We have demonstrated previously that human embryonic stem (hES) cells possess a
characteristic morphologic, antigenic, and molecular profile that can be used to assess the …

Several laboratories have begun evaluating human ES (hES) cell lines; however, direct
comparisons between different hES cell lines have not been performed. We have …

The derivation of human embryonic stem (hES) cells establishes a new avenue to approach
many issues in human biology and medicine for the first time. To meet the increased …

Human embryonic stem cells (hESCs) are pluripotent cells that have the potential to
differentiate into any tissue in the human body; therefore, they are a valuable resource for …

The number of human embryonic stem cell (hESC) lines available to federally funded US
researchers is currently limited. Thus, determining their basic characteristics and …

Cell replacement therapies have been limited by the availability of sufficient quantities of
cells for transplantation. Human ES (hES) cell lines have recently been generated by …

We compared gene expression profiles of mouse and human ES cells by
immunocytochemistry, RT-PCR, and membrane-based focused cDNA array analysis …

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 …

Human embryonic stem (ES) cells offer substantial opportunities for providing well-defined
differentiated cells for drug discovery, toxicology, and regenerative medicine, but the …

Background Individual differences between human embryonic stem cell (hESC) lines are
poorly understood. Here, we describe the derivation of five hESC lines (called FES 21, 22 …
