- Comment 1. Embryonic stem cells are pluripotent or totipotent, i.e., during normal development or upon transfer into an appropriate host or environment, they have the potential to differentiate into every adult cell type or to produce a whole animal from a single cell. The term usually refers to stem cells from the mammalian embryo. The mammalian zygote and cells produced by early zygotic divisions up to around the blastocyst stage are examples of ESCs. ESCs derived from cultured mouse blastocyst cells differentiate into teratocarcinomas when injected into immunodeficient mice, produce pure lines of pluripotent cells under appropriate experimental conditions, and when injected into a host blastocyst, form nearly all the tissues of the chimeric adult animal. 2. Most embryonic stem cells are derived from embryos that develop from eggs that have been fertilised in vitro — in an in vitro fertilisation clinic — and then donated for research purposes with informed consent of the donors. They are not derived from eggs fertilized in a woman's body.References:1.'stem cells' in 'A Dictionary of Genetics'. Robert C. King, William D. Stansfield and Pamela K. Mulligan.
