Clin Biochem 2024; 127-128:110760. [PMID: 38556035 DOI: 10.1016/j.clinbiochem.2024.110760] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 02/28/2024] [Accepted: 03/28/2024] [Indexed: 04/02/2024]
Abstract
BACKGROUND Recent data show that netrin-1 has a role in development of pulmonary fibrosis. This study was aimed to investigate serum netrin-1 level and its relation to interstitial lung disease(ILD) in patients with rheumatoid arthritis (RA). METHOD 42 RA patients with RA-ILD, 58 RA patients without RA-ILD (RA non-ILD group), and 61 healthy volunteers were included in this study. The modified DAS28-ESR score was used to calculate disease activity in RA patients. Using the quantitative immunoassay method, Serum netrin-1 levels were measured with an ELISA kit (Catalog number: E-EL-H2328; lab science, lot number: GZWTKZ5SWK, Texas, USA). RESULTS The median value of netrin-1 was found to be significantly higher in the RA-ILD group (82.9 [59.9-124]) compared to both the RA non-ILD group(52.9 [49.5-73.1])(B = -0.006, OR = 0.994, CI 95 %=0.989-0.999, P = 0.018) and the control group(53.5 [49.5-87.5]) (B: -0.005, OR: 0.994, CI 95 %: 0.990-0.999, p: 0.022). A cut-off value of 61.78 for netrin-1 was found to have a sensitivity of 73.8 % and a specificity of 69 % for the diagnosis of RA-ILD (AUC [95 %Cl] = 0.771 [0.679-0.862], p < 0.0001).It was found that high serum netrin-1 level was strongly associated with the RA-usual interstitial pneumonia(UIP) pattern and poorly related to the RA-nonspecific interstitial pneumonia(NSIP) pattern compared to the RA non-ILD group. CONCLUSIONS Netrin-1 is elevated in the serum of patients with RA-ILD, especially in the UIP pattern. Netrin-1 may be a potential candidate for predicting the development of RA-ILD that should be investigated in the pathophysiological and therapeutic fields..

Abstract
At present, the vascular grafts used in clinic are mainly autologous blood vessels, but they often face the dilemma of no blood vessels available due to limited sources. However, synthetic blood vessels made of polytetrafluoroethylene (ePTFE), which is commonly used in clinic, are prone to thrombosis and intimal hyperplasia, and the long-term patency rate is poor, so its effectiveness is severely limited, which is far from meeting the clinical needs. With the development of nano-materials, stem cells and 3D bio-printing technology, people began to explore the preparation of new endothelialized vascular grafts through this technology. Nano-peptide materials have excellent biocompatibility, can be compounded with different bioactive molecules, and have unique advantages in cultivating stem cells. It has been reported that self-assembled nano-polypeptide hydrogel was successfully constructed, mesenchymal stem cells were correctly isolated and cultured, and their transformation into blood vessels was studied. It was confirmed that the 3D bio-printed nano-polypeptide hydrogel tissue ADMSCs still had strong vascular endothelial differentiation ability. The application of mesenchymal stem cells and nano-polypeptide hydrogel in tissue engineering blood vessels has gradually become a research hotspot, and it is expected to develop a new type of transplanted blood vessel that meets the physiological functions of human body in terms of vascular endothelialization, cell compatibility and histocompatibility, so as to realize the customized and personalized printing of the endothelialized transplanted blood vessel according to the shape of the target blood vessel, which has attractive prospects and far-reaching social and economic benefits.

