Research Abstract	We detected the significant infiltration of neutrophils to several tissues in Cas-L-deficient p210Bcr-Abl transgenic mice. Cas-L-deficient neutrophils showed the activated migration and the decreased adhesion ability. Moreover, in homing assay, bone marrow cells from Cas-L-deficient mice were detected in the spleen more than cells from wild-type mice. In proliferation assays and colony assays, there are no differences between Bcr-ABl positive cells and Cas-L-deficient Bcr-Abl positive cells Therefore, the aberrant cell motility was considered to be the reason of extreme neutrophil infiltration in Cas-L-deficient p210Bcr-Abl transgenic mice.
