Description
SupB15 cells are highly sensitive to Mitoxantrone treatment. To obtain drug resistant subpopulations, SupB15 cells were incubated in normal medium or BMSC derived conditioned medium, treated with 10nM of Mitoxantrone for 6 days. SupB15 cells in normal medium could not survive. a small population of SupB15 cells in conditioned medium group survived the treatment and ecpanded, termed as SupB15-MR.
