The mean Amicus CD34+ cell collection efficiency was better (p<0.05) than that of the CS-3000 Plus collection. Short-term engraftment was durable. The PBPCs collected with the Amicus separator are safe and effective for use for autologous transplant patients requiring PBPC rescue from high-dose myeloablative chemotherapy.
The third-generation bedside filter used in this study reliably reduced the level of white cell contamination to 4 log10 white cells per PC. It also lowered the levels of interleukin 8, RANTES, and C3a. The filter did not, however, remove (scavenge) the proinflammatory cytokines interleukin 1 beta and 6. The mechanism of chemokine and C3a removal by the filter is unknown, but it may be related to ionic interactions between these biologic response modifiers and the filter medium.
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.
