Abstract
Conventional two-dimensional (2-D) cultivation are easy to utilize for human pluripotent stem (hPS) cell cultivation in standard techniques and are important for analysis or development of the signal pathways to keep pluripotent state of hPS cells cultivated on 2-D cell culture materials. However, the most efficient protocol to prepare hPS cells is the cell culture in a three dimensional (3-D) cultivation unit because huge numbers of hPS cells should be utilized in clinical treatment. Some 3-D cultivation strategies for hPS cells are considered: (a) microencapsulated cell cultivation in suspended hydrogels, (b) cell cultivation on microcarriers (MCs), (c) cell cultivation on self-aggregated spheroid [cell aggregates; embryoid bodies (EBs) and organoids], (d) cell cultivation on microfibers or nanofibers, and (e) cell cultivation in macroporous scaffolds. These cultivation ways are described in this chapter.

Abstract
Myocardial infarction (MI) irreversibly injures the heart tissue. Cardiovascular tissue engineering has been developed as a promising therapeutic approach for post-MI repair. Previously, we discovered the ability of a polypyrrole (PPy)-incorporated cardiogel (CG) for improvement of maturity and functional synchrony of rat neonatal cardiomyocytes. Here, we used the cross-linked form of PPy-incorporated CG (CG-PPy), in order to improve electromechanical properties of scaffold, for application in cardiac progenitor cell (CPC) transplantation on post-MI rat hearts. Improved mechanical property and electrical conductivity (sixfold) were evident in the cross-linked CG-PPy (P1) compared to cross-linked CG (C1) scaffolds. Transplantation of CPC-loaded P1 (P1-CPC) resulted in substantial improvement of cardiac functional properties. Furthermore, lower fibrotic tissue and higher CPC retention were observed. The grafted cells showed cardiomyocyte characteristics when stained with human cardiac troponin T and connexin43 antibodies, while neovessel formation was similarly prominent. These findings highlight the therapeutic promise of the P1 scaffold as a CPC carrier for functional restoration of the heart post-MI.

Abstract
Objective Sexual dimorphism in mammals can be described as subsequent transcriptional differences from their distinct sex chromosome complements. Following X inactivation in females, the Y chromosome is the major genetic difference between sexes. In this study, we used a male embryonic stem cell line (Royan H6) to identify the potential role of the male-specific region of the Y chromosome (MSY) during spontaneous differentiation into embryoid bodies (EBs) as a model of early embryonic development. Materials and Methods In this experimental study, RH6 cells were cultured on inactivated feeder layers and Matrigel. In a dynamic suspension system, aggregates were generated in the same size and were spontaneously differentiated into EBs. During differentiation, expression patterns of specific markers for three germ layers were compared with MSY genes. Results Spontaneous differentiation was determined by downregulation of pluripotent markers and upregulation of fourteen differentiation markers. Upregulation of the ectoderm markers was observed on days 4 and 16, whereas mesoderm markers were upregulated on the 8th day and endodermic markers on days 12-16. Mesoderm markers correlated with 8 MSY genes namely DDX3Y, RPS4Y1, KDM5D, TBL1Y, BCORP1, PRY, DAZ, and AMELY, which were classified as a mesoderm cluster. Endoderm markers were co-expressed with 7 MSY genes, i.e. ZFY, TSPY, PRORY, VCY, EIF1AY, USP9Y, and RPKY, which were grouped as an endoderm cluster. Finally, the ectoderm markers correlated with TXLNGY, NLGN4Y, PCDH11Y, TMSB4Y, UTY, RBMY1, and HSFY genes of the MSY, which were categorized as an ectoderm cluster. In contrast, 2 MSY genes, SRY and TGIF2LY, were more highly expressed in RH6 cells compared to EBs. Conclusion We found a significant correlation between spontaneous differentiation and upregulation of specific MSY genes. The expression alterations of MSY genes implied the potential responsibility of their gene co-expression clusters for EB differentiation. We suggest that these genes may play important roles in early embryonic development.

Abstract
Cell-based therapy (CBT) is attracting much attention to treat incurable diseases. In recent years, several clinical trials have been conducted using human pluripotent stem cells (hPSCs), and other potential therapeutic cells. Various private- and government-funded organizations are investing in finding permanent cures for diseases that are difficult or expensive to treat over a lifespan, such as age-related macular degeneration, Parkinson’s disease, or diabetes, etc. Clinical-grade cell manufacturing requiring current good manufacturing practices (cGMP) has therefore become an important issue to make safe and effective CBT products. Current cell production practices are adopted from conventional antibody or protein production in the pharmaceutical industry, wherein cells are used as a vector to produce the desired products. With CBT, however, the “cells are the final products” and sensitive to physico- chemical parameters and storage conditions anywhere between isolation and patient administration. In addition, the manufacturing of cellular products involves multi-stage processing, including cell isolation, genetic modification, PSC derivation, expansion, differentiation, purification, characterization, cryopreservation, etc. Posing a high risk of product contamination, these can be time- and cost- prohibitive due to maintenance of cGMP. The growing demand of CBT needs integrated manufacturing systems that can provide a more simple and cost-effective platform. Here, we discuss the current methods and limitations of CBT, based upon experience with biologics production. We review current cell manufacturing integration, automation and provide an overview of some important considerations and best cGMP practices. Finally, we propose how multi-stage cell processing can be integrated into a single bioreactor, in order to develop streamlined cGMP-compliant cell processing systems.

Abstract
Cardiac arrhythmia is an irregular heart rhythm that can lead to serious heart conditions and various organ disorders, and may cause sudden cardiac death. Catalpol belongs to the iridoid glycoside family and is highly abundant in Rehmannia glutinosa Libosch. The study included five groups such as group I (normal control), group II (treatment control), group III (low-dose treatment), group IV (medium-dose treatment) and group V (high-dose treatment). We investigated the therapeutic effects of catalpol on cardiac arrhythmia in human-induced pluripotent stem cells (iPSCs). Cell viability, lactate dehydrogenase (LDH) levels, lipid peroxidation, antioxidant activity, and caspase-3 and caspase-9 activities and protein levels were measured in normal control, treatment control, and treated (1, 10, and 100 µM) iPSC groups. Compared with the treatment control group, catalpol supplementation (1, 10, and 100 µM) increased iPSC cell viability by 7.5, 27.3, and 65.8%, respectively; reduced the LDH levels by 10.4, 31.3, and 75.2%, respectively; and reduced the lipid peroxidation levels by 7.7, 33.0, and 62.6%, respectively. The antioxidant levels were significantly higher in the treatment control group than in the normal control group. Catalpol (100 µM) reduced the caspase-3 and caspase-9 activities by more than 30% and increased expression of the corresponding proteins by more than 50%. These findings suggest that the naturally occurring iridoid glycoside catalpol is effective against aconitine-induced cardiac arrhythmia in iPSCs.

Abstract
Myocardial infarction (MI) is a life-threatening disease resulting from irreversible death of cardiomyocytes (CMs) and weakening of the heart blood-pumping function. Stem cell-based therapies have been studied for MI treatment over the last two decades with promising outcome. In this review, we critically summarize the past work in this field to elucidate the advantages and disadvantages of treating MI using pluripotent stem cells (PSCs) including both embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), adult stem cells, and cardiac progenitor cells. The main advantage of the latter is their cytokine production capability to modulate immune responses and control the progression of healing. However, human adult stem cells have very limited (if not 'no') capacity to differentiate into functional CMs in vitro or in vivo. In contrast, PSCs can be differentiated into functional CMs although the protocols for the cardiac differentiation of PSCs are mainly for adherent cells under 2D culture. Derivation of PSC-CMs in 3D, allowing for large-scale production of CMs via modulation of the Wnt/β-catenin signal pathway with defined chemicals and medium, may be desired for clinical translation. Furthermore, the technology of purification and maturation of the PSC-CMs may need further improvements to eliminate teratoma formation after in vivo implantation of the PSC-CMs for treating MI. In addition, in vitro derived PSC-CMs may have mechanical and electrical mismatch with the patient's cardiac tissue, which causes arrhythmia. This supports the use of PSC-derived cells committed to cardiac lineage without beating for implantation to treat MI. In this case, the PSC derived cells may utilize the mechanical, electrical, and chemical cues in the heart to further differentiate into mature/functional CMs in situ. Another major challenge facing stem cell therapy of MI is the low retention/survival of stem cells or their derivatives (e.g., PSC-CMs) in the heart for MI treatment after injection in vivo. This may be resolved by using biomaterials to engineer stem cells for reduced immunogenicity, immobilization of the cells in the heart, and increased integration with the host cardiac tissue. Biomaterials have also been applied in the derivation of CMs in vitro to increase the efficiency and maturation of differentiation. Collectively, a lot has been learned from the past failure of simply injecting intact stem cells or their derivatives in vivo for treating MI, and bioengineering stem cells with biomaterials is expected to be a valuable strategy for advancing stem cell therapy towards its widespread application for treating MI in the clinic.

Abstract
Cardiovascular progenitor cells (CPCs) derived from human pluripotent stem cells (hPSCs) are proposed to be invaluable cell sources for experimental and clinical studies. This wide range of applications necessitates large-scale production of CPCs in an in vitro culture system, which enables both expansion and maintenance of these cells. In this study, we aimed to develop a defined and efficient culture medium that uses signaling factors for large-scale expansion of early CPCs, called cardiogenic mesodermal cells (CMCs), which were derived from hPSCs. Chemical screening resulted in a medium that contained a reproducible combination of three factors (A83-01, bFGF, and CHIR99021) that generated 1014 CMCs after 10 passages without the propensity for tumorigenicity. Expanded CMCs retained their gene expression pattern, chromosomal stability, and differentiation tendency through several passages and showed both the safety and possible cardio-protective potentials when transplanted into the infarcted rat myocardium. These CMCs were efficiently cryopreserved for an extended period of time. This culture medium could be used for both adherent and suspension culture conditions, for which the latter is required for large-scale CMC production. Taken together, hPSC-derived CMCs exhibited self-renewal capacity in our simple, reproducible, and defined medium. These cells might ultimately be potential, promising cell sources for cardiovascular studies.

Abstract
OBJECTIVE Human embryonic stem cells (hESCs) have the potential to give rise to all types of cells in the human body when appropriately induced to differentiate. Stem cells can differentiate spontaneously into the three-germ layer derivatives by embryoid bodies (EBs) formation. However, the two-dimensional (2D) adherent culture of hESCs under defined conditions is commonly used for directed differentiation toward a specific type of mature cells. In this study, we aimed to determine the propensity of the Royan hESC lines based on comparison of expression levels of 46 lineage specific markers. MATERIALS AND METHODS In this experimental study, we have compared the expression of lineage-specific markers in hESC lines during EB versus adherent-based spontaneous differentiation. We used quantitative real-time polymerase chain reaction (qRT-PCR) to assess expressions of 46 lineage-specific markers in 4 hESC lines, Royan H1 (RH1), RH2, RH5, and RH6, during spontaneous differentiation in both EB and adherent cultures at 0, 10, and 30 days after initiation of differentiation. RESULTS Based on qRT-PCR data analysis, the liver and neuronal markers had higher expression levels in EBs, whereas skin-specific markers expressed at higher levels in the adherent culture. The results showed differential expression patterns of some lineage-specific markers in EBs compared with the adherent cultures. CONCLUSION According to these results, possibly the spontaneous differentiation technique could be a useful method for optimization of culture conditions to differentiate stem cells into specific cell types such ectoderm, neuron, endoderm and hepatocyte. This approach might prove beneficial for further work on maximizing the efficiency of directed differentiation and development of novel differentiation protocols.

Abstract
Bone marrow stromal cells (BMSCs) are a unique population of multipotent cells that exhibit pluripotent properties to a certain extent and are significantly heterogeneous in terms of the cell population. We isolate a small cell subpopulation from bovine BMSCs, bovine small stem cells (bSSCs), and herein characterize their properties. The bSSCs are smaller in size and express nuclear Oct-4 and other pluripotency markers. In addition, when cultured in suspension conditions, bSSCs form three-dimensional spheres and display a strong capability for self-renewal and differentiation into cells from three germ layers. Notably, bSSCs display neural features with Sox1 and Pax6 expression. Using bSSCs as donor nuclear cells for somatic cell nuclear transfer, we further demonstrate that the developmental potential of cloned embryos in vitro is significantly increased. Our study identifies a new bovine bone marrow stromal cell-derived stem cell subtype that could have broad importance for developmental biology as well as great potential for regenerative medicine.

Abstract
The number of high-quality cells required for engineering an adult human-sized bioartificial organ is greater than one billion. Until the emergence of induced pluripotent stem cells (iPSCs), autologous cell sources of this magnitude and with the required complexity were not available. Growing this number of cells in a traditional 2D cell culture system requires extensive time, resources, and effort and does not always meet clinical requirements. The use of a closed cell culture system is an efficient and clinically applicable method that can be used to expand cells under controlled conditions. We aimed to use the Quantum Cell Expansion System (QES) as an iPSC monolayer-based expansion system. Human iPSCs were expanded (up to 14-fold) using the QES on two different coatings (laminin 521 (LN521) and vitronectin (VN)), and a karyotype analysis was performed. The cells were characterized for spontaneous differentiation and pluripotency by RT-PCR and flow cytometry. Our results demonstrated that the QES provides the necessary environment for exponential iPSC growth, reaching 689.75 × 106 ± 86.88 × 106 in less than 7 days using the LN521 coating with a population doubling level of 3.80 ± 0.19. The same result was not observed when VN was used as a coating. The cells maintained normal karyotype (46-XX), expressed pluripotency markers (OCT4, NANOG, LIN28, SOX2, REX1, DPPA4, NODAL, TDGFb, TERT3, and GDF), and expressed high levels of OCT4, SOX2, NANOG, SSEA4, TRA1-60, and TRA1-81. Spontaneous differentiation into ectoderm (NESTIN, TUBB3, and NEFH), mesoderm (MSX1, BMP4, and T), and endoderm (GATA6, AFP, and SOX17) lineages was detected by RT-PCR with both coating systems. We conclude that the QES maintains the stemness of iPSCs and is a promising platform to provide the number of cells necessary to recellularize small human-sized organ scaffolds for clinical purposes.

Abstract
In recent years, human pluripotent stem (hPS) cells have started to emerge as a potential tool with application in fields such as regenerative medicine, disease modeling, and drug screening. In particular, the ability to differentiate human-induced pluripotent stem (hiPS) cells into different cell types and to mimic structures and functions of a specific target organ, resourcing to organoid technology, has introduced novel model systems for disease recapitulation while offering a powerful tool to provide a faster and reproducible approach in the process of drug discovery. All these technologies are expected to improve the overall quality of life of the humankind. Here, we highlight the main applications of hiPS cells and the main challenges associated with the translation of hPS cell derivatives into clinical settings and other biomedical applications, such as the costs of the process and the ability to mimic the complexity of the in vivo systems. Moreover, we focus on the bioprocessing approaches that can be applied towards the production of high numbers of cells as well as their efficient differentiation into the final product and further purification.

Abstract
Objective Cardiovascular progenitor cells (CPCs) are introduced as one of the promising cell sources for preclinical studies
and regenerative medicine. One of the earliest type of CPCs is cardiogenic mesoderm cells (CMCs), which have the capability
to generate all types of cardiac lineage derivatives. In order to benefit from CMCs, development of an efficient culture strategy
is required. We aim to explore an optimized culture condition that uses human embryonic stem cell (hESC)-derived CMCs.
Materials and Methods In this experimental study, hESCs were expanded and induced toward cardiac lineage in a
suspension culture. Mesoderm posterior 1-positive (MESP1+) CMCs were subjected to four different culture conditions: i.
Suspension culture of CMC spheroids, ii. Adherent culture of CMC spheroids, iii. Adherent culture of single CMCs using
gelatin, and iv. Adherent culture of single CMCs using Matrigel.
Results Although, we observed no substantial changes in the percentage of MESP1+ cells in different culture
conditions, there were significantly higher viability and total cell numbers in CMCs cultured on Matrigel (condition iv)
compared to the other groups. CMCs cultivated on Matrigel maintained their progenitor cell signature, which included
the tendency for cardiogenic differentiation.
Conclusion These results showed the efficacy of an adherent culture on Matrigel for hESC-derived CMCs, which would
facilitate their use for future applications.

Human cardiomyocytes undergo enhanced maturation in embryonic stem cell-derived organoid transplants. Biomaterials 2018; 192:537-550.

Abstract
Human cardiomyocytes (CM) differentiated from pluripotent stem cells (PSCs) are relatively immature when generated in two-dimensional (2D) in vitro cultures, which limits their biomedical applications. Here, we devised a strategy to enhance maturation of human CM in vitro by assembly of three-dimensional (3D) cardiac organoids (CO) containing human embryonic stem cell-derived cardiac progenitor cells (hESC-CPCs), endothelial cells (ECs), and mesenchymal stem cells (MSCs). In contrast to corresponding 2D cultures, 3D CO not only developed into structures containing spontaneously beating CM, but also showed enhanced maturity as indicated by increased expressions of sarcomere and ion channel genes and reduced proliferation. Heterotopic implantation of CO into the peritoneal cavity of immunodeficient mice induced neovascularization, and further stimulated upregulation of genes coding for the contractile apparatus, Ca2+ handling and ion channel proteins. In addition, CM in implanted CO were characterized by a more mature ultrastructure compared to CM implanted without CO support. Functional analysis revealed the presence of working cardiomyocytes in both in vivo and ex ovo chorioallantoic membrane implanted CO. Our results demonstrate that cultivation in 3D CO and subsequent heterotopic implantation enhance maturation of CM towards an adult-like phenotype. We reason that CO-derived CM represent an attractive source for drug discovery and other biomedical applications.

Abstract
Organoids can be regarded as a beneficial tool for discovery of new therapeutics for diabetes and/or maturation of pancreatic progenitors (PP) towards β cells. Here, we devised a strategy to enhance maturation of PP by assembly of three-dimensional (3D) pancreatic organoids (PO) containing human embryonic stem (ES) cell derivatives including ES-derived pancreatic duodenal homeobox 1 (PDX1) + early PP, mesenchymal stem cells, and endothelial cells at an optimized cell ratio, on Matrigel. The PO was placed in a 3D-printed tissue trapper and heterotopically implanted into the peritoneal cavity of immunodeficient mice where it remained for 90 days. Our results indicated that, in contrast to corresponding early PP transplants, 3D PO developed more vascularization as indicated by greater area and number of vessels, a higher number of insulin-positive cells and improvement of human C-peptide secretions. Based on our findings, PO-derived β cells could be considered a novel strategy to study human β-cell development, novel therapeutics, and regenerative medicine for diabetes.

Abstract
Cardiac arrhythmias are major life-threatening conditions. The landmark discovery of induced pluripotent stem cells has provided a promising in vitro system for modeling hereditary cardiac arrhythmias as well as drug development and toxicity testing. Nowadays, nutraceuticals are frequently used as supplements for cardiovascular therapy. Here we studied the cardiac effects of hawthorn ( Crataegus pentagyna) leaf extract using cardiomyocytes (CMs) differentiated from healthy human embryonic stem cells, long QT syndrome type 2 (LQTS2), and catecholaminergic polymorphic ventricular tachycardia type 1 (CPVT1) patient-specific induced pluripotent stem cells. The hydroalcoholic extract resulted in a dose-dependent negative chronotropic effect in all CM preparations leading to a significant reduction at 1000 µg/ml. This was accompanied by prolongation of field potential durations, although with different magnitudes in CMs from different human embryonic stem cell and iPSC lines. Hawthorn further prolonged field potential durations in LQTS2 CMs but reduced the beating frequencies and occurrence of immature field potentials triggered by β1-adrenergic stimulation in CPVT1 CMs at 300 and 1000 µg/ml. Furthermore, isoquercetin and vitexin flavonoids significantly slowed down isoproterenol (5 µM)-induced beating frequencies at 3 and 10 µg/ml. Therefore, C. pentagyna leaf extract and its isoquercetin and vitexin flavonoids may be introduced as a novel nutraceutical with antiarrhythmic potential for CPVT1 patients.-Pahlavan, S., Tousi, M.

Abstract
Despite evidence for sex-specific cardiovascular physiology and pathophysiology, the biological basis for this dimorphism remains to be explored. Apart from hormonal factors, gender-related characteristics may reside in the function of sex chromosomes during cardiac development. In this study, we investigated the differential expression of the male-specific region of the Y chromosome (MSY) genes and their X counterparts during cardiac differentiation of human embryonic stem cells (hESC). We observed alterations in mRNA and protein levels of TBL1Y, PCDH11Y, ZFY, KDM5D, USP9Y, RPS4Y1, DDX3Y, PRY, XKRY, BCORP1, RBMY, HSFY, and UTY, which accompanied changes in intracellular localization. Of them, the abundance of a Y chromosome missing protein, TBL1Y, showed a significant increase during differentiation while the expression level of its X counterpart decreased. Consistently, reducing TBL1Y cellular level using siRNA approach influenced cardiac differentiation by reducing its efficacy as well as increasing the probability of impaired contractions. TBL1Y knockdown may have negatively impacted cardiogenesis by CtBP stabilization. Furthermore, we presented compelling experimental evidence to distinguish TBL1Y from TBL1X, its highly similar X chromosome homologue, and proposed reclassification of TBL1Y as "found missing protein" (PE1). Our results demonstrated that MSY proteins may play an important role in cardiac development.

Abstract
Stem cells and other functionally defined therapeutic cells (e.g., T cells) are promising to bring hope of a permanent cure for diseases and disorders that currently cannot be cured by conventional drugs or biological molecules. This paradigm shift in modern medicine of using cells as novel therapeutics can be realized only if suitable manufacturing technologies for large-scale, cost-effective, reproducible production of high-quality cells can be developed. Here we review the state of the art in therapeutic cell manufacturing, including cell purification and isolation, activation and differentiation, genetic modification, expansion, packaging, and preservation. We identify current challenges and discuss opportunities to overcome them such that cell therapies become highly effective, safe, and predictively reproducible while at the same time becoming affordable and widely available.

Abstract
OBJECTIVE The properties of self-renewal and division in spermatogonial stem cells (SSCs) support spermatogenesis. There is a number of reported methods for in vitro SSC culture systems. The development of a culture system that effectively supports isolation and selfrenewal of germline stem cells (GSCs) is of tremendous benefit for clinical trials, experimental research, and as potential treatment for male infertility. The current study aims to consider the cultivation and behavior of GSCs in a non-adherent culture system. MATERIALS AND METHODS In this experimental study, we cultured testicular cells from neonatal mice in agarose coated plates in the presence of Dulbecco's modified Eagle's medium (DMEM) medium (CTRL group), 10% fetal bovine serum (FBS)+DMEM (10% group), and growth factor (G group) that contained 2% FBS, glial cell-derived neurotrophic factor (GDNF), epidermal growth factor (EGF), and fibroblast growth factor (FGF). Mouse spermatogonial stem-like colonies were isolated approximately 3 weeks after digestion of the testis tissue. After passages 2-3, the identity of the mouse spermatogonial stem-like cells was confirmed by immunocytochemistry, reverse transcription-polymerase chain reaction (RT-PCR), and flow cytometry against the germ cell markers α6, β1, c-Kit, Thy-1, c-Ret, Plzf, and Oct4. The statistical significance between mean values in different groups was determined by one-way analysis of variance (ANOVA). RESULTS We observed spermatogonial stem-like colonies in the G and 10% groups, but not the CTRL group. Immunocytochemistry, flow cytometry, and RT-PCR confirmed expressions of germ cell markers in these cells. In the spermatogonial stem-like cells, we observed a significant expression (P<0.05) of germ cell markers in the G and 10% groups versus the testis cells (T). Their proliferative and apoptotic activities were examined by Ki67 and PI/annexin V-FITC. Alkaline phosphatase assay showed that mouse spermato- gonial stem-like colonies were partially positive. CONCLUSION A non-adherent culture system could provide a favorable method for in vitro short-term culture of spermatogonial stem-like cell colonies.

Abstract
Maximizing the benefit of human pluripotent stem cells (hPSCs) for research, disease modeling, pharmaceutical and clinical applications requires robust methods for the large-scale production of functional cell types, including cardiomyocytes. Here we demonstrate that the temporal manipulation of WNT, TGF-β, and SHH signaling pathways leads to highly efficient cardiomyocyte differentiation of single-cell passaged hPSC lines in both static suspension and stirred suspension bioreactor systems. Employing this strategy resulted in ~ 100% beating spheroids, consistently containing > 80% cardiac troponin T-positive cells after 15 days of culture, validated in multiple hPSC lines. We also report on a variation of this protocol for use with cell lines not currently adapted to single-cell passaging, the success of which has been verified in 42 hPSC lines. Cardiomyocytes generated using these protocols express lineage-specific markers and show expected electrophysiological functionalities. Our protocol presents a simple, efficient and robust platform for the large-scale production of human cardiomyocytes.

Abstract
The human heart is considered a non-regenerative organ. Worldwide, cardiovascular diseases continue to be the leading cause of death. Despite advances in cardiac treatment, myocardial repair remains severely limited by the lack of an appropriate source of viable cardiomyocytes (CMs) to replace damaged tissue. Human pluripotent stem cells (hPSCs), embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) can efficiently be differentiated into functional CMs necessary for cell replacement therapy and other potential applications. The number of protocols that derive CMs from hPSCs has increased exponentially over the past decade following observation of the first human beating CMs. A number of highly efficient, chemical based protocols have been developed to generate human CMs (hCMs) in small-scale and large-scale suspension systems. To reduce the heterogeneity of hPSC-derived CMs, the differentiation protocols were modulated to exclusively generate atrial-, ventricular-, and nodal-like CM subtypes. Recently, remarkable advances have been achieved in hCM generation including chemical-based cardiac differentiation, cardiac subtype specification, large-scale suspension culture differentiation, and development of chemically defined culture conditions. These hCMs could be useful particularly in the context of in vitro disease modeling, pharmaceutical screening and in cellular replacement therapies once the safety issues are overcome. Herein we review recent progress in the in vitro generation of CMs and cardiac subtypes from hPSCs and discuss their potential applications and current limitations.

A Universal and Robust Integrated Platform for the Scalable Production of Human Cardiomyocytes From Pluripotent Stem Cells. Stem Cells Transl Med 2015; 4:1482-94.

Abstract
UNLABELLED Recent advances in the generation of cardiomyocytes (CMs) from human pluripotent stem cells (hPSCs), in conjunction with the promising outcomes from preclinical and clinical studies, have raised new hopes for cardiac cell therapy. We report the development of a scalable, robust, and integrated differentiation platform for large-scale production of hPSC-CM aggregates in a stirred suspension bioreactor as a single-unit operation. Precise modulation of the differentiation process by small molecule activation of WNT signaling, followed by inactivation of transforming growth factor-β and WNT signaling and activation of sonic hedgehog signaling in hPSCs as size-controlled aggregates led to the generation of approximately 100% beating CM spheroids containing virtually pure (∼90%) CMs in 10 days. Moreover, the developed differentiation strategy was universal, as demonstrated by testing multiple hPSC lines (5 human embryonic stem cell and 4 human inducible PSC lines) without cell sorting or selection. The produced hPSC-CMs successfully expressed canonical lineage-specific markers and showed high functionality, as demonstrated by microelectrode array and electrophysiology tests. This robust and universal platform could become a valuable tool for the mass production of functional hPSC-CMs as a prerequisite for realizing their promising potential for therapeutic and industrial applications, including drug discovery and toxicity assays. SIGNIFICANCE Recent advances in the generation of cardiomyocytes (CMs) from human pluripotent stem cells (hPSCs) and the development of novel cell therapy strategies using hPSC-CMs (e.g., cardiac patches) in conjunction with promising preclinical and clinical studies, have raised new hopes for patients with end-stage cardiovascular disease, which remains the leading cause of morbidity and mortality globally. In this study, a simplified, scalable, robust, and integrated differentiation platform was developed to generate clinical grade hPSC-CMs as cell aggregates under chemically defined culture conditions. This approach resulted in approximately 100% beating CM spheroids with virtually pure (∼90%) functional cardiomyocytes in 10 days from multiple hPSC lines. This universal and robust bioprocessing platform can provide sufficient numbers of hPSC-CMs for companies developing regenerative medicine technologies to rescue, replace, and help repair damaged heart tissues and for pharmaceutical companies developing advanced biologics and drugs for regeneration of lost heart tissue using high-throughput technologies. It is believed that this technology can expedite clinical progress in these areas to achieve a meaningful impact on improving clinical outcomes, cost of care, and quality of life for those patients disabled and experiencing heart disease.

Abstract
Objective There is constant difficulty in obtaining adequate supplies of blood components, as well as disappointing performance of "universal" red blood cells. Advances in
somatic cell reprogramming of human-induced pluripotent stem cells (hiPSCs) have provided a valuable alternative source to differentiate into any desired cell type as a therapeutic promise to cure many human disease.
Materials and Methods In this experimental study, we examined the erythroid differentiation potential of normal Bombay hiPSCs (B-hiPSCs) and compared results
to human embryonic stem cell (hESC) lines. Because of lacking ABO blood group
expression in B-hiPSCs, it has been highlighted as a valuable source to produce any
cell type in vitro.
Results Similar to hESC lines, hemangioblasts derived from B-hiPSCs expressed approximately 9% KDR+CD31+ and approximately 5% CD31+CD34+. In semisolid media,
iPSC and hESC-derived hemangioblast formed mixed type of hematopoietic colony. In
mixed colonies, erythroid progenitors were capable to express CD71+GPA+HbF+ and accompanied by endothelial cells differentiation. Conclusion Finally, iPS and ES cells have been directly induced to erythropoiesis without hemangioblast formation that produced CD71+HbF+ erythroid cells. Although we observed
some variations in the efficiency of hematopoietic differentiation between iPSC and ES cells,
the pattern of differentiation was similar among all three tested lines.

