A cell from the blastocyst stage of an embryo that is capable of giving rise to almost all of the cells or tissues in the body.

(ES cell) A totipotent cell from the embryo of a mouse or other organism.

A very early embryonic cell that can either reproduce itself indefinitely or differentiate into a wide variety of specialized cells.

A totipotent cell cultured from an early-stage embryo. Genetic modification of embryonic stem cells produces transgenic animals.

ES cell Totipotent cell cultured from early embryo and can be used to produce chimeric embryos and thus transgenic animals after modification in vitro.

an early embryo cell that has not yet begun to differentiate into various tissues

a pluripotent cell from the inner cell mass of a blastocyst-stage embryo

a cell from an embryo that has the potential to become a wide variety of specialized cell types.

Embryonic stem cells (ESC) are isolated from the inner cell mass (ICM) of the blastocyst — the stage of embryonic development when implantation occurs. The cells have the potential to make any differentiated cell in the body and thus offer potential development of in cell-based therapies for clinical treatments.

A cell from the inner group of cells of a blastocyst, with the potential to become most or all of the body tissues.

Cells from an early-stage developing embryo, that are able to differentiate into any type of specialised cell (e.g. liver, muscle, nerve etc)

A cell found in early embryos that can renew itself and differentiate into the many cell types that are found in the human body.

Embryonic stem cells (ES cells) are stem cells derived from the inner cell mass of an early stage embryo known as a blastocyst. Human embryos reach the blastocyst stage 4-5 days after fertilisation, at which time they consist of 50-150 cells.
