EMBRYONIC POTENTIAL AND STEM CELLS
Bioethics, 2007ABSTRACTThis paper examines three arguments that use the concept of potential to identify embryos that are morally suitable for embryonic stem cell research (ESCR). According to the first argument, due to Ronald Green, the fact that they are scheduled for disposal makes embryos left over from IVF treatments morally appropriate for research. Paul McHugh

Bovine embryonic stem (bES) cell lines reported to date vary in morphology and marker expression, such as alkaline phosphatase (ALPL), stage-specific embryonic antigen 4 (SSEA4), and octamer-binding transcription factor-4 (OCT4), that normally are associated with the undifferentiated, pluripotent state.

Embryonic stem cells (ESCs) - undifferentiated cells originating from preimplantation stage embryos - have prolonged self-renewal capacity and are pluripotent. Activation of the canonical Wnt pathway is implicated in maintenance of and exit from the pluripotent state. Recent findings demonstrate that the essential mediator of canonical Wnt signaling, β-

The embryonic stem cell test is an animal-free alternative test method for developmental toxicity. Mouse embryonic stem cells are cultured in a hanging drop method to form embryoid bodies. These embryoid bodies, when plated on tissue culture dishes, differentiate to form contracting myocardial cell foci within 10 days.

Pluripotency of embryonic stem cells
Cell and Tissue Research, 2007Embryonic stem (ES) cells derived from pre-implantation embryos have the potential to differentiate into any cell type derived from the three germ layers of ectoderm (epidermal tissues and nerves), mesoderm (muscle, bone, blood), and endoderm (liver, pancreas, gastrointestinal tract, lungs), including fetal and adult cells.

Differentiation of Embryonic Stem Cells
Current Protocols in Neuroscience, 1997AbstractEmbryonic stem (ES) cells are pluripotent cells whose developmental state is equivalent to cells of the inner cell mass in the blastocyst‐stage embryo. This unit presents a method of producing differentiated ES cells in which the cells are first aggregated on a less adhesive surface to form embryoid bodies (EBs).

Embryonic stem (ES) cells are derived from preimplantation stage mouse embryos at the time when they have reached the blastocyst stage. It is at this point that the first steps of differentiation take place during mammalian embryonic development.

Mutation in Embryonic Stem Cells
Science, 2001A single human embryonic stem (es) cell might be modified in the laboratory to provide an unlimited supply of cells for therapy, according to Geron researcher Melissa Carpenter in the News Focus article “Stem cells: new excitement, persistent questions” (G. Vogel, 1 Dec., p.

The Nature of Embryonic Stem Cells
Annual Review of Cell and Developmental Biology, 2014Mouse embryonic stem (ES) cells perpetuate in vitro the broad developmental potential of naïve founder cells in the preimplantation embryo. ES cells self-renew relentlessly in culture but can reenter embryonic development seamlessly, differentiating on schedule to form all elements of the fetus.

Differentiation of Embryonic Stem Cells
Current Protocols in Neuroscience, 2009AbstractMouse embryonic stem (ES) cells are derived from mouse blastocyst and are able to generate all embryonic tissues in vitro. This propensity of ES cells has acquired considerable attention in recent years due to the promising potential for future cell replacement–based therapies.
