Human ISL1 heart progenitors generate diverse multipotent cardiovascular cell lineages

Human ISL1 heart progenitors generate diverse multipotent cardiovascular cell lineages Recent studies in mice identified multipotent embryonic ISL1+ (Islet 1 expressing) progenitor cells as capable of contributing to all of the major cell types in the heart. Human cardiogenesis is thought to involve more divergent pathways. Now a diverse set of human fetal ISL1+ cardiovascular progenitor populations with multipotent capability has been identified in the right atrium and outflow tract of the developing human heart. Transgenic and gene-targeting techniques applied to human embryonic stem cell lines show that purified populations of these primordial progenitors are capable of self-renewal and expansion prior to differentiation into the three major cell types in the heart — the cardiomyocytes, smooth muscle and endothelia. This has relevance for the production of human models for cardiovascular disease and potentially for human regenerative medicine. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Springer Journals

Abstract

Recent studies in mice identified multipotent embryonic ISL1+ (Islet 1 expressing) progenitor cells as capable of contributing to all of the major cell types in the heart. Human cardiogenesis is thought to involve more divergent pathways. Now a diverse set of human fetal ISL1+ cardiovascular progenitor populations with multipotent capability has been identified in the right atrium and outflow tract of the developing human heart. Transgenic and gene-targeting techniques applied to human embryonic stem cell lines show that purified populations of these primordial progenitors are capable of self-renewal and expansion prior to differentiation into the three major cell types in the heart — the cardiomyocytes, smooth muscle and endothelia. This has relevance for the production of human models for cardiovascular disease and potentially for human regenerative medicine.
