Abstract

The effect of interleukin-3 (IL-3) on the crypt cell production rate (CCPR) in the intestine of mice was studied using a stathmokinetic technique combined with crypt microdissection. Interleukin-3 (0.71 μgm/injection) was administered subcutaneously (s.c.) as two injections per day for 7 successive days and small mucosal pieces (duodenum, jejunum, ileum and colon) removed at necropsy were organ cultured in the presence of the metaphase arrest agent vincristine sulfate for two hours. The number of metaphases was enumerated in dissected crypts and CCPR calculated. The results demonstrated that the CCPR was significantly increased in all mucosal segments in the IL-3 treated animals compared to saline injected controls. These results suggest that the growth promoting properties of IL-3 are not restricted to hematopoietic cells when used in vivo and may directly or indirectly increase epithelial cell turnover in gut mucosa.
