However, 3-week post-injection of GCSF into AML (AML + GCSF), CYT (CYT + GCSF) and AML + CYT (AML + CYT + GCSF) significantly decreased the percentages of seminiferous tubules with apoptotic cells compared to AML-, CYT-, (AML + CYT)-treated groups (Figure 4A,B). The gene discussed is CSF3; the disease is acute myeloid leukemia.
