Stem+Cell+Research

=Stem Cell Research = What is a stem cell? hey are unspecialized cells capable of renewing themselves through cell division (2) Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. (2) Advantages of stem cell research: • Healthy cells (stem cells) replace dead cells in the organism(1) • Stem cells can renew themselves through cell division(1) • These stem cells can transform into any other type of cell that might help make cures for really dangerous diseases. (1)
 * T
 * They can replace worn out tissues in a few organs or bone marrow

Disadvantages of stem cell research: • Embryos die through the process of obtaining stem cell(1)

Describe how genetic engineering is used within Stem Cell Research Stem cell research is a new technology that takes primitive human cells and renews them into any of the 220 varieties of cells in the human body, for example blood cells and brain cells. On the other hand, genetic engineering is the human manipulation of an organism's genetic material in a way that it does not occur under natural conditions. It is used within stem cell research because it has the ability to uncover treatments and possibly even cure diseases. Also, stem cell research main problem is that it can also be used for human cloning where the man manipulates the genetic material. (1)
