All About Stem Cells - Science Project: Stem Cells Info What. Definition: Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. Commonly, stem cells come from two main sources: Embryos formed during the blastocyst phase of embryological development (embryonic stem cells) and Adult tissue (adult stem cells.) Why are they important. In many tissues, they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive....   [tags: differentiation, repair, controversy] 1392 words

Adult and Embryonic Stem Cells - Stem cells could be the beginning of a whole new world, but are you for or against it. According to Wikipedia, stem cells are undifferentiated biological cells that can differentiate to become specialized cells. These cells can also divide to produce more stem cells. Scientists have found ways to use these cells to benefit others. There are several places in which these stem cells can be extracted. However, the topic is very controversial because there are two types of stem cells; adult stem cells, and embryonic stem cells....   [tags: destruction of an embryo, unethical] 712 words

Stem Cells - Photo courtesy University of Wisconsin Board of Regents Microscopic 10x view of a colony of embryonic stems cells (The stem cell colonies are the rounded, dense masses of cells.) Meriam-Webster defines stem cells as: an unspecialized cell that gives rise to differentiated cells. This means the can turn into any cells the body is in need of .Their almost limitless potential has made stem cells a significant focus of medical research.

Stem Cells - Abstract 1. The object of this Paper is to provide an independent assessment of the Donaldson Committee's Recommendations in light of the most recent advances in stem cell research. 2. Stem cells should be defined by their ability to renew themselves and diversify into other cell types. 3. There are several readily accessible sources of stem cells. Strict criteria apply to the use of these sources in medical research. 4. Stem cells have wide potential application in medicine. "Adult" stem cells have already been used in the world's first recorded case of successful gene therapy "surgery"....   [tags: essays research papers] 2770 words

Stem Cells - What is a stem cell. Stem cells have the ability to divide for indefinite periods in culture and to give rise to specialized cells. They are best described in the context of normal human development. Human development begins when a sperm fertilizes an egg and creates a single cell that has the potential to form an entire organism. This fertilized egg is totipotent, meaning that its potential is total. In the first hours after fertilization, this cell divides into identical totipotent cells. This means that either one of these cells, if placed into a woman's uterus, has the potential to develop into a fetus....   [tags: essays research papers] 2840 words

stem cells - After a typical delivery the umbilical cord and the blood within it is discarded. Now researchers have discovered that this blood contains valuable stem cells which can be used in the treatment of several blood disorders. Stem cells are simply undeveloped cells that develop into platelets or red and white blood cells. Stem cells will continue to produce blood cells for an indefinite period of time after transplantation.

Stem Cells - &#65279;Science is moving at such a rapid speed these days, between cloning, gene therapy, miracle drugs, exotic therapies, etc. One of the most significant breakthroughs came in November 1998, when two separate researchers successfully isolated stem cells from human embryos and aborted fetuses. Stem cells are primordial cells of a human organism, which are capable of becoming all or most of the 210 different kinds of tissues in the human body. Stem cells have been defined as not fully differentiated yet to be any particular type of tissue or cell....   [tags: advances in Science]

Stem Cells Should Not Be Used Therapeutically - Stem Cells Should Not Be Used Therapeutically A stem cell is a cell in the body that can differentiate into almost any other type of cell in the body. Stem cells come from sites in the bone marrow, as well as the tissues of developing fetuses. The most controversial issue in stem cell therapy is the use of fetuses for their stem cells. Scientists want to clone human embryos, and use the stem cells long before the embryo matures (when it is only about 36 cells). This causes a large amount of unease in society, because people fear that stem cells and therapeutic cloning will lead us into disgusting and horrible experimental practices, as well as therapies....   [tags: Science Health Biology Essays]

Adult and Embryonic Stem Cells Hold Great Promise in Medicine - Stem cells are versatile cells that have great promise in medicine. There are two main types of stem cells: adult and embryonic stem cells. For many years, embryonic stem cells were considered the most useful for research and advancements in medical therapies. Embryonic stem cells are undifferentiated cells that can be prompted to become any tissue in the body. That is why they are considered so important, however, the pluripotence of the embryonic stem cell can also be their downfall. Since these cells can become anything, this also means they can mutate into tumors and other undesirable things....   [tags: research, immune system, transplant] 617 words
