Introduction: Patient-specific human induced pluripotent stem cells (hiPSC)-derived cardiomyocytes (CMs) are increasingly used for in vitro disease modeling and drug screening, as well in vivo regenerative therapies. The cardiac differentiation efficacy of hiPSCs, together with the maturation level of generated CMs, are critical factors in achieving the required numbers of functional patient-specific cardiac muscle cells for clinical applications. Although extensive studies have improved the efficacy of differentiation and maturation processes, the role of cell sex in these processes has not been fully investigated. Hypothesis: Cell sex affects i) the cardiogenic differentiation efficacy of hiPSCs; and ii) maturation processes of hiPSC-CMs. Methods and Results: We have successfully and reproducibly fabricated patterned substrates recapitulating the 3D shape of mature CMs, using photolithography approaches, and demonstrated that the substrate could i) accelerate the differentiation of hiPSCs to CMs, and ii) facilitate maturation and functionality of immature hiPSC-CMs. Male and female hiPSCs, derived from human amniotic mesenchymal stem cells of male and female fetuses, were cultured onto flat (control) vs. patterned substrates. A total of 400 differentiation assays were conducted, 200 per each cell sex, on the flat ( n = 100) and patterned ( n = 100) substrates. A chemically defined approach was used to differentiate the cells toward CMs. On the flat (conventional) substrates, 59% of batches of male and 87% of batches of female hiPSCs differentiated into beating CMs (> 80%). On the patterned substrates, these numbers changed to 83% and 94% of successful differentiations for male and female hiPSCs, respectively. These results indicate the significant effect of substrate-mediated topographical cues on the cardiac differentiation yield of stem cells and the batch-to-batch variation. On both substrate types, female cells demonstrated significantly higher success rates of cardiac differentiation compared to the male cells. In addition, the CMs produced on the patterned substrates demonstrated higher purity than those created on the flat substrates both for male and female cells. Quantitative polymerase chain reaction (qPCR) was used to probe the male and female cell differences in expression of genes related to cardiac maturity, contractility, and Ca 2+ transport (TNNT2, MYH6, MYH7, and CACNA1c) and the outcomes revealed substantially greater expression levels of the maturation genes in differentiated female CMs cultured on the patterned substrates compared to the male cells. Conclusions: These results indicate that male and female hiPSCs and hiPSC-CMs respond differently to the identical substrates in terms of their differentiation and maturation efficacies.

Stem cells in large animals are an excellent model for cell therapy research and fine resources for producing transgenic animals. However, there are only few reports of stem cells in large animals because of technical differences between species. In this report, we successfully generate bovine induced pluripotent stem cells (iPSC) using 4 human reprogramming factors (Oct4, Sox2, Klf4, and c-myc) under control of PiggyBac transposition vector. Fibroblasts derived from bovine fetuses were transfected using FugeneHD agent. After 21 days, colony-shaped structures on the culture plates were mechanically detached and then seeded on a mouse embryonic fibroblast (MEF) feeder layer pretreated with mitomycin C. The culture medium was DMEM/F12 supplemented with 20% serum replacement, 5 ng mL–1 basic fibroblast growth factor (bFGF), 0.1 mM β-mercaptoethanol, 1% NEAA, and 1% penicillin-streptomycin antibiotics. The iPSC colonies showed alkaline phosphatase activity and expressed several pluripotency markers (Oct4, Sox2, SSEA1, and SSEA4). To confirm differentiation potential, the iPSC were cultured as embryoid bodies and then plated again. βIII-tubulin (ectoderm) and GFAP or α-SMA (mesoderm) were well expressed on the attached cells. The results revealed that the bovine fibroblasts were well inducted to iPSC that had potential of multilineage differentiation. We hope this technology contributes to improving transgenic cattle production.

Background.Human induced pluripotent stem cells (iPSCs) are an attractive source of cardiomyocytes for cardiac repair and regeneration. In this study, we aim to determine whether acute electrical stimulation of human iPSCs can promote their differentiation to cardiomyocytes.Methods. Human iPSCs were differentiated to cardiac cells by forming embryoid bodies (EBs) for 5 days. EBs were then subjected to brief electrical stimulation and plated down for 14 days.Results. In iPS(Foreskin)-2 cell line, brief electrical stimulation at 65 mV/mm or 200 mV/mm for 5 min significantly increased the percentage of beating EBs present by day 14 after plating. Acute electrical stimulation also significantly increased the cardiac gene expression ofACTC1,TNNT2,MYH7, andMYL7. However, the cardiogenic effect of electrical stimulation was not reproducible in another iPS cell line, CERA007c6. Beating EBs from control and electrically stimulated groups expressed various cardiac-specific transcription factors and contractile muscle markers. Beating EBs were also shown to cycle calcium and were responsive to the chronotropic agents, isoproterenol and carbamylcholine, in a concentration-dependent manner.Conclusions. Our results demonstrate that brief electrical stimulation can promote cardiac differentiation of human iPS cells. The cardiogenic effect of brief electrical stimulation is dependent on the cell line used.
