In order to examine scientists get embryos in two different way. For countless numbers of couples in vitro fertilization is the only way to have a child. During this procedure, a couple’s sperms and eggs are fertilized in a culture dish. Next, the eggs will develop into embryos, which are then implanted in the female. Nevertheless, embryos are usually frozen and stored for future use.
Since the first “test-tube baby” was born, in vitro fertilization has become a common procedure in fertility treatment. A key issue couples considering in vitro fertilization is the use of their embryos. The woman often produces more eggs than can be used during a single IVF attempt. The extra embryos can be frozen to use in subsequent procedures, or a couple may have them destroyed, kept in storage indefinitely or donated to another infertile couple. Another issue is how many embryos should be placed back in the uterus.
With help of stem cell research, the doctors are now able to provide treatment to patients suffering from leukemia, lymphoma, other blood disorders, and some solid tumors. It is important to know that human stem cells come either from embryos or adult tissue. Embryonic stem cells can be created solely for the purpose of stem cell research or they can be the leftover from other processes, such as from in-vitro fertilization (IVF). Fertility treatments usually result in multiple embryos creation and while only the most viable ones are used, others are left unused which can be either discarded or donated to others needing fertility assistances or even donated for research. The Ethical Issue with Stem Cell Research The embryonic stem cells are particularly easy to extract than the adult stem cells.
Though this is rare it does happen naturally and the two individuals are genetically identical. Artificial embryo twinning copies this separation of a singular embryo into two separate embryos, yet it is done in a laboratory and the embryos are separated manually in a petri dish after the embryo first splits. The two separate embryos are then placed into a surrogate mother where they develop naturally. Somatic cell nuclear transfer produces the same result as artificial embryo twinning, yet it is a different way of cloning. First scientist isolate and egg cell and remove its nucleus.
Scientists have been successful in the areas of cloning before, but a breakthrough in 2013 is helping the area of stem cell usage. There is much controversy over the use of stem cells, but this new technology may help lessen that. Using a technique called “somatic cell nuclear transfer,” researchers cloned a human embryo. Within an embryo are embryonic stem cells, which are unique because of their never-ending list of uses. Stem cells are a crucial part of many new medical research projects because they can be manipulated into producing any type of bodily cell, including more stem cells.
It contains a complete set of the genetic information necessary for the development of a baby. Half of that genetic material comes from the mother, carried in the egg; the other half comes from the father, carried in the sperm cell. That means the baby will have a combination of characteristics from both parents. The next step after fertilization consists of the fertilized cell floating down the fallopian tube toward the uterus, where the cell divides into two. Those two cells then divide to make four, and the division continues.
Unlike a regular cell, which can only replicate to create more of its own kind of cell, a stem cell is pluripotent. When it divides, it can make any one of the 220 different cells in the human body. Stem cells also have the capability to self-renew -- they can reproduce themselves many times over. There are two types of stem cells: embryonic stem cells and adult stem cells. Embryonic stem cells come from an embryo -- the mass of cells in the earliest stage of human development that, if implanted in a woman's womb, will eventually grow into a fetus.
Diseases such as cancer and birth defects are caused by abnormal cell division and differentiation. The idea is to find how diseases come about and find new ways of treating them. This can only be done by looking and understanding stem cells. By understanding stem cells, scientists can begin to... ... middle of paper ... ...can really help cure diseases and repair organs, then this can be one of the biggest breakthroughs in medical history and be ethically right. It will take many years to fully develop stem cell research and to have this option available for all people, but when it is ready for the public, it will be such an boom that will save so many lives.
There is a rich supply of adult stem cells found throughout the body in bone marrow, fat tissue, and even the amniotic fluid that surrounds and protects unborn babies. Embryonic stem cells are derived from human embryos, many times they come from leftover in vitro fertilization efforts remaining in fertility centers.

In the future with advancement in the research of stem cells, doctors will be able to provide treatment for a great quantity of medical conditions. Scientists will continue their research on embryonic and somatic stem cells with the hopes of treating different diseases.
These include embryonic stem cells, adult stem cells, and induced pluripotent cells. Embryonic stem cells are cells that have the potential to produce many different cells in the body.

This could be a medical breakthrough for many patients because this could mean limited hospital stay; Fewer treatments from reoccurring illness caused by damaged tissue and saving them money by decreasing the need for multiple hospital visits. Stem cells are an ongoing research project in which new discoveries are being made about them, and researchers are learning how to use them in new ways.
