Abstract

A comparative study of metastic and primitive tumors extra-celular matrix in nude rats, xenotransplanted with KB cells, using histochemical methods, was carried out. In both primitive and metastatic tumors it was possible to observe a qualitative and a quantitative variation of matricial components; coexistence of different kinds of fibers; small representation of elastic fibers; presence of acid and sulfated glycosaminoglycans and neutral polysacharyds, and also absence of basal membrane. It is suggested a small interaction between collagenic components and proteoglycan of primary tumors and the proteoglycan, whereas in métastasés this interaction is increased.
