the volume of the lysosomal compartment in cultured human skin fibroblasts was estimated from the distribution between the cells and the medium of tracer amounts of labelled methylamine and chloroquine , which accumulate in the lysosomes , 2,2-dimethyloxazolidine-2,4-dione , which accumulates in the soluble cytoplasmic compartment relative to the lysosomes , and sucrose , which is excluded by the cells .
