The History And Application Of Cell Therapy

By Raymond Young


The many medical conditions that now plague the world have motivated research in all the four corners of the world in search for cures. Cell therapy is one of the many methods of treatment that have been found as a result of extensive research efforts. Other names used to refer to this treatment option are cytotherapy and cellular therapy. During the process of cellular materials are injected into patients. The injected materials are comprised of intact, living cells.

Cellular therapy falls under two broad categories. One is based on traditional medicine while the other one is based on conventional medicine. The variety that is founded on conventional medicine is safe and many researchers have used it successfully. The same cannot be said about the version that is founded on alternative medicine because it is very dangerous. It claims to treat diseases by injecting animal cells into patients.

It was in the nineteenth century that cytotherapy was first discovered and used. This discovery is attributed Charles Brown. Brown aimed to eliminated effects caused by aging by injecting extracts from animal testicles into people. Later, the title of inventor of cytotherapy was given to Paul following his experiments with calf embryo to treat diseases. He injected patients with materials extracted from calf embryos. Claims made by Paul about the treatment curing many people of cancer have never been verified.

Researchers discovered that pre-inoculating recipient animals with donor cells before organ transplant could prevent organ rejection. Following that discovery in 1953, successful bone marrow transplant was achieved for the first time in 1968. This happened in Minnesota.

The success of bone marrow transplants has been determined to be successful in treating various medical conditions. For instance, damaged knee cartilage can be treated successfully. Cytotherapy shows hope for the development of many kinds of treatments. In mainstream medicine, this field receives a lot of support because of the high prospects for future growth it holds.

Many types of cell therapies exist today. Some of the common examples are mesenchymal, alogeneic, neutral, human embryonic stem cells, and hematopoietic stem cell therapies. In allogeneic variety, donors and recipients of the cells are different individuals. That is why unmatched allogenic therapies are very important to pharmaceutical medicine. It is believed to be able to lead to the creation of off-the-shelf products.

A lot of controversy is coming from research in the area of human embryonic stem cells. Many countries closely regulate this field, with other banning it completely. Countries that continue to conduct experiments in this direction seek to find therapeutic applications embryonic stem cells can be put to. There are possibilities of using these cells to treat diabetes and Parkinson disease.

The history of this field is relatively short and ongoing research is underway. Mixed results of outright failures have been achieved from medical trials conducted. For concrete results to be achieved, there is still a lot to be done. However, the field is promising in many areas. Many research and non-research related organizations have invested heavily in this area of research.
