Cord blood stem cell units have been shown to be a suitable alternative to adult bone marrow for the treatment of many diseases, including sickle cell anemia.

In fact, many nations currently refuse to support embryonic stem cell research of any kind.

Using adult stem cells drawn from bone marrow and umbilical cord blood system cells, scientists have discovered new treatments for scores of diseases and conditions such as Parkinson's disease, juvenile diabetes, and spinal cord injuries.

To date, embryonic stem cell research has not produced a single medical treatment, where ethical, adult stem cell research has produced some 67 medical miracles.

I wholeheartedly support umbilical stem cell research, but also support embryonic stem cell research.

I'm involved in Project ALS which is trying to get money for stem cell research. That's one I've been pretty involved with because if you can cure that, you can cure so many other diseases.