Abstract
The envisioned clinical and industrial use of human pluripotent stem cells and their derivatives has given major momentum to the establishment of suspension culture protocols that enable the mass production of cells. Understanding molecular changes accompanying the transfer from adherent to suspension culture is of utmost importance because this information can have a direct effect on the development of optimized culture conditions. In this study we assessed the gene expression of human embryonic stem cells and induced pluripotent stem cells grown in surface-adherent culture (two-dimensional) versus free-floating suspension culture spheroids (three-dimensional). We combined a quantitative proteomic approach based on stable isotope labeling by amino acids in cell culture with deep-sequencing-based transcriptomics. Cells in three-dimensional culture showed reduced expression of proteins forming structural components of cell-cell and cell-extracellular matrix junctions. However, fully unexpected, we found up-regulation of secreted inhibitors of the canonical Wnt signaling pathway and, concomitantly, a reduction in the level of active β-catenin and in the expression of Wnt target genes. In Western blot analyses the cysteine protease calpain was shown to cleave E-cadherin and β-catenin under three-dimensional culture conditions. Our data allowed the development of a model in which calpain cleavage of E-cadherin induces the disintegration of focal cell contacts and generates a 100-kDa E-cadherin fragment required for the formation of three-dimensional cell-cell contacts in spheroids. The parallel release of β-catenin and its potential activation by calpain cleavage are counterbalanced by the overexpression of soluble Wnt pathway inhibitors. According to this model, calpain has a key function in the interplay between E-cadherin and β-catenin-mediated intercellular adhesion and the canonical Wnt signaling pathway. Supporting this model, we show that pharmacological modulation of calpain activity prevents spheroid formation and causes disassembly of preexisting spheroids into single cells, thereby providing novel strategies for improving suspension culture conditions for human pluripotent stem cells in the future.

Abstract
Suspension cell culture systems with superior scalability, controllability, and monitoring options are an attractive alternative to static adherent culture methods for expansion and production of human pluripotent stem cells (hPSCs), including embryonic stem cells (ESCs) and induced pluripotent cells (iPSCs). In this chapter, we describe a scalable suspension culture system using serum-free, feeder-free, matrix-free, and defined culture conditions with spinner flasks for hPSC maintenance and expansion. This suspension culture system provides an efficient and GMP-compatible process for large-scale manufacture of hPSCs.

Abstract
Given the potential importance of human pluripotent stem cells (hPSCs) in translational research and regenerative medicine, the aim of the present study was to develop a simple, safe, and cost-effective substrate to expand hPSCs. We report the development of an extracellular matrix (ECM), designated "RoGel," based on conditioned medium (CM) of human fibroblasts under serum- and xeno-free culture conditions. The long-term self-renewal of hPSCs on RoGel was also assessed. The results showed that self-renewal, pluripotency, plating efficiency, and cloning efficiency of hPSCs on this newly developed ECM were similar to those of Matrigel, the conventional mouse-cell line-derived ECM. The cells had the capability to passage mechanically on a cold surface, which resulted in their long-term maintenance with normal karyotype. We have demonstrated that CM-coated plates preserved for 1 year at room temperature maintained the capability of hPSC expansion. This ECM provides an attractive hPSC culture platform for both research and future therapeutic applications.

Abstract
Recent technological advances in the generation, characterization, and bioprocessing of human pluripotent stem cells (hPSCs) have created new hope for their use as a source for production of cell-based therapeutic products. To date, a few clinical trials that have used therapeutic cells derived from hESCs have been approved by the Food and Drug Administration (FDA), but numerous new hPSC-based cell therapy products are under various stages of development in cell therapy-specialized companies and their future market is estimated to be very promising. However, the multitude of critical challenges regarding different aspects of hPSC-based therapeutic product manufacturing and their therapies have made progress for the introduction of new products and clinical applications very slow. These challenges include scientific, technological, clinical, policy, and financial aspects. The technological aspects of manufacturing hPSC-based therapeutic products for allogeneic and autologous cell therapies according to good manufacturing practice (cGMP) quality requirements is one of the most important challenging and emerging topics in the development of new hPSCs for clinical use. In this review, we describe main critical challenges and highlight a series of technological advances in all aspects of hPSC-based therapeutic product manufacturing including clinical grade cell line development, large-scale banking, upstream processing, downstream processing, and quality assessment of final cell therapeutic products that have brought hPSCs closer to clinical application and commercial cGMP manufacturing.

Abstract
Large quantities of human pluripotent stem cells (hPSCs) needed for therapeutic applications can be grown in scalable suspended microcarrier cultures. These microcarriers are coated with animal or human extracellular matrix (ECM) proteins to promote cell growth and maintain pluripotency. However, the coating is costly for large-scale cultures and it presents safety risks. This study demonstrates that hPSCs can be propagated on noncoated positively charged cellulose microcarriers in a serum-free medium containing the ROCK inhibitor, (Y27632) or myosin inhibitor, Blebbistatin. In the presence of these two inhibitors, myosin phosphatase 1 and myosin light chain 2 were dephosphorylated suggesting that reduced myosin contractility is responsible for hPSC survival and growth on ECM coating-free microcarriers. Cells propagated on the noncoated microcarriers for 12 passages maintained their pluripotency and karyotype stability. Scalability was demonstrated by achieving a cell concentration of 2.3×10⁶ cells/mL with 11.5-fold expansion (HES-3) in a 100-mL spinner flask. The differentiation capability of these cells toward three primary lineages is demonstrated via in vitro embryoid bodies and in vivo teratoma formations. Moreover, the directed differentiation to polysialylated neuronal cell adhesion molecule-positive (PSA-NCAM+) neural progenitors produced high cell concentrations (9.1±1.2×10⁶ cells/mL) with a cell yield of 412±77 neural progenitor cells per seeded HES-3 and a PSA-NCAM expression level of 91±1.1%. This defined serum- and coating-free scalable microcarrier culturing system is a safer and less expensive method for generating large amounts of hPSCs for cell therapies.

