Effect of anti-alpha-fetoprotein serum on human hepatoblastoma.

There is no definitive treatment of hepatoblastoma. Except for radical resection, the prognosis of unresectable cases remains pessimistic. Therefore, the development of new anticancer drugs for this tumor is urgently needed. Using the human hepatoblastoma cell line (c-HB-3) we demonstrated that horse anti-alpha-fetoprotein containing serum suppressed proliferation of the hepatoblastoma cells. This effect was dependent on the duration of exposure and the concentration of anti-alpha-fetoprotein serum.
