Human induced pluripotent stem cells (hiPSCs) can be expanded at limitless scale in vitro and give rise to various organotypic cells, cardiomyocytes (CMs) among them. Advanced protocols shape the differentiation process of pluripotent stem cells by controlled growth factor application. Modulating the Wnt signaling pathway is effective to direct hiPSCs to CMs (hiPSC-CMs) and native growth factors were replaced by small chemical compounds. Here, we describe a refined protocol for scalable generation of hiPSC-CMs that manipulates porcupine and tankyrase sub-pathways of Wnt signaling for tight inhibition of non-canonical Wnt signaling. The approach results in a differentiation efficiency toward hiPSC-CMs of 87 ± 0.9% in stirred bioreactor cultures and yields about 70 million hiPSC-CMs per 100 mL serum free cardiac differentiation medium. The differentiation protocol is easily adapted from 3D to 2D culture and vice versa and has been demonstrated to work with different hiPSC lines.

Myocardial hypertrophy is present in many heart diseases, representing a strong predictor of adverse cardiovascular outcomes. Regarding therapeutic intervention, mesenchymal stem cells (MSCs) have been suggested to significantly reduce cardiac hypertrophy and progression to heart failure. Preconditioning of MSCs was previously demonstrated to highly improve their paracrine activity resulting in modulation of immune responses and the progression of diseases. Here, we studied the effects of bone marrow-derived preconditioned MSCs on hypertrophied induced pluripotent stem cell-derived cardiomyocytes (iPS-CM) and also sought to identify MSC-derived antihypertrophic molecules. Phenylephrine (PE) was used to induce hypertrophy in murine iPS-CM, and markers of hypertrophy were identified by microarray analysis. Murine MSCs were treated with IFN-γ and IL-1β to enhance their paracrine activity, and transcriptional profiling was performed by microarray analysis. Hypertrophied iPS-CM were subsequently cocultured with preconditioned MSCs or MSC-conditioned medium (CM), respectively. Effects on hypertrophied iPS-CM were studied by cell area quantification, real-time PCR, and western blot. In some experiments, cells were incubated with fractions of MSC-CM obtained by ultrafiltration or by MSC-CM supplemented with inhibitory antibodies. Intracellular and extracellular levels of vascular endothelial growth factor (VEGF) were evaluated by western blot and ELISA. PE-induced hypertrophy in iPS-CM was associated with an upregulation of neuron-derived orphan receptor (Nor1) expression, activation of Akt, and inhibition of both strongly prevented hypertrophy induction in iPS-CM. VEGF secreted by preconditioned MSCs provoked hypertrophy regression in iPS-CM, and a negative correlation between Nor1 expression and hypertrophic growth could be evidenced. Our results demonstrate that Nor1 expression strongly supports hypertrophy in iPS-CM. Moreover, the secretome of preconditioned MSCs triggered regression of hypertrophy in iPS-CM in a VEGF-dependent manner. We suggest that the delivery of the MSC-derived secretome may represent a therapeutic strategy to limit cardiac hypertrophy. However, additional in vivo studies are needed to prove this hypothesis.

Cardiomyocytes, differentiated from induced pluripotent stem cells (iPSCs), have the potential to produce patient- and disease-specific pharmacological and toxicological platforms, in addition to their cardiac cell therapy applications. However, the lack of both a robust and a simple procedure for scalable cell substrate production is one of the major limitations in this area. Mimicking the natural healthy myocardium extracellular matrix (ECM) properties by altering the cell substrate properties, such as stiffness and chemical/biochemical composition, can significantly affect cell substrate interfacial characteristics and potentially influence cellular behavior and differentiation of iPSCs to cardiomyocytes. Here, we propose a systematic and biomimetic approach, based on the preparation of poly(dimethylsiloxane) (PDMS) substrates having the similar stiffness as healthy heart tissue and a well-defined surface chemistry obtained by conventional [(3-aminopropyl)triethoxysilane (APTES) and octadecyltrimethoxysilane (OTS)] and amino acid (histidine and leucine)-conjugated self-assembled monolayers (SAMs). Among a wide range of different concentrations, the 50:1 prepolymer cross-linker ratio of PDMS allowed adaptation of the myocardium stiffness with a Young’s modulus of 23.79 ± 0.61 kPa. Compared with conventional SAM modification, amino acid-conjugated SAMs greatly improved iPSC adhesion, viability, and cardiac marker expression by increasing surface biomimetic properties, whereas all SAMs enhanced cell behavior, with respect to native PDMS. Furthermore, leucine-conjugated SAM modification provided the best environment for cardiac differentiation of iPSCs. This optimized approach can be easily adapted for cardiac differentiation of iPSCs in vitro, rendering a very promising tool for microfluidics, drug screening, and organ-on-chip platforms.

