/2021] [Accepted: 01/11/2021] [Indexed: 12/17/2022] Open
Abstract
Mesenchymal stem cells (MSCs) are a promising therapy to improve vascular repair, yet their role in ischemic retinopathy is not fully understood. The aim of this study is to investigate the impact of modulating the neurotrophin receptor; p75NTR on the vascular protection of MSCs in an acute model of retinal ischemia/reperfusion (I/R). Wild type (WT) and p75NTR-/- mice were subjected to I/R injury by increasing intra-ocular pressure to 120 mmHg for 45 min, followed by perfusion. Murine GFP-labeled MSCs (100,000 cells/eye) were injected intravitreally 2 days post-I/R and vascular homing was assessed 1 week later. Acellular capillaries were counted using trypsin digest 10-days post-I/R. In vitro, MSC-p75NTR was modulated either genetically using siRNA or pharmacologically using the p75NTR modulator; LM11A-31, and conditioned media were co-cultured with human retinal endothelial cells (HREs) to examine the angiogenic response. Finally, visual function in mice undergoing retinal I/R and receiving LM11A-31 was assessed by visual-clue water-maze test. I/R significantly increased the number of acellular capillaries (3.2-Fold) in WT retinas, which was partially ameliorated in p75NTR-/- retinas. GFP-MSCs were successfully incorporated and engrafted into retinal vasculature 1 week post injection and normalized the number of acellular capillaries in p75NTR-/- retinas, yet ischemic WT retinas maintained a 2-Fold increase. Silencing p75NTR on GFP-MSCs coincided with a higher number of cells homing to the ischemic WT retinal vasculature and normalized the number of acellular capillaries when compared to ischemic WT retinas receiving scrambled-GFP-MSCs. In vitro, silencing p75NTR-MSCs enhanced their secretome, as evidenced by significant increases in SDF-1, VEGF and NGF release in MSCs conditioned medium; improved paracrine angiogenic response in HREs, where HREs showed enhanced migration (1.4-Fold) and tube formation (2-Fold) compared to controls. In parallel, modulating MSCs-p75NTR using LM11A-31 resulted in a similar improvement in MSCs secretome and the enhanced paracrine angiogenic potential of HREs. Further, intervention with LM11A-31 significantly mitigated the decline in visual acuity post retinal I/R injury. In conclusion, p75NTR modulation can potentiate the therapeutic potential of MSCs to harness vascular repair in ischemic retinopathy diseases.

Cell Biochem Funct 2019; 37:359-367. [PMID: 31066473 DOI: 10.1002/cbf.3404] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2019] [Revised: 03/22/2019] [Accepted: 04/05/2019] [Indexed: 12/14/2022]
Abstract
This study aimed to investigate the mechanism of nerve growth factor (NGF) from cobra venom and human transforming growth factor-β1 (TGF-β1) on the chondrogenic induction of mesenchymal stem cells (MSCs). NGF and TGF-β1 were used to induce chondrogenesis of MSCs from rabbits for 7 days. Total RNA was extracted for mRNA sequencing. Differentially expressed genes (DEGs), gene ontology (GO), KEGG pathway enrichment, and PPI network analysis were conducted to screen the specific signalling pathways and target genes. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to further confirm the relative target genes. The results showed that NGF could significantly promote the expression of hyaline cartilage specific genes (collagen type II alpha 1 chain, COL2A1) compared with TGF-β1. PI3K-AKT signalling pathway is commonly involved in the chondrogenesis of MSCs induced by NGF and TGF-β1. However, the expression levels of the genes in the PI3K-AKT signalling pathway were significantly higher in NGF group than that in the TGF-β1 group. In the process of chondrogenesis of MSCs induced by NGF and TGF-β1, integrin (ITGAs) were the targeted hub genes to activate the PI3K-AKT signalling pathway. NGF could activate more proliferation and differentiation genes in the process of chondrogenesis of MSCs than TGF-β1. TGF-β1 promoted angiogenesis by targeting the thrombospondin (THBS1) and THBS2 which might contribute to the osteophyte formation. PI3K-AKT was the crucial signalling pathway for chondrogenic differentiation. NGF could activate the PI3K-AKT signalling pathway to a higher level, and NGF had more specificity for promoting expression of specific genes of chondrocyte compared with TGF-β1. SIGNIFICANCE OF THE STUDY: In our study, we compared two different growth factors in promoting cartilage differentiation of MSCs and found some similarities and differences. We revealed that both NGF and TGF-β1 could activate the PI3K-AKT signalling pathway (the expression of it in NGF was higher) by targeting the ITGAs in the process of chondrogenesis from MSCs. However, NGF could activate more proliferation and differentiation genes in the process of chondrogenesis of MSCs, whereas TGF-β1 caused osteophyte formation by activating THBS1 and THBS2. These might be the reason why NGF could promote cartilage differentiation more specifically.

