Question: Which somatic cells must be used for gene therapy?

Somatic gene therapy is the transfer of genes into the somatic cells of the patient, such as cells of the bone marrow, and hence the new DNA does not enter the eggs or sperm.

What is somatic gene therapy used for?

Somatic cell gene therapy involves the placement of a human gene into a living person’s somatic cells—cells that do not produce the eggs and sperm that in turn produce the next generation. Somatic cell gene therapy would aim to cure a disease only in the patient, not in the patient’s descendants.

What is a difference between genetic therapy that is somatic and genetic therapy that is germ cell therapy?

In germ-line therapy, the modification would be heritable, and the individual’s offspring potentially would not be affected. In somatic cell therapy, only the treated individual would have the modification.

What is a technique required for gene therapy?

Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.

Although somatic gene editing is not free from ethical, legal and social implications—it is, in many respects, similar to more traditional ‘gene therapy’ approaches in humans—it has been suggested that in many cases, the use of somatic gene editing does not challenge existing ethical, legal and social frameworks as …

What are the two types of gene therapy?

There are two types of gene therapy treatment: Somatic cell gene therapy and germline therapy. Somatic cell gene therapy involves obtaining blood cells from a person with a genetic disease and then introducing a normal gene into the defective cell (Coutts, 1998).

What are the three types of gene therapy?

Gene therapy techniques

  • Gene augmentation therapy.
  • Gene inhibition therapy.
  • Killing of specific cells.

What are some examples of gene therapy?

For example, suppose a brain tumor is forming by rapidly dividing cancer cells. The reason this tumor is forming is due to some defective or mutated gene. The therapy chosen for this case would be to use a herpes virus that has had its virulence removed, rendering it harmless.

What diseases can be treated with gene therapy?

Gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve your body’s ability to fight disease. Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS.

Why is gene therapy bad?

Gene therapy does have risks and limitations. The viruses and other agents used to deliver the “good” genes can affect more than the cells for which they’re intended. If a gene is added to DNA, it could be put in the wrong place, which could potentially cause cancer or other damage.

Is Gene therapy is a permanent cure?

Gene therapy offers the possibility of a permanent cure for any of the more than 10,000 human diseases caused by a defect in a single gene. Among these diseases, the hemophilias represent an ideal target, and studies in both animals and humans have provided evidence that a permanent cure for hemophilia is within reach.

What are the applications of gene therapy?

For example, diseases such as cystic fibrosis, combined immunodeficiency syndromes, muscular dystrophy, hemophilia, and many cancers result from the presence of defective genes. Gene therapy can be used to correct or replace the defective genes responsible.

How somatic gene therapy is done?

The technique of somatic gene therapy involves inserting a normal gene into the appropriate cells of an individual affected with a genetic disease, thereby permanently correcting the disorder.

Why is gene editing unethical?

In many countries there is a de facto moratorium on human germ line and embryo editing because such work is illegal. It is also completely unethical, not least of all because of lack of consent. … The nontherapeutic use of gene editing on human embryos was and remains unethical and illegal on every level.

What is the difference between somatic and germline editing?

While somatic gene editing affects only the patient being treated (and only some of his or her cells), germline editing affects all cells in an organism, including eggs and sperm, and so is passed on to future generations.
