Introduction This is a report on stem cells and the stem cell bank The aim of this report to overview stem cell research, including stem cell banks and pitched at general readers of non scientific background. 2 Summary This report consists of brief information on what stem cells are and their sources, the UK Stem Cell Bank and the controversy surrounding embryonic stem cell research. The main point of this report is the potential for treatment of illness using embryonic stem cells. 3. What are Stem Cells? Stem cells are unspecialized (cells of no particular function) that reproduce themselves continually and under the right conditions develop from simple to more complex cells which are specialized to perform particular functions, this is termed cell differentiation. ...read more.

and because they are found in such small amounts making them difficult to identify and isolate the use of them is limited. 3.2 Core Blood Stem Cells Core blood stem cells are a source of adult stem cells which are found in the blood of the placenta and umbilical cord which is left over from birth, and have been used to treat Leukemia, Hunters Syndrome and many other conditions that usually occur in children (ref.www.wikipedia.com). 3.3 Embryonic Stem Cells Embryonic stem cells occur in the very early (week old) embryos of humans before it implants in the uterus and have the ability to develop into all types of specialized cells, this is called "pluripotent". Embryonic stem cells are created from cloned embryos, usually left over and donated by IVF patients. A mass of cells descending from the original cell, which share genetic characteristics are created and batches are then separated from the mass used by researchers to develop treatments for illness (these masses are called cell-lines). ...read more.

Conclusion

The UK Stem Cell Bank stores derived stem cell lines of adult, fetal and embryonic cells and distributes them to researchers in order to help and support the continuation stem cell research of which eventually will revolutionize the treatment of human illnesses and diseases of which there is currently no cure. The UK Cell Bank introduced strict safety measures to ensure that embryonic stem cells are properly used and handled. 6. Controversial Issues There are a number of groups who are opposed to embryonic stem cell research and it involves the destruction of human embryos. Pro Life groups consider it abortion and therefore murder, and believe the cloning of the embryos ethically and morally wrong. They say adult stem cells can produce the same results as scientist believe can be achieved by embryonic stem cell research and development, that research into adult stem cell should be intensified and financial backing increased. Scientists argue that "Embryos used in research would normally be discarded or frozen indefinitely if not used in research" (ref: www.wikipedia.com). ...read more.

  1. The Science of Stem Cells

    Understanding the events that occur at the first stages of development has potential clinical significance for preventing or treating birth defects, infertility and pregnancy loss. A thorough knowledge of normal development could ultimately allow the prevention or treatment of abnormal human development.

    - Kinetochores that are specialized regions in the centromeres of chromosomes, attach to a type of microtubule called kinetochore fibres. - The kinetochore fibres "interact" with the spindle polar fibres connecting the kinetochores to the polar fibres. - The chromosomes begin to migrate toward the cell centre.
