Somatic Cells
A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent.
somatic cell - any cell in the body that is not a germ cell (reproductive cell).
spindle fibers - protein structures which move the chromosomes during cell division.
Somatic Cell Hybrids: Cultures and DNA. Human/rodent somatic cell hybrids are available as cultures nd purified DNA. For details on their mapping panel, see box.
Somatic cells: Any cell in the body except sex cells.
Template: a single DNA strand that serves as pattern for building a new second strand.
Thymine (T): A base; one of the molecular components of DNA and RNA. Always bonds with adenine (T-A).
somatic cell
[Gk. soma, body]
Any cell in a multicellular organism except a sperm or egg cell.
somatic nervous system ...
somatic cell A cell that is not or will not become a gamete; the cells of the body.
somatic senses All senses except vision, hearing, taste, and smell; include pain, temperature, and pressure.
Somatic cells: Cells of body tissues other than the germline.
Splicing: See gene splicing.
StarLinkTM: An insect-resistant variety of corn that was approved for animal feed only, not labeled for human consumption.
Somatic cell A cell which is not on the lineage from which gametes are made. (see germline)
Somatic cell genetics The study of genes using hybrids (fusions) between the somatic cells of different species.
Somatic cell. Any nongerm cell that composes the body of an organism and which possesses a set of multiploid chromosomes (diploid in most organisms). (See Gamete, Somatic cell gene therapy.) ...
somatic cell
any of the cells of a plant or animal except the reproductive cells.
somite
A serial segment of the animal body.
[edit] Somatic cell gene therapy
In somatic cell gene therapy, the gene is introduced only in somatic cells, especially of these tissues in which expression of the concerned gene is critical for health.
Somatic cell
Any cell in the body except gametes and their precursors.
Related Terms:
Gamete
Mature male or female reproductive cell (sperm or ovum) with a haploid set of chromosomes (23 for humans).
somatic cell Ordinary body cell; pertaining to or characteristic of a body cell. Any cell other than a germ cell or germ-cell precursor.
Most somatic cells of the body cease to express telomerase. However, cells genetically manipulated to express telomerase long after they should have stopped, avoid replicative senescence. Germ cells and some stem cells continue to express the enzyme.
Problem 12: Somatic cell hybrids
By examining a number of somatic-cell hybrid lines for enzyme activities and their human chromosome constitution, scientists can determine
A. ...
archeocyte - somatic cell of sponge that can differentiate into all three other cell types of the organism.
aster - radiating formation of microtubules at each pole of a spindle apparatus, formed during mitosis; comes from word meaning "star.
See Somatic cell. Germ cell (germ line) gene therapy. The repair or re- placement of a defective gene within the gamete-forming tissues, which produces a heritable change in an organism's genetic constitution. GMO. Genetically modified organism.
Barr body -- the condensed single X-chromosome seen in the nuclei of somatic cells of female mammals. base pair a pair of hydrogen-bonded nitrogenous bases (one purine and one pyrimidine) that join the component strands of the DNA double helix.
Later a mutation occurs in the second copy of the gene in a somatic cell. In that cell both copies of the gene are mutated and the cell develops uncontrolled growth.
This applies not only to the somatic cells but to the primitive ova and their descendants. For the purpose of illustrating the process of maturation a species may be taken in which the number of nuclear chromosomes is four (Fig. 5).

In theory it is possible to transform either somatic cells (most cells of the body) or cells of the germline (such as stem cells, sperm and eggs).

Telomerase is usually found in cells involved in the production of gametes. It is not normally found in somatic cells.
Cyclin-Dependent Kinases
Some cells stop dividing in G1; others stop in G2.
Diploid number (2n): The full complement of chromosomes in a somatic cell (or a sex cell before meiosis). In humans, the diploid number is 46.
[Gr. meiosis - reduction]. Two consecutive nuclear divisions whereby the resultant daughter nuclei contain half the chromosome complement of other somatic cells; occurs at time of gametogenesis. Synonym: reduction division.
