The Survey on Cellular and Tissue-Engineered Therapies in Europe in 2016 and 2017

Abstract

This report describes activity in Europe for the years 2016 and 2017 in the area of cellular and tissue-engineered therapies, excluding hematopoietic stem cell treatments for the reconstitution of hematopoiesis. It is the eighth of its kind and is supported by five established scientific organizations. In 2016 and 2017, a combined 234 teams from 29 countries responded to the cellular and engineered tissue therapy survey; 227 teams reported treating 8236 patients in these 2 years. Indications were categorized in hematology/oncology (40%; predominantly prevention or treatment of graft vs. host disease and hematopoietic graft enhancement), musculoskeletal/rheumatological disorders (29%), cardiovascular disorders (6%), neurological disorders (4%), gastrointestinal disorders (<1%), as well as miscellaneous disorders (20%), which were not assigned to the previous indications. The predominantly used cells were autologous (61%). The majority of autologous cells were used to treat musculoskeletal/rheumatological (44%) disorders, whereas allogeneic cells were mainly used for hematology/oncology (78%). The reported cell types were mesenchymal stem/stromal cells (MSCs) (56%), hematopoietic cells (21%), keratinocytes (7%), chondrocytes (6%) dermal fibroblasts (4%), dendritic cells (2%), and other cell types (4%). Cells were expanded in vitro in 62% of the treatments, sorted in 11% of the cases, and rarely transduced (2%). The processing of cells was outsourced to external facilities in 30% of the cases. Cells were delivered predominantly intravenously or intra-arterially [47%], as suspension [36%], or using a membrane/scaffold (16%). The data are compared with those from previous years to identify trends in a rapidly evolving field. In this edition, the report includes a critical discussion of data collected in the space of orthopedics and the use of MSCs.

Impact statement

The surveying of cell and tissue-engineered therapies is a relevant instrument to capture developing trends and monitor advances in the field, based on effective treatments performed.
