Transcriptional profiling by array of human cardiac progenitors and cardiomyocytes generated from embryonic bodies, directed differentiation of hESCs with PDGFa or co-culturing hESCs with END2 cell line.

ABSTRACT: Human cardiomyocytes can be generated from human embryonic stem cells (hESCs) in vitro by a variety of methods, including co-culture with visceral endoderm-like cell lines and growth factor directed differentiation as monolayers or three-dimensional embryonic bodies. To enable the identification, purification and characterisation of human embryonic stem cell derived cardiomyocytes (CMs) and cardiac progenitor cells (CPCs), we introduced sequences encoding GFP into the NKX2-5 locus by homologous recombination. We found that NKX2-5GFP hESCs facilitate quantification of cardiac differentiation, purification of hESC-derived committed cardiac progenitor cells and cardiomyocytes and the standardization of differentiation protocols.

NKX2-5 is expressed in the heart throughout life. We targeted eGFP sequences to the NKX2-5 locus of human embryonic stem cells (hESCs); NKX2-5(eGFP/w) hESCs facilitate quantification of cardiac differentiation, purification of hESC-derived committed cardiac progenitor cells (hESC-CPCs) and cardiomyocytes (hESC-CMs) and the standardization of differentiation protocols. We used NKX2-5 eGFP(+) cells to identify VCAM1 and SIRPA as cell-surface markers expressed in cardiac lineages. ...[more]