Abstract
The effects of low-level laser therapy (LLLT) and natural latex protein (F1, Hevea brasiliensis) were evaluated on crush-type injuries (15kg) to the sciatic nerve in the expressions of nerve growth factor (NGF) and vascular endothelium growth factor (VEGF) and ultrastructural morphology to associate with previous morphometric data using the same protocol of injury and treatment. Thirty-six male rats were allocated into six experimental groups (n = 6): 1-Control; 2-Exposed nerve; 3-Injured nerve; 4-LLLT (15J/cm2, 780nm, 30mW, Continuous Wave) treated injured nerve; 5-F1 (0,1mg) treated injured nerve; and 6-LLLT&F1 treated injured nerve. Four or eight weeks after, sciatic nerve samples were processed for analysis. NGF expression were higher (p<0.05) four weeks after in all injured groups in comparison to Control (Med:0.8; Q1:0; Q3:55.5%area). Among them, the Injured (Med:70.7; Q1:64.4; Q3:77.5%area) showed the highest expression, and F1 (Med:17.3; Q1:14.1; Q3:21.7%area) had the lowest. At week 8, NGF expressions decreased in the injured groups. VEGF was expressed in all groups; its higher expression was observed in the injured groups 4 weeks after (Injured. Med:29.5; F1. Med:17.7 and LLLT&F1. Med:19.4%area). At week 8, a general reduction of VEGF expression was noted, remaining higher in F1 (Med:35.1; Q1.30.6; Q3.39.6%area) and LLLT&F1 (Med:18.5; Q1:16; Q3:25%area). Ultrastructural morphology revealed improvements in the treated groups; 4 weeks after, the F1 group presented greater quantity and diameter of the nerve fibers uniformly distributed. Eight weeks after, the F1 and LLLT&F1 showed similar characteristics to the non-injured groups. In summary, these results and our previous studies indicated that F1 and LLLT may favorably influence the healing of nerve crush injury. Four weeks after nerve injury F1 group showed the best results suggesting recovery acceleration; at 8th week F1 and LLLT&F1 groups presented better features and higher vascularization that could be associated with VEGF maintenance.

Abstract
Neuropeptide Y (NPY), a powerful neurotransmitter of the central nervous system, is a key regulator of angiogenesis and biology of adipose depots. Intriguingly, its peripheral vascular and angiogenic powerful activity is strictly associated to platelets, which are source of clinical hemoderivates, such as platelet lysate (PL), routinely employed in several clinical applications as wound healing, and to preserve ex vivo the progenitor properties of the adipose stromal cells pool. So far, the presence of NPY in PL and its biological effects on the adipose stromal cell fraction (ASCs) have never been investigated. Here, we aimed to identify endogenous sources of NPY such as PL-based preparations and to investigate which biological properties PL-derived NPY is able to exert on ASCs. The results show that PL contains a high amount of NPY, which is in part also excreted by ASCs when stimulated with PL. The protein levels of the three main NPY subtype receptors (Y1, Y2, Y5) are unaltered by stimulation of ASCs with PL, but their inhibition through selective pharmacological antagonists, considerably enhances migration, and a parallel reduction of angiogenic features of ASCs including decrease in VEGF mRNA and intracellular calcium levels, both downstream targets of NPY. The expression of VEGF and NPY is enhanced within the sites of neovascularisation of difficult wounds in patients after treatment with leuco-platelet concentrates. Our data highlight the presence of NPY in PL preparations and its peripheral effects on adipose progenitors.

