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."

Well you've lumped all Conservative Republicans into a convenient stereotype of religious wackos, so I guess I have no choice BUT to be put on the defensive. I also don't have to be "religious" to take offense to your insanity when it comes to them. Even if someone said "we should kill all Liberals" I would not be on board with that. It's called maturity and empathy, something you should look up. Just because I don't agree with someone's ideology or lifestyle, doesn't mean I should feel that it's okay if they were killed off or marginalized in some other fashion.
You're talking about having the power to make hundreds of millions of people "not exist" in a casual manner like someone would talk about going out to eat. And you question ME? Something is VERY wrong with you. It's not "ironic" that I called you Hitler. Replace Jews with "religious" people and there you have it. The mentality is exactly the same. You are talking about genocide.
Social Darwinists, "Christian Taliban"....what the hell are you even talking about? Do you listen to yourself? These are all in your head.
