Clinical Cellular Therapy Research Laboratory (LTCC)


The Institut Bordet Clinical Cellular Therapy Research Laboratory (LTCC) is dedicated to fundamental and translational research in the fields of haematology and immunology cellular therapy.

The LTCC’s main objectives concern:

  • study of the interaction between leukaemic cells and their microenvironment;
  • establishment of new prognostic factors;
  • development of new therapeutic strategies.

Within the field of cellular therapy, the LTCC is studying the functional characterisation of mesenchymal stromal cells obtained from different tissues and their manipulation with a view to increasing their therapeutic potential.

Research projects

Project 1

Discovering new altered signalling pathways leading to Richter syndrome in patients affected by chronic lymphoid leukaemia via whole genome sequencing.
