Cancers are composed of malignant cells and many different kinds of stromal and infiltrating host cells. In the past, the biochemical investigation of cancers has been based predominately upon the analysis of homogenates of whole tumors. The biochemical characterization of malignant cells from tumors would be facilitated if methods could be developed for the purification of malignant cells from tumors to be studied. Similarly, study of the host’s infiltrating cells would be greatly facilitated by the development of methods for the purification of host cells from cancers. The culture of malignant cells from solid tumors has often been complicated by overgrowth of the malignant cells by host fibroblasts (Chaudhuri et al., 1974; Feller et al., 1972; Halpern et al.,1975; Herberman and Oldham, 1975; Lasfargues et al., 1972; Mavligit et al., 1975); presumably, this difficulty could be circumvented by the culture of malignant cells purified from tumors. Since 1969 (T. G. Pretlow and Boone, 1969), our laboratory has been interested in the development of methods for the purification of single kinds of cells from cancers. While we have had some experience in the separation of individual kinds of cells from transplantable tumors of experimental animals (T. G. Pretlow and Boone, 1970; Stewart et al., 1972; Zettergren et al., 1973; T. P. Pretlow et al., 1977a,b), there are several aspects of transplantable tumors which make their separation a much easier problem than the purification of cells from primary autochthonous tumors. In this review, we shall emphasize the purification of cells from autochthonous tumors. In addition, we shall emphasize work with human tumors. Rather than review the purification of cells from tumors in general, we shall focus on those techniques that are currently used in our laboratory,i.e., sedimentation and electrophoresis.
