Stem cells are specialized cells of animals and plants that have the ability to grow and divide by mitosis. Cell division results in self-regeneration as well as differentiation. This means that stem cells can maintain their characteristic as stem cells (self-regeneration), but also change into a different cell type (differentiation).
A cell which can divide into a copy of itself and a differentiated progeny.
An unspecialized cell that gives rise to differentiated cells. In the bone marrow, cell from which all blood cells derive.
"Mother" cell from which all types of blood cell originate
A "generic" cell that can make exact copies of itself indefinitely. In addition, a stem cell has the ability to produce specialized cells for various tissues in the body, such as heart muscle, brain tissue, and liver tissue. Scientists are able to maintain stem cells forever, developing them into specialized cells as needed. There are two basic types of stem cells. The first type is the embryonic stem cell, which is obtained from either aborted fetuses or fertilized eggs that are left over from in vitro fertilization. Embryonic stem cells are useful for medical and research purposes because they can produce cells for almost every tissue in the body. The second type is the adult stem cell, which is not as versatile for research purposes because it is specific to certain cell types, such as blood, intestines, skin, and muscle.
An undifferentiated precursor cell that retains the ability to give rise to a variety of cell types. In the nervous system, stem cells can give rise to various neuron subtypes and to glial cells.
The cell in the bone marrow that gives rise to the blood cells. The stem cells produce both red and white blood cells. If the stem cells are destroyed during chemotherapy then there will be no white blood cells to combat infection, which may be fatal. If some stem cells can be removed prior to chemotherapy, then huge doses of chemotherapy, that would otherwise be fatal, can be given and the stem cells replaced after the chemotherapy. It is called a stem cell because it has the ability to become any of the blood elements. The other cells in the bone marrow have lost this ability and can make only a specific type of blood cell element.
A cell with the potential to become any type of specialised cell, i.e. an undifferentiated cell. Embryo cells are mainly stem cells.
a precursor cell in the bone marrow from which all blood cells are derived.
Cells that can give rise to other types of cells; they are produced both during embryonic development and in the adult body. Embryonic stem cells begin with the ability to become any cell type, and quickly differentiate into cells committed toward a certain type of tissue, e.g., blood, skin, or neural stem cells. These are termed multipotential stem cells, because they further divide into cells with a particular function, such as red and white blood cells and platelets. Multipotential cells are also present in adults. Stem cells are capable of dividing for indefinite periods in culture.
A cell that has the ability to divide for indefinite periods in culture and to give rise to specialized cells.
A self-renewing cell that divides to give rise to a cell with an identical developmental potential and/or one with a more restricted developmental potential.
A cell capable of extensive proliferation, generating more stem cells and a large clone of differentiated progeny cells, as in the formation of red blood cells.

Cell that gives rise to a lineage of cells. Particularly used to describe the most primitive cells in the bone marrow from which all the various types of blood cell are derived.

A young, precursor cell that originates in the bone marrow and serves as the “parent cell” to all other blood cells in the body. Red blood cells, white blood cells and platelets all evolve from stem cells.
A special type of cell that is immature (not fully formed). A stem cell can become any of the three types of blood cells—a red blood cell, white blood cell, or platelet depending upon what the body needs. Most stem cells are found in the bone marrow, but a small number are found circulating throughout the body in the bloodstream. These are called peripheral stem cells.
A cell that produces other kinds of cells. Blood-forming stem cells produce red blood cells, white blood cells and platelets.
Stem cells give rise to normal blood components including red cells, white cells and platelets. Stem cells are normally located in the bone marrow and in the blood and can be harvested for a transplant.
Unspecialized cells that renew themselves for long periods through cell division. Under certain physiologic or experimental conditions, they can be induced to become cells with special functions such as the beating cells of the heart muscle or the insulin-producing cells of the pancreas. Stem cells are the foundation of every cell and tissue in the body.
The “parent cell.” Every type of blood cell in the body begins its life as a stem cell. The stem cells then divide and form the different cells that make up the blood and immune system. Stem cells are found in both the bone marrow and circulating blood.
Immature blood cells that develop into new red and white blood cells, and platelets as they mature. They are located in the bone marrow and blood and can be donated and transplanted. Jump to Top

A primitive, unspecialized cell that has the capacity to develop highly specialized function when grown in the appropriate environment and treated with specific growth factors.

"Mother" blood cells from which several different types of blood cells evolve.
An undifferentiated, primitive cell in the bone marrow that has the ability both to multiply and to differentiate into specific blood cells.
a cell that gives rise to other cells; usually less differentiated than the cells of the tissue.
Undifferentiated cell that is able to develop into other cell types. This ability allows stem cells to act as a repair system for the body, replenishing other cells. Found in embryos and some organs in adults.
Stem cells are cells that have not differentiated (turned into) cells with a specific function. Stem cells can be manipulated by environment to differentiate into liver cells, blood cells, brain cells and so on. Stem cells are potentially useful in treating many diseases.

cella - compartment]. An undifferentiated cell that is mitotically active in either replacing dying body cells (somatic stem cell) or producing gametes (germinal stem cell).
special cells that have the ability to grow into any one of the body's more than 200 cell types. Unlike mature cells, which are permanently committed to their fate, stem cells can both renew themselves and create cells of other tissues.
A mitotically active somatic cell from which other cells arise by differentiation.
a cell from which all other blood cells originate; also called a pluripotent stem cell
Cell from which platelets, red blood cells, and white cells grow in the bone marrow.
A relatively undifferentiated cell in any tissue responsible for replenishing cells lost from a tissue through normal wear and tear, in the case of adult stem cells, or responsible for virtually all of a fetus's cells, in the case of embryonic stem cells; characterised by being able to replicate (through mitosis) seemingly for ever, either in the body or in tissue culture, without wearing out the ends of the chromosomes. Embryonic stem cells are controversial because they are derived from human embryos, sometimes by the process of somatic cell nuclear transfer, which involves creating embryos or embryo-like forms of a kind that could be used for reproductive cloning. The word stem comes from analogy with the stem of a plant giving rise to branches and further branches, representing the ever-increasing number of different paths a stem cell can differentiate into.
A (relatively) undifferentiated cell that is capable of dividing and specializing into one or more types of somatic cells. The most fundamental types of stem cells, embryonal stem cells, express telomerase and have no Hayflick limit. These cells are pluripotent -- they can specialize into any type of cell in the body.
A cell from which other types of cells develop. Blood cells develop from blood-forming stem cells.
An unspecialized cell that gives rise to a specific specialized cell, such as a blood cell. They serve as the natural repair system for the human body. There are many different types of stem cells; not all of them arise from embryos.
