Feng J, Xing M, Qian W, Qiu J, Liu X. An injectable hydrogel combining medicine and matrix with anti-inflammatory and pro-angiogenic properties for potential treatment of myocardial infarction. Regen Biomater 2023; 10:rbad036. [PMID: 37153848 PMCID: PMC10159687 DOI: 10.1093/rb/rbad036] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 03/20/2023] [Accepted: 04/07/2023] [Indexed: 05/10/2023] Open
Abstract
One of the main illnesses that put people's health in jeopardy is myocardial infarction (MI). After MI, damaged or dead cells set off an initial inflammatory response that thins the ventricle wall and degrades the extracellular matrix. At the same time, the ischemia and hypoxic conditions resulting from MI lead to significant capillary obstruction and rupture, impairing cardiac function and reducing blood flow to the heart. Therefore, attenuating the initial inflammatory response and promoting angiogenesis are very important for the treatment of MI. Here, to reduce inflammation and promote angiogenesis in infarcted area, we report a new kind of injectable hydrogel composed of puerarin and chitosan via in situ self-assembly with simultaneous delivery of mesoporous silica nanoparticles (CHP@Si) for myocardial repair. On the one hand, puerarin degraded from CHP@Si hydrogel modulated the inflammatory response via inhibiting M1-type polarization of macrophages and expression of pro-inflammatory factors. On the other hand, silica ions and puerarin released from CHP@Si hydrogel showed synergistic activity to improve the cell viability, migration and angiogenic gene expression of HUVECs in both conventional and oxygen/glucose-deprived environments. It suggests that this multifunctional injectable CHP@Si hydrogel with good biocompatibility may be an appropriate candidate as a bioactive material for myocardial repair post-MI.

Abstract
Cardiovascular diseases (CVDs) are responsible for enormous socio-economic impact and the highest mortality globally. The standard of care for CVDs, which includes medications and surgical interventions, in most cases, can delay but not prevent the progression of disease. Gene therapy has been considered as a potential therapy to improve the outcomes of CVDs as it targets the molecular mechanisms implicated in heart failure. Cardiac reprogramming, therapeutic angiogenesis using growth factors, antioxidant, and anti-apoptotic therapies are the modalities of cardiac gene therapy that have led to promising results in preclinical studies. Despite the benefits observed in animal studies, the attempts to translate them to humans have been inconsistent so far. Low concentration of the gene product at the target site, incomplete understanding of the molecular pathways of the disease, selected gene delivery method, difference between animal models and humans among others are probable causes of the inconsistent results in clinics. In this review, we discuss the most recent applications of the aforementioned gene therapy strategies to improve cardiac tissue regeneration in preclinical and clinical studies as well as the challenges associated with them. In addition, we consider ongoing gene therapy clinical trials focused on cardiac regeneration in CVDs.

Abstract
Mesenchymal stem cells (MSCs) are being used to treat many diseases as they exhibit great regenerative potential. However, MSC's transplantation sometimes does not yield the maximum regenerative outcome as they are unable to survive in inflammatory conditions. Several approaches including preconditioning are used to improve the survival rate of mesenchymal stem cells. One such recently reported approach is preconditioning MSCs with plant extracts. The present study was designed to evaluate the effect of Daphne mucronata extract on stressed human adipose-derived mesenchymal stem cells (hADMSCs). Isolated hADMSCs were preconditioned with different concentrations of Daphne muconata extract and the protective, proliferative, antioxidant and anti-inflammatory effect was assessed through various assays and expression analysis of inflammatory markers regulated through NF-κB pathway. Results suggest that preconditioning hADMSCs with Daphne mucronata increased the cell viability, proliferative and protective potential of hADMSCs with a concomitant reduction in LDH, ROS and elevation in SOD activity. Moreover, both the ELISA and gene expression analysis demonstrated down regulations of inflammatory markers (IL1-β, TNF-α, p65, p50, MMP13) in Daphne mucronata preconditioned hADMSCs as compared to stress. This is the first study to report the use of MIA induced oxidative stress against hADMSC's and effect of Daphne mucronata on stressed hADMSCs. Results of these studies provided evidence that Daphne mucronata protects the hADMSCs during stress conditions by down regulating the inflammatory markers and hence increase the viability and proliferative potential of hADMSCs that is crucial for transplantation purposes.

