Abstract
A method for removing tumor cells from tumor cell-contaminated stem cell products is disclosed. One embodiment of the method relies on an in-line filtration device that includes a tumor cell reduction filter means, preferably comprised of one or more tumor cell reduction filter pads. The tumor cell reduction filter means provides at least a ten-fold reduction in tumor cells while allowing for at least a 30% recovery of stem cells in a filtered stem cell product.