Transposon for fluorescent labelling and puromycin selection of human stem cell derived cardiomyocytes
As a service to our colleagues working in the field of human pluripotent stem cell derived cardiomyocytes the Marga and Walter Boll Laboratory for Cardiac Tissue Engineering releases a transposon free of charge via Addgene.org.
To access and order the plasmid go to https://www.addgene.org/163755/
You will receive a plasmid that contains a transposable element. A piggyBac transposase needs to be co-transfected for active insertion of the transposon in the genome. Selection of transfected human iPS cells is performed by Zeocin. Resistant clones need to be differentiated and screened for lines that show bright expression of the red fluorescent protein mCherry. As the coding sequence of mCherry is linked to the coding sequence of puromycin-N-acetyltransferase, red fluorescent cardiomyocytes exhibit resistance to puromycin and can be selected for experiments that require pure cells. Contact us if you need assistance.

Salicylic diamines selectively eliminate residual undifferentiated cells from pluripotent stem cell-derived cardiomyocyte preparations
Sci Rep. 2021 Jan 27;11(1):2391. doi: 10.1038/s41598-021-81351-z.
Clinical translation of pluripotent stem cell (PSC) derivatives is hindered by the tumorigenic risk from residual undifferentiated cells. Here, we identified salicylic diamines as potent agents exhibiting toxicity to murine and human PSCs but not to cardiomyocytes (CMs) derived from them. Half maximal inhibitory concentrations (IC50) of small molecules SM2 and SM6 were, respectively, 9- and 18-fold higher for human than murine PSCs, while the IC50 of SM8 was comparable for both PSC groups. Treatment of murine embryoid bodies in suspension differentiation cultures with the most effective small molecule SM6 significantly reduced PSC and non-PSC contamination and enriched CM populations that would otherwise be eliminated in genetic selection approaches. All tested salicylic diamines exerted their toxicity by inhibiting the oxygen consumption rate (OCR) in PSCs. No or only minimal and reversible effects on OCR, sarcomeric integrity, DNA stability, apoptosis rate, ROS levels or beating frequency were observed in PSC-CMs, although effects on human PSC-CMs seemed to be more deleterious at higher SM-concentrations. Teratoma formation from SM6-treated murine PSC-CMs was abolished or delayed compared to untreated cells. We conclude that salicylic diamines represent promising compounds for PSC removal and enrichment of CMs without the need for other selection strategies.