Abstract
Ischemic heart disease and myocardial infarction remain leading causes of mortality worldwide. Existing myocardial infarction treatments are incapable of fully repairing and regenerating the infarcted myocardium. Stem cell transplantation therapy has demonstrated promising results in improving heart function following myocardial infarction. However, poor cell survival and low engraftment at the harsh and hostile environment at the site of infarction limit the regeneration potential of stem cells. Preconditioning with various physical and chemical factors, as well as genetic modification and cellular reprogramming, are strategies that could potentially optimize stem cell transplantation therapy for clinical application. In this review, we discuss the most up-to-date findings related to utilizing preconditioned stem cells for myocardial infarction treatment, focusing mainly on preconditioning with hypoxia, growth factors, drugs, and biological agents. Furthermore, genetic manipulations on stem cells, such as the overexpression of specific proteins, regulation of microRNAs, and cellular reprogramming to improve their efficiency in myocardial infarction treatment, are discussed as well.

Abstract
Myocardial infarction causes cardiac tissue damage and the release of damage-associated molecular patterns leads to activation of the immune system, production of inflammatory mediators, and migration of various cells to the site of infarction. This complex response further aggravates tissue damage by generating oxidative stress, but it eventually heals the infarction site with the formation of fibrotic tissue and left ventricle remodeling. However, the limited self-renewal capability of cardiomyocytes cannot support sufficient cardiac tissue regeneration after extensive myocardial injury, thus, leading to an irreversible decline in heart function. Approaches to improve cardiac tissue regeneration include transplantation of stem cells and delivery of inflammation modulatory and wound healing factors. Nevertheless, the harsh environment at the site of infarction, which consists of, but is not limited to, oxidative stress, hypoxia, and deficiency of nutrients, is detrimental to stem cell survival and the bioactivity of the delivered factors. The use of biomaterials represents a unique and innovative approach for protecting the loaded factors from degradation, decreasing side effects by reducing the used dosage, and increasing the retention and survival rate of the loaded cells. Biomaterials with loaded stem cells and immunomodulating and tissue-regenerating factors can be used to ameliorate inflammation, improve angiogenesis, reduce fibrosis, and generate functional cardiac tissue. In this review, we discuss recent findings in the utilization of biomaterials to enhance cytokine/growth factor and stem cell therapy for cardiac tissue regeneration in small animals with myocardial infarction.

Abstract
During acute myocardial infarction (AMI), Ischemia/Reperfusion (I/R) injury causes cardiomyocyte (CM) death and loss of tissue function, making AMI one of the major causes of death worldwide. Cell-based in vitro models of I/R injury have been increasingly used as a complementary approach to preclinical research. However, most approaches use murine cells in 2D culture setups, which are not able to recapitulate human cellular physiology, as well as nutrient and gas gradients occurring in the myocardium. In this work we established a novel human in vitro model of myocardial I/R injury using CMs derived from human induced pluripotent stem cells (hiPSC-CMs), which were cultured as 3D aggregates in stirred tank bioreactors. We were able to recapitulate important hallmarks of AMI, including loss of CM viability with disruption of cellular ultrastructure, increased angiogenic potential, and secretion of key proangiogenic and proinflammatory cytokines. Conditioned medium was further used to probe human cardiac progenitor cells (hCPCs) response to paracrine cues from injured hiPSC-CMs through quantitative whole proteome analysis (SWATH-MS). I/R injury hiPSC-CM conditioned media incubation caused upregulation of hCPC proteins associated with migration, proliferation, paracrine signaling, and stress response-related pathways, when compared to the control media incubation. Our results indicate that the model developed herein can serve as a novel tool to interrogate mechanisms of action of human cardiac populations upon AMI.

