Immune Modulation Effects of Lactobacillus casei Variety rhamnosus on Enterocytes and Intestinal Stem Cells in a 5-FU-Induced Mucositis Mouse Model

Effects of Lcr35 on CD44-positive stem cells and Ki67 proliferative cells in the intestinal mucosa. CD44-positive (a) and Ki67 (b) cells after staining were counted per crypt. 5-FU significantly stimulated the expression of CD44, and the expression was restored by administration of Lcr35, though not to the S+S or S+Lcr35 levels. 5-FU increased the number of Ki67-positive cells, but there were no significant differences between the 5-FU+S and S+S groups and the 5-FU+S and 5-FU+Lcr35 groups. Values were represented as and were analyzed using one-way ANOVA.
