Kiara Rawls PSYC 2314 Kerstin Brooks June 12, 2018 Stem Cells Cells with the ability to divide for indefinite periods in culture and give rise to specialized cells are called stem cells. Stem cells serve as an internal repair system, dividing themselves without limit to replenish other cells. However, the person or animal must be alive. Division of the stem cell allows each new cell to remain a stem cell or become another type of cell (e.g. muscle cell, red blood cell, or brain cell). Two characteristics distinguish stem cells from other cell types. Stem cells are unspecialized cells capable of renewing themselves through cell division is the first characteristic. Second, under certain physiologic or experimental conditions, they can be induced to become tissue or organ specific cells with special functions [Nat18]. Scientists recently, primarily started working with two kinds of stem cells from animals and humans: embryonic stem cell and non-embryonic “somatic” or “adult” stem cells. Our main focus is embryonic stem cells. These primitive cells derived from a 5 day embryo that are capable of dividing
