Stem cell tech
Dr. James Thomson, and Dr. John Gearhart Human first cultured embryonic stem cells in 1998. Studies done on test animals indicated that it may be possible to manipulate stem cells to produce certain desired cells. Stem cells are unspecialized cells that are the building blocks for all other specialized cells. Stem cells fall into two different categories Pluripotent, and Multipotent. Pluripotent cells are embryonic stem cells, they bring about the bases for many different types of cells. From the pluripotent stem cells, multipotent stem cells are produced, which are more specialized. This process continues and the cells become more specialized until they become specific cells of the body. This technology will be very beneficial to human kind because, when mastered, entire organs could be gown to replace damaged ones.Dr. Thomson obtained embryos from In Vitro Fertilization clinics and isolated the inner cell mass of the embryos at the while they were in the blastocyst stage. He then cultured the isolated
Thanks to the research of doctors such as Dr. Soon it will be possible to repair or replace damaged organs using stem cell technology. Gearhart used fetal tissue from terminated pregnancies specifically he used the cells of the fetus that were going to be the reproductive organs. The results of this procedure is a cell with the potential to develop into a fully functional organism. Using the cultured cells, and an egg cell that has had it nucleus removed, researchers then fused the two. These altered cells are grown in a lab, where they develop into embryos that can be cultured to make embryonic stem cells, from which new organ cells can be produced. The technology is still new and though it will take many years of research to com to a point of mastery, but when that day comes it will be appreciated but many and mark a new chapter in the progression of mankind as a species. These possibilities will be beneficial to the entire populous and will create a higher and more enjoyable quality of life. Using samples from the person with the damaged organ the genetic material would be removed and injected into donated human eggs (from which the chromosomes have been removed). CONCLUSION Stem cell technology is a relatively new field with great an uplifting possibilities. Gearhart and many others this frontier technology and the benefits that will results from it, will eventually be a reality. By using stem cells new organs could be grown and used as replacements. It will then become possible to create desired, cells and tissues to replace damaged ones in humans. Gearhart obtained his cells differently. The new drugs could be tested on a variety of cells created by stem cells.
