The new suspension method allows stem cells to be collected in larger numbers instead of being scraped off of a surface

Researchers from the University of Toronto's Institute of Biomaterials and Biomedical Engineering (IBBME) have created a new method for growing stem cells in larger quantities.

David Fluri, a postdoctoral researcher at IBBME, and Peter Zandstra, a professor at IBBME, have developed a new suspension method for growing stem cells, which allows for the collection of greater numbers of stem cells and increases the chance of obtaining viable cells in a cost-effective way.

Traditionally, stem cells are grown on surfaces that need to be scraped and are then differentiated from other kinds of cells to avoid cell death. However, this method doesn't produce enough viable stem cells from each culture, and the high cost to use this method doesn't match the results.

But now, Fluri and Zandstra have combined the stem cell creation process with a bioreactor, which provides stable environments for such processes. The cells were also grown in suspension, making the process more stable and safer for more viable cells.

By doing this, mouse cells were reprogrammed into pluripotent stem cells, which can become any kind of cell. They were then changed into cardiac cells.

Fluri and Zandstra hope that this new technique can be used to eventually treat heart disease. It is designed to work with large scale processes and provide the quantity needed for successful stem cell research and drug development.

"This is an enabling technology," said Zandstra. "It takes something we showed we could do before at low efficiency but not at such numbers that could be used in manufacturing."

Here's rest of the stuff that Bush did:
In April 2004, 206 out of 500 members of Congress signed a letter urging President Bush to expand federal funding of embryonic stem cell research beyond what Bush had already supported.

In May 2005, the House of Representatives voted 238-194 to loosen the limitations on federally funded embryonic stem-cell research — by allowing government-funded research on surplus frozen embryos from in vitro fertilization clinics to be used for stem cell research with the permission of donors — despite Bush's promise to veto the bill if passed. On July 29, 2005, Senate Majority Leader William H. Frist (R-TN), announced that he too favored loosening restrictions on federal funding of embryonic stem cell research. On July 18, 2006, the Senate passed three different bills concerning stem cell research. The Senate passed the first bill (Stem Cell Research Enhancement Act), 63-37, which would have made it legal for the Federal government to spend Federal money on embryonic stem cell research that uses embryos left over from in vitro fertilization procedures. On July 19, 2006 President Bush vetoed this bill. The second bill makes it illegal to create, grow, and abort fetuses for research purposes. The third bill would encourage research that would isolate pluripotent, i.e., embryonic-like, stem cells without the destruction of human embryos.

In 2005 and 2007, Congressman Ron Paul introduced the Cures Can Be Found Act, with 10 cosponsors. With an income tax credit, the bill favors research upon non embryonic stem cells obtained from placentas, umbilical cord blood, amniotic fluid, humans after birth, or unborn human offspring who died of natural causes; the bill was referred to committee. Paul argued that hESC research is outside of federal jurisdiction either to ban or to subsidize.[43]

Bush vetoed another bill, the Stem Cell Research Enhancement Act of 2007, which would have amended the Public Health Service Act to provide for human embryonic stem cell research. The bill passed the Senate on April 11 by a vote of 63-34, then passed the House on June 7 by a vote of 247-176. President Bush vetoed the bill on July 19, 2007.

On March 9, 2009, President Obama removed the restriction on federal funding for newer stem cell lines.

As you can see, he may have started an initiative, but then he vetoed progress and stifled research. This is due to his religious beliefs, and he's a POS.

Let's come back to Roe vs. Wade. According to UDHR and also our constitution, the value of each one of our lives is equal. We also all have a right to privacy. Now since the ruling says that a woman's right to privacy is more important than the life of a fetus up to its viability, that clearly means that the fetus is not considered to be a human, otherwise its life wouldn't be less important than a woman's right to privacy, until it's viable. So the viability is being used to determine if it really is a human worthy of the protections of the constitution or not.

A blastocyst, which is a lot removed from a viable or close to viable human fetus, and has not even undergone cell differentiation, is surely not a human being according to our laws. However Bush's laws (aka the Bible) say otherwise and he vetoed expanding stem cell research.

About the Bible, proving things do not work that way. I do not have to prove that the Bible is a work of fiction, you have to prove that it isn't. You have to prove that Jesus is a real supernatural being and all the other crap he did in the Bible, not the other way around. Your stories about Jesus have just as much credibility as my stories about a dragon in my garage. Both are equally (un)likely.
