Multipotent Embryonic Isl1+ Progenitor Cells Lead to Cardiac, Smooth Muscle, and Endothelial Cell Diversification

TLDR
These studies document a developmental paradigm for cardiogenesis, where muscle and endothelial lineage diversification arises from a single cell-level decision of a multipotent isl1(+) cardiovascular progenitor cell (MICP).

Differentiation of embryonic stem cells to clinically relevant populations: lessons from embryonic development.

TL;DR: The potential to generate virtually any differentiated cell type from embryonic stem cells (ESCs) offers the possibility to establish new models of mammalian development and to create new sources of cells for regenerative medicine, but it is essential to be able to control ESC differentiation and to direct the development of these cells along specific pathways.

Human cardiovascular progenitor cells develop from a KDR + embryonic-stem-cell-derived population

TL;DR: Analysis of the development of the cardiovascular lineages in human embryonic stem cell differentiation cultures identifies a human cardiovascular progenitor that defines one of the earliest stages of human cardiac development.

miR-145 and miR-143 regulate smooth muscle cell fate and plasticity

TL;DR: It is demonstrated that miR-145 can direct the smooth muscle fate and that mi R-145 and miR -143 function to regulate the quiescent versus proliferative phenotype of smooth muscle cells.
Journal ArticleDOI

Stem-cell therapy for cardiac disease

TL;DR: In conclusion, resident cardiac stem cells have been shown to differentiate into multiple cell types present in the heart, including cardiac muscle cells, indicating that the heart is not terminally differentiated.
Journal ArticleDOI

Patient-specific induced pluripotent stem-cell models for long-QT syndrome.

TL;DR: It was shown that myocytes derived from patients with long-QT syndrome type 1 had an increased susceptibility to catecholamine-induced tachyarrhythmia and that beta-blockade attenuated this phenotype.

Failure of blood-island formation and vasculogenesis in Flk-1-deficient mice.

TL;DR: The generation of mice deficient in Flk-1 by disruption of the gene using homologous recombination in embryonic stem (ES) cells is reported, indicating that FlK-1 is essential for yolk-sac blood-island formation and vasculogenesis in the mouse embryo.

SLAM Family Receptors Distinguish Hematopoietic Stem and Progenitor Cells and Reveal Endothelial Niches for Stem Cells

TL;DR: This work compared the gene expression profiles of highly purified HSCs and non-self-renewing multipotent hematopoietic progenitors and found that both groups occupied multiple niches, including sinusoidal endothelium in diverse tissues.
Journal ArticleDOI

High affinity VEGF binding and developmental expression suggest Flk-1 as a major regulator of vasculogenesis and angiogenesis.

TL;DR: Investigation of flk-1 receptor tyrosine kinase mRNA expression by in situ hybridization analysis revealed specific association with endothelial cells at all stages of mouse development, suggesting a major role of this ligand-receptor signaling system in vasculogenesis and angiogenesis.

Isl1 Identifies a Cardiac Progenitor Population that Proliferates Prior to Differentiation and Contributes a Majority of Cells to the Heart

TL;DR: Two sets of cardiogenic precursors are defined, one of which expresses and requires Isl1 and the other of which does not, which have implications for the development of specific cardiac lineages, left-right asymmetry, cardiac evolution, and isolation of cardiac progenitor cells.
