Abstrakt: Mouse lymphoblasts generated in vivo by a topical application of the contact sensitizer oxazolone or by the contents of the gut lumen were separated by discontinuous density centrifugation on Percoll gradients. A 3-step gradient was used to divide the cells into two subpopulations. For cells from oxazolone stimulated lymph nodes, the low density band contained 20-30% of the initial cell number applied to the gradient; 25-40% of this population were in S phase and nearly all the large and pyroninophilic cells were confined to this layer. The high density step cells (70-80% of initial cell number) were predominantly small lymphocytes with less than 0.5% in S phase. Similar results were obtained using cells from picryl chloride stimulated lymph nodes or from mesenteric lymph nodes.
