Preclinical And Clinical Studies

Cardiovascular diseases are the leading cause of morbidity and mortality worldwide. In recent years, researchers are attracted to the use of cell therapy based on stem cell and progenitor cells, which has been a promising strategy for cardiac repair after injury. However, conducted research using intracoronary or intramyocardial transplantation of various types of stem/progenitor cells as a cell suspension showed modest efficiency. This is due to the low degree of integration and cell survival after transplantation. To overcome these limitations, the concept of the use of multicellular spheroids modeling the natural microenvironment of cells has been proposed, which allows maintaining their viability and therapeutic properties. It is of great interest to use so-called cardial spheroids (cardiospheres) spontaneously forming three-dimensional structures under low-adhesive conditions, consisting of a heterogeneous population of myocardial progenitor cells and extracellular matrix proteins. This review presents data on methods for creating cardiospheres, directed regulation of their properties and reparative potential, as well as the results of preclinical and clinical studies on their use for the treatment of heart diseases.

Clinical trials using stem cell therapy for heart diseases have not reproduced the initial positive results obtained with animal models. This might be explained by a decreased regenerative capacity of stem cells collected from the patients. This work aimed at the simultaneous investigation of endothelial stem/progenitor cells (EPCs), mesenchymal stem/progenitor cells (MSCs), and hematopoietic stem/progenitor cells (HSCs) in sternal bone marrow samples of patients with ischemic or valvular heart disease, using flow cytometry and colony assays. The study included 36 patients referred for coronary artery bypass grafting or valve replacement surgery. A decreased frequency of stem cells was observed in both groups of patients. Left ventricular dysfunction, diabetes, and intermediate risk in EuroSCORE and SYNTAX score were associated with lower EPCs frequency, and the use of aspirin andβ-blockers correlated with a higher frequency of HSCs and EPCs, respectively. Most importantly, the distribution of frequencies in the three stem cell compartments showed independent patterns. The combined investigation of the three stem cell compartments in patients with cardiovascular diseases showed that they are independently affected by the disease, suggesting the investigation of prognostic factors that may be used to determine when autologous stem cells may be used in cell therapy.

Multidrug resistance infections are the main cause of failure in the pro-regenerative cell-mediated therapy of burn wounds. The collagen-based matrices for delivery of cells could be potential substrates to support bacterial growth and subsequent lysis of the collagen leading to a cell therapy loss. In this article, we report the development of a new generation of cell therapy formulations with the capacity to resist infections through the bactericidal effect of antimicrobial peptide dendrimers and the anti-virulence effect of anti-quorum sensing MvfR (PqsR) system compounds, which are incorporated into their formulation. Anti-quorum sensing compounds limit the pathogenicity and antibiotic tolerance of pathogenic bacteria involved in the burn wound infections, by inhibiting their virulence pathways. For the first time, we report a biological cell therapy dressing incorporating live progenitor cells, antimicrobial peptide dendrimers, and anti-MvfR compounds, which exhibit bactericidal and anti-virulence properties without compromising the viability of the progenitor cells.

Heart failure (HF) remains the major cause of morbidity and mortality in the world with an alarming rapid rise in heart diseases. Myocardial infarction (MI), depriving of blood flow to the heart muscle, causes myocardial necrosis and apoptosis resulting in decrease of myocardial quantity and ventricular remodeling, which is the main cause of HF. As mature cardiomyocytes (CMs) are incapable of differentiation and proliferation, cardiomyocytes damage is not likely to be reversed. Recent research has advanced to the point where damaged CMs or myocardium can be repaired by exogenous cells or artificial tissue. This review provides the most up-to-date information on the current status of cell therapy and tissue three-dimensional (3D) bioprinting for the treatment of HF. Requirements on 3D printing of biomaterials will be provided including biophysical properties, biocompatibility and biodegradable absorption in vivo that are key factors on the survival and proliferation of transplanted cells in the MI area. Also discussed are the current challenges in cell-based HF therapies and future perspectives in clinical applications.

