البرتغالية. Estudou-se comparativamente, através de métodos histoquímicos, a expressão dos componentes da matriz extracelular de tumores primitivos e metastáticos em ratos nude, xenotransplantados com células KB. Em ambas as neoplasias observou-se uma variabilidade tanto qualitativa como quantitativa dos componentes matriciais, coexistência de diferentes tipos de fibras, pouca representatividade de fibras elásticas de glicosaminoglicanas ácidas e sulfatadas e de polissacarídeos neutros, além da ausência de membrana basal.
اظهر المزيد [+] اقل [-]إنجليزي. 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.
