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.

Best Practice & Research Clinical Obstetrics & Gynaecology, 2016
The establishment of permanent human embryonic stem cell lines (hESCs) was first reported in 1998. Due to their pluripotent nature and ability to differentiate to all cell types in the body, they have been considered as a cell source for regenerative medicine. Since then, intensive studies have been carried out regarding factors regulating pluripotency

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

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-

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).

Stem cells can be isolated from a variety of sources and they are typically classified based on their tissue of origin. Embryonic stem cells are, as the name indicates, derived from the inner cell mass of pre-implantation stage blastocysts at day 5–7 post fertilisation.

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.

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.

Stem cells, which have a great capacity for self-renewal and can differentiate into at least one committed cell type, exist in embryonic and adult organisms of many phyla. Although stem cells of various types from mice and other lower organisms have been studied for many years, it was not until the derivation of stem cell lines from human embryos in ...

Zebrafish Embryonic Stem Cells
2006Methods are presented for the derivation of zebrafish embryonic stem (ES) cell cultures that are initiated from blastula and gastrula stage embryos. To maintain pluripotency, the ES cells are cocultured with rainbow trout spleen cells from the RTS34st cell line.
