Inhibition of leukocyte migration by tumor-associated antigen in soluble extracts of human hepatoma
Abstract
The leukocyte migration inhibition assay was used to detect cell-mediated immune reaction of hepatoma patients. Extraction of 3 pairs of human hepatoma tissue and normal liver tissue was made by 3 M KCI solution, and soluble hepatoma antigens were used to test against leukocytes of 18 hepatoma patients by the leukocyte migration inhibition assay. In all, 25 tests were performed; most of them were allogenic, and only 3 tests were autologous. Migration inhibition was observed in 13 of 25 tests, and there were only a few cases of migration inhibition in the control groups. It was concluded that tumor-associated antigen of human hepatoma was contained in the 3 M KCI extract of hepatoma tissue and that tumor-associated antigen of human hepatoma was shared by some hepatoma patients.