Abstract
This work was aimed to explore the effect of recombinant netrin-1 protein and peripheral blood mesenchymal stem cells (MSCs) on the angiogenesis ability of atherosclerosis. 28 Sprague Dawley (SD) rats were taken as research models. The arterial occlusion models were created by surgery and then divided into the saline control group (n =7), netrin-1 treatment group (n =7), MSCs treatment group (n =7), and netrin-1 + MSCs combined treatment group (n =7). The peripheral blood MSCs were extracted from the peritoneal cavity of diseased SD rats and cultured alone or in combination with netrin-1. The individually cultured MSCs and netrin-1 were locally injected into the ischemic tissues of SD rats. The Tarlov scoring was performed at the first, second, and third week of treatment, respectively. The expression of vascular endothelial growth factor (VEGF) was also measured by quantitative real-time polymerase chain reaction (qRT-PCR), and the capillary density was measured by immunofluorescence staining. The mean maximum contractility of the gastrocnemius muscle in each group was determined in the third week after treatment. The Tarlov score of the netrin-1 + MSCs group was significantly higher than that of the control group (P < 0.05) at the second week. To the 4th week of treatment, the Tarlov score of the netrin-1 + MSCs group was highly increased compared to the netrin-1 group and the MSCs group (P < 0.05). The expression of VEGF in the treatment groups was greatly increased each week compared to the control group (P < 0.05). Compared with the netrin-1 and the MSCs groups, the VEGF was also notably increased in the netrin-1 + MSCs group (P <0.05). The capillary densities of the treatment groups were observably greater than that of the control group in the second and third weeks (P <0.05), while the capillary density in the netrin-1 + MSCs group was also significantly increased than those in the netrin-1 group and the MSCs group (P < 0.05). The mean maximum contractility of the netrin-1 + MSCs group was remarkably higher than that of the other groups (P < 0.05). The netrin-1 + MSCs group achieved the higher Tarlov score, higher VEGF expression, higher capillary density, and better muscle recovery than netrin-1 and MSCs treatments.

Abstract
Objective: This study aimed to observe the cell growth status and multidirectional differentiation ability in a 3D-bioprinted tissue model of self-assembled nanopeptides and human adipose-derived mesenchymal stem cells (Ad-MSCs). Methods: Primary Ad-MSCs were isolated, cultured, and identified by flow cytometry. Tissue models were printed via 3D bioprinting technology using a “biological ink” consisting of a mixed solution of self-assembled nanopeptides and Ad-MSCs. Ad-MSCs were induced into osteogenic, adipogenic, and endothelial differentiation and compared with the control groups by staining. Results: The nanopeptide fiber was 10–30 nm in diameter and 200–500 nm in length under the atomic-force microscope. It had the characteristics of nano-scale materials. Flow cytometry showed that the isolated and cultured cells were positive for CD29 (98.51%), CD90 (97.87%), and CD166 (98.32%) but did not express CD31 (1.58%), CD34 (2.42%), CD45 (2.95%), or human leukocyte antigen (HLA)-DR (0.53%), consistent with the immunophenotype of Ad-MSCs. Then, a tissue model was printed using the biological ink, followed by induction of differentiation of Ad-MSCs within the tissue model. Alizarin red S staining showed the formation of calcium nodules in the osteogenesis induction experimental group, and oil red O stained lipid droplets in Ad-MSCs in the adipogenesis induction experimental group, whereas the two control groups were not stained. Conclusion: Ad-MSCs from primary cultures have the characteristics of stem cells. Self-assembled nanopeptide hydrogel is a good tissue engineering material that can serve as an extracellular matrix. Ad-MSCs in the 3D-printed tissue model using a biological ink consisting of a mixed solution of self-assembled nanopeptides and Ad-MSCs grew well and still had strong differentiation ability.

