Overview

STEMdiff™ Cardiomyocyte Differentiation Kit (Catalog #05010) includes a medium for differentiation of human embryonic stem (ES) and induced pluripotent stem (iPS) cells (human pluripotent stem cells [hPSCs]) into cardiomyocytes (cardiac troponin T-positive [cTnT+]), as well as a medium for maintenance of hPSC-derived cardiomyocytes. This kit can be used to generate cardiomyocytes derived from a clump culture of hPSCs maintained in mTeSR™1 (Catalog #85850), TeSR™-E8™ (Catalog #05990), or mTeSR™ Plus (Catalog #05825). Greater than 80% of these cells will be cTnT+.
An average of 1 x 10^6 cells can be harvested from a single well of a 12-well plate.

STEMdiff™ Cardiomyocyte Maintenance Kit (Catalog #05020) can be used for long-term maintenance of hPSC-derived cardiomyocytes for one month or longer. These cardiomyocytes can be used in various downstream applications and analyses.
Advantages:
• Supports the entire hPSC-derived cardiomyocyte workflow

Figure 1. Cardiomyocyte Differentiation Protocol

Two days before the differentiation protocol, hPSC colonies are harvested and seeded as single cells at 350,000 cells/well in a 12-well format in TeSR™ medium. After one day (Day -1), the medium is replaced with fresh TeSR™ medium. The following day (Day 0), the TeSR™ medium is replaced with Medium A (STEMdiff™ Cardiomyocyte Differentiation Basal Medium containing Supplement A) to begin inducing the cells toward a cardiomyocyte fate. On day 2, a full medium change is performed with fresh Medium B (STEMdiff™ Cardiomyocyte Differentiation Basal Medium containing Supplement B). On days 4 and 6, full medium changes are performed with fresh Medium C (STEMdiff™ Cardiomyocyte Differentiation Basal Medium containing Supplement C). On day 8, medium is switched to STEMdiff™ Cardiomyocyte Maintenance Medium with full medium changes on days 10, 12 and 14, to promote further differentiation into cardiomyocyte cells. Small beating areas of cardiomyocytes can be seen as early as day 8, progressing to a full lawn of beating cardiomyocytes that can be harvested as early as day 15.

Differentiated cells exhibit typical cardiomyocyte morphology as an adherent, tightly packed web-like monolayer of beating cells.

hES and hiPS cells were cultured for 15 days in single wells of 12-well plates using the STEMdiff™ Cardiomyocyte Differentiation Kit. At the end of the culture period, cells were harvested and analyzed by flow cytometry for expression of cardiac troponin T (cTnT).

Microelectrode array (MEA) voltage recordings of cardiomyocytes (day 27) derived from human pluripotent stem cells generated and maintained with the STEMdiff™ Cardiomyocyte Differentiation and Maintenance Kits. The hPSC-derived cardiomyocytes have a characteristic electrical profile and stable beat rate. A large depolarization spike followed by a smaller repolarization deflection is observed.

Characterization of the first induced pluripotent stem cell line generated from a patient with autosomal dominant catecholaminergic polymorphic ventricular tachycardia due to a heterozygous mutation in cardiac calsequestrin-2.

S. Ross et al.

Abstract

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an arrhythmia syndrome characterized by adrenaline induced ventricular tachycardia. The primary genetic aetiologies underlying CPVT are either autosomal dominant or autosomal recessive inheritance, resulting from heterozygous mutations in cardiac ryanodine receptor (RYR2) and homozygous mutations in cardiac calsequestrin-2 (CASQ2), respectively. Recently, a large family with autosomal dominant CPVT due to a heterozygous mutation in CASQ2, p.Lys180Arg, was reported. This resource is the first induced pluripotent stem cell line generated from a patient with autosomal dominant CPVT due to a heterozygous mutation in CASQ2. Induced pluripotent stem cells were generated from the whole blood of a 40-year-old woman with severe CPVT who is heterozygous for the p.Lys180Arg CASQ2 mutation. Induced pluripotent stem cell (iPSC) characterization confirmed expression of pluripotency makers, trilineage differentiation potential, and the absence of exogenous pluripotency vector expression.

Differentiation of lymphoblastoid-derived iPSCs into functional cardiomyocytes, neurons and myoblasts.

H. Poulin et al.

Abstract

Human induced pluripotent stem cells (hiPSCs) are a valuable tool for investigating complex cellular and molecular events that occur in several human diseases. Importantly, the ability to differentiate hiPSCs into any human cell type provides a unique way for investigating disease mechanisms such as complex mental health diseases. The in vitro transformation of human lymphocytes into lymphoblasts (LCLs) using the Epstein-Barr virus (EBV) has been the main method for generating immortalized human cell lines for half a century. However, the derivation of iPSCs from LCLs has emerged as an alternative source from which these cell lines can be generated. We show that iPSCs derived from LCLs using the Sendai virus procedure can be successfully differentiated into cardiomyocytes, neurons, and myotubes that express neuron- and myocyte-specific markers. We further show that these cardiac and neuronal cells are functional and generate action potentials that are required for cell excitability. We conclude that the ability to differentiate LCLs into neurons and myocytes will increase the use of LCLs in the future as a potential source of cells for modelling a number of diseases.

Development of induced pluripotent stem cells from a patient with hypertrophic cardiomyopathy who carries the pathogenic myosin heavy chain 7 mutation p.Arg403Gln.

M. Holliday et al.

Abstract

Hypertrophic cardiomyopathy (HCM) is an inherited cardiomyopathy characterized by left ventricular hypertrophy ≥15 mm in the absence of loading conditions. HCM has a prevalence of up to one in 200, and can result in significant adverse outcomes including heart failure and sudden cardiac death. An induced pluripotent stem cell (iPSC) line was generated from peripheral blood mononuclear cells obtained from the whole blood of a 38-year-old female patient with HCM in which genetic testing identified the well-known pathogenic p.Arg403Gln mutation in myosin heavy chain 7. iPSCs express pluripotency markers, demonstrate trilineage differentiation capacity, and display a normal 46,XX female karyotype. This resource will allow further assessment of the pathophysiological development of HCM.

Linking a cell-division gene and a suicide gene to define and improve cell therapy safety.

Q. Liang et al.

Abstract

Human pluripotent cell lines hold enormous promise for the development of cell-based therapies. Safety, however, is a crucial prerequisite condition for clinical applications. Numerous groups have attempted to eliminate potentially harmful cells through the use of suicide genes1, but none has quantitatively defined the safety level of transplant therapies. Here, using genome-engineering strategies, we demonstrate the protection of a suicide system from inactivation in dividing cells. We created a transcriptional link between the suicide gene herpes simplex virus thymidine kinase (HSV-TK) and a cell-division gene (CDK1); this combination is designated the safe-cell system. Furthermore, we used a mathematical model to quantify the safety level of the cell therapy as a function of the number of cells that is needed for the therapy and the type of genome editing that is performed. Even with the highly conservative estimates described here, we anticipate that our solution will rapidly accelerate the entry of cell-based medicine into the clinic.