Abstract
BACKGROUND Xueshuan-Xinmai-Ning Tablet (XXNT), a commercially available patent drug, has been extensively used in the treatment of coronary heart disease (CHD) with a satisfying therapeutic efficacy. The aim of this study was to explore the underlying pharmacological mechanisms of XXNT acting on CHD. STUDY DESIGN An integrative pharmacology-based investigation was performed. METHOD Putative targets of composite compounds contained in XXNT were predicted using the Drug Target Prediction Tool in the Computation Platform for Integrative Pharmacology of Traditional Chinese Medicine (TCMIP, www.tcmip.cn) and MedChem Studio. Then, an interaction network of XXNT putative targets-known CHD-related genes was constructed, and candidate XXNT targets related to its therapeutic effects on CHD were identified by calculating three major network topological features. Functional enrichment analysis was performed to investigate the specific functions and pathways involved by the candidate XXNT targets acting on CHD, which were further validated by in vitro experiments. RESULTS A total of 742 putative targets hit 126 chemical components contained in XXNT were predicted. Following the construction of XXNT putative target-known CHD-related gene network, and the network topological feature calculation, we identified 51 candidate XXNT targets related to its therapeutic effects on CHD. Functionally, these candidate XXNT targets were significantly associated with various cardiovascular system-related pathways, sedation-related pathways, inflammatory and immune-related pathways and endocrine/metabolic system-related pathways. More importantly, the in vitro experiment validation confirmed the regulatory effects of XXNT in SRC, VEGF and VEGFR-1, which play roles in VEGF signaling pathway, based on the endothelial injury cell model. CONCLUSION Our findings reveal that XXNT may attenuate the major pathological changes of CHD through regulating its candidate targets, which might be involved into the signal transductions in nervous-endocrine-immune-cardiovascular-metabolic system.

Abstract
Systemic inflammatory response syndrome is a complex pathophysiologic and immunologic response to an insult. Sepsis is a life-threatening condition happening when the body's response to infection causes injury to its own tissues and organs. Stem cell therapy is a new approach to modulate immune responses. Mesenchymal stem cells (MSCs) establish a regenerative niche by secreting secretome and modulating immune responses. MSC secretome can be leveraged for therapeutic applications if production of secretary molecules were optimized. Pharmacological preconditioning using small molecules can increase survival of MSCs after transplantation. The aim of this study was to investigate the effect of secretome of human embryonic-derived mesenchymal stem cells (hESC-MSCs) preconditioned with MG-132,Trimetazidine (TMZ) and Diazoxide (DZ) on immunomodulatory efficiency of these cells in Lipo polysaccharide (LPS) challenged mice models. Mice were injected intraperitoneally with LPS and groups of animals were intraperitoneally given 1 ml 30× secretome 6 h after LPS injection. Serum levels of biochemical parameters were then measured by an auto analyser and serum inflammatory cytokine levels were analysed using commercially available RayBio Mouse Inflammation Antibody Array. Ultimately, histopathology and survival studies were conducted. The results showed that TMZ and DZ-conditioned medium significantly increasing the survival and improvement of histopathological score. We found that MG-132-conditioned medium failed to show significant outcomes. This study demonstrated that human MSC secretome has the potential to control inflammation.

Abstract
Transplanted stem/progenitor cells improve tissue healing and regeneration anatomically and functionally, mostly due to their secreted trophic factors. However, harsh conditions at the site of injury, including hypoxia, oxidative and inflammatory stress, increased fibrosis and insufficient angiogenesis, and in some cases immunological response or incompatibility, are detrimental to stem cell survival. To overcome the complexity and deficiencies of stem cell therapy, the coacervate delivery platform is deemed promising because it offers controlled and sustained release using heparin to recapitulate the binding and stabilization of extracellular proteins by heparan sulphates in native tissues. Here we show that recombinant alternatives of three key factors [vascular endothelial growth factor (VEGF), monocyte chemoattractant protein-1 (MCP-1) and interleukin-6 (IL-6)], commonly produced by perivascular stem cells under various stress conditions, can be successfully incorporated into a heparin-based coacervate. We characterized the release profile of the triply incorporated factors from the complex coacervate. The coacervate-released factors were able to exert their desired biological activities in vitro: VEGF stimulated human umbilical vein endothelial cell proliferation, MCP-1 elevated macrophage migration and IL-6 increased IgM production by IL-6-dependent cell line. Thus, a controlled release system can be used for simultaneous delivery of three stem cell-derived factors and could be useful for tissue repair and regenerative medicine.