Abstract
Peripheral arterial disease (PAD) is an increasingly common narrowing of the peripheral arteries that can lead to lower limb ischemia, muscle weakness and gangrene. Surgical vein or arterial grafts could improve PAD, but may not be suitable in elderly patients, prompting research into less invasive approaches. Mesenchymal stem cells (MSCs) have been proposed as potential therapy, but their effectiveness and underlying mechanisms in limb ischemia are unclear. We tested the hypothesis that treatment with naive MSCs (nMSCs) or MSCs expressing CD146 (CD146+MSCs) could improve vascularity and muscle function in rat model of hind-limb ischemia. Sixteen month old Sprague-Dawley rats were randomly assigned to 4 groups: sham-operated control, ischemia, ischemia + nMSCs and ischemia+CD146+MSCs. After 4 weeks of respective treatment, rat groups were assessed for ischemic clinical score, Tarlov score, muscle capillary density, TUNEL apoptosis assay, contractile force, and vascular endothelial growth factor (VEGF) mRNA expression. CD146+MSCs showed greater CD146 mRNA expression than nMSCs. Treatment with nMSCs or CD146+MSCs improved clinical and Tarlov scores, muscle capillary density, contractile force and VEGF mRNA expression in ischemic limbs as compared to non-treated ischemia group. The improvements in muscle vascularity and function were particularly greater in ischemia+CD146+MSCs than ischemia + nMSCs group. TUNEL positive apoptotic cells were least abundant in ischemia+CD146+MSCs compared with ischemia + nMSCs and non-treated ischemia groups. Thus, MSCs particularly those expressing CD146 improve vascularity, muscle function and VEGF expression and reduce apoptosis in rat ischemic limb, and could represent a promising approach to improve angiogenesis and muscle function in PAD.

Association between serum netrin-1 and prognosis of ischemic stroke: The role of lipid component levels. Nutr Metab Cardiovasc Dis 2021; 31:852-859.

Abstract
BACKGROUND AND AIMS High serum netrin-1 levels decrease the risk of ischemic stroke and are negatively associated with outcomes after ischemic stroke. However, it remains unclear whether the association between netrin-1 and ischemic stroke prognosis is modified by lipid component levels. METHODS AND RESULTS We measured baseline serum netrin-1 levels in 3065 ischemic stroke patients from China Antihypertensive Trial in Acute Ischemic Stroke (CATIS). The primary outcome was a combination of death and major disability (modified Rankin Scale score≥3) at 3 months after ischemic stroke. Total cholesterol (TC) levels could modify the association between netrin-1 and prognosis of ischemic stroke (Pinteraction = 0.040). After multivariate adjustment, the odds ratios of the primary outcome associated with the highest quartile of netrin-1 were 0.39 (95%CI, 0.17-0.90; Ptrend = 0.004) for the patients with high TC levels and 0.82 (95%CI, 0.61-1.11; Ptrend = 0.149) for those with normal TC levels. Adding netrin-1 to conventional risk factors improved risk prediction for the primary outcome in the patients with high TC levels (net reclassification improvement: 26.8%, P = 0.015; integrated discrimination index: 1.6%, P = 0.028) but not in those with normal TC levels. CONCLUSIONS Elevated netrin-1 is associated with improved prognosis at 3 months after ischemic stroke in the patients with high TC levels but not in those with normal TC levels. Further prospective studies from other populations and randomized clinical trials are needed to verify our findings and clarify the potential mechanisms.

