Figure 6. In vitro assay of attachment mouse corneal epithelial cells (MCECs). The effect of the rmSCF on the attachment of MCECs from WBB6F1^+/+, SCF mutant, and c-kit mutant mice was examined. The MCECs were stimulated with or without 1, 10, or 30 ng/ml of rmSCF, and the results are normalized to the number of non-stimulated controls (0 ng/ml SCF). Error bars represent the standard errors (n=8). *p<0.01, ⁺p<0.05 (Man-Whitney U test) against non-stimulated controls. +/+=WBB6F1^+/+ mice, W/W^v=c-kit mutant strain, Sl/Sl^d=SCF mutant strain.
