O'Neill Lab - Stem cells and immunology

Migrating kidney cell

Research in the O'Neill Group is focused on the following:

  • Hematopoiesis and microenvironments supporting stem cell differentiation
  • Spleen as a site for extramedullary hematopoiesis
  • Development and function of dendritic cells in normal and disease states.

Medical research is always portrayed to the public in terms of diseases and the search for cures and exciting new therapies. However, Professor Helen O’Neill admits that the process of research is tough and much more esoteric
