objective: in this investigation murine embryonic stem (es) cells were differentiated into endothelial cells. materials and methods: murine es cells (cce cell line) exposed to alpha-mem medium containing 10% fbs for 4 days. then obtained flk-1 (flk-1: vascular endothelial growth factor receptor 2) positive cells were cultuted in endothelial growth medium-2 (egm-2) until the last day of experime...

Embryonic stem (ES) cells hold great potential as a renewable cell source for regenerative medicine and cell-based therapy. Despite the potential of ES cells, conventional stem cell culture methods do not enable the control of the microenvironment. A number of microscale engineering approaches have been recently developed to control the extracellular microenvironment and to direct embryonic ste...

Stem cells are unique cell populations with the ability to undergo both self-renewal and differentiation. A wide variety of adult mammalian tissues harbors stem cells, yet "adult" stem cells may be capable of developing into only a limited number of cell types. In contrast, embryonic stem (ES) cells, derived from blastocyst-stage early mammalian embryos, have the ability to form any fully diffe...

BACKGROUND Human induced pluripotent stem (iPS) cells are currently used as powerful resources in regenerative medicine. During very early developmental stages, DNA methylation decreases to an overall low level at the blastocyst stage, from which embryonic stem cells are derived. Therefore, pluripotent stem cells, such as ES and iPS cells, are considered to have hypo-methylated status compared ...

The recent isolation of human embryonic stem (ES) cells is evoking great hopes for their future utilization in cell-replacement therapies and human development research. The hallmarks of ES cells, pluripotency and self-renewal capacity, suggest an infinite source for tissues of virtually all desired types. Specifically, human ES cells may potentially be the basis for effective treatments of a w...

Inductive signals and transcription factors involved in motor neuron generation have been identified, raising the question of whether these developmental insights can be used to direct stem cells to a motor neuron fate. We show that developmentally relevant signaling factors can induce mouse embryonic stem (ES) cells to differentiate into spinal progenitor cells, and subsequently into motor neu...

This article is to try describing the renal stem cells in animal and to explore the methods to either repair or regenerate a damaged kidney with stem cells. For this purpose, the 3 sections are concerned: (1) Isolation of stem cells from animal embryo and/or other resources (such as adipose and renal tissue). (2) Embryonic stem (ES) cells differentiate into renal stem cells and/or renal progeni...

The advent of reprogramming and its impact on stem cell biology has renewed interest in lineage restriction in mammalian embryos, the source of embryonic (ES), epiblast (EpiSC), trophoblast (TS), and extraembryonic endoderm (XEN) stem cell lineages. Isolation of specific cell types during stem cell differentiation and reprogramming, and also directly from embryos, is a major technical challenge...

Pluripotent stem cells have the potential to differentiate into 200 odd cell types present in adult body. Pluripotent stem cells available for regenerative medicine include embryonic stem (ES) cells, induced pluripotent stem (iPS) cells and very small ES-like stem (VSELs) cells. Nuclear OCT-4 is one of the crucial factors that dictate pluripotent state. Compared to ES/iPS cells grown in Petri d...