Differentiation of adipose-derived stem cells into Schwann cell-like cells through intermittent induction: potential advantage of cellular transient memory function. Stem Cell Res Ther 2018; 9:133. [PMID: 29751848 PMCID: PMC5948899 DOI: 10.1186/s13287-018-0884-3] [Citation(s) in RCA: 41] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Revised: 04/02/2018] [Accepted: 04/20/2018] [Indexed: 12/11/2022] Open
Abstract
Background Peripheral nerve injury (PNI) is a worldwide issue associated with severe social and economic burden. Autologous nerve grafting, the gold standard treatment for peripheral nerve defects, still has a number of technical limitations. Tissue engineering technology is a novel therapeutic strategy, and mesenchymal stromal cells (MSCs) are promising seed cells for nerve tissue engineering. However, the efficiency of traditional methods for inducing the differentiation of MSCs to Schwann cell-like cells (SCLCs) remains unsatisfactory. Methods Here, we propose an intermittent induction method with alternate use of complete and incomplete induction medium to induce differentiation of adipose-derived stem cells (ASCs) to SCLCs. The time dependence of traditional induction methods and the efficiency of the intermittent induction method and traditional induction methods were evaluated and compared using immunocytochemistry, quantitative reverse transcription polymerase chain reaction (qRT-PCR), enzyme-linked immunosorbent assay (ELISA), and co-culture with the dorsal root ganglion (DRG) in vitro. Cell transplantation was used to compare the effects of the traditional induction method and the intermittent induction method in repairing sciatic nerve defects in vivo. Results The results of the present study indicated that the intermittent induction method is more efficient than traditional methods for inducing ASCs to differentiate into SCLCs. In addition, SCLCs induced by this method were closer to mature myelinating Schwann cells and were capable of secreting neurotrophins and promoting DRG axon regeneration in vitro. Furthermore, SCLCs induced by the intermittent induction method could repair sciatic nerve defects in rats by cell transplantation in vivo more effectively than those produced by traditional methods. Conclusion Intermittent induction represents a novel strategy for obtaining seed cells for use in nerve tissue engineering.

Abstract
A potential alternative for tissue transplants is tissue engineering, in which the interaction of cells and biomaterials can be optimized. Tissue development in vitro depends on the complex interaction of several biological processes such as extracellular matrix synthesis, vascularization and cell proliferation, adhesion, migration, death, and differentiation. The complexity of an individual phenomenon or of the combination of these processes can be studied with phenomenological modeling techniques. This work reviews the main biological phenomena in tissue development and their mathematical modeling, focusing on mesenchymal stem cell growth in three-dimensional scaffolds.

Abstract
The placenta has emerged as an attractive source of mesenchymal stem cells (MSCs) because of the absence of ethical issues, non-invasive access, and abundant yield. However, inflammatory cell invasion into grafts negatively impacts the survival and efficacy of transplanted cells. Previous studies have shown that synthetic C16 peptide can competitively block the transmigration of leukocytes into the central nerve system, while angiopoietin-1 (Ang-1) can inhibit inflammation-induced blood vessel leakage and inflammatory cell infiltration in rats with experimental allergic encephalomyelitis (EAE). In this study, we investigated the effects of intravenous administration of C16 and Ang-1 on the efficacy of placenta-derived MSC (PMSC) transplantation in a rat model of EAE. We found that, compared with PMSCs alone, treatment with PMSCs along with intravenously administered C16 and Ang-1 was more effective at ameliorating demyelination/neuronal loss and neurological dysfunction, reducing inflammatory cell infiltration, perivascular edema, and reactive astrogliosis (p < 0.05). Mechanistic studies revealed that intravenous C16 and Ang-1 increased PMSC engraftment in the central nervous system and promoted expression of the neurotropic proteins brain-derived neurotrophic factor, growth-associated protein 43, and p75 neurotrophin receptor as well as the neuronal-glial lineage markers neurofilament protein 200 and myelin basic protein in the engrafted PMSCs.

