This shows that the real concern of opponents of stem cell research is the ethics behind the process that can be likened to abortion.
Advantages of Embryonic Stem Cell Research By Mike Crystal; Updated April 24, Research on embryonic stem cells, or ESCs, is an attempt clarify and find treatments and cures for human diseases using unique cells created with modern biochemical methods.
Potential rejection In the case of embryonic cells, the cells that will be used on one human being will be derived from another. Another disadvantage to using embryonic stem cells is the fact that we do not currently have a complete understanding of them.
Some argue that stem cell research in the far future can lead to knowledge on how to clone humans. Unfortunately, these too are unknown until someone receives medical trials and suffers through the negative results of the treatment used. Embryonic cells are undifferentiated cells which can be used in almost all parts of the body for medical purposes.
Studying these cells would likely cause progress in cancer research. Stem cells are distinguished from other cells on the basis of their versatility -- they are unspecialized and can develop into many different cell types depending on their physical environment and the kinds of artificial stimuli they are given.
ESCs from later divisions are multipotent, which means that they can become any type of cell, but not an entire organism. Some would prefer to keep their embryos in storage but do not wish to pay the fee that is required to do so, resulting in discarded embryos.
ESCs, in contrast, are grown in vitro -- that is, in test tubes, such as from embryos destined for artificial insemination procedures. Scientists believe that tissues derived from embryonic and adult stem cells may differ in the likelihood of being rejected after transplantation.
Embryonic cells within the first several divisions are totipotent, meaning they can become anything any type of cell or even develop into a whole organism.
Embryonic stem cell research reduces the number of these embryos being destroyed deliberately. Adult stem cells, and tissues derived from them, are currently believed less likely to initiate rejection after transplantation.
Compared to adult stem cells, ESCs have a wider and ever-expanding range of applications. This is an important distinction, as large numbers of cells are needed for stem cell replacement therapies.
Scientists do this by controlling the conditions in the culture medium in which the ESCs are grown and kept. That is, when the cells come from the brain, it will only generate a similar type. This represents a significant advantage, as immune rejection can be circumvented only by continuous administration of immunosuppressive drugs, and the drugs themselves may cause deleterious side effects.Advantages of Embryonic Stem Cell Research By Mike Crystal; Updated April 24, Research on embryonic stem cells, or ESCs, is an attempt clarify and find treatments and cures for human diseases using unique cells.
Advantages and Disadvantages of Embryonic Stem Cells. OccupyTheory. on 4 February, at one of the largest benefits associated with embryonic stem cells is that they offer an array of medical possibilities that you can use to your advantage.
Human embryos must be destroyed in the process of collecting these. 9 Main Advantages and Disadvantages of Stem Cell Research. List of Pros and Cons; As previously mentioned, embryonic stem cells are derived from human embryos.
Adult stem cells, on the other hand, are undifferentiated cells that are found throughout the body and multiply by cell division so they can help replenish dead cells and repair. List of Disadvantages of Embryonic Stem Cell Research.
1. It results to taking life.
Despite the embryos used coming from unwanted types used for in vitro fertilization, critics still argue that these embryos are already human beings. Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies.
One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become.
The main disadvantage with embryonic stem cells is the way that they are ac quired. Since human embryos are destroyed during the process of harvesting embryonic cells, this makes the research unpopular with those that believe human life begins at conception and that this life is being destroyed.Download