Autologous peripheral blood-derived stem cells transplantation for treatment of no-option angiitis-induced critical limb ischemia: 10-year management experience. Stem Cell Res Ther 2020; 11:458. [PMID: 33115517 PMCID: PMC7594448 DOI: 10.1186/s13287-020-01981-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Accepted: 10/19/2020] [Indexed: 02/07/2023] Open
Abstract
Background Previous studies have demonstrated that no-option angiitis-induced critical limb ischemia (NO-AICLI) could be significantly improved by transplantation of peripheral blood-derived stem cells (PBDSCs). Additionally, a randomized controlled trial (RCT) recently conducted by us suggested that peripheral blood-derived purified CD34+ cells (PCCs) were not inferior to non-purified peripheral blood mononuclear cells (PBMNCs) at limb salvage in treatment of NO-AICLI. However, most of these clinical trials whether RCT or single-arm studies were characterized with a small sample size and absence of long-term outcomes. Methods To analyze long-term clinical outcomes of PBDSCs transplantation for NO-AICLI, we reviewed clinical data of patients with NO-AICLI receiving PBDSCs transplantation at our center during the past decade. Meanwhile, we first compared the long-term safety and efficacy of intramuscular transplantation of PCCs versus PBMNCs in a sizable number of patients with NO-AICLI. Results From May 2009 to December 2019, a total of 160 patients with NO-AICLI patients were treated by PBDSCs transplantation (82 with PCCs, 78 with PBMNCs) at our center. Baseline characteristics between two groups were similar. Up to June 2020, the mean follow-up period was 46.6 ± 35.3 months. No critical adverse events were observed in either group. There was one death during the follow-up period. A total of eight major amputations occurred. The cumulative major amputation-free survival (MAFS) rate at 5 years after PBDSCs transplantation was 94.4%, without difference between two groups (P = .855). Wound healing, rest pain, pain-free walking time, ankle-brachial index, transcutaneous oxygen pressure, and quality of life (QoL) also significantly improved after PBDSCs transplantation. Conclusions Autologous PBDSCs intramuscular transplantation could significantly decrease the major amputation rates and improve the QoL in patients with NO-AICLI. Long-term observation of a large sample of patients confirmed that the clinical benefits of PBDSCs transplantation were durable, without difference between the PCCs and PBMNCs groups.

Abstract
Introduction Mesenchymal stem cells (MSCs) have always been the center of the experimental exploration of regenerative therapy together with other stem cells. Among with, peripheral blood-derived mesenchymal stem cells (PBMSCs) have been regarded as promising in clinical applications for its convenience of acquisition from peripheral blood. However, few reported experiments so far to elucidate the exact mechanisms of how PBMSC influence regeneration. As the ability of immunomodulatory is one of the crucial features that influence MSC to reconstruct impaired tissue, we decided to focus on the immunomodulatory abilities of PBMSCs and conducted experiments associated with macrophages and T lymphocytes, which are two main cell types that dominate the innate and acquired immunity. Therefore, a basis can be made from these experiments for applications of PBMSCs in regenerative therapy in the future. Methods A Transwell system was used for the coculturing of PBMSCs with macrophages. T lymphocytes were cultured directly with PBMSCs. Flow cytometry and immunochemistry were conducted for identifying the phenotypes. Immunomagnetic microspheres, ELISA and RT-qPCR were used to detect the expressions of relevant molecules or mRNAs. Results After coculturing PBMSCs with M0, the anti-inflammatory IL-10 was increased whereas the proinflammatory TNF-α decreased; the expression of CD11b, CD68, CD206, Arg-1, IL-10 and CCL-22 was up-regulated whereas IL-1β down-regulated. The expression of TGF-β, RORγt, Foxp3 and IL-10 was increased in the cocultured lymphocytes whereas IL-17 and IL-6 decreased; the ratio of CD4+IL-17+ Th17/CD25+Foxp3+ Treg was reduced. Conclusion The findings demonstrated that PBMSCs promoted the anti-inflammatory features of macrophages and the Th17/Treg system. PBMSCs are able to inhibit inflammation associated with these two immune cell systems, and thus provide insight into how PBMSCs achieve their immunomodulatory ability. Anti-inflammatory effect of peripheral blood-derived mesenchymal stem cells. Co-culture promotes the polarization of M2 macrophages. Co-culture alters the balance of Th17/Tregs.

