Postdoctoral Position – Institut Pasteur, Paris, France

A postdoctoral fellowship is available in Dr Philippe Herbomel’s laboratory at Institut Pasteur, in Paris (France). Our lab has pionneered various aspects of the development of the hematopoietic system and resulting tissue leukocytes in zebrafish, with a strong emphasis on the in vivo study of cell behaviour. This started with the ontogeny and deployment of the primitive macrophage lineage1,2, then the neutrophilic granulocytes4 ; the emergence of the definitive hematopoietic stem/progenitor cells (HSPCs) and their journey to successive hematopoietic niches3,5, beginning with the first site of definitive hematopoiesis, which we discovered in the tail and named the Caudal Hematopoietic Tissue (CHT)3. More recently we resolved a long-standing debate in vertebrate hematopoiesis by discovering how HSPCs emerge from the ventral wall of the embryo’s aorta, through an entirely novel type of cell transition which we have named the Endothelial Hematopoietic Transition (EHT)6.

In parallel, another part of the lab focuses on the behaviour and functional properties of macrophages and neutrophils, notably upon infection1,4,7, and on the host response to viral infections8,9.

The present postdoctoral fellow will join the overall theme of developmental hematopoiesis, and may address any of the following subjects :

i) The EHT, the process by which aortic endothelial cells transform into hematopoietic stem cell : the biomechanics, cytoskeletal dynamics and cell signalling involved in this unprecedented cell transition.

ii) The long-term fate of single hematopoietic progenitors arisen from the EHT, as well as from the primitive myeloid lineage born in the yolk sac, using a genetic labelling system controlled in both time and space at the level of single cells.

iii) The cellular and molecular defects accounting for the phenotype of mutants that we have characterized - the first of their kind - as specifically devoid of microglia, the resident macrophages of the central nervous system (CNS), due ta complete and specific inability of macrophages to colonize the CNS.

Our laboratory is part of the Department of Developmental Biology of Institut Pasteur, the largest biology institute in France, situated in the centre of Paris.
Potential candidates should send a letter of interest + CV, and any questions about the position, by email to Philippe Herbomel :
