Abstract
Cardiovascular diseases are the leading cause of global mortality, in which myocardial infarction accounts for 46% of total deaths. Although good progress has been achieved in medication and interventional techniques, a proven method to repair the damaged myocardium has not yet been determined. Stem cell therapy for damaged myocardial repair has evolved into a promising treatment for ischemic heart disease. However, low retention and poor survival of the injected stem cells are the major obstacles to achieving the intended therapeutic effects. Chinese botanical and other natural drug substances are a rich source of effective treatment for various diseases. As such, numerous studies have revealed the role of Chinese medicine in stem cell therapy for myocardial infarction treatment, including promoting proliferation, survival, migration, angiogenesis, and differentiation of stem cells. Here, we discuss the potential and limitations of stem cell therapy, as well as the regulatory mechanism of Chinese medicines underlying stem cell therapy. We focus on the evidence from pre-clinical trials and clinical practices, and based on traditional Chinese medicine theories, we further summarize the mechanisms of Chinese medicine treatment in stem cell therapy by the commonly used prescriptions. Despite the pre-clinical evidence showing that traditional Chinese medicine is helpful in stem cell therapy, there are still some limitations of traditional Chinese medicine therapy. We also systematically assess the detailed experimental design and reliability of included pharmacological research in our review. Strictly controlled animal models with multi-perspective pharmacokinetic profiles and high-grade clinical evidence with multi-disciplinary efforts are highly demanded in the future.

[DOI: 10.2174/1573412916999200423105153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022]
Abstract
Background:
Pedunculoside (PE) is a triterpene saponin from the barks of Ilex rotunda, a Traditional Chinese
Medicine called Jiubiying, which is used for the treatment of cold and fever, tonsillitis, sore throat, acute and chronic
hepatitis, etc. Previous studies have confirmed that crude extract orally has a significant therapeutic effect on myocardial
infarction.
Methods:
A simple, sensitive, and specific method by using UPLC-MS/MS to study the pharmacokinetics
of PE in rats was developed and validated, with ilexsaponin A as an internal standard. Methanol
was used as a protein precipitation reagent for blood sample extraction. A Waters Acquity C18 column
(2.1 mm × 50 mm, 1.7 μm) was used for chromatographic separation with a gradient elution of
CH3CN: 0.1% formic acid (0.3 mL·min-1). Negative ion electrospray ionization was used for detection
in multiple reaction monitoring mode.
Results:
PE was linear within the concentration range of 0.14-1118.00 ng/mL. The LLOQ was 0.14
ng/mL for the plasma samples. The intra-day and inter-day precision were ranged from 1.18% to
10.48%, while the accuracy ranged from -1.32% to 1.68%, indicating satisfactory precision and accuracy
of the assay. The extraction recoveries for PE and IS were ranged from 81.40% to 86.65%, with
no significant variation among the three concentrations, respectively. PE remained stable at room
temperature (25°C) for 3 h, in auto-sampler (4°C) for 24 h, after three freeze-thaw cycles, and in
long-term storage at ‒20°C for 30 days. The PK results of PE indicated its poor oral bioavailability
(3.37%).
Conclusion:
Non-compartmental pharmacokinetics parameters indicated that PE was rapidly distributed to the tissues
and metabolized. The pharmacokinetic data of this paper highlighted the first-time report of PE oral bioavailability with
two different administration manners, which will help to better understand how PE metabolized in rats and exert its
pharmacological effect in vivo.

Abstract
The study explored the cardioprotective role of the methanolic leaf extract of Nelumbo nucifera and nuciferine against isoproterenol-induced myocardial infarction (MI) in Wistar rats. Pretreatment with leaf extract and nuciferine (200 and 20 mg/kg body weight, respectively) against MI induced by isoproterenol (85 mg/kg body weight) significantly decreased heart weight; levels of cardiac markers such as lactate dehydrogenase and creatine kinase-MB were similar to those in controls. The treatment significantly increased the content of endogenous antioxidants and decreased lipid peroxidation in all treated groups. Treated groups showed a significant reduction in heartbeats per minute as compared with the MI-induced positive control. The MI-induced group showed pathological implications such as tachycardia, left atrial enlargement, and anterolateral ST-elevated MI, which were absent in treated groups. Histology confirmed that the leaf extract and nuciferine prevented structural abnormality and inflammation in heart and liver tissues of treated groups. On in silico analysis, nuciferine showed stronger binding interaction with both β1 and β2 adrenergic receptors than isoproterenol. Hence, the leaf extract of N. nucifera and nuciferine could be used as plant-based cardioprotective agents.

