Immuno-Oncology Platform - Proprietary Models
Field of Application
Today, cancer research tends to focus on development of novel cancer immunotherapies. Syngeneic tumor models are advantageous providing a functional immune system to assess novel immunotherapeutic approaches. While classical syngeneic mouse models are based on the implantation of cultured cell lines, ProQinases’ mouse-derived isograft (MDI) tumor models are propagated in mice only. Hence, the major advantage of these novel spontaneous-derived or carcinogen-induced MDI tumor models is the preservation of primary tumor phenotype and intratumoral immune cell populations.
