Targeting NK cell ontogenesis and homeostasis to disclose the mechanisms inducing the onset of hematologic malignancies

The Bone Marrow (BM) niche is a major site for the prelude of human Natural Killer (NK) cell ontogenesis. Hereupon, NK cell precursors (NKPs) enter the Peripheral Blood (PB) to differentiate into terminally differentiated cytokine producer and cytotoxic NK cells. While the characteristics and functions of mature NK cell subsets have grown, the NK cell-poiesis remains undetermined. In this project we are approaching NK cell ontogenesis at multiple layers:

  • Ex-vivo by setting up an autologous BM-niche co-culturing BM-derived stromal cells with FACS-sorted NKPs;

  • In-silico, through single cell RNA sequencing of BM and PB;

  • In-vivo by applying single-cell based pipelines to multi-parametric flow-cytometry data of NK cell immune reconstitution after hematopoietic stem cell transplantation, a model of NK cell differentiation.
