CSF1 and acute myeloid leukemia: However, 3-week post-injection of GCSF into AML- (AML + GCSF), CYT- (CYT + GCSF) and (AML + CYT)- (AML + CYT + GCSF) treated mice significantly increased their expression in testicular homogenates compared to AML-, CYT- (except for SCF and MCSF which were similar to CYT-treated group) and (AML + CYT)-treated group (Figure 6A–C).
