The recent growth in cancer immunotherapy has provided both promising treatment options for cancer patients and numerous opportunities for translational scientists to identify and develop new classes of immunomodulatory therapeutics.
As these agents target the complex human immune system in a multitude of different ways, conventional xenograft and syngeneic tumor models may not be fully suitable for their evaluation. There is an increasing demand for preclinical models which are capable of testing human-specific immuno-oncology agents.
To meet this need, CrownBio has developed a platform of PBMC-humanized mouse tumor models, which have been characterized to address questions such as synchronization of tumor/PBMC inoculations, optimal inoculation route and cell number, PBMC donor dependence and specificity, and the impact of donor HLA type on the engraftment of immune or tumor cells.
