Biology of stem cells: an overview - PubMed Central (PMC).
The human embryonic stem (hES) cell is characterised as the most plastic stem cell, capable of differentiating into any cell type. HES cells are said to be pluripotent. This means they are able to differentiate into all the germ layers; ectoderm, mesoderm and endoderm. This would achieve the true transdifferentiation that adult stem cells cannot.
Stem cells - How do organisms grow and develop? - OCR 21C.
Definitionnoun, plural: stem cells(1) An unspecializedcellcharacterized by the ability to self-renew by mitosiswhile in an undifferentiated state, and the capacity to give rise to various differentiated cell types by cell differentiation. (2) A cellthat has not yet acquired a special function.
Stem cells - Cellular differentiation - Higher Biology.
A stem cell is the cell that has the capability of reproducing identical cells. They can also split and grow into fully developed cells that are responsible for making up a complete body part like the liver. Pluripotent cells are the types of cells that can grow into any required cell type.
IB Biology 2016 Notes - 1.6 Stem Cells.
Stem cells are undifferentiated cells within the body that have the capability to specialize into any tissue. They are most commonly found in cord blood, bone marrow, organ donations, placenta, and embryos. Stem cells are seen by some as a new miracle treatment, encouraging many countries to invest in their research.
Stem Cell Research Essays: Examples, Topics, Titles.
Stem cells are cells that are obtained from organism and have the ability to differentiate into specialized cells. They divide through mitosis and can self renew into more stem cells. There are two types of stem cells namely embryonic stem cells and adult stem cells (also known as somatic stem cells). Embryonic stem cells are obtained from embryos.
Essay on Cell - Biology Discussion.
Stem cell, an undifferentiated cell that can divide to produce some offspring cells that continue as stem cells and some cells that are destined to differentiate (become specialized). Stem cells are an ongoing source of the differentiated cells that make up the tissues and organs of animals and plants. There is great interest in stem cells because they have potential in the development of.
Using human stem cells - Cell division - AQA - GCSE.
Stem cells are cells that have not undergone differentiation. A cell which has not yet become specialised is called undifferentiated. An embryo develops from a fertilised egg. All of the cells in.
Argumentative The essay Example: The stem The cell.
Stem cells are cells in animals that can continuously undergo cell division. There are two types of stem cell: Embryonic stem cells - These are found in an early embryo. These cells are able to.
Stem Cells and Their Types: (Essay Example), 2317 words.
Stem cells are cells that are not fully differentiated but have the ability to divide and differentiate into different types of cells (e.g. one stem cell can differentiate into a blood cell, a liver cell or a kidney cell).

Stem cell issue: Stem Cell Research: The Ethical Issues.
Stem cells comprise a small subpopulation of a given tissue. Stem cells are ultra-structurally unspecialized, with a large nuclear-to-cytoplasmic ratio and few organelles. Stem cells can be pluripotent. Stem cells are slow cycling but may be induced to proliferate more rapidly in response to certain stimuli.

Stem cells can divide to produce new cells, which can then divide into different cell types. They therefore have the potential to be transplanted into patients to treat medical conditions and.