Blood vessels and nerves coordinate with each other in function, while neurotrophin-3 (NT-3) is an important class of nerve growth factors. Our study found that NT-3 promoted endothelial progenitor cell (EPC) mobilization, and the proportion of EPCs in peripheral blood was increased by 1.774 times compared with the control group. Besides, NT-3 promoted the expression of stromal cell-derived factor-1α (SDF-1α), matrix metalloproteinase-9 (MMP9), and chemokine (C-X-C motif) receptor 4 (CXCR4) in EPCs, which increased by 59.89%, 74.46%, and 107.7%, respectively, compared with the control group. Transwell experiments showed that NT-3 enhanced the migration of EPCs by 1.31 times. Flow chamber experiments demonstrated that NT-3 captured more circulating EPCs. As shown by ELISA results, NT-3 can promote the paracrine of vascular endothelial growth factor, interleukin-8, MMP-9, and SDF-1 from EPCs. Such increased angiogenic growth factors further accelerated the closure of endothelial cell scratches. Additionally, EPC-conditioned medium in the NT-3 group significantly inhibited the proliferation of vascular smooth muscle cells. Then animal experiments also illustrated that NT-3 prominently accelerated the endothelialization of injured carotid artery. In short, NT-3 accelerated rapid reendothelialization of injured carotid artery through promoting EPC mobilization and homing.

Effects of intra-arterial transplantation of adipose-derived stem cells on the expression of netrin-1 and its receptor DCC in the peri-infarct cortex after experimental stroke. Stem Cell Res Ther 2017; 8:223. [PMID: 29017609 PMCID: PMC5633888 DOI: 10.1186/s13287-017-0671-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2017] [Revised: 09/11/2017] [Accepted: 09/13/2017] [Indexed: 12/16/2022] Open
Abstract
Background Stem cell transplantation has been documented to promote functional recovery in animal models of stroke; however, the underlying mechanisms are not yet fully understood. As netrin-1 and its receptor deleted in colorectal cancer (DCC) are important regulators in neuronal and vascular activities, the present study attempted to explore whether netrin-1 and DCC are involved in the neuroprotection of stem cell-based therapies in a rat ischemic stroke model. Methods Adult male Sprague–Dawley rats were subjected to a transient middle cerebral artery occlusion (MCAO) and subsequently received an intra-arterial injection of 2 × 106 PKH26-labeled adipose-derived stem cells (ADSCs) or saline 24 h later. Neurological function was evaluated by behavioral tests before the rats were sacrificed at days 7 and 14 after MCAO. The migration of ADSCs and regeneration of neuronal fibers and blood vessels were determined by immunofluorescence staining. The expression of netrin-1 and DCC was analyzed by Western blot and immunofluorescence staining. Results ADSC transplantation significantly improved the neurological recovery at days 7 and 14, and noticeably promoted the regeneration of neuronal fibers and blood vessels in the peri-infarct cortex at day 14. PKH26-labeled ADSCs located mainly in the peri-infarct area at days 7 and 14. In ADSC-treated rats, the expression of netrin-1 and DCC significantly increased in the peri-infarct cortex at days 7 and 14. Immunofluorescence staining showed that netrin-1 was mainly expressed by neuronal perikaryal in the peri-infarct cortex, and DCC was mainly expressed by neuronal fibers and was present around the blood vessels in the peri-infarct cortex. Conclusions These findings suggest that ADSC transplantation facilitates the regeneration of neuronal fibers and blood vessels in the peri-infarct cortex and improves neurological functions, which may be attributed, at least in part, to the involvement of upregulated netrin-1 and DCC in the remodeling of neuronal and vascular networks in the peri-infarct cortex.

Abstract
Stroke is a leading cause of morbidity and mortality worldwide. Administration of Netrin-1 during the peri-infarct period has been shown to decrease infarct size in rats; however, the underlying mechanism is unclear. We addressed this question in the present study by inducing stroke in rats via middle cerebral artery occlusion (MCAO), and evaluating the effects of Netrin-1 treatment by neurobehavioral testing, immunocytochemistry, and western blotting. Netrin-1 overexpression increased neurobehavioral test scores and reduced cerebral infarct volume following MCAO via inhibition of the Notch1 signaling pathway. These results demonstrate that early administration of Netrin-1 can is an effective therapeutic approach for improving outcome after stroke. © 2017 Wiley Periodicals, Inc.