Abstract
Cardiovascular diseases are one of the main concerns, nowadays causing a high rate of mortality in the world. The majority of conventional treatment protects the heart from failure progression. As a novel therapeutic way, Regenerative medicine in the heart includes cellular and noncellular approaches. Despite the irrefutable privileges of noncellular aspects such as administration of exosomes, utilizing of miRNAs, and growth factors, they cannot reverse necrotic or ischemic myocardium, hence recruiting of stem cells to help regenerative therapy in the heart seems indispensable. Stem cell lineages are varied and divided into two main groups namely pluripotent and adult stem cells. Not only has each of which own regenerative capacity, benefits, and drawbacks, but their turnover also close correlates with the target organ and/or tissue as well as the stage and level of failure. In addition to inefficient tissue integration due to the defects in delivering methods and poor retention of transplanted cells, the complexity of the heart and its movement also make more rigorous the repair process. Hence, utilizing biomaterials can make a key route to tackle such obstacles. In this review, we evaluate some natural products which can help stem cells in regenerative medicine of the cardiovascular system.

Abstract
Geum japonicum Thunb. var. chinense (GJ) is a type of wild vegetable found in China and other Asian countries; it has been reported that its extracts possess a neuroprotective effect against cerebral ischemia reperfusion (CIR) injury. The aim of this study is to explore the effect GJ extracts on transient focal CIR injury and neurons apoptosis and to clarify its possible underlying mechanisms in vivo. Our results indicated that pretreatment with GJ extracts significantly ameliorated the infarct volume, decreased neurological deficits, lessened neural cells apoptosis, downregulated GFAP activity level, and increased surviving neurons. Moreover, GJ extracts preadministration increased Bcl-2 levels and attenuated the increase in the expressions of Bax and it also lowered the cleaved caspase-3 activity in ischemic cortex tissues which was caused by CIR and increased the expression of PI3K and p-Akt. The above effects of high dose of GJ (GJ-H) group were much better than those of low dose of GJ (GJ-L), which indicated that GJ extracts may be helpful in the suppression of CIR injury with a dose-dependent manner.

Abstract
Stem cell therapy is considered as a promising treatment for cardiovascular diseases. Adipose-derived mesenchymal stem cells (ADMSCs) have the ability to undergo cardiomyogenesis. Medicinal plants are effective and safe candidates for cell differentiation. Therefore, the aim of our study was to investigate cardiogenic effects of characterized (HPLC–UV) extracts of Geum urbanum on ADMSCs of adipose tissue. The methanolic extracts of the root and aerial parts of G. urbanum were obtained and MTT assay was used for studying their cytotoxic effects. Then, cells were treated with 50 or 100 μg/mL of the extracts from root and aerial parts of G. urbanum. MTT assay showed that the extracts of G. urbanum did not have any toxic effects on ADMSCs. Immunostaining results showed increase in the expression of α-actinin and cardiac troponin I (cTnI), and quantitative real-time reverse-transcription PCR data confirmed the upregulation of ACTN, ACTC1, and TNNI3 genes in ADMSCs after treatment. According to HPLC fingerprinting, some cardiogenic effects of G. urbanum extracts are probably due to ellagic and gallic acid derivatives. Our findings indicated that G. urbanum extracts effectively upregulated some essential cardiogenic markers, which confirmed the therapeutic role of this plant as a traditional cardiac medicine.

Abstract
Many Geum species are known to be rich in biologically active compounds and therefore could be a source of new natural products with pharmacological potential. The medicinal plant Geum urbanum L. is widespread in Bulgaria and has been used in folk medicine. In the present study, the methanol extracts of the roots and aerial parts of G. urbanum and their fractions (petroleum ether, ethyl acetate and n-butanol) were investigated for antibacterial and radical scavenging activity. The ethyl acetate and n-butanol fractions inhibited the growth of Gram-positive pathogenic and opportunistic bacteria from the genus Staphylococcus (MIC EtOAc: 0.078 mg/ml aerial and 0.156 mg/ml roots; MIC n-BuOH: 0.156 mg/ml aerial and 1.25 mg/ml roots) and the species Bacillus cereus stronger than the other extracts and fractions tested (MIC EtOAc: 0.078 mg/ml aerial and 0.156 mg/ml roots; MIC n-BuOH: 0.156 mg/ml aerial and 0.078 mg/ml roots), and showed corresponding radical scavenging activity (EtOAc: EC50 1.5 µg/ml aerial, 0.8 µg/ml roots; n-BuOH: 4.5 µg/ml aerial; 3.7 µg/ml roots). Additionally, their total phenolic content was quantified (% of dry EtOAc fractions of roots 61%, of arial parts 32%; of dry n-BuOH fractions of roots 16%, of arial parts 13%). Seven compounds were isolated and identified spectroscopically from the ethyl acetate extract. Two acetylated ellagic acid rhamnosides were found for the first time in the genus Geum and three others, tormentic acid, niga-ichigoside F1, and 3,3'-di-O-methylellagic acid-4-O-β-D-glucopyranoside, were newly detected for the species G. urbanum. Our results reveal that G. urbanum L. is a perspective medicinal plant and deserves further, more detailed studies.

