The 22nd CHO Congress brought together 141 participants who exchanged and debated in a very dynamic way throughout the conference. In addition to the national and international guest speakers, a large place was given to short oral communications selected on summary. Many young researchers (doctoral and post-doctoral students) selected on the scientific qualities of their abstract saw their stay subsidized and presented their research work orally. The poster session was also held in a good mood and gave rise to many discussions. Thank you to the participants who made this conference an excellent and very enriching scientific meeting and thank you to the sponsors for their generous support.


CHO congresses aim to follow scientific developments in hematopoiesis and oncogenesis thanks to the participation of renowned guest speakers whose work sweeps across the main aspects of current events in the field. The issues addressed at the 22nd CHO Congress related in particular to the biology of hematopoietic stem cells and progenitors (both in the embryo and in adults), normal and pathological hematopoietic niches, the regulation of hematopoiesis by intrinsic and extrinsic factors, the molecular mechanisms responsible for the development of blood pathologies, as well as the identification of biomarkers, therapeutic targets or new treatments. Several studies have notably contributed to the understanding of the mechanisms of control of normal hematopoiesis whose deregulation is at the origin of the emergence of myeloid neoplasms. These different fundamental questions have been addressed by different in vivo, cellular (in particular, single cell scale) and molecular approaches.
