We define ASC and ESC as follow:
Adult stem cells: Adult stem cells are undifferentiated cells which reside among differentiated tissue in adult.
Embryonic stem cells: Embryonic stem cells are cells which are found in inner cell mass of embryo.
Fundamental importance of using one over another:
Adult stem cells are multipotent i.e cannot be differentiated into any new type of cells whereas embryonic stem cells are pluripotent i.e it can differentiate in any type of cell. ASCs has more advantage in therapies as it is less prone to develop in a cancer as compare to ESCs based therapies. And also ASCs can be found in different organs of body such as brain, liver, bone marrow, blood etc. whereas in case of ESCs, it is required to have an embryo to extract these cells.

What is fundamentally important about the difference between using embryonic or adult stem cells in scientific...
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...
Discuss the importance of Stem cells in the body and in scientific research. Why is it important for Stem cells to express Telomerase enzyme?
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,...
5. Embryonic stem cells are derived from embryos. They are specifically obtained from eggs that have been fertilized in vitro for an infertile couple in an in-vitro fertilization clinic. These are excess fertilized eggs that are donated for research with informed consent of the donors. Medical researchers believe that stem cells have great potential for helping to repair, even regenerate, damaged human tissue, even nerve tissue. Would a Kantian approve of using human embryonic stem cells for medical research and...
what ethical issues surround embryonic stem-cell research? should the president have limited federal stem-cell research? Are other alternatives such as adult stem cell and placenta as effective? why or why not?
Stem cell research has alternatives to embryonic cells; What is one alternative? 3.

10-14 10-14 Q10. Scientists are divided over value of embryonic stem cells (ESC) and adult stem cells (ASC). Some of the specific scientific concerns include: A. Lack of directed control of ESCs differentiation, potentially leading to uncontrollable teratomas in murine models B. ASCs plasticity and ability to differentiate into other tissues and cells C. Accessibility of ESCs and ASCs cell lines D. ASC transplantation and tissue rejection E. All of the above Q11. Cloning does NOT involve which of the...
14. Embryonic stem cells are useful in research but also characteristics that limit their clinical use. Which of the following is a limiting use characteristic? A. They form teratomas B. They are not present in bone marrow C. They are autologous D. They are multipotent
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...
1. Given DES’s embryonic proliferation of Leydig stem cells, how could this change in hormones lead to testicular cancer? 2. Given DES’s embryonic reduction in Sertoli cells, what do you predict are the effects on fertility in DES sons? Please describe with much detail.
