Should You Care About Stem Cell Research
To understand the controversy, first understand cell function
dLife founder Howard Steinberg recently interviewed Speaker of The House Nancy Pelosi to discuss the use of stem cells for research (the Stem Cell Research Enhancement Act of 2007; H.R.3) . This bill was approved by the House of Representatives on January 11, 2007, but President Bush has threatened to veto it. If it survives his veto, the bill will increase the number of stem cell lines (families) that can be used in federally funded research. What could this mean to you?
What are Stem Cells?
Stem cells are unique cells in our bodies that have three special abilities:
1. They can develop into cells that have specific functions, such as heart cells that help pump blood, red blood cells that deliver oxygen, or nerve cells that transmit messages.
2. They can divide and take whatever role is needed. When a stem cell divides, each "daughter" cell either remains a stem cell or becomes another type of cell with a more specific function, such as a red blood cell or a brain cell.
3. In addition to dividing, they can renew themselves for very long periods of time. Regular cells cannot do this.
Stem cells come in two types: adult and embryonic. Embryonic stem cells have the greatest potential. They have no specific identity and can develop into different types of cells that may have been damaged from an injury or from diseases such as Parkinson's and Diabetes. These ultra-flexible cells exist in 5-day old human embryos.
Adult stem cells already have some identity and aren't quite as flexible. They can develop into other types of cells, but only if they are placed in a part of the body that resembles where they came from. Adult brain stem cells that are placed into a pancreas will probably not develop into pancreatic cells. But embryonic stem cells that are placed in the pancreas will develop into new pancreatic cells.
Many people are concerned about the source of embryonic stem cells. When many infertile couples try to conceive, they use a procedure called in-vitro fertilization – they donate egg and sperm samples to a lab where they are fertilized. Then several fertilized eggs are implanted into the female partner. Not all will successfully grow into fetuses, but many will. Unused fertilized eggs will never become babies because they are never placed into wombs. They are frozen, tossed out, or destroyed. If not used, they will die naturally within a few days.
Is it wrong to use embryos that will be destroyed to help save lives? This is what must be decided. Listen to the Howard Steinberg's interview with Speaker of the House Nancy Pelosi on dLife.com and become informed. We are about to embark on a new chapter in medical history. We must enter it with great hope, care, and information.

As I mentioned in an earlier post, one of the benefits that made it cost-effective for me to go with the real healthcare (HSA) plan rather than the phony (HRA) plan is that my company is now covering "preventative" medicines at $0 copay. The formulary for these, as stated by CVS/Caremark (my pharmacy benefits provider), covers all test strips, lancets, and control solutions. I dutifully get my doctor to write up prescriptions for all of my testing needs, submit...
