      Translation of cell and gene therapies from pre-clinical experiments to clinical trials and final drug licensing brings requires the development, verification and even validation of the assays essential for the definition of the drug product. The technical and scientific challenges in doing this are far greater than they seem at first and are compounded by a lack of approved standards for assays used to support (c)GMP manufacture. This paper highlights some of those challenges and proposes solutions based on the experience of our colleagues using similar assay platforms in regulated pathology laboratories.
