BACKGROUND The standard treatment for decompensated liver cirrhosis is liver transplantation. However, it has several limitations. Recent animal studies suggest that bone marrow stem cell transplantation can lead to regression of liver fibrosis. The objective of this study was to determine the safety and feasibility of autologous bone marrow-mesenchymal(More)
Human embryonic stem cells (hESCs) have enormous potential as a source of cells for cell replacement therapies and as a model for early human development. In this study we examined the differentiating potential of hESCs into hepatocytes in two- and three-dimensional (2D and 3D) culture systems. Embryoid bodies (EBs) were inserted into a collagen scaffold 3D(More)
The International Stem Cell Initiative analyzed 125 human embryonic stem (ES) cell lines and 11 induced pluripotent stem (iPS) cell lines, from 38 laboratories worldwide, for genetic changes occurring during culture. Most lines were analyzed at an early and late passage. Single-nucleotide polymorphism (SNP) analysis revealed that they included(More)
There are limited data available on the effect of a physicochemical microenvironment on mesenchymal stem cell (MSC) differentiation and repopulation of the liver. Therefore, in this study nanofibers have been used to better differentiate and maintain the function and engraftment of differentiating MSCs both in vitro and in vivo. Mouse MSCs were(More)
Human embryonic stem cells (hESC) represent a population of undifferentiated pluripotent cells with both self-renewal and multilineage differentiation characteristics. Proteomics provides a powerful approach for studying the characteristics of hESC and discovering molecular markers. We have analyzed proteome profiles of three hESC lines using 2-DE and MALDI(More)
Extracellular matrix (ECM) components significantly influence the growth characteristics of cardiomyocytes, development of spontaneous contractile activity and morphologic differentiation. The present study involves characterization of ES cell-derived cardiomyocytes cultured on different ECMs. We hypothesized that cardiogel, which is a naturally occurring(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)
Embryonic stem cells (ESCs) are considered one promising new approach to generate a transplantable cell source for the treatment of liver diseases. Because traditional methods, such as the initial formation of embryoid body in the presence of serum result in all three germ layer derivatives, strategies have been utilized that favor cell-specific(More)
Alzheimer's disease (AD) is a neurodegenerative disorder that is characterized by progressive and irreversible decline of memory. Neuropathological features include the progressive degeneration of cholinergic neurons in the forebrain cholinergic projection system especially nucleus basalis of Meynert (nbM). New cell therapeutic approaches for the(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)
