Differentiated Cells Cells that are specialized for a particular function (i.e. heart muscle or blood cell) and do not maintain the ability to generate other kinds of cells, or revert back to a less specialized cell (like stem cells

EG Cells Embryonic germ cells . These cells are found in a specific part of the embryo/fetus called the gonadal ridge, and normally develop into mature gametes . Related Topics: Genetics

Primordial Germline Cells The source of embryonic germ cells . In normal development, these are the cells that give rise to eggs or sperm. Contributed by: AAAS/DoSER Related Topics: Genetics

Somatic Cells Cells from the body that compose the tissues, organs, and parts of that individual other than the germ (sex) cells. Related Topics: Genetics Contributed by: BU Search

Totipotent Stem Cells Stem cells which are capable of forming every type of body cell. Each totipotent cell could replicate and differentiate and become a human being. All cells within the early embryo are totipotent up until the
