Where does Certis source tissues for developing its PDX tumor bank?

Unlike many contract research organizations (CRO)s, Certis has developed its commercial cancer models from tissue derived from North American patients. Some models originate from personalized studies Certis has conducted for individual patients; others are developed from tissues or research models acquired through alliances with research institutions. Most models in the Certis tumor bank have been developed from tissue acquired within the last five years and many have been pretreated with current standard-of-care therapies.
