The vasculature of xenotransplanted human melanomas and sarcomas on nude mice. I. Vascular corrosion casting studies.

The vascular system of xenotransplanted human melanomas and sarcomas on nude mice was studied by means of microorrosion casting. In summary, the vascular system of xenotransplants can be described in termes of a simply structured system, lacking not only a hierarchy with respect to wall formation but also to vascular distribution. Thus, the vasculature clearly differs from that in normal tissues.
