Optimization and development of better defined culture methods for human embryonic and induced pluripotent stem cells (hESCs and hiPSCs) will provide an invaluable contribution to the field of regenerative medicine. However, one problem is the vulnerability of hESCs and hiPSCs to apoptosis that causes a low plating efficiency upon passaging. Herein, we have(More)
Schwann cells (SCs) can be used to repair both the peripheral and central nervous systems. Therefore, establishment of a procedure to obtain activated, highly proliferative SCs, in an appropriate time for clinical applications, is a prerequisite. Purification is complicated by contamination with fibroblasts which often become the predominant cell type in an(More)
The recent generation of induced pluripotent stem cells (iPSCs) from somatic cells provides an invaluable resource for drug or toxicology screening, medical research, and patient-specific cell therapy. However, there are currently a number of obstacles including virus integration and the genetic alteration of iPSCs that will need to be overcome before these(More)
Embryonic stem (ES) cells are pluripotent cells derived from the inner cell mass of blastocysts. These cells are appropriate for creation of animal models of human genetic diseases, the study of gene function in vivo and differentiation into specific types as potential therapeutic agents for several human diseases. We describe here, the production of new ES(More)
The CD133(+) bone marrow cell (BMC) population includes primitive multipotent stem cells which induce neoangiogenesis. Studies suggested transplantation of these cells to infarcted myocardium can have a favorable impact on tissue perfusion and contractile performance. We assessed the feasibility, safety and functional outcomes of autologus CD133(+) BMC(More)
Human pluripotent embryonic stem cells (hESC) have great promise for research into human developmental biology and the development of cell therapies for the treatment of diseases. To meet the increased demand for characterized hESC lines, we present the derivation and characterization of five hESC lines on mouse embryonic fibroblast cells. Our stem cell(More)
Human-induced pluripotent stem cell-derived neural progenitors (hiPSC-NPs) have the ability to self-renew and differentiate into glial and neuronal lineages, which makes them an invaluable source in cell replacement therapy for neurological diseases. Therefore, their enhanced proliferation and neuronal differentiation are pivotal features that can be used(More)
Fibronectin type III domain-containing 5 protein (Fndc5) or peroxisomal protein, is a type I membrane protein that has 209 amino acid residues. Previous studies by our group have shown an increase in its expression after retinoic acid treatment of mouse embryonic stem cells (mESCs) during the process of neural differentiation, leading us to conclude that it(More)
Global gene expression analysis of human embryonic stem cells (hESCs) that differentiate into neural cells would help to further define the molecular mechanisms involved in neurogenesis in humans. We performed a comprehensive transcripteome analysis of hESC differentiation at three different stages: early neural differentiation, neural ectoderm, and(More)
Human induced pluripotent stem cells (hiPSCs) have led to an important revolution in stem cell research and regenerative medicine. To create patient-specific neural progenitors (NPs), we have established a homogenous, expandable, and self-renewable population of multipotent NPs from hiPSCs, using an adherent system and defined medium supplemented with a(More)
