✦ Synopsis

Abstract

Tumor‐specific blocking factors were detected by the macrophage migration inhibition technique, in thoracic duct lymph collected 24 to 48 h after transplantation of two methylcholanthrene‐induced tumors into mice. Drainage of lymph in this period, with replacement of the cells, inhibited subsequent tumor growth. Blocking factor was not found in lymph from mice with a third tumor, when examined at the same stage, and thoracic duct drainage did not affect tumor growth in this instance. The results indicate that blocking factor has a function in vivo and that decreasing its concentration in a tumor‐bearing host at a critical stage can suppress tumor growth.

Insulin-like growth factor-1 (IGF-1) and its receptor are believed to play an important role in mitogenesis and neoplastic transformation. The purpose of this study was to further examine the role of IGF-1 during tumor promotion in mouse skin. HK1.IGF1 transgenic mice, which overexpress IGF-1 in epi
