Properties of human embryonic stem cells, developed from surplus embryos after in vitro fertilization, include:
(A) can replicate themselves to provide a pool of stem cells
(C) can be injected into a whole organism (human) without the risk of rejection
(B) can be differentiated into other cell types
Both A and B are correct
All answers are correct
Answer
Option E is the right answer because all of the options are right as human embryonic stem cells can be differentiated into a pool of stem cells as well as other terminal cells and can be injected without the risk of rejection.

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...
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,...
Which of the following statements regarding embryonic stem (ES) cells are true? A. They can only generate a very limited number of cell types. B. They can theoretically give rise to all types of cells in an organism. C. They are highly specialized. D. They are pluripotent. E. Harvesting them from human embryos raises ethical and political issues.
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...
Genetic variability is A) achieved through meiosis B) due to both crossing over and the law of independent assortment. c) why two siblings are uniquely different from each other. D) All of the above are true. 16. Given the image on the right of the onion root tip col, which of the following is NOT TRUE? A) The most common cell cycle stage is anaphase. B) All the stages of mitosis are depicted in the image. c) There is one...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
