The source of red and white blood cells are undifferentiated cells called stem cells. Currently , a great controversy exists over the source and use of these cells for research and medical purposes. What is the nature of the controversy? What kinds of abnormalities are associated with stem cells ? To what medical purposes might these cells be used?
Homework Answers
The stem cell controversy involves the development and use of human embryos and focuses on embryonic stem cells. Not all stem cell research involves human embryos. Some abnormalities include using stem cells from the umbilical cord, breast milk, and bone marrow, which are not pluripotent. Stem cells can be used as a renewable source of replacement cells and tissues to treat diseases likes spinal cord injury, stroke, burns, heart disease, diabetes, and rheumatoid arthritis.

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...

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...

Diffraction can be used to provide a quick test of the size of red blood cells. Blood is smeared onto a slide, and a laser shines through the slide. The size of the cells is very consistent, so the multiple diffraction patterns overlap and produce an overall pattern that is similar to what a single cell would produce. Ideally, the diameter of a red blood cell should be between 7.5 and 8.0 μm. If a 633 nm laser shines through...

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...
