Abstract: Maintenance of quiescent hematopoietic stem and progenitor cells (HSPC) in culture without the addition of exogenous growth factors is an important aspect in clinical hematology. A recent report described the ability of Flt3 receptor-interacting lectin (FRIL) in the maintenance of cord blood (CB) derived progenitors in vitro. Since FRIL is a mannose binding lectin, the effectiveness of four such lectins of well-characterized specificities on the preservation of HSPC of CB origin have been examined. The HSPC preservation activity of lectins was assessed by in vitro colony forming unit (CFU) and long-term culture initiating cell (LTC-IC) assays. It was found that all four lectins had a HSPC preservation activity at least up to 30 days in culture without addition of exogenous growth factors. The results indicate that use of such lectins may provide a cost effective method of HSPC maintenance for clinical use.

Abstract: A collector for fecal discharge is provided comprising a self-expanding resilient collection component, a housing sheath and a transit component. The collection component has an open proximal and distal end and a lumen connecting them. The component comprises interconnected resilient arms circumscribing its contour, wherein adjacent arms are resiliently biased away from each other for exerting outwardly radial pressure for expanding and anchoring the component to rectal walls upon deployment. The housing sheath comprises a flexible and resilient material overlaying at least one of inner or outer contour of collection component without interfering with or blocking its ends or lumen. The transit component provides a conduit for fecal discharge to migrate from collection component to a receptacle and comprises a flexible, tubular sheath having a first open end connected to a second end by a lumen, wherein the first end engages with the proximal end of the collection component.