Abstract
The liver is a fascinating organ and performs a wide range of functions necessary for life. Because the hepatocyte is the major functional cell type found in the liver, it is important that we better understand its role in health and disease. Functional hepatocytes have been derived from many sources, including human stem cell populations. These models offer new opportunities to further our understanding of human liver biology from diverse genotypes and, in the future, to facilitate the development of novel medicines or cell-based therapies. This review discusses limitations in current cell-based models and the advantages offered by pluripotent stem cell-derived hepatocytes.

Abstract
Recent advances in human embryonic and induced pluripotent stem cell-based therapies in animal models of hepatic failure have led to an increased appreciation of the need to translate the proof-of-principle concepts into more practical and feasible protocols for scale up and manufacturing of functional hepatocytes. In this study, we describe a scalable stirred-suspension bioreactor culture of functional hepatocyte-like cells (HLCs) from the human pluripotent stem cells (hPSCs). To promote the initial differentiation of hPSCs in a carrier-free suspension stirred bioreactor into definitive endoderm, we used rapamycin for "priming" phase and activin A for induction. The cells were further differentiated into HLCs in the same system. HLCs were characterized and then purified based on their physiological function, the uptake of DiI-acetylated low-density lipoprotein (LDL) by flow cytometry without genetic manipulation or antibody labeling. The sorted cells were transplanted into the spleens of mice with acute liver injury from carbon tetrachloride. The differentiated HLCs had multiple features of primary hepatocytes, for example, the expression patterns of liver-specific marker genes, albumin secretion, urea production, collagen synthesis, indocyanin green and LDL uptake, glycogen storage, and inducible cytochrome P450 activity. They increased the survival rate, engrafted successfully into the liver, and continued to present hepatic function (i.e., albumin secretion after implantation). This amenable scaling up and outlined enrichment strategy provides a new platform for generating functional HLCs. This integrated approach may facilitate biomedical applications of the hPSC-derived hepatocytes.

Abstract
BACKGROUND Human embryonic stem cells (hESCs) have the potential to provide an unlimited source of cardiomyocytes, which are invaluable resources for drug or toxicology screening, medical research, and cell therapy. Currently a number of obstacles exist such as the insufficient efficiency of differentiation protocols, which should be overcome before hESC-derived cardiomyocytes can be used for clinical applications. Although the differentiation efficiency can be improved by the genetic manipulation of hESCs to over-express cardiac-specific transcription factors, these differentiated cells are not safe enough to be applied in cell therapy. Protein transduction has been demonstrated as an alternative approach for increasing the efficiency of hESCs differentiation toward cardiomyocytes. METHODS We present an efficient protocol for the differentiation of hESCs in suspension by direct introduction of a LIM homeodomain transcription factor, Islet1 (ISL1) recombinant protein into the cells. RESULTS We found that the highest beating clusters were derived by continuous treatment of hESCs with 40 µg/ml recombinant ISL1 protein during days 1-8 after the initiation of differentiation. The treatment resulted in up to a 3-fold increase in the number of beating areas. In addition, the number of cells that expressed cardiac specific markers (cTnT, CONNEXIN 43, ACTININ, and GATA4) doubled. This protocol was also reproducible for another hESC line. CONCLUSIONS This study has presented a new, efficient, and reproducible procedure for cardiomyocytes differentiation. Our results will pave the way for scaled up and controlled differentiation of hESCs to be used for biomedical applications in a bioreactor culture system.

The Iranian government and scientific community have jointly started programs to support the creation of new scientific opportunities and technology platforms for research in the domain of stem cell and tissue engineering. In addition, clinical translation of basic researches in the fields of stem cell and regenerative medicine has been amongst the top priorities. Interestingly, the public sector, media, and authorities are also actively monitoring these attainments. In spite of this nationwide interest, however, there is currently a dearth of analytical information on these accomplishments. To address this issue, here we introduce the key decisions made by the country's policy makers and also review some of the Iranian researchers' publications in this field.

Abstract
Human pluripotent stem cells (hPSCs), including human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs), are capable of differentiating into any cell type in the human body and thus can be used in studies of early human development, as cell models for different diseases and eventually also in regenerative medicine applications. Since the first derivation of hESCs in 1998, a variety of culture conditions have been described for the undifferentiated growth of hPSCs. In this study, we cultured both hESCs and hiPSCs in three different culture conditions: on mouse embryonic fibroblast (MEF) and SNL feeder cell layers together with conventional stem cell culture medium containing knockout serum replacement and basic fibroblast growth factor (bFGF), as well as on a Matrigel matrix in mTeSR1 medium. hPSC lines were subjected to cardiac differentiation in mouse visceral endodermal-like (END-2) co-cultures and the cardiac differentiation efficiency was determined by counting both the beating areas and Troponin T positive cells, as well as studying the expression of OCT-3/4, mesodermal Brachyury T and NKX2.5 and endodermal SOX-17 at various time points during END-2 differentiation by q-RT-PCR analysis. The most efficient cardiac differentiation was observed with hPSCs cultured on MEF or SNL feeder cell layers in stem cell culture medium and the least efficient cardiac differentiation was observed on a Matrigel matrix in mTeSR1 medium. Further, hPSCs cultured on a Matrigel matrix in mTeSR1 medium were found to be more committed to neural lineage than hPSCs cultured on MEF or SNL feeder cell layers. In conclusion, culture conditions have a major impact on the propensity of the hPSCs to differentiate into a cardiac lineage.

Abstract
Analysis of gene expression to define molecular mechanisms and pathways involved in human embryonic stem cells (hESCs) proliferation and differentiations has allowed for further deciphering of the self-renewal and pluripotency characteristics of hESC. Proteins associated with hESCs were discovered through isobaric tags for relative and absolute quantification (iTRAQ). Undifferentiated hESCs and hESCs in different stages of spontaneous differentiation by embryoid body (EB) formation were analyzed. Using the iTRAQ approach, we identified 156 differentially expressed proteins involved in cell proliferation, apoptosis, transcription, translation, mRNA processing, and protein synthesis. Proteins involved in nucleic acid binding, protein synthesis, and integrin signaling were downregulated during differentiation, whereas cytoskeleton proteins were upregulated. The present findings added insight to our understanding of the mechanisms involved in hESC proliferation and differentiation.