Abstract
Growth factors such as transforming growth factor beta1 (TGF-β1), have critical roles in the regulation of the chondrogenic differentiation of mesenchymal stem cells (MSCs), which promote cartilage repair. However, the clinical applications of the traditional growth factors are limited by their high cost, functional heterogeneity and unpredictable effects, such as cyst formation. It may be advantageous for cartilage regeneration to identify a low-cost substitute with greater chondral specificity and easy accessibility. As a neuropeptide, nerve growth factor (NGF) was involved in cartilage metabolism and NGF is hypothesized to mediate the chondrogenic differentiation of MSCs. We isolated NGF from Chinese cobra venom using a three-step procedure that we had improved upon from previous studies, and investigated the chondrogenic potential of NGF on bone marrow MSCs (BMSCs) both in vitro and in vivo. The results showed that NGF greatly upregulated the expression of cartilage-specific markers. When applied to cartilage repair for 4, 8 and 12 weeks, NGF-treated BMSCs have greater therapeutic effect than untreated BMSCs. Although inferior to TGF-β1 regarding its chondrogenic potential, NGF showed considerably lower expression of collagen type I, which is a fibrocartilage marker, and RUNX2, which is critical for terminal chondrocyte differentiation than TGF-β1, indicating its chondral specificity. Interestingly, NGF rarely induced BMSCs to differentiate into a neuronal phenotype, which may be due to the presence of other chondrogenic supplements. Furthermore, the underlying mechanism revealed that NGF-mediated chondrogenesis may be associated with the activation of PI3K/AKT and MAPK/ERK signaling pathways via the specific receptor of NGF, TrkA. In addition, NGF is easily accessed because of the abundance and low price of cobra venom, as well as the simplified methods for separation and purification. This study was the first to demonstrate the chondrogenic potential of NGF, which may provide a reference for cartilage regeneration in the clinic.

Abstract
Objective Treatment and repair of neurodegenerative diseases such as brain tumors,
spinal cord injuries, and functional disorders, including Alzheimer’s disease, are challenging problems. A common treatment approach for such disorders involves the use of
mesenchymal stem cells (MSCs) as an alternative cell source to replace injured cells.
However, use of these cells in hosts may potentially cause adverse outcomes such as tumorigenesis and uncontrolled differentiation. In attempt to generate mesenchymal derived
neural cells, we have infected MSCs with recombinant lentiviruses that expressed nerve
growth factor (NGF) and assessed their neural lineage genes.
Materials and Methods In this experimental study, we cloned the NGF gene sequence
into a helper dependent lentiviral vector that contained the green fluorescent protein (GFP)
gene. The recombinant vector was amplified in DH5 bacterial cells. Recombinant viruses
were generated in the human embryonic kidney 293 (HEK-293) packaging cell line with
the helper vectors and analyzed under fluorescent microscopy. Bone marrow mesenchymal cells were infected by recombinant viruses for three days followed by assessment of
neural differentiation. We evaluated expression of NGF through measurement of the NGF
protein in culture medium by ELISA; neural specific genes were quantified by real-time
polymerase chain reaction (PCR).
Results We observed neural morphological changes after three days. Quantitative PCR
showed that expressions of NESTIN, glial derived neurotrophic factor (GDNF), glial fibrillary acidic protein (GFAP) and Microtubule-associated protein 2 (MAP2) genes increased
following induction of NGF overexpression, whereas expressions of endogenous NGF
and brain derived neural growth factor (BDNF) genes reduced.
Conclusion Ectopic expression of NGF can induce neurogenesis in MSCs. Direct injection of MSCs may cause tumorigenesis and an undesirable outcome. Therefore an
alternative choice to overcome this obstacle may be the utilization of differentiated neural
stem cells.

Abstract
Mesenchymal stem cells (MSC) are regarded as an attractive source of therapeutic stem cells for myocardial infarction. However, their limited self-renewal capacity, low migration capacity and poor viability after transplantation hamper the clinical use of MSC; thus, a strategy to enhance the biological functions of MSC is required. Exendin-4 (Ex-4), a glucagon-like peptide-1 receptor agonist, exerts cell-protective effects on many types of cells. However, little information is available regarding the influence of Ex-4 on MSC. In our study, MSC were isolated from bone marrow and cultured in vitro. After treatment with Ex-4, MSC displayed a higher proliferative capacity, increased C-X-C motif receptor 4 (CXCR4) expression and an enhanced migration response. Moreover, in H2O2-induced apoptosis, Ex-4 preserved mitochondrial function through scavenging ROS and balancing the expression of anti- and pro-apoptotic proteins, leading to the inhibition of the mitochondria-dependent cell death pathways and increased cell survival. Moreover, higher phospho-Akt (p-Akt) expression was observed after Ex-4 intervention. However, blockade of the PI3K/Akt pathway with inhibitors suppressed the above cytoprotective effects of Ex-4, suggesting that the PI3K/Akt pathway is partly responsible for Ex-4-mediated MSC growth, mobilization and survival. These findings provide an attractive method of maximizing the effectiveness of MSC-based therapies in clinical applications.

