About and Activities

Learn more about the Cellular Therapies Working Party and its activities.


  • We cover all the different aspects of cellular therapies
  • We provide a platform for discussion, especially when related to transfusion and provide a resource for learning and the exchange of ideas
  • We act as an expert group to advise ISBT on matters related to cell therapy
  • We also represent ISBT on collaborative work with other international societies including AABB, ISCT, ICCBBA
  • We are available to offer expert practical and scientific advice to ISBT members who may want to start stem cell processing and cell therapy programmes

Activities and projects

Human Platelet Lysate – Current Standards and Future Developments workshop

Next workshop

The workshop will be held on March 22-23, 2022 in Zurich and shall provide a forum for transfusion experts who manufacture the product, scientists who are investigating its therapeutic and cell culture potential to discuss the latest updates on the field, and also with the regulators on how to classify this blood derived product.
