简介：
Overview
This article describes a method for producing exogenous cytokines in patient-derived xenograft (PDX) mice through weekly intraperitoneal injections of a cytokine-transduced stromal cell line. This technique enhances the utility of PDX models, allowing for both transient and sustained cytokine delivery.
