quantitative studies of mcf-7 cells ( derived from human breast adenocarcinoma ) and cv-1 cells ( from normal african green monkey kidney epithelium ) , using the permeant cationic compound tetraphenylphosphonium ( tpp ) , in conjunction with fluorescence microscopy using rhodamine 123 ( rh123 ) , indicate that the mitochondrial and plasma membrane potentials affect both uptake and retention of these compounds .