Abstract
Current protocols for the scalable suspension culture of human pluripotent stem cells (hPSCs) are limited by multiple biological and technical challenges that need to be addressed before their use in clinical trials. To overcome these challenges, we have developed a novel bioprocess platform for large-scale expansion of human embryonic and induced pluripotent stem cell lines as three-dimensional size-controlled aggregates. This novel bioprocess utilizes the stepwise optimization of both static and dynamic suspension culture conditions. After screening eight xeno-free media in static suspension culture and optimizing single-cell passaging in dynamic conditions, the scale-up from a static to a dynamic suspension culture in the stirred bioreactor resulted in a two- to threefold improvement in expansion rates, as measured by cell counts and metabolic activity. We successfully produced size-specific aggregates through optimization of bioreactor hydrodynamic conditions by using combinations of different agitation rates and shear protectant concentrations. The expansion rates were further improved by controlling oxygen concentration at normoxic conditions, and reached a maximum eightfold increase for both types of hPSCs. Subsequently, we demonstrated a simple and rapid scale-up strategy that produced clinically relevant numbers of hPSCs (∼2×10(9) cells) over a 1-month period by the direct transfer of "suspension-adapted frozen cells" to a stirred suspension bioreactor. We omitted the required preadaptation passages in the static suspension culture. The cells underwent proliferation over multiple passages in the demonstrated xeno-free dynamic suspension culture while maintaining their self-renewal capabilities, as determined by marker expressions and in vitro spontaneous differentiation. In conclusion, suspension culture protocols of hPSCs could be used to mass produce homogenous and pluripotent undifferentiated cells by identification and optimization of key bioprocess parameters that are complemented by a simple and rapid scale-up platform.

Abstract
Human embryonic and induced pluripotent stem cells (hESCs and hiPSCs) offer a platform technology with the potential for developmental biology and cell-based therapy. Therefore, robust and cost-effective ways for mass production of them is necessary. Here, we have presented a protocol to grow pluripotent hESCs and hiPSCs in suspension by using a simple, inexpensive, microcarrier-free method. Under this condition, the cells maintained stability during freeze/thaw cycles without the loss of pluripotency markers for extended periods (>1 year). The cells maintained a stable karyotype and showed very similar expression profiles when compared to the adherent culture. The combination of this system with a bioreactor culture system will allow scale up culture of hESCs and hiPSCs needed for clinical and translational applications.

Abstract
While defining the environment for human embryonic stem cell (hESC) culture on 2-dimensional (2D) surfaces has made rapid progress, the industrial-scale implementation of this technology will benefit from translating this knowledge into a 3-dimensional (3D) system, thus enabling better control, automation, and volumetric scale-up in bioreactors. The current study describes a system with defined conditions that are capable of supporting the long-term 2D culture of hESCs and the transposing of these conditions to 3D microcarrier (MC) cultures. Vitronectin (VN) and laminin (LN) were chosen as matrices for the long-term propagation of hESCs in a defined culture medium (STEMPRO(®)) for conventional 2D culture. Adsorption of these proteins onto 2D tissue culture polystyrene (TCPS) indicated that surface density saturation of 510 and 850 ng/cm(2) for VN and LN, respectively, was attained above 20 μg/mL deposition solution concentration. Adsorption of these proteins onto spherical (97±10 μm), polystyrene MC followed a similar trend and coating surface densities of 450 and 650 ng/cm(2) for VN and LN, respectively, were used to support hESC propagation. The long-term expansion of hESCs was equally successful on TCPS and MC, with consistently high expression (>90%) of pluripotent markers (OCT-4, MAB-84, and TRA-1-60) over 20 passages and maintenance of karyotypic normality. The average fold increase in cell numbers on VN-coated MC per serial passage was 8.5±1.0, which was similar to LN-coated MC (8.5±0.9). Embryoid body differentiation assays and teratoma formation confirmed that hESCs retained the ability to differentiate into lineages of all 3 germ layers, thus demonstrating the first translation to a fully defined MC-based environment for the expansion of hESCs.

Abstract
Induced pluripotent stem cells (iPSCs) can provide an important source of cells for the next-generation of cell therapies in regenerative medicine, in part due to their similarity to embryonic stem cells (ESCs). Patient-specific iPSCs represent an opportunity for autologous cell therapies that are not restricted by immunological, ethical and technical obstacles. One of the technical hurdles that must be overcome before iPSCs can be clinically implemented is the scalable, reproducible production of iPSCs and their differentiated progeny. All of the iPSC lines established thus far have been generated and expanded with static tissue culture protocols, which are time-consuming and suffer from batch-to-batch variability. Alternatively, stirred suspension bioreactors propose several benefits and their homogeneous culture environment facilitates the large-scale expansion required for clinical studies at less cost. We have previously developed protocols for expanding murine and human ESCs as undifferentiated aggregates in stirred suspension bioreactors. The resulting cells were karyotypically normal, expressed pluripotency markers and could be differentiated into all three germ lineages, both in vitro and in vivo. In this study, we demonstrate that stirred suspension bioreactors yield 58-fold expansion of undifferentiated pluripotent iPSCs over 4 days. In vitro differentiation into cartilage, bone and cardiomyocytes lineages, in addition to in vivo teratoma formation, further confirmed the existence of fully functional and undifferentiated pluripotent iPSC aggregates following long-term passaging. Stirred suspension bioreactor culture represents an efficient process for the large-scale expansion and maintenance of iPSCs, which is an important first step in their clinical application.

Abstract
We have generated a human feeder cell line from early second trimester Placental Stromal Fibroblasts (ihPSF) stably over-expressing the polycomb protein BMI-1. These feeder cells retain the ability to maintain human Embryonic Stem cells (hESc) over long-term culture whereas hTERT or BMI-1/hTERT immortalised feeder cell lines do not. ihPSFs were able to support the derivation of a new hESc line in near xenofree (free of non-human animal components) conditions and support continued culture of newly derived hESc and human induced Pluripotent Stem (hiPS) cell lines in complete xenofree conditions necessary for clinical use.
