The difference between embryonic and adult stem cells is that a.Embryonic stem cells are normally present during development, adult stem cells are only present when gene therapy is used to induce them to form. b.Both adult stem cells and embryonic stem cells can be treated with growth factors to become any tissue type in the body. c.None of the above. d. Embryonic stem cells are pluripotent, adult stem cells might be pluripotent OR multipotent. e.Adult stem cells are multipotent, embryonic...
please answer this post and ask one question regarding this post Embryonic stem cells are a type of cell that derive from embryos. This process usually happens though in vitro fertilization and then donated to research with consent of the donor. These cells are useful for research and can be used to “regenerate and repair damaged tissue, some current therapies such as bone marrow transplantation already make use to stem cells and their potential for regeneration of damaged tissues” (Kohl,...
Cloning Human Embryonic Stem Cells Cloning is now possible by inserting a skin cell from a baby into an unfertilized human egg that has had its own DNA removed. This produces a blastocyte (an undifferentiated embry onic cell), which includes stem cells identical to the baby's. With this technique it is possible to make genetically identical embryonic stem cells from any cell in the human body. This would remove the need to harvest these cells from existing embryos. Theoretically these...
Embryonic stem cells are undifferentiated “blank” cells that can form into any of the tissues present in humans. This makes them all-purpose cells. Because they can form any tissue, harvesting stem cells has become something similar to the holy grail, but harvesting them is fraught with great controversy. Stem cells have two important properties. If they are left in the dish, they will continue to multiply and form more stem cells. If they are placed in different growth conditions, they...
"Stem cells are undifferentiated, primitive cells with the ability both to multiply and to differentiate into specific kinds of cells. Stem cells hold the promise of allowing researchers to grow specialized cells or tissue, which could be used to treat injuries or disease (e.g., spinal cord injuries, Parkinson’s disease, Alzheimer’s disease, diabetes, strokes, burns)." (Slevin, 2010) Choose ONE of the following issues and post to its thread with supporting evidence. 1. Discuss what you feel are the potential benefits of...

Consider a spontaneous mutation in the gene HER2, a tumor suppressor involved in cell cycle control Mutations happen at a rate of about 1 error per 109 bases per generation. A spontaneous deleterious mutation must occur in HER2 specifically, and not in another gene. The likelihood that a spontaneous mutation is deleterious and could lead to cancer depends on the number of mutable bases in HER2, the fraction of bases that will affect the function of HER2, and that both...
