The expanding arena for cell therapies utilizes cell products sourced from blood, marrow, and tissues. The success/efficiency of the cell therapy is potentially affected by the periods of preservation, which includes transport of the source material and preservation of the final cell therapy product. This workshop will address the science behind current biopreservation, the pitfalls that are both recognized and often unrecognized, and new technologies that improve the final cell therapy product in terms of efficacy, quality/regulatory and cost efficiency.