Abstract
INTRODUCTION The immune system plays a crucial role in the initiation, development, and resolution of inflammation following myocardial infarction (MI). The lack of oxygen and nutrients causes the death of cardiomyocytes and leads to the exposure of danger-associated molecular patterns that are recognized by the immune system to initiate inflammation. RESULTS At the initial stage of post-MI inflammation, the immune system further damages cardiac tissue to clear cell debris. The excessive production of reactive oxygen species (ROS) by immune cells and the inability of the anti-oxidant system to neutralize ROS cause oxidative stress that further aggravates inflammation. On the other hand, the cells of both innate and adaptive immune system and their secreted factors are critically instrumental in the very dynamic and complex processes of regulating inflammation and mediating cardiac repair. CONCLUSIONS It is important to decipher the balance between detrimental and beneficial effects of the immune system in MI. This enables us to identify better therapeutic targets for reducing the infarct size, sustaining the cardiac function, and minimizing the likelihood of heart failure. This review discusses the role of both innate and adaptive immune systems in cardiac tissue damage and repair in experimental models of MI.

Abstract
After myocardial infarction (MI), the heart undergoes fibrotic pathological remodeling instead of repair and regeneration. With multiple pathologies developing after MI, treatment using several proteins is expected to address this range of pathologies more effectively than a single-agent therapy. A factorial design of experiments study guided us to combine three complementary factors in one injection: tissue inhibitor of metalloproteinases-3 (TIMP-3) was embedded in a fibrin gel for signaling in the initial phase of the treatment, while basic fibroblast growth factor (FGF-2) and stromal cell-derived factor 1-alpha (SDF-1α) were embedded in heparin-based coacervates for sustained release and distributed within the same fibrin gel to exert their effects over a longer period. The gel was then tested in a rat model of myocardial infarction. Contractility of rat hearts treated with the protein coacervate-gel composite stabilized and slightly improved after the first week while contractility continued to decrease in rats treated with free proteins or saline over the 8 week study period. Hearts receiving the protein coacervate-gel composite treatment also exhibited reduced ventricular dilation, inflammation, fibrosis, and extracellular matrix (ECM) degradation. Revascularization, cardiomyocyte preservation, stem cell homing, and increased myocardial strain likely all contributed to the repair. This study demonstrates the potential of a multifactorial therapeutic approach in MI, using three complementary proteins delivered sequentially for comprehensive healing. The study also shows the necessity of controlled delivery for growth factors and cytokines to be an effective treatment.

Abstract
Methylprednisolone (MP) is currently the only drug confirmed to exhibit a neuroprotective effect on acute spinal cord injury (SCI). Vitamin C (VC) is a natural water-soluble antioxidant that exerts neuroprotective effects through eliminating free radical damage to nerve cells. Bone marrow mesenchymal stem cells (BMMSCs), as multipotent stem cells, are promising candidates in SCI repair. To evaluate the therapeutic effects of MP, VC and BMMSCs on traumatic SCI, 80 adult male rats were randomly divided into seven groups: control, SCI (SCI induction by weight-drop method), MP (SCI induction, followed by administration of 30 mg/kg MP via the tail vein, once every other 6 hours, for five times), VC (SCI induction, followed by intraperitoneal administration of 100 mg/kg VC once a day, for 28 days), MP + VC (SCI induction, followed by administration of MP and VC as the former), BMMSCs (SCI induction, followed by injection of 3 × 106 BMMSCs at the injury site), and BMMSCs + VC (SCI induction, followed by BMMSCs injection and VC administration as the former). Locomotor recovery was assessed using the Basso Mouse Scale. Injured spinal cord tissue was evaluated using hematoxylin-eosin staining and immunohistochemical staining. Expression of transforming growth factor-beta, tumor necrosis factor-alpha, and matrix metalloproteinase-2 genes was determined using real-time quantitative PCR. BMMSCs intervention better promoted recovery of nerve function of rats with SCI, mitigated nerve cell damage, and decreased expression of transforming growth factor-beta, tumor necrosis factor-alpha, and matrix metalloproteinase-2 genes than MP and/or VC. More importantly, BMMSCs in combination with VC induced more obvious improvements. These results suggest that VC can enhance the neuroprotective effects of BMMSCs against SCI.

