The Stem Cell Dilemma

Approximately 3,000 people in the stem cell dilemma die each day while waiting for organ transplantation (D'Agnese). In addition, in the United States, there are still more than 66,000 people on the list of organ donors, but few people see their names on the list ("improvement"). Many think that nothing can be done about this sad truth. But that is not the case. Research on stem cell research shows a solution to this fatal problem. By effectively utilizing stem cells, we can solve many diseases and medical problems.

More than ten years ago, Japanese scientists discovered a method of ingesting any adult cells such as skin cells and fibroblasts and converting them to stem cells. None of the embryos has a moral dilemma! This process requires the insertion of genes with specific properties into somatic cells. Since these genes are inserted from outside the cell, they are called transgenes. Fortunately, this process is very robust and can be used from the patient's own cells. The bad news is that some of the inserted genes may cause cancer. However, the transgene is terminated as part of the process of transforming the stem cell into the desired cell type. It is said that they are silent

Adult stem cells may be the answer to moral dilemmas! "Although we are developing the story of hES, adult stem cells are quietly developed in many academic laboratories and biotechnology companies, and adult stem cells spread throughout the body from the skin surface to the liver" , Especially for liver disease and heart disease, adult cells look very promising, but if you are seeking a solution for Parkinson's disease or diabetes, "R Research Ronald Mackay National Institute of Health I am talking. I will say that the cells that provide the best method are fetuses and embryos. "Nevertheless, adult stem cells have been tested in human clinical trials."

Various types of stem cells have been studied: adult stem cells found in HSC, bone marrow and blood; adult stem cells found in several parts of the body including MSCs, bone marrow, skin and adipose tissue; nerves responsible for brain repair Stem cell neural insulation myelin special stem cells These are other stem cells such as MSC, iPSC (which is designed to produce many kinds of cells from adult cells) and hESC (stem cells naturally producing each kind of cells in the body) It is derived from a type of stem cell. . 8
