The Detroit-based human tissue bank Asterand Inc. Thursday announced the availability of a new cell line that offers researchers an important tool in the study of breast cancer. The cell line, known as MCF10DCIS.com, will be valuable for the testing of chemopreventive agents and for screening cancer causing agents, in addition to screening anticancer drugs. The cell line is being made available to commercial and academic researchers under an exclusive license from the Karmanos Cancer Institute at Wayne State University.