New Perspective

Myocardial progenitor cells represent a perspective source for cell therapy of cardiovascular disorders and are intensively studied. However, mainly the cells from adult patients are studied whereas the cells derived from children with congenital heart diseases remained poorly investigated. The aim of the present work was to obtain progenitor cells from intraoperatively obtained cardiac tissue from infants and children undergoing repair of congenital cardiac defects. Following isolation, the cells gave rise to a clonogenic, highly proliferative spindle-shaped cell population. The cells expressed markers of cardiogenic origin and were shown to differentiate towards cardiogenic lineage. This resident myocardial progenitor cells obtained from infant myocardial tissue demonstrate similar characteristics to previously described cells derived from adult myocardial tissue. This study confirms the possibility of obtaining a pool of progenitor cells from tiny tissue fragments and opens a new perspective of using these cells in regenerative medicine and further research of congenital heart disease pathogenesis.

The scale of cardiac diseases, and in particular heart failure and acute myocardial infarction, emphasises the need for radically new approaches, such as cell therapy, to address the underlying cause of the disease, the loss of functional myocardium. Stem cell-based therapies, whether through transplanted cells or directing innate repair, may provide regenerative approaches to cardiac diseases by halting, or even reversing, the events responsible for progression of organ failure. Cardio3 BioSciences, a leading Belgian biotechnology company focused on the discovery and development of regenerative and protective therapies for the treatment of cardiac disease, was founded in this context in 2004. The company is developing a highly innovative cell therapy approach based on a platform designed to reprogramme the patient’s own stem cells into cardiac progenitor cells. The underlying rationale behind this approach is that, in order to reconstruct cardiac tissue, stem cells need to be specific to cardiac tissue. The key is therefore to provide cardiac-specific progenitor cells to the failing heart to induce cardiac repair.

Three Dimensional Echocardiography

Development of interventional methods has revolutionized the treatment of structural cardiac diseases. Given the complexity of structural interventions and the anatomical variability of various structural defects, novel imaging techniques have been implemented in the current clinical practice for guiding the interventional procedure and for selection of the device to be used. Three– dimensional echocardiography is the most used imaging method that has improved the threedimensional assessment of cardiac structures, and it has considerably reduced the cost of complications derived from malalignment of interventional devices. Assessment of cardiac structures with the use of angiography holds the advantage of providing images in real time, but it does not allow an anatomical description. Transesophageal Echocardiography (TEE) and intracardiac ultrasonography play major roles in guiding Atrial Septal Defect (ASD) or Patent Foramen Ovale (PFO) closure and device follow-up, while TEE is the procedure of choice to assess the flow in the Left Atrial Appendage (LAA) and the embolic risk associated with a decreased flow. On the other hand, contrast CT and MRI have high specificity for providing a detailed description of structure, but cannot assess the flow through the shunt or the valvular mobility. This review aims to present the role of modern imaging techniques in pre-procedural assessment and intraprocedural guiding of structural percutaneous interventions performed to close an ASD, a PFO, an LAA or a patent ductus arteriosus.

Renal Epithelial Cells

The tissue culture of multicellular spheroids from the renal epithelial cell line LLC-PK1 (proximal tubule) is described. This represents a biological system of intermediate complexity between renal tissue in vivo and simple monolayer cultures. The multicellular structures, which show many similarities to kidney tubules in vivo, including a vectorial water transport, should prove useful for studying the potential nephrotoxicity of drugs and chemicals in vitro. In addition, the propagation of renal epithelial cells as multicellular spheroids in serum-free culture may provide information on the release of specific biological parameters, which may be suppressed or masked in serum-supplemented media.

AbstractHeart diseases remain the top threat to human health, and the treatment of heart diseases changes with each passing day. Convincing evidence shows that three-dimensional (3D) printing allows for a more precise understanding of the complex anatomy associated with various heart diseases. In addition, 3D-printed models of cardiac diseases may serve as effective educational tools and for hands-on simulation of surgical interventions. We introduce examples of the clinical applications of different types of 3D printing based on specific cases and clinical application scenarios of 3D printing in treating heart diseases. We also discuss the limitations and clinically unmet needs of 3D printing in this context.
