embryonic stem cell (ESC)
1. A cell taken from an early embryo and intended for therapeutic application of its totipotential property.
2. A cell derived from an embryo resulting from a donated egg whose nucleus has been removed and replaces by a cell from a prospective patient. During pregnancy some ESCs pass across the placental barrier and enter the mothers bloodstream. There are suggestions that these stem cells may repair damaged maternal organs, including the brain. Cells can be derived from umbilical cord blood that appear to have most of the properties of ESCs.
