It is naturally understandable that Germany is a little slower than other countries around the world to venture into stem cell or genetic research, due to its history, during the Nazi regime in the 1930s and 1940s. As a matter of fact, Germany has strict laws on stem cell research, as well as restriction of using embryonic cells for any type of research due to this sensitive issue that continues to hang over any studies in genetic research or engineering.

Because stem cell therapy promises new hope in the treatment of diseases through the growth of new tissues and organs from pluripotent or differentiated stem cells, Sweden has taken it upon itself to develop techniques that will grow brain cells in a laboratory that may one day be used to help provide therapies and treatments for patients suffering from Parkinson's disease. This difficult endeavor, while in its infancy, will face multiple problems and obstacles, such as how to grow such neurons from stem cells that will not result in a tendency to form tumors or clumps. Studies have moved away from using embryonic stem cells, and if studies and developments in this method are successful, they may ultimately lead to clinical trials.

The process to transform adult human non-embryonic skin cell tissues into cells that do resemble embryonic stem cells requires several basic ingredients. Researchers in Massachusetts, in the United States, have successfully converted cells that have several of the genetic features as well as growth factors and physical characteristics of stem cells that are typically only found in embryonic stem cells. However, these stem cells can differentiate, or change, to create and produce other tissue types including heart tissues as well as nerve tissue and skin tissue.

International stem cell Corp., a California biotechnology company that focuses on developing research and therapeutic products, has announced that it will be available to provide corneal epithelial cells derived from parthenogenetic stem cells and a specific type of human skin cells (keratinocytes) for use in clinical trials that focus on developing tissue transplant technology and therapies to improve a vision condition called photorefractive keratectomy, a.k.a. PRK.

Recent discoveries in adult stem cell research have greatly encouraged the scientific community in the potential for using skin cells, bone marrow cells, and blood stem cells instead of embryonic stem cells for a variety of treatments and procedures. However, various aspects still must be taken under consideration.

Umbilical stem cord blood cells used to treat those with blood-borne deficiencies or diseases that used to require bone marrow transplants have been used with greater success in past years. While most bone marrow transplant patients usually require a perfect match among six antigens, use of the umbilical cord blood transplants can decrease that number to four.