Abstract
Background The replacement of lost cardiac tissues by regenerated myocardium would be a therapeutic ideal for myocardial infarction. The objective of this study was therefore to evaluate the ability of an active fraction that was isolated from Rosa laevigata Michx in therapeutic cardiomyogenesis in a myocardial infarction rat model. Methods The myocardial infarction animal model was induced by the permanent ligation of the left anterior descending coronary artery in rats. The active fraction, which improves the survival rate and prevents ischemic reperfusion damage, was used to test the therapeutic effect of this fraction on myocardial infarction. Results The oral administration of the active fraction for 4 weeks could progressively restore the decreased cardiac function due to myocardial infarction. The significantly improved cardiac function was probably attributed to the active fraction-induced myocardial regeneration, which replaced the lost cardiac tissues in the myocardial infarction animals. Conclusions The property of this active fraction appears to be entirely novel and may provide a potential therapeutic alternative for myocardial infarction.

Abstract
Chronic coronary heart disease (cCHD) is characterized by atherosclerosis, which progressively narrows the coronary artery lumen and impairs myocardial blood flow. Restoration of occluded coronary vessels with newly formed collaterals remains an ideal therapeutic approach due to the need for redirecting blood flow into the ischemic heart. In this study, we investigated the effect of an active fraction isolated from Geum joponicum (AFGJ) on angiogenesis in cCHD hearts. Our results demonstrated that AFGJ not only enhanced capillary tube formation of endothelial cells, but also promoted the growth of new coronary collaterals (at the diameter 0.021-0.21 mm) in the ischemic region of hearts in rat cCHD model. Our study also indicated that the growth of new collaterals in ischemic hearts resulted in improved functional recovery of the cCHD hearts as demonstrated by ECG and echocardiography analyses. These data suggest that AFGJ may provide a novel therapeutic method for effective treatment of cCHD.

Abstract
3-Phosphoinositide-dependent protein kinase-1 (PDK1) is involved in numerous cellular responses. In this study, we investigated the protective effects of PDK1 gene expression against hypoxic conditions in cultured rat CMCs (rCMCs) and in a rat myocardial infarction (MI) model using the lentiviral vector (LeV) system. LeV-PDK1 transfer effectively reduced the apoptotic cell death caused by hypoxic injury as compared to LeV-GFP transfer in rCMCs the expression of survival proteins increased in the LeV-PDK1 group, whereas apoptosis signaling decreased in the rCMCs and in infarcted hearts treated with LeV-PDK1. LeV-PDK1 transfer also reduced apoptosis and infarct size and attenuated myocardial wall thinning and ventricular remodeling in a rat MI model. These findings suggest that PDK1 has a protective role in the injured ischemic myocardium via overexpression of the cell survival pathway in CMCs. Hence PDK1 can be used as a treatment strategy for myocardial salvage inin hypoxic injury.

Abstract
An intra-myocardial injection of a cardiogenic factor (cardiogenin) was reported to induce myocardial regeneration of exogenous mesenchymal stem cell (MSCs) origin. In this study, replacement of the dangerous intra-myocardial injection with a safe method and whether the endogenous MSCs contribute to the cardiogenin-mediated myocardial regeneration were investigated. Bone marrow transplantation with labeled MSCs was performed in rats, which were subsequently subject to a permanent ligation of left anterior descending coronary artery one week after the transplantation. The rats were then treated with the cardiogenin through oral administration for 2 weeks. We not only demonstrated the substantial therapeutic effects of cardiogenin on myocardial infarction through an oral administration, but also provided direct evidences that the bone marrow derived endogenous MSCs are the major cellular source of the regenerating myocardium. Preliminary mechanistic studies suggested that miR-9 and its target E-cadherin may be required for intercalated disc formation.

Abstract
The potential to generate virtually any differentiated cell type from stem cells offers the possibility of creating new sources of cells for regenerative medicine. To realize this potential, it will be essential to control stem cell differentiation. Chinese herbal medicine is a major aspect of traditional Chinese medicine and is a rich source of unique chemicals. As such, individual herbs or extracts may play a role in the proliferation and differentiation of stem cells. In this review, we discuss some of the Chinese herbal medicines that are used to treat human diseases such as neuronal degenerative diseases, cardiovascular diseases, and osteoporosis. We also describe the relationship between Chinese herbal medicines and stem cell regulation.