Abstract
Congenital insensitivity to pain with anhidrosis (CIPA) is a rare inherited disorder of the peripheral nervous system resulting from mutations in neurotrophic tyrosine kinase receptor 1 gene (NTRK1), which encodes the high-affinity nerve growth factor receptor TRKA. Here, we investigated the oral and craniofacial manifestations of a Chinese patient affected by autosomal-recessive CIPA and identified compound heterozygosity in the NTRK1 gene. The affected boy has multisystemic disorder with lack of reaction to pain stimuli accompanied by self-mutilation behavior, the inability to sweat leading to defective thermoregulation, and mental retardation. Oral and craniofacial manifestations included a large number of missing teeth, nasal malformation, submucous cleft palate, severe soft tissue injuries, dental caries and malocclusion. Histopathological evaluation of the skin sample revealed severe peripheral nerve fiber loss as well as mild loss and absent innervation of sweat glands. Ultrastructural and morphometric studies of a shed tooth revealed dental abnormalities, including hypomineralization, dentin hypoplasia, cementogenesis defects and a dysplastic periodontal ligament. Genetic analysis revealed a compound heterozygosity- c.1561T>C and c.2057G>A in the NTRK1 gene. This report extends the spectrum of NTRK1 mutations observed in patients diagnosed with CIPA and provides additional insight for clinical and molecular diagnosis.

Abstract
Angiogenesis is a major obstacle for wound healing in patients with diabetic foot wounds. Mesenchymal stem cells (MSCs) have an important function in wound repair, and neurotrophin-3 (NT-3) can promote nerve regeneration and angiogenesis. We investigated the effect of NT-3 on accelerating wound healing in the diabetic foot by improving human bone marrow MSC (hMSC) activation. In vitro, NT-3 significantly promoted VEGF, NGF, and BDNF secretion in hMSCs. NT-3 improved activation of the hMSC conditioned medium, promoted human umbilical vein endothelial cell (HUVEC) proliferation and migration, and significantly improved the closure rate of HUVEC scratches. In addition, we produced nanofiber mesh biological tissue materials through the electrospinning technique using polylactic acid, mixed silk, and collagen. The hMSCs stimulated by NT-3 were implanted into the material. Compared with the control group, the NT-3-stimulated hMSCs in the biological tissue material significantly promoted angiogenesis in the feet of diabetic C57BL/6J mice and accelerated diabetic foot wound healing. These results suggest that NT-3 significantly promotes hMSC secretion of VEGF, NGF, and other vasoactive factors and that it accelerates wound healing by inducing angiogenesis through improved activation of vascular endothelial cells. The hMSCs stimulated by NT-3 can produce materials that accelerate wound healing in the diabetic foot and other ischemic ulcers.

Abstract
AIM To investigate the neuroprotective effects of LLDT-67, a novel derivative of triptolide, in MPTP-induced mouse Parkinson's disease (PD) models and in primary cultured astrocytes, and to elucidate the mechanisms of the action. METHODS In order to induce PD, C57BL/6 mice were injected MPTP (30 mg/kg, ip) daily from d 2 to d 6. MPTP-induced behavioral changes in the mice were examined using pole test, swimming test and open field test. The mice were administered LLDT-67 (1, 2, or 4 mg/kg, po) daily from d 1 to d 11. On d 12, the mice were decapitated and brains were collected for immunohistochemistry study and measuring monoamine levels in the striatum. Primary cultured astrocytes from the cortices of neonatal C57BL/6 mouse pups were prepared for in vitro study. RESULTS In MPTP-treated mice, administration of LLDT-67 significantly reduced the loss of tyrosine hydroxylase-positive neurons in the substantia nigra, and ameliorated the behavioral changes. LLDT-67 (4 mg/kg) significantly increased the expression of NGF in astrocytes in the substantia nigra and striatum of the mice. Furthermore, administration of LLDT-67 caused approximately 2-fold increases in the phosphorylation of TrkA at tyrosine 751, and marked increases in the phosphorylation of AKT at serine 473 as compared with the mice model group. In the cultured astrocytes, LLDT-67 (1 and 10 nmol/L) increased the NGF levels in the culture medium by 179% and 160%, respectively. CONCLUSION The neuroprotective effect of LLDT-67 can be mostly attributed to its ability to enhance NGF synthesis in astrocytes in the midbrain and to rescue dopaminergic neurons indirectly through TrkA activation.
