The Underlying biology of Chimera Stem Cells: 1. The blastocyst helps make the different parts of the embryo inner cell mass, which in turn helps to make the embryo proper 2. The trophectoderm and primitive endoderm make extra embryonic structures that support the growth of the embryo 3. Two to eight cell stage embryos are used for making chimeras, since they aren’t committed to helping a particular cell lineage and could possible make the inner cell mass or trophectoderm 4. If two diploid eight…
million with cancer, 4 million with Alzheimer’s disease, along with many others. A stem cell is an undifferentiated cell that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. These cells are used for medical research because they can produce new cells to replace damaged tissue in the body. Embryonic…
Regenerative Medicine is a new cutting edge technology in the health care world. Considering this, it has deemed a game changer in the everyday lives of many. The people who are suffering from conditions that can be beyond repair would benefit from this type of regenerative medicine. Stem Cell specific Regenerative Medicine has been drawing great attention, due to the positive outcomes of the use of stem cells in repairing bone, tissues, organs and much more. The goal is to point out and…
action Skin is a multilayered organ with the ability to protect the organ¬ism against external aggressions. The skin consists of three main layers including epidermis, dermis and subcutis that are responsible for its high turnover capacity in repairing different injuries. Similar to other tissues, the stem cells existed in skin tissue play an important role in regulating the balance between cell loss and cell division [22, 23]. siRNA therapeutics are potent alternative for skin regeneration due…
When multi-cellular organisms develop, cells must differentiate to form specialised cells, which have a diverse range of functions, these then give the organism the necessary assistance to survive and eventually live. A stem cell is a cell which is undifferentiated and not yet specialised, although it has to capability to form or configure itself into any other type of cell. Fertilised embryos are called zygotes which then produce pluripotent embryonic stem cells, a prerequisite to the survival…
done using human tissues grown from stem cells contained in the intestine and the results were the same--a fully functional small intestine. The small intestine also had the ability to absorb sugars, and even tiny or ultra-structural components like cellular connections. What this means is that the intestine could replace intestinal transplantation, and offer a therapeutic alternative and could potentially solve its largest challenges -- donor shortage and the need for lifelong…
Although scientific research has come a long way since the beginning of time, it has not done so without some kind of controversy. From Biopsychiatry to the Tuskegee Experiments, it seems as though there cannot be any scientific breakthrough without some kind of ethical issue. Stem cells are another example of a controversial treatment that is taking the medical field by storm. Although it is very controversial, it’s results are truly amazing and beneficial to anyone who is willing to give it a…
cells can also help males and females with fertility issues. Understanding these cells during development can help scientists understand abnormal cell development that leads to many harmful and life threatening problems (NIH). Cell Differentiation. N.d. Intech. Web. 4 Apr. 2015. http://www.intechopen.com/books/stem-cells-in-clinic-and-research/stem-cell-therapy-for-neuromuscular-diseases. In conclusion, embryonic stem cells are undifferentiated cells that come from human…
Scientists first discovered stem cells in the early 1900s. During this discovery, the scientists discovered that some cells had the capability to turn into blood cells, a completely different type of cell. These specific types of cells were classified as stem cells. Stem cells are known as undifferentiated cells, which means they do not have a specific function yet. Stem cells, since undifferentiated, are capable of becoming a specific type of cell such as a blood cell or a muscle cell. Unlike…
Ethical Responsibilities of Embryonic Stem Cell Research In the two-thousand nine movie, My Sister’s Keeper by Jeremy Leven, a family is struck with tragedy when their daughter, Kate, is diagnosed with Leukemia and not expected to live past the age of five years old. The doctor covertly introduces the topic of in vitro fertilization to assure a perfect match to the little girl. The procedure was successfully performed, and the parents have a little girl who they named Anna. Anna has given…
