Separation of hematopoietic stem and progenitor cells from human peripheral blood through polyurethane foaming membranes modified with several amino acids
Abstract:The separation of hematopoietic stem and progenitor cells (CD34 þ cells) from peripheral blood was investigated using foamed polyurethane (PU) membranes modified with several amino acids. CD34 þ cells were collected by first allowing the blood to permeate through the membranes, and then passing the recovered solution through the membranes. Optimal conditions for the separation of CD34 þ cells were investigated. The highest recovery ratio of CD34 þ cells was obtained using three sheets of PU membranes having ca… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
