  • Concise Review: Genetic and Epigenetic Regulation of Cardiac Differentiation from Human Pluripotent Stem Cells

    © AlphaMed Press 2019 Human pluripotent stem cells (hPSCs), including both embryonic stem cells and induced pluripotent stem cells, are the ideal cell sources for disease modeling, drug discovery, and regenerative medicine. In particular, regenerative therapy with hPSC-derived cardiomyocytes (CMs) is an unmet medical need for the treatment of severe heart failure. Cardiac differentiation protocols from hPSCs are made on the basis of cardiac development in vivo. However, current protocols have yet to yield 100% pure CMs, and their maturity is low. Cardiac development is regulated by the cardiac gene network, including transcription factors (TFs). According to our current understanding of cardiac development, cardiac TFs are sequentially expressed during cardiac commitment in hPSCs. Expression levels of each gene are strictly regulated by epigenetic modifications. DNA methylation, histone modification, and noncoding RNAs significantly influence cardiac differentiation. These complex circuits of genetic and epigenetic factors dynamically affect protein expression and metabolic changes in cardiac differentiation and maturation. Here, we review cardiac differentiation protocols and their molecular machinery, closing with a discussion of the future challenges for producing hPSC-derived CMs. Stem Cells 2019;37:992–1002.

    © 2019 Elsevier Inc. Immunogenicity of immature pluripotent stem cells is a topic of intense debate. Immunogenic antigens, which are specific in pluripotent states, have not been described previously. In this study, we identified glypican-3 (GPC3), a known carcinoembryonic antigen, as a pluripotent state-specific immunogenic antigen. Additionally, we validated the applicability of human leukocyte antigen (HLA)-class I-restricted GPC3-reactive cytotoxic T lymphocytes (CTLs) in the removal of undifferentiated pluripotent stem cells (PSCs) from human induced pluripotent stem cell (hiPSC)-derivatives. HiPSCs uniquely express GPC3 in pluripotent states and were rejected by GPC3-reactive CTLs, which were sensitized with HLA-class I-restricted GPC3 peptides. Furthermore, GPC3-reactive CTLs selectively removed undifferentiated PSCs from hiPSC-derivatives in vitro and inhibited tumor formation in vivo. Our results demonstrate that GPC3 works as a pluripotent state-specific immunogenic antigen in hiPSCs and is applicable to regenerative medicine as a method of removing undifferentiated PSCs, which are the main cause of tumor formation.

  • Development of a transplant injection device for optimal distribution and retention of human induced pluripotent stem cell‒derived cardiomyocytes

    © 2018 Elsevier Ltd BACKGROUND: Induced pluripotent stem cell (iPSC)‒based regenerative therapy is a promising strategy for cardiovascular disease treatment; however, the method is limited by the myocardial retention of grafted iPSCs. Thus, an injection protocol that efficiently introduces and retains human iPSC-derived cardiomyocytes (hiPSC-CMs) within the myocardium is urgently needed. The objective of the present study was to develop a method to improve the retention of hiPSCs in the myocardium for cardiac therapy. METHODS: We efficiently produced hiPSC-CM spheroids in 3-dimensional (3D) culture using microwell plates, and developed an injection device for optimal 3D distribution of the spheroids in the myocardial layer. Device biocompatibility was assessed with purified hiPSC-CM spheroids. Device effectiveness was evaluated in 10- to 15-month-old farm pigs (n = 15) and 5- to 24-month-old micro-minipigs (n = 20). The pigs were euthanized after injection, and tissues were harvested for retention and histologic analysis. RESULTS: We demonstrated an injection device for direct intramyocardial transplantation of hiPSC-CM spheroids from large-scale culture. The device had no detrimental effects on cell viability, spheroid shape, or size. Direct epicardial injection of spheroids mixed with gelatin hydrogel into beating porcine hearts using this device resulted in better distribution and retention of transplanted spheroids in a layer within the myocardium than did conventional needle injection procedures. CONCLUSIONS: The combination of the newly developed transplant device and spheroid formation promotes the retention of transplanted CMs. These findings support the clinical application of hiPSC-CM spheroid‒based cardiac regenerative therapy in patients with heart failure.

    © 2018 The Author(s) Deep learning technology is rapidly advancing and is now used to solve complex problems. Here, we used deep learning in convolutional neural networks to establish an automated method to identify endothelial cells derived from induced pluripotent stem cells (iPSCs), without the need for immunostaining or lineage tracing. Networks were trained to predict whether phase-contrast images contain endothelial cells based on morphology only. Predictions were validated by comparison to immunofluorescence staining for CD31, a marker of endothelial cells. Method parameters were then automatically and iteratively optimized to increase prediction accuracy. We found that prediction accuracy was correlated with network depth and pixel size of images to be analyzed. Finally, K-fold cross-validation confirmed that optimized convolutional neural networks can identify endothelial cells with high performance, based only on morphology. Kusumoto et al. developed an automated system to identify endothelial cells derived from induced pluripotent stem cells, based only on morphology. Performance, as assessed by F1 score and accuracy, was correlated with network depth and pixel size of training images. K-fold validation confirmed that endothelial cells are identified automatically with high accuracy using only generalized morphological features.
