Answer #1

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.

    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...

    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...

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...

    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...
