derives from/develops from KB cell KBv200 cell 2011-09-01T08:51:13Z A multidrug-resistant clone of human oral epidermoid carcinoma KB cells was isolated by stepwise selection on exposure to increasing doses of vincristine. The final clone, KBv200, obtained after ethylmethane sulfonate mutagenesis showed 156-fold higher resistance to vincristine than KB cells. The cells were also cross-resistant to paclitaxel and adriamycin. BTO:0005196 BrendaTissueOBO XPMUser
