Abstract

Specimens of human tumors were taken from the operating room and directly heterotransplanted to chick chorioallantoic membranes. Seventy‐one percent of the eggs survived the procedure and 41% of the tumors appeared viable after 1 week. Micro scopically, the first‐generation heterotransplants resembled the parent tumors. Many specimens showed evidence of growth, but in most of them there was also some degree of necrosis. The necrosis increased with serial heterotransplantation, so that tumor propagation usually was not possible beyond the second to third transplant generation; nevertheless, it was found that almost any histological type of intracranial tumor could be grown for short periods of time at least on the chick chorioallantoic membrane.

## Abstract Cultured human rhabdomyosarcoma (RD) cells were seeded on the chorioallantoic membrane of embryonated hens' eggs at the 10th to 12th day of incubation. When the membranes were harvested after 18 to 19 days' incubation, tumors had formed in eggs seeded with 5 Γ— 10^5^ to 10 Γ— 10^6^ RD cel

## Abstract It has generally been assumed that tumors do not induce lymphangiogenesis and only very recently animal models have been presented showing tumor‐induced lymphangiogenesis. We have grown two types of rat tumor cells, 10AS pancreatic carcinoma and C6 glioma cells, on the chorioallantoic m

## Abstract In order to address the molecular signature of human glioma, we investigated the polymorphism of 5β€²UTR of the mRNA of Contactin, an adhesion molecule which plays a role in the invasive behavior of these tumors. Contactin mRNA is identified by RT‐PCR and a strategy based on rapid amplifi
