A fantastic question! It's not just stem cells you need to consider, but indeed any type of organ transplant or tissue donation. Another person, unless they are your identical twin, will have DNA different from your own. The reason lung transplants or bone marrow transplants actually work is because you are substituting dodgy tissue for healthy tissue. At the same time, you are replacing a gene that has gone wrong by putting in a healthy copy of the gene. That means the DNA in the tissue you've replaced will be different. The rest of your body won't change. If you do a bone marrow stem cell transplant for someone with leukaemia, the cells that you will have inside your bone marrow will come from your donor. Therefore, they will also be genetically identical to the donor. This means that a man who receives a bone marrow transplant from a lady will have bone marrow cells that have two X chromosomes. Sometimes people can even see a change in their blood group.
Low stem cell yield is a significant issue following cord stem cell transplant for haematological conditions. Discuss the methods that have been implemented and those that are currently under investigation to improve outcome following cord stem cell transplantation in relation to improvements in the CD34+ cell dose provided.
15 . Which of these immunopathologies could be treated with a stem cell transplant? a. arthus reaction b. SCID c. anaphylaxis d. a and b only e. b and c only
Suppose that your bacterial cell contained a plasmid. When you isolated "genomic" DNA, would you expect to obtain the plasmid DNA along with the chromosomal DNA? Explain.
Would a transit amplifying cell be suitable to become the stem cell of the tissue in the event of injury of the adult stem cell?
a nurse is providing teaching for a client who is scheduled for an allogeneic stem cell transplant. which of the following information should the nurse include?
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...
Stem cell therapies -> requires multiple infusions of stem cells. Why do you think there is a need to have a number of treatments for effective therapy?
3. Why is human embryonic stem cell research strictly limited? Discuss your thoughts on human ESC research, would you support it or oppose it and why?
a. You cut a gene out of the DNA of a eukaryotic cell and insert it into the DNA of a bacterial cell. Much to your dismay you find that the protein product you want is not produced by the bacteria but instead a much larger disorganized protein is produced. Explain what is going on. b. Your lab mate claims to have found a mutation in the serine tRNA synthetase that causes serine amino acids to be linked to a...
a) You cut a gene out of the DNA of a eukaryotic cell and insert it into the DNA of a bacterial cell. You find that the bacteria do not produce the protein you wanted but instead, a much larger disorganized protein is produced. Explain what happened. b) Your teammate claims to have found a mutation in the serine tRNA synthetase that causes serine amino acids to be linked to a tRNA with a UAA anti-codon. Is this possible? If so,...