Abstract
Mesenchymal stem cells (MSCs) have attracted the attention of researchers and clinicians for their ability to differentiate into a number of cell types, participate in tissue regeneration, and repair the damaged tissues by producing various growth factors and cytokines, as well as their unique immunoprivilege in alloreactive hosts. The immunomodulatory functions of exogenous MSCs have been widely investigated in immune-mediated inflammatory diseases and transplantation research. However, a harsh environment at the site of tissue injury/inflammation with insufficient oxygen supply, abundance of reactive oxygen species, and presence of other harmful molecules that damage the adoptively transferred cells collectively lead to low survival and engraftment of the transferred cells. Preconditioning of MSCs ex vivo by hypoxia, inflammatory stimulus, or other factors/conditions prior to their use in therapy is an adaptive strategy that prepares MSCs to survive in the harsh environment and to enhance their regulatory function of the local immune responses. This review focuses on a number of approaches in preconditioning human MSCs with the goal of augmenting their capacity to regulate both innate and adaptive immune responses.

Abstract
Stem cell transplantation is a promising tool for the treatment of neurodegenerative disorders, including Parkinson's disease (PD); however, the therapeutic routes and mechanisms of mechanical approaches to stem cell transplantation must be explored. This study tests the therapeutic effect of transplantation of rat bone marrow mesenchymal stem cells (MSCs) into the substantia nigra (SN) of the PD rat. 5-Bromo-2-deoxyuridine-labeled rat MSCs were transplanted into the SN of the 6-hydroxydopamine-injected side of PD rat brains. The behavioral changes in PD rats were examined before and 4 and 8 weeks after MSC transplantation. The expression of tyrosine hydroxylase (TH) in the SN and the striatum and the survival and differentiation of MSCs were assessed by immunohistochemical and double immunofluorescence techniques. Abnormal behavior of PD rats was significantly improved by the administration of bone marrow MSCs, and the number of TH-positive cells in the SN and the optical density of TH-positive fibers in the striatum were markedly increased. Transplanted MSCs can survive and migrate in the brain and differentiate into nestin-, neuron-specific enolase-, and GFAP-positive cells. Our findings suggest that transplantation of rat bone marrow MSCs into the SN of PD rats may provide therapeutic effects. © 2016 Wiley Periodicals, Inc.

Abstract
Ischemic heart disease is a leading cause of death worldwide. After the onset of myocardial infarction, many pathological changes take place and progress the disease towards heart failure. Pathologies such as ischemia, inflammation, cardiomyocyte death, ventricular remodeling and dilation, and interstitial fibrosis, develop and involve the signaling of many proteins. Proteins can play important roles in limiting or countering pathological changes after infarction. However, they typically have short half-lives in vivo in their free form and can benefit from the advantages offered by controlled release systems to overcome their challenges. The controlled delivery of an optimal combination of proteins per their physiologic spatiotemporal cues to the infarcted myocardium holds great potential to repair and regenerate the heart. The effectiveness of therapeutic interventions depends on the elucidation of the molecular mechanisms of the cargo proteins and the spatiotemporal control of their release. It is likely that multiple proteins will provide a more comprehensive and functional recovery of the heart in a controlled release strategy.

Abstract
INTRODUCTION Most studies on intracoronary bone marrow mononuclear cell transplantation for acute myocardial infarction involve treatment 3-7 days after primary percutaneous coronary intervention (PCI); however, the optimal timing is unknown. The present study assessed the therapeutic effect at different times after ST-elevation myocardial infarction. METHODS The present trial was not blinded. A total of 104 patients with a first ST-elevation myocardial infarction and a left ventricular ejection fraction below 50 %, who had PCI of the infarct-related artery, were randomly assigned to receive intracoronary infusion of bone marrow mononuclear cells within 24 hours (group A, n = 27), 3 to 7 days after PCI (group B, n = 26), or 7 to 30 days after PCI (group C, n = 26), or to the control group (n = 25), which received saline infusion performed immediately after emergency PCI. All patients in groups A, B and C received an injection of 15 ml cell suspension containing approximately 4.9 × 10(8) bone marrow mononuclear cells into the infarct-related artery after successful PCI. RESULTS Compared to control and group C patients, group A and B patients had a significantly higher absolute increase in left ventricular ejection fraction from baseline to 12 months (change: 3.4 ± 5.7 % in control, 7.9 ± 4.9 % in group A, 6.9 ± 3.9 % in group B, 4.7 ± 3.7 % in group C), a greater decrease in left ventricular end-systolic volumes (change: -6.4 ± 15.9 ml in control, -20.5 ± 13.3 ml in group A, -19.6 ± 11.1 ml in group B, -9.4 ± 16.3 ml in group C), and significantly greater myocardial perfusion (change from baseline: -4.7 ± 5.7 % in control, -7.8 ± 4.5 % in group A, -7.5 ± 2.9 % in group B, -5.0 ± 4.0 % in group C). Group A and B patients had similar beneficial effects on cardiac function (p = 0.163) and left ventricular geometry (left ventricular end-distolic volume: p = 0.685; left ventricular end-systolic volume: p = 0.622) assessed by echocardiography, whereas group C showed similar results to those of the control group. Group B showed more expensive care (p < 0.001) and longer hospital stays during the first month after emergency PCI (p < 0.001) than group A, with a similar improvement after repeat cardiac catheterization following emergency PCI. CONCLUSION Cell therapy in acute myocardial infarction patients that is given within 24 hours is similar to 3-7 days after the primary PCI. TRIAL REGISTRATION NCT02425358 , registered 30 April 2015.

