Somatic cell therapy

What is the difference between germline and somatic cell gene therapy?

Somatic therapies target genes in specific types of cells (lung cells , skin cells , blood cells , etc), while germline modifications, applied to embryos, sperm or eggs, alter the genes in all the resultant person’s cells . Somatic cell modifications are noninheritable, affecting only the treated individual.

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.

Is somatic gene therapy legal?

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).

Why is gene therapy illegal?

Because people who would be affected by germline gene therapy are not yet born, they can’t choose whether to have the treatment. Because of these ethical concerns, the U.S. Government does not allow federal funds to be used for research on germline gene therapy in people.

How does somatic gene therapy work?

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 does somatic mean?

1 : of, relating to, or affecting the body especially as distinguished from the germplasm. 2 : of or relating to the wall of the body : parietal.

What is somatic editing?

The Importance of Somatic Cells Over the past decade, researchers have advanced genome editing technology to allow for precise changes to the DNA code inside live cells. Using this technology, scientists could edit disease-causing DNA within the body’s non-reproductive cells, known as somatic cells.

What is a somatic gene?

Somatic mutation, genetic alteration acquired by a cell that can be passed to the progeny of the mutated cell in the course of cell division. Somatic mutations differ from germ line mutations, which are inherited genetic alterations that occur in the germ cells (i.e., sperm and eggs).

How much is gene editing?

Developing a gene therapy can cost an estimated $5 billion. This is more than five times the average cost of developing traditional drugs.

Is Gene Therapy legal in the US?

Gene therapy is currently available primarily in a research setting. The U.S. Food and Drug Administration (FDA) has approved only a limited number of gene therapy products for sale in the United States .

Should we use gene therapy?

Advertisement. 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.

How gene therapy is done in human?

Gene therapy is a technique in which a functioning gene is inserted into a human cell to correct a genetic error or to introduce a new function to the cell. Many methods, including retroviral vectors and non-viral vectors, have been developed for both ex vivo and in vivo gene transfer into cells.

Why gene therapy is expensive?

The main reason gene therapy is so expensive , however, may be the paradigm used in the price-setting strategy. The cost of production is weighed against the value of a life saved or the improved quality of life over a specified timeframe.

Can genetic disorders be cured?

Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured . However, approaches may be available to treat or manage some of the associated signs and symptoms.
