Compare And Contrast Stem Cell And Stem Cells

Stem Cells: Adult vs. Fetus

Stem cells are multicellular organisms, they are a unique part of the body, considering they can renew themselves, and can also make a variety of other kinds of cells. There are multiple types of stem cells, such as adult or somatic stem cells, and embryonic stem cells. Stem cells are currently being used for scientific medical research, but the only stem cell treatments that have been proven to work well so far involve tissue stem cells, mainly those found in bone marrow and skin. However, significant technical hurdles remain that can only be overcome through years of intensive research.
Adult or somatic stem cells exist throughout the body after embryonic development and are found inside of different types of

The embryos are usually extras that have been created in IVF (in vitro fertilization) clinics where several eggs are fertilized in a test tube, but only one is implanted into a woman (Crosta, Paragraph 3). The blastocyst consists of an inner cell mass (embryoblast) and an outer cell mass (trophoblast). The outer cell mass becomes part of the placenta, and the inner cell mass is the group of cells that will differentiate to become all the structures of an adult organism(Crosta, Paragraph 4). In a healthy pregnancy, the blastocyst stage continues until implantation of the embryo in the uterus, at which point the embryo is referred to as a fetus. This usually occurs by the end of the 10th week of gestation after all the primary organs of the body have been created (Crosta, Paragraph 5). Human embryonic stem cells are the cells from which all 200+ kinds of tissue in the human body originate. When stem cells are obtained from living human embryos, the harvesting of such cells necessitates the destruction of the

Skin is particularly rich in stem cells because so much skin is lost through normal wear and tear; you shed thousands, sometimes even millions, of dead skin cells every day. In mild cuts and burns, stem cells work to repair the damaged tissue. But in severe burns the stem cells in the burn area are destroyed, so doctors have to take skin from an undamaged area. The biggest obstacle in performing a skin graft is that, currently, only the burn patient’s own skin works reliably. If doctors try to use skin from another person, the patient’s immune system will eventually reject the graft. However, scientists are working on ways to grow skin that’s genetically compatible with the patient so that, even if the patient doesn’t have enough undamaged skin to use, the burns can still be treated
