When a couple or individual undergoes in vitro fertilization‚ several embryos are created in the lab to increase the chance of the embryo successfully implanting in the womb of the female. There are various scenarios in which several embryos are left over from the process and are either discarded or donated to scientific research. It seems logical to harness

Embryonic Stem Cell Research Should Be Federally Funded The undifferentiated cells of a human embryo‚ referred to as stem cells‚ hold limitless promise for medical research. When a human embryo consists of not more than 64 cells‚ its cells are able to learn new ways of being. If injected into a diseased kidney‚ they take on many of the properties of ordinary kidney cells‚ and may help the kidney to perform its normal function. This seems to hold for any organ‚ even any kind of cell. (Goldstein)

Many are saying that scientists should not be experimenting with human life. Although an embryo is destroyed in the process of retrieving the cells‚ the research could lead to outcomes that could save many people’s lives. If the embryos are frozen and never touched again‚ then what is the point? They could be used for important medical purposes. Another concern for some people are that this cell research could

Cloning What is cloning? The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity. The copied material‚ which has the same genetic make-up as the original‚ is referred to as a clone. Researchers have cloned a wide range of biological materials‚ including genes‚ cells‚ tissues and even entire organisms‚ such as a sheep. Do clones ever occur naturally? Yes. In nature‚ some plants and single-celled organisms‚ such as bacteria

Most have their own opinion on this topic‚ but if “killing” an embryo can save lives it might be worth it. General stem cell research has been going on for many years‚ but due to cut funding‚ advancements have been inhibited. It was cut because embryonic stem cells research is considered unethical‚ but embryonic stem

The Ministry of Health’s role is basically to lay the policy and the direction of health services in the country and to show the commitment of the Government‚ and the powers-to-be‚ that health is of utmost importance in nation building. And the role of the ministry is to enforce regulations and be the regulator. Imagine if there is no Ministry of Health‚ anybody can make the claim that their product is the best for health; anybody can set up a hospital. Nobody to regulate the quality of the workforce

Doctors fertilize more than one egg‚ to keep a surplus stock of embryos for future use‚ is even this ethical? What would happen if one of those embryos died? Embryonic stem cells are taken from human embryos. The majority of these stem cells develop from eggs that have
