A PEDIATRIC ONCOLOGIST CHILDRENS CANCER DOCTOR OPINION ABOUT OBAMA STEM CELL PLAN
In his blog the pediatric oncologist, Dr. David, discusses why he thinks President Obama's decision to liberate some stem cell research is a good idea. "As I discussed in a prior post, a stem cell is a primitive cell that is capable of generating more “daughter” cells with more specific function as well as making more copies of themselves. Every organ and tissue in your body contains stem cells.
As the most mature cells die, they are replaced by cells derived from these “organ stem cells,” which also continuously replenish themselves.
Stem cells such as these are often referred to as “adult stem cells” because they are found in adult humans. There are also “umbilical cord stem cells” which are found in the blood in the umbilical cords of newborn babies and many oncologists believe that there are “cancer stem cells” that drive the growth and spread (“metastasis”) of tumors".
