our studies have established that at least one of the pathways for the release of ig from hybridomas , b-cell lines , and normal splenic b-cells is via a polar multivesiculated structure that we have termed isv , and that the sig can be released either as a free form of the protein or packaged within a satellite vesicle which may release the sig later and perhaps at considerable distance from the cell that produced it .
