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."

They do not deserve to live? Because they do not agree with your point of view? You're no better than they are. Your opinions don't matter any more. You're just a mortal too, and a foolish, hateful, one at that. Your very speech is like a mirror image of the kind you claim to abhor. You are at least as closed-minded and bigoted as your counterparts on the far other side of the spectrum, and equally blind to this fact as well.
I've got news for you. To use your own words: You're STILL just a "clump of cells", meatbag. With an attitude like yours, I wonder if it's not too late to abort you. You know, for science, nothing immoral about it.