Abstract
The aim was to examine the role of exogenous hydrogen sulfide (H2S) on cardiac remodeling in post-myocardial infarction (MI) rats. MI was induced in rats by ligation of coronary artery. After treatment with sodium hydrosulfide (NaHS, an exogenous H2S donor, 56 μM/kg·day) for 42 days, the effects of NaHS on left ventricular morphometric features, echocardiographic parameters, heme oxygenase-1 (HO-1), matrix metalloproteinases-9 (MMP-9), type I and type III collagen, vascular endothelial growth factor (VEGF), CD34, and α-smooth muscle actin (α-SMA) in the border zone of infarct area were analyzed to elucidate the protective mechanisms of exogenous H2S on cardiac function and fibrosis. Forty-two days post MI, NaHS-treatment resulted in a decrease in myocardial fibrotic area in association with decreased levels of type I, type III collagen and MMP-9 and improved cardiac function. Meanwhile, NaHS administration significantly increased cystathionine γ-lyase (CSE), HO-1, α-SMA, and VEGF expression. This effect was accompanied by an increase in vascular density in the border zone of infarcted myocardium. Our results provided the strong evidences that exogenous H2S prevented cardiac remodeling, at least in part, through inhibition of extracellular matrix accumulation and increase in vascular density.

Abstract
INTRODUCTION Since myoblasts have been limited by poor cell survival after cellular myoplasty, the major goal of the current study was to determine whether improving myoblast survival with an antioxidant could improve cardiac function after the transplantation of the myoblasts into an acute myocardial infarction. BACKGROUND We previously demonstrated that early myogenic progenitors such as muscle-derived stem cells (MDSCs) exhibited superior cell survival and improved cardiac repair after transplantation into infarcted hearts compared to myoblasts, which we partially attributed to MDSC's higher antioxidant levels. AIM To determine if antioxidant treatment could increase myoblast survival, subsequently improving cardiac function after myoblast transplantation into infarcted hearts. MATERIALS AND METHODS Myoblasts were pre-treated with the antioxidant N-acetylcysteine (NAC) or the glutathione depleter, diethyl maleate (DEM), and injected into infarcted murine hearts. Regenerative potential was monitored by cell survival and cardiac function. RESULTS At early time points, hearts injected with NAC-treated myoblasts exhibited increased donor cell survival, greater cell proliferation, and decreased cellular apoptosis, compared to untreated myoblasts. NAC-treated myoblasts significantly improved cardiac contractility, reduced fibrosis, and increased vascular density compared to DEM-treated myoblasts, but compared to untreated myoblasts, no difference was noted. DISCUSSION While early survival of myoblasts transplanted into infarcted hearts was augmented by NAC pre-treatment, cardiac function remained unchanged compared to non-treated myoblasts. CONCLUSION Despite improving cell survival with NAC treated myoblast transplantation in a MI heart, cardiac function remained similar to untreated myoblasts. These results suggest that the reduced cardiac regenerative potential of myoblasts, when compared to MDSCs, is not only attributable to cell survival but is probably also related to the secretion of paracrine factors by the MDSCs.
