Figure 5. In vitro assay of BrdU incorporation. The BrdU incorporation rates were examined with rmSCF-stimulated MCECs from WBB6F1+/+, SCF mutant, and c-kit mutant mice. The BrdU incorporation rates are normalized to the number of non-stimulated controls
(0 ng/ml rmSCF). Error bars represent the standard error (n=4). There were no significant differences between stimulated cells
and non-stimulated controls (p>0.05, Man-Whitney U test). +/+=WBB6F1+/+ mice, W/Wv=c-kit mutant mice, Sl/Sld=SCF mutant mice.
