Abstract:Approximately half of the colony-forming units-culture (CFU-C) from normal peripheral blood are eosinophilic. The purpose of our study was to determine: (1) whether progenitor cells committed to eosinophil or neutrophil maturation would be differentially affected by feedback inhibition, and (2) whether mature eosinophils added to the feeder layers of the culture would inhibit the proliferation of CFU-C in a manner similar to that described for neutrophils. Concentrated eosinophils and neutrophils, obtained by … 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.
