Therapeutic Cloning

THERAPEUTIC CLONING

What Is It?

Therapeutic is the making of embryonic stem cells that are used for replacing or repairing damaged tissues or organs.

Disadvantages

Process

Therapeutic cloning is done by inserting a diploid nucleus from a body cell into an eagg cell whose nucleus has already been removed. If the stemcells, from the blastocyst that are made from the egg, were implanted into a uterus, it could produce a clone of the nucleus that was put into the egg.

Advantages

Therapeutic cloning can help treat a disease the patient suffers from by replacing injured of diseased tissues. Furthermore, you can also find out more about molecular causes of diseases by studying the cloned embryos from cells of animals or humans with different diseases. And lastly, these cells can also be used as tools to test new therapeutic drugs.

Due to a close resemblance between stem cells and cancer cells, some experts don't fully trust and support therapuetic cloning. It has been shown that after 60 cycles of cell division, stem cells can form mutstions that could lead to cancer. This is unsafe and before stem cells are used to treat human diseases, the relationship between stem cells and cancer cells must first be clearly understood. Theoretically, therapeutic cloning can be used to treat human disease. However, their low quantitiy and limited potential for development are drawbacks.

Regulations

YASHMIT LEPCHA

UNITED STATES− Embryonic stem cell research, therapeutic cloning and reproductive cloning are legal as there is currently no federal regulation or policies overseeing it.− Some individual states have made their own laws against reproductive and/or therapeutic cloning.

UK, SWEDEN, BELGIUM− Embryonic stem cell research and therapeutic cloning are permitted, but reproductive cloning is banned.− Therapeutic cloning is regulated by Human Fertilization and Embryology Authority (HFEA) in order to understand the development of embryos and to develop treatments for serious disease. (UK)

CANADA− Embryonic stem cell research is permitted, but reproductive cloning and therapeutic cloning are banned.

CHINA, INDIA, JAPAN, SOUTH KOREA, THAILAND, VIETNAM− Embryonic stem cell research and therapeutic cloning are permitted, but reproductive cloning is banned.

Ethics

The ethical issues related to therapeutic cloning is the fact there is tampering with human embryos in the test tube. Several people might not like this and disagree with therapeutic cloning since they believe collecting embryonic stem cells is wrong no matter what the advantages humans could get from it.

Advances

Stomatic cell nuclear transfer (SCNT) is a technique used in therapeutic cloning where the nucleus of a donor cell is transfered to an egg cell whose nucleus has already been removed. This creates embryos that form to become almost genetically identical to the donor individual. And for the first time, a team of scientists has used SCNT to make human embryonic stem cells (hESCs). This event opens up new ways for using stem cells in order to understand pattient-specific causes of diseases and develop personalised therapies.