A teaching tool about the fickle p value and other statistical principles based on real-life data
A poor understanding of statistical analysis has been proposed as a key reason for lack of replicability of many studies in experimental biomedicine. While several authors have demonstrated the fickleness of calculated p values based on simulations, we have experienced that such simulations are difficult to understand for many biomedical scientists and often do not lead to a sound understanding of the role of variability between random samples in statistical analysis. Therefore, we as trainees and trainers in a course of statistics for biomedical scientists have used real data from a large published study to develop a tool that allows scientists to directly experience the fickleness of p values. A tool based on a commonly used software package was developed that allows using random samples from real data. The tool is described and together with the underlying database is made available. The tool has been tested successfully in multiple other groups of biomedical scientists. It can also let trainees experience the impact of randomness, sample sizes and choice of specific statistical test on measured p values. We propose that live exercises based on real data will be more impactful in the training of biomedical scientists on statistical concepts.
Effects of physicochemical properties of polyacrylamide (PAA) and (polydimethylsiloxane) PDMS on cardiac cell behavior
Karim Daliri , Kurt Pfannkuche, Bora Garipcan
In vitro cell culture is commonly applied in laboratories around the world. Cultured cells are either of primary origin or established cell lines. Such transformed cell lines are increasingly replaced by pluripotent stem cell derived organotypic cells with more physiological properties. The quality of the culture conditions and matrix environment is of considerable importance in this regard. In fact, mechanical cues of the extracellular matrix have substantial effects on the cellular physiology. This is especially true if contractile cells such as cardiomyocytes are cultured. Therefore, elastic biomaterials have been introduced as scaffolds in 2D and 3D culture models for different cell types, cardiac cells among them. In this review, key aspects of cell-matrix interaction are highlighted with focus on cardiomyocytes and chemical properties as well as strengths and potential pitfalls in using two commonly applied polymers for soft matrix engineering, polyacrylamide (PAA) and polydimethylsiloxane (PDMS) are discussed.

"In vitro grown micro-tissues for cardiac cell replacement therapy in vivo"

Background/Aims: Different approaches have been considered to improve heart reconstructive medicine and direct delivery of pluripotent stem cell-derived cardiomyocytes (PSC-CMs) appears to be highly promising in this context. However, low cell persistence post-transplantation remains a bottleneck hindering the approach. Here, we present a novel strategy to overcome the low engraftment of PSC-CMs during the early post-transplantation phase into the myocardium of both healthy and cryoinjured syngeneic mice.
Methods: Adult murine bone marrow mesenchymal stem cells (MSCs) and PSC-CMs were co-cultured on thermo-responsive polymers and later detached through temperature reduction, resulting in the protease-free generation of cell clusters (micro-tissues) composed of both cells types. Micro-tissues were transplanted into healthy and cryo-injured murine hearts. Short term cell retention was quantified by real-time-PCR. Longitudinal cell tracking was performed by bioluminescence imaging for four weeks. Transplanted cells were further detected by immunofluorescence staining of tissue sections.
Results: We demonstrated that in vitro grown micro-tissues consisting of PSC-CMs and MSCs can increase cardiomyocyte retention by >10-fold one day post-transplantation, but could not fully rescue a further cell loss between day 1 and day 2. Neutrophil infiltration into the transplanted area was detected in healthy hearts and could be attributed to the cellular implantation rather than tissue damage exerted by the transplantation cannula. Injected PSC-CMs were tracked and successfully detected for up to four weeks by bioluminescence imaging.
Conclusion: This approach demonstrated that in vitro grown micro-tissues might contribute to the development of cardiac cell replacement therapies.

Pathophysiological conditions, such as myocardial infarction and mechanical overload affect the mammalian heart integrity, leading to a stiffened fibrotic tissue. With respect to the pathophysiology of cardiac fibrosis but also in the limelight of upcoming approaches of cardiac cell therapy it is of interest to decipher the interaction of cardiomyocytes with fibrotic matrix. Therefore, we designed a hydrogel-based model to engineer fibrotic tissue in vitro as an approach to predict the behavior of cardiomyocytes facing increased matrix rigidity. Here, we generated pure induced pluripotent stem cell-derived cardiomyocytes and cultured them on engineered polyacrylamide hydrogels matching the elasticities of healthy as well as fibrotic cardiac tissue. Only in cardiomyocytes cultured on matrices with fibrotic-like elasticity, transcriptional profiling revealed a substantial up-regulation of a whole panel of cardiac fibrosis-associated transcripts, including collagen I and III, decorin, lumican, and periostin. In addition, matrix metalloproteinases and their inhibitors, known to be essential in cardiac remodeling, were found to be elevated as well as insulin-like growth factor 2. Control experiments with primary cardiac fibroblasts were analyzed and did not show comparable behavior. In conclusion, we do not only present a snapshot on the transcriptomic fingerprint alterations in cardiomyocytes under pathological conditions but also provide a new reproducible approach to study the effects of fibrotic environments to various cell types.
