Furthermore, preliminary work also performed to examine whether PI3K/AKT signal transduction pathway was activated in the process of refractory leukemia development. Materials and methods An immortalized human bone marrow stromal cell line, HS-5, was introduced to establish a bi-phase culture system for the cultivation of B-lineage precursor leukemia cells. ELISA and RT-PCR were used to investigate the expression of VEGF and its receptors in the leukemia cell lines and primary childhood leukemia cells in different treated groups. Flow cytometory method and immunofluorescent staining were employed to examine the apoptosis signals both in the VP16 treated and untreated leukemia cells. Western blot was utilized to explore the PI3K/AKT activated status in the drug induced or uninduced leukemia cells and lymphocytes from healthy donors.
