Collaborations are most welcome. Please send your proposals to Dr. John G. Delinasios or Dr. George J. Delinasios.
The following research projects are in progress at the IIAR in cooperation with other Cancer Research Centers.
A. Interactions between stromal fibroblasts and cancer cells in vitro
B. Mechanisms of development of resistance to cisplatin in vitro.
Brief Description of the Projects.
A. INTERACTIONS BETWEEN STROMAL FIBROBLASTS AND CANCER CELLS IN VITRO.
Considering recent advances and the current interest in the role of the tumor microenvironment
on cancer development and progression, this project is a continuation of earlier work:
